Origin
The muscular branch to the anconeus muscle arises from the radial nerve (C6—C8 cervical spinal segments).
Course
The radial nerve passes through the lower triangular space to descend inside the spiral radial groove against the humerus, between the lateral and medial heads of triceps muscle. Two muscular branches are given off in the groove to the lateral and medial heads of triceps muscle. The second branch of the radial nerve to the medial head of the triceps brachii also innervates the anconeus muscle. This is the more distal of the two branches that innervates the medial head of the triceps brachii, after which it passes through the medial head in the posterior compartment of the arm and continues distally to provide innervation for the anconeus muscle.
Branches
There are no named branches.
Supplied Structures
The muscular branch of the radial nerve to anconeus provides motor innervation to the anconeus muscle.
