Infraglenoid tubercule of scapula, posterior surface of humerus, superior lateral margin of humerus
The fossa on the distal posterior surface of the humerus is the olecranon fossa. It is located above the trochlea and accommodates the olecranon process of the ulna when the elbow is extended. It helps to increase the range of motion of the elbow joint.
triceps
The muscle you are referring to is the subscapularis muscle. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. It is responsible for medial rotation of the shoulder joint.
The teres major muscle functions in both adduction and medial rotation of the humerus. The antagonists of this muscle are those which abduct the humerus and rotate it externally. The infraspinatus, posterior deltoid, and teres minor all function as antagonists of the teres major.
The bone that contains the olecranon fossa is the humerus, which is located in the upper arm. The olecranon fossa is a depression on the posterior side of the humerus that accommodates the olecranon process of the ulna when the arm is extended.
The kidneys have their anterior and posterior surfaces. The foremost surface countenances towards the front stomach wall, while the back posterior surfaces confronting the posterior stomach wall. These surfaces are isolated by the edges of the kidney, which are the significant convexity horizontally, and minor concavity medially.
humerus
d. a and b The extensors of the wrist and hand are located within the posterior compartment of the forearm and attach to the lateral epicondyle of the humerus. They do not pass through the carpal tunnel.
This is the Occlusal surface
The long head from infra-glenoid tubercle, the medial convers most of the posterior area of humerus and the lateral from a ridge above the spiral groove. That is for the brachii Or do you mean Surae?
