The ➡️triceps brachii muscle⬅️ is a large muscle in the horse’s upper forelimb. It is composed of three distinct heads: Caput Longum, Caput Mediale, and Caput Laterale.

Each of these muscle heads has a unique placement and function.

Caput Longum:
➡️Location: The Caput Longum is the long head of the triceps brachii and is situated on the caudal aspect (rear part) of the humerus bone.
➡️Function: It is primarily responsible for extending the shoulder joint. This means it plays a key role in moving the forelimb backward, such as during the swing phase of the stride.

Caput Mediale:
➡️Location: The Caput Mediale is the medial head of the triceps brachii, located towards the inner side of the upper forelimb.
➡️Function: This head contributes to the extension of the elbow joint. It is involved in straightening the forearm, which is essential for various activities, including weight-bearing and propulsion.

Caput Laterale:
➡️Location: The Caput Laterale is the lateral head of the triceps brachii, situated on the outer side of the upper forelimb.
➡️Function: Similar to the Caput Mediale, the Caput Laterale is involved in the extension of the elbow joint. It works in conjunction with the other heads to provide strength and coordination during activities like weight-bearing and pushing off the ground.
