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.
Where does the trochlea lie in comparison to the capitulum?
The trochlea lies on the medial side of the humerus, while the capitulum is located on the lateral side of the distal humerus. These two structures, along with the trochlear notch of the ulna, form the hinge joint of the elbow.
Which bones articulates with the ulna?
At the distal end: the carpels in the hand at the head of the ulna and the radius at the ulna notch of radius. At the proximal end: the trochlea of the humerus at the trochlear notch and coronoid process of the ulna and the head of the radius at the radial notch of the ulna.
What is the vertebral level of the jugular notch?
The jugular notch, or suprasternal notch, is in line with/at the level of the intervertebral junction between the second and third thoracic vertebra (between T2 & T3).
Where is the ulnar notch located?
The ulnar notch is located on the distal end of the radius bone, on the side where the ulna bone is situated. It forms part of the wrist joint, allowing for articulation with the ulna bone and enabling proper movement of the wrist.
What bone articulates with trochlear notch?
elbow
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 does trochlear mean in human biology?
If you're referring to the trochlear nerve - it's located in the eyeball.
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 two features make up the hinge at the elbow?
One feature that makes up the hinge at the elbow is the trochlea of humerus. The other feature is the trochlear notch of the ulna.
Where does the trochlea lie in comparison to the capitulum?
The trochlea lies on the medial side of the humerus, while the capitulum is located on the lateral side of the distal humerus. These two structures, along with the trochlear notch of the ulna, form the hinge joint of the elbow.
What type of joint is humeroulnar?
The humeroulnar joint is a hinge joint, allowing for flexion and extension movements of the elbow. It is formed by the articulation between the trochlea of the humerus and the trochlear notch of the ulna.
What is a spool-shaped process on distal end of the humerus that is found medial to the capitulum and articulates with the ulna?
The trochlea is the spool-shaped process of the humerus that articulates with the ulna. The ulna's trochlear notch fits onto the trochlea for stability.
What is the smallest cranial nerve?
The smallest cranial nerve is the trochlear nerve (CN IV). It is responsible for controlling the superior oblique muscle of the eye, which helps with downward and inward eye movement.
Where the sciatic notch is located?
between pelvic bones
What is the name of smallest nerve?
The Trochlear Nerve
What thoracic level manubrial notch is located?
thoracic 4
