Humerus

unla. When it contracts it causes flexion. It's located close to the endangerment site the antecubital. Triceps Brachii - It's attachments are the Olecranon process, posterior humerus shaft, and infraglenoid tuberical. When it contracts it causes extention. Anconeus - It's attachments are the lateral epicondyle of humerus, olecranon process of ulna, and ulna blade. When it contracts

A. dens. B. spinous process. C. vertebral foramen. D. transverse process. 44. Going from proximal to distal, the bones of the upper extremity would be: A. metacarpals, carpals, ulna, and humerus. B. carpals, metacarpals, ulna, and humerus. C. humerus, radius, metacarpals, and carpals. D. humerus, radius, carpals, and metacarpals. 45. Going from proximal to distal, the bones of the lower extremity would be: A. femur, tibia, carpals, and metacarpals. B. metacarpals, tarsals, femur

tissue that makes the socket into more of a bowl-like shape. The labrum transforms the hard, angled surface of the glenoid into a deeper socket that molds to fit the head of the humerus. When the head of the humerus doesn't fit into the socket, this is when one will experience problems. The rotator cuff connects the humerus to

Identify the major surface muscles located in the body. Where are the orgins and insertions of these muscles? List the intended actions as well as an exercise or movement for each. A minimum of fifteen muscles is required. The major muscle groups consist of the upper body, Rotator cuff muscle, Upper arm, Quadriceps, Hamstring group, Lower leg and Midsection. The Upper Body consists of the Trapezious muscle which Orgin is located near the base of skull, occipital protuberance and posterior ligaments

Determining the stature of an individual is a very mathematical process. Height correlates with long bone length (Alcantara) so bioarchaeologists have devised multiple formulas that help estimate the stature of an individual within 5 centimeters of the actual height ("Forensic Anthropology"). Before a bioarchaeologist can use the formula, he or she must measure the length of the long bones. The osteometric board is used to determine this. The long bone is placed on the board with one side touching

shoulder is loose in the socket. This often happens in baseball pitchers, swimmers, and other throwing athletes. Shoulder instability can be classified into two different types, dislocations and subluxations. Dislocations happen when the head of the humerus completely pops out of the socket. The first few times this happens, it is usually with significant trauma although some people can have these without any injury at all. After that, it can get easier and easier for the joint to dislocate. Most shoulder

individual morphology and physiology. A standard measurement protocol for bones of particular regions of the skeleton was established with emphasis on length versus width ratio as well as it’s overall size relative to its more complex features, i.e. humerus length versus hand length. Materials and Methods: Materials for this laboratory included Microsoft excel to compile data, a pen and paper to record data, a 15cm ruler, string, a caliper, and a two meter ruler. Since bones often times vary in

Long Bones The femur, ulna and radius, tibia and fibula, humerus and phalanges (bones of the fingers) are all long bones. The periosteum is the outer layer of the long bone that consists of three main parts: • Epiphysis: consists of compact (cortical) bone on the outer layer and cancellous (spongy) bone located

commonly called the triceps muscle, tri meaning three. The long head starts at the inferior rim of the glenoid fossa of the scapula and goes between the teres minor and major. The lateral head attaches to the lateral side on the posterior surface of the humerus, just below the greater tubercle. The medial head of the triceps lies deep to the long and lateral heads. It is attached on the posterior surface below the lateral head. The body of the triceps are formed when all three heads come together (Lippert

is the anterior border and upper surface of the lateral third of the clavicle its insertion is the deltoid tuberosity of humerus. The pectoralis major is also an agonist in the acceleration part of the throw its origin is the clavicle, the sternumand upper ribs, and the tendon of the external oblique muscle the insertion is the lateral lip of the bicipital groove of the humerus. The triceps brachii is an agonist in the acceleration part of the throw and an antagonist when the ball is being drawn back
