Upper Extremities (Humerus)

Captiulum

Is the smooth, convex projection found on the inferolateral aspect of the condyle of the humerus, it is the lateral of the two articular projections located at the distal end of the condyle of the humerus, the other being the trochlea of the humerus. These two articular projections are separated from each other by a shallow groove

\
It articulates with the head of the radius, forming the humeroradial joint, thus contributing to the formation of the elbow joint.

Coronoid fossa

is the small depression found superior to the trochlea of the humerus. it is the medial of the two fossae located on the anterior aspect of the condyle of the humerus, the other being the radial fossa.

\
It accommodates the coronoid process of ulna during elbow flexion

deltoid tuberosity

is the rough, triangular prominence found at the middle third of the anterolateral surface of the humerus

\
it provides and insertion site for the deltoid muscle

olecranon fossa

is the large, deep depression found along the posterior aspect of the condyle of humerus. it is formed by the concave posteromedial surface of the greater trochanter

it accommodates the olecranon of ulna during elbow extension

surgical neck

is the short, constricted part found at the proximal end of the body of the humerus. it is located distal to the greater and lesser tubercle.

\
is the weak area of the humerus and is therefore a common site for humeral fractures.

trochlea

is the smooth, pulley-shaped projection found on the inferomedial aspect of the condyle of the humerus. it is the medial of the two articular projections locates at the distal end of the condyle of the humerus, the other being the capitulum. These two articular projections are separated from each other by a shallow groove.

\
it articulates with the trochlear notch of ulna, forming the humeroulnar joint, contributing to the formation of the elbow joint.
