Trochlear notch
The radius
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.
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).
The superior oblique muscle turns the eye inferiorly and medially. It is innervated by the trochlear nerve.

Trochlear notch
If you're referring to the trochlear nerve - it's located in the eyeball.
The trochlea of the humerus is where your ulna joins with your humerus to create your 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.
The Trochlear Nerve
The radius
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.
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.
