How many attachments does the triceps Brachii have?

It consists of 3 parts: the medial, lateral, and long head. It is the muscle principally responsible for extension of the elbow joint (straightening of the arm).

Insertion Olecranon process of ulna
Artery Deep brachial artery, posterior circumflex humeral artery (long head only)
Nerve Radial nerve

Where does the triceps brachii long head attach?

Triceps brachii muscle

Origins Long head – infraglenoid tubercle of the scapula Medial head – posterior surface of the humerus (inferior to radial groove) Lateral head – posterior surface of the humerus (superior to radial groove)
Insertion Olecranon of ulna and fascia of forearm

What are the 3 heads of the triceps?

What nerve controls the triceps?

The triceps brachii muscle is the sole muscle occupying the posterior compartment of the upper arm and is innervated by the radial nerve (C6–C8). It is composed of three tendinous origins: the long, lateral, and medial heads. The long head originates at the infraglenoid tuberosity of the scapula.
