Answer 4

the point where bone meets muscle that is proximal to the joint

Question 5

what are the origins of the triceps brachii

Answer 5

the scapula (1 attachment)
the humerus (2 attachments)

Question 6

what is the insertion of the triceps brachii

Answer 6

olecranon process of the ulna

Question 7

what movements is the triceps brachii involved in

Answer 7

shoulder - extension - posterior
elbow - extension - posterior
