The triceps, or triceps brachii (Latin for "three-headed muscle of the arm"), is a large muscle on the back of the upper limb of many vertebrates. It consists of three parts: the medial, lateral, and long head. [ 1 ]
The infraglenoid tubercle is where the long head of the triceps brachii originates. The infraglenoid tubercle is located on the lateral part of the scapula, inferior to (below) the glenoid cavity. The name infraglenoid tubercle refers to its location below the glenoid cavity.
The infraglenoid tubercle is the part of the scapula from which the long head of the triceps brachii muscle originates. The infraglenoid tubercle is a tubercle located on the lateral part of the scapula, inferior to (below) the glenoid cavity. The name infraglenoid tubercle refers to its location below the glenoid cavity.
It is formed by the longitudinal hollow between the biceps and triceps muscles. The pulse of the brachial artery can be felt in the medial bicipital groove. [1] It should be distinguished from the bicipital groove or intertubercular sulcus, which is not a surface anatomy structure. It is the groove where the long head of biceps tendon runs ...
The triceps brachii has a potential to entrap the radial nerve in the triangular interval secondary to hypertrophy. The presence of a fibrous arch in the long head and lateral head further complicates the situation. Repeated forceful extension seen in weight training and sport involving punching may be a precedent to this scenario.
The triangular interval is bounded medially by long head of triceps brachii, laterally by medial border of humerus (some say the lateral head of the triceps), and superiorly by teres major. The radial nerve and profunda brachii artery and vein passes through this space. [3]
The triceps (also known as the triceps brachii) ... The long head runs along the inner side of the upper arm and travels from the scapula to the elbow. The lateral head is on the outer side of the ...
The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb.It innervates the medial and lateral heads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and overlying skin.
