UNLV medical school brings a virtual touch to anatomy studies – Las Vegas Review-Journal

Posted on by

Dr. Neil Haycocks twists and turns the 3-D image to review the head and neck CT scan from a variety of angles.

Even without being a doctor, its easy to tell from the clear, virtual image that the man has suffered a serious injury.

I dont know exactly what happened to this person, but my guess is that they were struck with some sort of blunt object, Haycocks said as he pointed out a fractured mandible and a depressed bone.

As he sliced through the patients skull to further examine his injuries, Haycocks demonstrated a crucial benefit to the virtual anatomy tables at UNLVs new School of Medicine the ability to examine a patient without destroying vital organs.

With a touch of a button, the skull was whole again.

The touchscreen tables, which replace cadavers that would be found in a traditional anatomy lab, are just one example of the innovative curriculum the first class of 60 students will encounter when they set foot in the school on July 17.

THE BACKBONE

UNLV wont be the first school to use anatomy tables.

But its the schools commitment to teaching the subject that sets it apart, according to Dr. Ellen Cosgrove, vice dean for academic affairs and education.

Weve decided to make the virtual anatomy the backbone and the framework of our anatomy instruction, she said.

Haycocks, who learned human anatomy in a traditional lab, said cadaver dissection is limited in its educational benefits.

You spend hours cutting through tissues, trying to find this or that, Haycocks said. Sometimes its well preserved, and sometimes it isnt. Sometimes you accidentally destroy whatever it is youre looking for, and sometimes youre just lost you never find out whats going on. Its a very lengthy and time consuming process.

Haycocks previously taught at a college where he oversaw a cadaver lab. He said that he loved working with the students and seeing their reactions as they cut open a human body.

Thats enjoyable for me at least, but its really inefficient, he said.

The technology can display images of the body from a variety of perspectives and angles, including 2-D cross-section and 3-D rotation.

With a slight tap, Haycocks lit up the screen with millions of tiny blue channels, illustrating a patients veins.

And in terms of instruction, virtual anatomy is beneficial because everyone gets the same information. Its also less time consuming and costs much less than a traditional cadaver lab, which runs upward of $10 million.

If you talk to most people who teach anatomy nowadays, they would agree, perhaps grudgingly, that in well under 100 years, nobody is going to cadaver dissection anymore, Haycocks said.

COMBATING INERTIA

Haycocks sees several benefits from a curriculum standpoint, but he also points out a few flaws to the system.

For me, the main disadvantage is that you dont have that first patient experience with a real human body, he said.

Given that a first patient often resonates with students, others in the medical community might also question the virtual anatomy approach.

A lot of education in general, and medical education in particular, theres a lot of inertia, Haycocks said. Things have been done a certain way for the last 150 years, and by God, the faculty had to do it a certain way so theyre going to make the students do it a certain way.

Haycocks said a fourth-year elective is in the works that would give students the opportunity to learn at a month-long boot camp to become an autopsy technician.

If you want to practice cutting human tissue without any of the rules of surgery, its hard to beat someone who died the day before, Haycocks said.

Cosgrove said it might take a student in a traditional lab an hour of dissection to view a particular nerve and what path it takes.

At UNLV, students will be able to go through several virtual anatomy stations that have specific learning objectives with problems for them to solve.

At the end of the two hours, you emerge from that experience with a wealth of information, she said.

Human body – Wikipedia, the free encyclopedia

"Physiologies" redirects here. For other uses, see Physiology.

The human body includes the entire structure of a human being and comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. Every part of the body is composed of various types of cells, the fundamental unit of life.[1]

At maturity, the estimated average number of cells in the body is given as 37.2 trillion. This number is stated to be of partial data and to be used as a starting point for further calculations. The number given is arrived at by totalling the cell numbers of all the organs of the body and cell types.[2] The composition of the human body is made up of a number of certain elements including carbon, calcium and phosphorus.

The study of the human body involves anatomy and physiology. The human body can show anatomical non-pathological anomalies known as variations which need to be able to be recognised. Physiology focuses on the systems and their organs of the human body and their functions. Many systems and mechanisms interact in order to maintain homeostasis.

Skeletal structure frames the overall shape of the body and does not alter much over a lifetime. General body shape (and female body shape) is influenced by the distribution of muscle and fat tissue and is also affected by various hormones. The average height of an adult male human (in developed countries) is about 1.71.8m (5'7" to 5'11") and the adult female is about 1.61.7m (5'2" to 5'7"). Height is largely determined by genes and diet. Body type and composition are influenced by factors such as genetics, diet, and exercise.

The human body has several body cavities the largest of which is the abdominopelvic cavity. These cavities house the various body organs including the spinal cord which also accommodates the production and flow of cerebrospinal fluid in the ventricular system of the brain.

Many other smaller cavities exist throughout the body called sinuses, which have varied functions. Sinuses in general usage refers to the paranasal sinuses which are involved in the condition sinusitis. The paranasal sinuses are four pairs of vital air-cavities in the cranial bones. These air-filled spaces are paired between the eyes, above the eyes, deeper behind the eyes and around the nasal cavity.

The average adult body contains between 5 and 5 litres of blood and approximately 10 litres of interstitial fluid.

The composition of the human body can be referred to in terms of its water content, elements content, tissue types or material types. The adult human body contains approximately 60% water, and so makes up a significant proportion of the body, both in terms of weight and volume. Water content can vary from a high 75% in a newborn infant to a lower 45% in an obese person. (These figures are necessarily statistical averages).

The vast majority of cells in the human body are not human at all; rather they are of bacteria, archaea, and methanogens such as Methanobrevibacter smithii. The largest proportion of these form the gut flora. The whole population of microbiota include microorganisms of the skin and other body parts and this altogether is termed as the human microbiome.

Contemporary Examples

Have a look here to understand the anatomy of a human joint.

It may sound like a lame excuse, but the authors say men are wired to view women's anatomy as objects.

If he made reference to the lower part of the anatomy, take away 10.

The exceptions: Philip Roth, who on occasion (and in long stretches of The anatomy Lesson) makes my stomach hurt.

My mother was an anatomy professor, so I grew up among bones on wires, organs in jars, and dissected bodies on marble-top tables.

Historical Examples

Psychology is therefore of equal importance with anatomy and acoustics as an element of Vocal Science.

Its use has practically been superseded by the study of anatomy.

Nobody e'd have blamed you any if you'd aimed at a vital section of his anatomy; but you let him off with little more'n a scratch.

The anatomy of a banked-in 3-pointer | LU Sports | newsadvance.com – Lynchburg News and Advance

Posted on by

A.C. Reid is making a habit of banking in 3-point shots with the outcome of Libertys most recent games hanging in the balance.

He banked in a 3 from the left wing as time expired to lift the Flames to a dramatic victory over Radford one week ago at the Vines Center. The junior guard needed the backboard again, this time Thursday night against Gardner-Webb at Paul Porter Arena, to force a second overtime and cap the Flames remarkable comeback win against the Runnin Bulldogs.

What has led to Reid having the confidence to make those shots? The 6-foot-5 guard has never lacked the confidence to take shots since he arrived on campus, but he has become better at shooting off the dribble and with bigger players contesting his shot.

Those two aspects have greatly assisted Reid in getting the shots up quickly and accurately, even though hed prefer his shots to swish through the net instead of banking in off the backboard.

I think its actually kind of difficult to go from that far and try to bank a shot in, Reid said. Ive been blessed these past two games to hit both of those shots.

Reids transformation has steadily taken place this season. His first two seasons were highlighted by his ability to make multiple 3-pointers in a row, but also to be easily pushed off the 3-point line and not get a shot off if he didnt get a clean look to catch and shoot.

Former Liberty basketball player Alex McLean joined the coaching staff as a graduate assistant this season and the players have credited his work with them on improving all facets on the offensive end.

He has particularly worked with Reid and fellow junior guard Ryan Kemrite during drills about two hours before each game on dribbling and shooting, catching and shooting and finishing their shots through contact.

Once that is completed, McLean and Reid begin shooting from midcourt in a challenge to see who can make the most attempts.

Alex does a great job with us and even the coaching staff does a great job with us of just getting a lot of game shots, Reid said. Coach [Ritchie] McKay said it in film the other day, If A.C.s going to be taking those deep shots, then yall need to be practicing that with him in his individual work. I think its just getting those constant reps that will give me the confidence just to take those deep shots during the game.

Reid missed his first five 3-point attempts against Radford before connecting on the banked-in attempt. He caught the inbounds pass from Georgie Pacheco-Ortiz, dribbled to his left and shot from about 24 feet over the outstretched arms of Radford 6-foot-8 center Randy Phillips.

Reid made his first two 3-pointers against Gardner-Webb, but missed five straight long-range attempts before he connected from 30 feet with 1.5 seconds remaining in the first overtime.

Reids shot came in a disjointed sequence as the Flames quickly attempted to get an open look. Pacheco-Ortiz handed the ball off to Reid, who took one dribble in and unleashed his shot from the right wing as GWU 6-foot-6 forward DJ Laster reached out his arm to contest.

I think when youre a confident shooter, youre a confident shooter and he is that, McKay said. He walks on the floor thinking hes going to make the shot. The fact that hes hit a couple of banks probably is attributed more to his nature and his fearlessness than his confidence. He thinks hes going to have a chance to make it.

McKay said Reid has earned the trust from the coaching staff through his leadership and overall IQ. That is a stark contrast to last season when McKay said he was really frustrated with him and Im not sure he liked me so much. I wasnt having any fun coaching him.

But that has changed with Reid being one of the first players off the bench and one of the five who is on the floor in the final minutes. McKay said Reid makes the offense better when hes on the court, and that comes from Reid having the green light to shoot it from any point as the shot clock is winding down.

I dont think I ever lack confidence in my shot. I feel like every shot I take is going in, Reid said. I think that just comes from the reps that Ive taken and the reps Ive completed over the last few years. Im going to continue to take shots because my coaching staff has empowered me to do so.
