LACERTUS MEDIUS Meaning and
Definition
-
Lacertus medius, also known as the "middle arm," is a term used in anatomy to refer to a specific anatomical structure located in the upper limb of mammals, including humans. Specifically, it is a muscle found in the anterior compartment of the arm.
The lacertus medius muscle originates from the humerus, more precisely from the medial portion of the brachialis muscle and the intermuscular septum. It then extends inferiorly, crossing the anterior aspect of the forearm and inserts onto the ulna.
The lacertus medius muscle plays an important role in the movement and stabilization of the forearm and hand. It aids in flexion of the forearm at the elbow joint, which involves bending the forearm toward the upper arm. Additionally, it contributes to the stabilization of the elbow joint during activities that require precise movements of the hand and forearm, such as grasping objects or performing delicate manual tasks.
The lacertus medius muscle, with its anatomical positioning and functions, is a vital component of the upper limb musculature. Understanding the role of this muscle can assist healthcare professionals in diagnosing and treating certain conditions related to the arm, forearm, and hand.
