yes
The coronoid fossa is located on the anterior side of the humerus, which is the side facing towards the front of the body.
No, the coronoid fossa is on the lateral and anterior aspect of the humerus. It receives the coronoid process of the ulna during flexion of the elbow.
Olecranon fossa receives when extended Coronoid fossa receives it when flexed
The depression in the scapula can be either one of four different structures; the supraspinatus fossa, the infraspinatus fossa, the subscapular fossa, or the glenoid fossa. The problem is that none of these articulate with the ulna. The bone you are probably looking for is the humerus, and it articulates with the last one I mentioned, the glenoid 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.
The fossa that articulates with the humerus is called the glenoid fossa, located on the scapula bone. This fossa forms the shoulder joint, known as the glenohumeral joint, which allows for a wide range of motion of the arm.
The brachialis muscle originates on the distal anterior humerus and insert at the coronoid process. The function of the brachialis is flexion at the elbow.
olecranon fossa
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.
The olecranon fossa of the humerus articulates with the olecranon process of the ulna when the elbow is extended. This forms the back part of the elbow joint.
the ulna fits into the olacranon fossa, specifically the olecranon process.
The glenoid fossa of the scapula articulates with the head of the humerus, forming the shoulder joint. It is a shallow, cup-shaped socket that allows for a wide range of motion in the shoulder joint.
