T- for elbow extension it is olecranon

T/F Normal bony limitation of elbow flexion is limited by the coranoid process fitting into the coranoid fossa.

T

T/F Bony stability of the elbow in full extension is enhanced by the olecranon process fitting into the olecranon fossa.

F- replace less with more

T/F Lateral epicondylitis is a condition that occurs less commonly than medial epicondylitis.

T

T/F Motion of the elbow primarily involves movement between articular surfaces of the humerus and ulna.

F- replace flexion with extension

T/F Movement at the elbow by the forearm away from the shoulder is accurately described by the term "flexion."

T

T/F Positioning the forearm in pronation reduces the effectiveness of the biceps brachialis in flexing the elbow.

T

T/F The distal attachments of the radioulnar joint muscles are located on the radius.

T

T/F The olecranon process is located on the medial aspect of the ulna.

T ( long head)

T/F The origin of the biceps brachii muscle includes the supraglenoid tubercle above the superior lip of the glenoid fossa.

T C6, C7

T/F The pronator teres is innervated by the median nerve.

T

T/F The radial collateral ligament provides lateral stability to the elbow and is rarely injured.

F- replace capitulum with radial notch

T/F The radial head sits inside of the capitulum and is held in place by the annular ligament.

T

T/F The ulna is much larger proximally than the radius.

T

T/F When performing a pushup the biceps brachii is considered to be an antagonist musc

T

T/F When the arm is held in the anatomical position the radial tuberosity is in close proximity to lateral side of the ulna.

F- swap ulna & radius

T/F While in the anatomical position the radius is medial with respect to the ulna.

T

T/F The insertion of the brachialis muscle is the coracoid process of the ulna.
