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.
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.
Which joint do the humerus and ulna meet?
Elbow joint.
What articulate with the ulna and scapula?
This is called as elbow joint. It is a synovial type of joint. It is actually a joint between humerus and ulna mainly. The radius takes part in the joint passively. This is hinge variety of joint.
What is the insertion of the extensor carpi ulnaris muscle?
Medial epicondyle of humerus and ulna <3
Name the depression on the ulna into which the humerus inserts?
The depression on the ulna into which the humerus inserts is called the trochlear notch. This forms the hinge joint known as the elbow joint.
What is the name of the depression where the ulna meets the humerus anteriorly?
Trochlea
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?
the radius and ulna
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)
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.
Which joint do the humerus and ulna meet?
Elbow joint.
