The posterior surface of the humerus serves as an attachment site for various muscles and ligaments, contributing to the shoulder and arm's movement and stability. It features the radial groove, which houses the radial nerve and the deep brachial artery, allowing for the passage of neurovascular structures. Additionally, the posterior surface plays a role in the overall anatomy of the humerus, aiding in the alignment and articulation with the forearm bones at the elbow joint.
What else can I help you with?
Select the correct origins of the triceps brachii:?
Infraglenoid tubercule of scapula, posterior surface of humerus, superior lateral margin of humerus
Fossa on distal posterior surface 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.
Which muscle covers most of the posterior of the humerus?
triceps
What is the posterior depression on the distal humerus?
The posterior depression on the distal humerus is known as the olecranon fossa. It is a deep, triangular cavity located on the posterior aspect of the humerus, just above the elbow joint. This fossa accommodates the olecranon process of the ulna during elbow extension, allowing for smooth movement and articulation between the humerus and ulna. Its structure is crucial for the proper functioning of the elbow joint.
What muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus?
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.
Teres major antagonist?
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.
Bone that contains the olecranon fossa?
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.
anterior and posterior relation of both the kidny?
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.
Extensors of the wrist and hand a. are located within the posterior compartment of the forearm b. attach to the lateral epicondyle of the humerus c. pass through the carpal tunnel d. a and b?
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.
Which large bone has a subcutaneous surface?
humerus
What is the origin of the tricep?
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?
What is the chew surface of the posterior teeth?
This is the Occlusal surface
