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 is the depression on the ulna into which the humerus inserts?
olecranon fossa
What is the proximal attachment of the infraspinatus?
The proximal attachment of the infraspinatus muscle is primarily located on the infraspinous fossa of the scapula. It originates from the posterior surface of the scapula, below the spine of the scapula, and spans laterally to attach to the greater tubercle of the humerus. This positioning allows it to play a crucial role in shoulder stabilization and external rotation of the arm.
Anterior depression superior to the trochlea that receives part of the ulna whenthe forearm is flexed?
Olecranon fossa receives when extended Coronoid fossa receives it when flexed
What region resembles the anterior cubital fossa region the most?
The popliteal fossa region on the posterior side of the knee resembles the anterior cubital fossa region in terms of being a shallow depression with important structures passing through it, such as blood vessels and nerves. Both regions also contain lymph nodes and have significance for clinical procedures.
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.

Its structure is crucial for the proper functioning of the elbow joint.
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.
The coronoid process articulates with what depression on the distal end of the humerus?
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.
Where is the intercondylar fossa located?
between the condyles on the distal end of the femur, on its posterior aspect.
Is the coronoid fossa on the lateral and posterior side of the humerus?
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.
Where is the olecranon fossa located?
The olecranon fossa is located on the posterior aspect of the humerus bone in the elbow joint. It is a depression that accommodates the olecranon process of the ulna when the elbow is fully extended.
Anatomical position humerus to scapula?
The humerus articulates with the scapula at the glenoid fossa to form the shoulder joint. Specifically, the head of the humerus sits in the shallow, concave glenoid cavity of the scapula. This ball-and-socket joint allows for a wide range of motion in the shoulder.
Does the humerus has a coronoid fossa?
yes
The coronoid fossa is on what side of the humerus?
The coronoid fossa is located on the anterior side of the humerus, which is the side facing towards the front of the body.
What is the name of the fossa that articulates with the humerus?
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.
What is meaning of 'the posterior fossa is unremarkable'?
When a radiologist says the posterior fossa is unremarkable it means that everything looks normal. Posterior means back, fossa is an anatomical pit of the skull, and unremarkable means nothing stands out as being different.
What is the depression on the ulna into which the humerus inserts?
olecranon fossa
