What is the trochlear notch that articulates with the humerus?

The trochlear notch is a depression on the proximal end of the ulna bone that articulates with the trochlea of the humerus. This forms the hinge joint of the elbow, allowing for flexion and extension of the forearm.


Which part of the body includes the humerus and the ulna?

The humerus and ulna are found in the arms


What three bones make up your arms?

The Humerus (upper arm), Radius (lower arm) and Ulna (Lower arm and elbow)


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 two bones articulate with the distal humerus?

The ulna and the radius articulate with the distal humerus at the elbow joint. The ulna forms the primary articulation, while the head of the radius articulates with a small depression on the side of the ulna known as the radial notch.


What bone sits in the olecranon fossa?

The olecranon fossa is a depression in the humerus bone of the upper arm, and it is specifically designed to accommodate the olecranon process of the ulna bone. The olecranon is a prominent bony projection at the end of the ulna that forms the bony part of the elbow.


What are the bones of forearm?

What is the name of all the bones in your elbow?

The elbow is not in and of itself a bone. It is the joining of the humerus, ulna, and radius-most specifially, the humerus and ulna. The bony point that we think of as the elbow is part of the ulna (one of the forearm bones). It is called the olecranon process. The smaller bumps on the sides are parts of the humerus (upper arm bone). They are called epicondyles.


What bony landmark of the anterior humerus articulates with the ulna?

To you mean the joint itself? The elbow, AKA the proximal-distal axis of the humerus and ulna, respectively.Or just the distal epiphysis of the humerus (the rounded head of the bone which is farther fromthe arm's point of attachment to the torso)
