The lateral head originates from the back surface of the humerus, just above the radial groove. The long head originates from the infraglenoid tubercle of the scapula. The long head of the triceps brachii originates from the infraglenoid tubercle of the scapula.
Consequently, where are the triceps located on the human body?
The triceps brachii is a major muscle of the upper arm in the human body. The triceps run along the humerus (the main bone of the upper arm) between the shoulder and the elbow. Along with the biceps, it enables extension and retraction of the forearm.
What is the origin of the tricep?
Function. The triceps is an extensor muscle of the elbow joint and an antagonist of the biceps and brachialis muscles. With its origin on the scapula, the long head also acts on the shoulder joint and is also involved in retroversion and adduction of the arm.
How many heads of origin do you think the triceps?
The triceps brachii has three heads (connective immovable muscle) and is the only muscle on the back of the upper arm. It connects the humerus (upper arm bone) and the scapula (shoulder blade) to the ulna (longest of the forearm bones) and is Continue Scrolling To Read More Below
