The triceps, or triceps brachii (Latin for "three-headed muscle of the arm"), ... The long head arises from the infraglenoid tubercle of the scapula.
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.
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 triceps (also known as the triceps brachii) is the muscle behind the arm, opposite of the bicep — and they get their name due to being made up of three different muscles. In order to tone ...
The infraspinatus and teres minor insert on the greater tubercle, and work to laterally, or externally, rotate the humerus. In contrast, the subscapularis muscle inserts onto the lesser tubercle and works to medially, or internally, rotate the humerus. The biceps brachii, brachialis, and brachioradialis (which attaches distally) act to flex the ...
The triceps muscle, scientifically known as the triceps brachii, sits along the backside of your upper arm. While it's one muscle, there are three sections: the long head, lateral head, and medial ...
The lateral intermuscular septum extends from the lower part of the crest of the greater tubercle of the humerus, along the lateral supracondylar ridge, to the lateral epicondyle; it is blended with the tendon of the deltoid muscle, gives attachment to the triceps brachii behind, and to the brachialis, brachioradialis, and extensor carpi radialis longus muscles in front.
