POSTSCAPULARIS Meaning and
Definition
-
The term "postscapularis" refers to a specific muscle located in the anatomical region of the scapula, or shoulder blade. It is a relatively small muscle that is primarily found in certain mammalian species, particularly in the order of Artiodactyla, which includes cloven-hoofed animals like cows, pigs, and deer.
The postscapularis muscle is situated posteriorly or towards the back of the scapula. It originates from the lateral or outer border of the scapula, specifically from the area between the medial and lateral angle of the bone. From there, it extends medially and attaches to the humerus bone, specifically to the medial or inner side of the bone's shaft.
The main function of the postscapularis muscle is to facilitate movement and stability of the shoulder joint. It assists in the inward rotation, adduction, and elevation of the humerus bone. Additionally, it also contributes to maintaining the overall integrity and support of the shoulder region.
While the postscapularis muscle is relatively less known compared to other larger muscles of the shoulder, its role in shoulder movement and stability should not be undermined. Understanding the anatomy and function of the postscapularis muscle is crucial in comprehending the intricate workings of the shoulder joint and its associated musculature.
