Tricep origin and insertion. Even though the triceps have three different origins it only has one insertion. The heads converge to a single tendon and eventually inserts into the posterior Olecranon Process of the ulna. Triceps brachii origin and insertion The triceps brachii long head originates from the infraglenoid tubercle of the scapula which is the lateral part.
It represents the only constituent of the posterior muscle group of the arm spanning almost the entire length of the humerus. The triceps brachii muscle consists of a long medial and lateral head that originate from their respective attachments on the humerus and scapula and insert via a common tendon on the ulna. What is the origin of the triceps Brachii medial head.
The medial head of the Triceps brachii arises from inferior two thirds of humerus to insert along with the other two heads of the triceps on the olecranon of the ulna. The long head which originates from the infraglenoid tubercle which is just below the glenoid cavity of the scapula. All three heads of the triceps brachii converge together and insert onto the.
Origin and insertion The triceps brachii muscle has three heads each of which have their own origin. The long head arises from the infraglenoid tubercle of scapula which is a rough area at the inferior margin of the glenoid fossa.

While both its origin tendons are covered by the deltoid its insertion tendon can be easily seen and palpated at the crook of the arm. The space between the biceps and triceps forms two grooves medial and lateral bicipital grooves. Within the medial bicipital groove course the brachial artery and both the ulnar and median nerves.
The Triceps brachii gets its name with tri referring to three muscle heads or points of origin with Brachii referring to the arm. Medial head green Origin edit edit source. Accordingly what is the origin and insertion of the tricep.

The main difference between origin and insertion is that origin is the attachment point of skeletal muscles which does not move during contraction whereas insertion is the attachment point that moves during contraction. Furthermore the origin of the skeletal muscles is more proximal while insertion is more distal when considering the location of the attachment points.
