Elbow Functions

CHAPTER 5 STRUCTURE AND draw OF THE ELBOW AND FOREARM COMPLEX The go on up complex allows movements of pronation and supination motions that expand the palm upward or downward. The fortify consists of two articulations: the proximal and distal radio ulnar mutual. Joints of the cubital joint and fortify complex 1.Humeroulnar joint 2.Humeroradial joint 3.proximal radioulnar joint 4.distal radioulnar joint The four prinks that occupy to the function of the elbow and fortify complex 1.Scapula 2.Distal humerus 3.Ulna 4.Radius Scapula Scapula has troika gaunt features that are measurable to the muscles of the elbow 1.Coracoid ferment-serves as the proximal adherence for the pitiful passman of the biceps 2.Supraglenoid tubercle- serves as the proximal attachment for the spacious head of the biceps 3.Infraglenoid tubercle- marks the proximal attachment for the long head of the triceps Distal Humerus 1.Trochlea- spool make structure locate on the medial incline of the distal humerus that articulates with the ulna to form the humeroulnar joint 2.Coronoid fossa- a teeny-weeny pit located bonny superior to the trochlea that accepts the coronoid process of the ulna when the elbow is encompassingy flexed. 3.

Capitulum- just squint to the trochlea, articulates with the head of the r to form the humeroradial joint 4.Medial epicondyle- the prominate projection of bone on the medial boldness of the distal humerus. This easily obvious prominence serves as the proximal attachment for or so of the radiocarpal joint flexor muscles, the pronator teres, and the confirmatory ligament of the elbow 5.Lateral epicondyle- slight prominent, proximal attachment for most wrist extensor muscles, the supinator muscle, and squint collateral ligament of the elbow. Immediately proximal to some(prenominal) epicondyles are the medial and lateral supracondylar ridges. 6.Olecranon fossa- is the relatively deep, all-encompassing pit, located on the posterior side of the distal humerus. With the elbow fully extended, a portion...If you want to proceed a full essay, auberge it on our website: Ordercustompaper.com
