Supination

Comparisons of the foot and ankle of Chimpanzees and Homo sapiens sapiens show several distinct changes. These changes developed mainly due to the transition from quadrupedal to bipedal movement and becoming more terrestrial rather than arboreal. When researching different hominids in chronological order, it is clear that each change in our foot morphology occurred at a different time in our evolutionary history, and not all traits are exhibited in extinct lines of Homo and other hominid…

rather prodigious girth. Further cause for ridicule from his puerile classmates at Robert E. Seaman elementary was the fact that his feet were splayed and compressed under the burden they bore, and while one shoe was worn down on its outer edge from supination, the other was slanted opposite from pronation and the result was that Walter Waddles ... well, he waddled. He thought that he had heard them all, and with characteristic aplomb executed peremptory strikes upon himself whenever he…

I Anatomy of the shoulder The shoulder joint, as it is commonly called, is not a single joint but a complex arrangement of bones, ligaments and musculotendinous units that called the shoulder girdle. The primary role of the shoulder girdle is to provide a tremendous range of motion for positioning the upper extremity in space. The shoulder girdle also provides power and support for the upper extremity throughout and at the extremes of the range of motion. (19) The…

individually. While muscles are categorized by different fibers, all 600 or so muscles found in the human body provide the same function, movement. However, this movement is provided by different forces. Flexion, extension, adduction, abduction, rotation, supination, and pronation are all terms that describe the different muscular movements. These terms all describe the upward, downward, inward, and outward movements that humans need to walk, eat, use their hands, elbows, knees and hips. Just…

This case review involved a 19-year-old male football play who is currently a freshman in college. He came into the athletic training room complaining of right wrist pain. This athlete has had pain in this wrist for a couple of mouths and had only every taped the wrist two weeks prior to coming into the athletic training room for his first treatment. Even before coming in, he was able to do every drill or exercise at practice to completion. He only reported feeling pain during practice when he…

Evolution of the Bony Projection on Ailurus fulgens Melanie Brown Dixie State University Author Note: This paper was prepared for Evolution 3010, class instructed by Dr. Curtis Walker Throughout the evolution of the hand, most commonly found in primates, advantages of a thumb have led to the improvement of activities such as gripping and squeezing. Over time, few species developed full capabilities and usage of the thumb. Some species developed slightly while others did not develop it…

DISCUSSIONS Discussion Part One (graded) Setting: Suburban family practice office Part 1: You review the chart before entering the room. The patient is Elizabeth, age 16, with a chief complaint of a left ankle injury. Elizabeth is an Irish dancer and has been seen in the past for other injuries. At the last visit 8 months ago, Elizabeth had a groin pull and was sent to physical therapy (PT) for evaluation and treatment. The PT notes state Elizabeth has lax ligaments and responded well to PT.…

“The human body,” many of us don’t nearly realize what happens throughout the body, and if I’m being honest, neither did I, up until I took Anatomy and Physiology in high school and my freshman year of college. It is truly amazing, how many systems and functions one’s body has; from the smallest of molecules to the largest of organs, all working together to keep the one going. The entire body is made up of cells, all working hard making sure everything is working accordingly. From making swift…

R.W.Barfield (1998) Biomechanics of kicking in soccer. The objective of the study was to examine the effect of angle of approach on kicking accuracy. Accuracy kicking is necessary for successful kicks from penalty mark. The study included 7 male amateurs recreational soccer player aged 26+/- 3years, body mass 74-80 kgs, stature 1.74 +/- 0.06 m, who were right foot dominant. Kicking kicks from penalty mark at 0.6x0.6 target at the full size goal post according to their self selected approach…

split into three major joints including the humeroulnar, humeroradial, and the proximal radioulnar joint. Consisting of a uniaxial hinge joint that helps with forearm rotation. With 2 degrees of freedom allowing flexion to 135 degree, pronation, and supination. These joints mainly rely on ligaments for most of their stability, by the medial and lateral collateral ligaments.(2) Additional stability is presumed by the muscle tendons. The forearm tendons also known as extensors attaching the…
