The trochlea articulated with the trochlear notch and coronoid. The elbow is a hinge joint with a rotatory component where the trochlea forms the convex, proximal surface which articulates with the concave, distal surface on the ulna, the trochlear notch. While the trochlea together with its associated fossae almost covers a 360° angle, the ...
The trochlear nucleus is located in the midbrain, at an intercollicular level between the superior colliculus and inferior colliculus. [3] As with all motor nuclei of cranial nerves, it is located near the midline (i.e. in the medial midbrain). [2]
The Cavernous Sinus. Each trochlear nerve originates from a trochlear nucleus in the medial midbrain.From their respective nuclei, the two trochlear nerves then travel dorsal-ward through the substance of the midbrain surrounded by the periaqueductal gray, crossing over (decussating) within the midbrain before emerging from the dorsal midbrain [3] [4] just inferior to the inferior colliculus.

The humerus (/ ˈ h juː m ər ə s /; pl.: humeri) is a long bone in the arm that runs from the shoulder to the elbow.It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections.
The flare was first detected in February 2024 with a newer radio telescope called the Canadian Hydrogen Intensity Mapping Experiment (CHIME.) ... The location of the fast radio burst, indicated by ...
A new critter is creeping into the United States' waters. The invasive Australian redclaw crayfish was recently spotted in Southern Texas, roughly 8,000 miles away from its home. The freshwater ...
The trochlear notch (/ ˈ t r ɒ k l ɪər /), [1] also known as semilunar notch and greater sigmoid cavity, is a large depression in the upper extremity of the ulna that fits the trochlea of the humerus (the bone directly above the ulna in the arm) as part of the elbow joint. It is formed by the olecranon and the coronoid process.
