MUSCULUS PECTORALIS Meaning and
Definition
-
Musculus pectoralis, commonly known as the pectoralis muscle or pectoral muscle, refers to a pair of large muscles located on the anterior (front) part of the chest wall in humans and many other vertebrates. The term "musculus pectoralis" is derived from the Latin words "musculus" meaning muscle, and "pectus" meaning chest. Comprising the pectoralis major and pectoralis minor muscles, they play a crucial role in upper body movement and stabilization.
The pectoralis major is the larger and more superficial of the two muscles. It originates from the clavicle, sternum, and costal cartilages and inserts into the humerus (upper arm bone). It is responsible for the movements of the shoulder joint, such as flexion, adduction, and medial rotation. It also contributes to the forward motion of the arm, as in throwing or pushing.
On the other hand, the pectoralis minor is a smaller, triangular-shaped muscle beneath the pectoralis major. It originates from the third to the fifth ribs and attaches to the coracoid process of the scapula (shoulder blade). Its primary function is to stabilize and depress the scapula, allowing for proper movement and stability of the shoulder girdle.
Both the pectoralis major and pectoralis minor muscles are important in everyday activities, ranging from lifting objects and performing upper body exercises to maintaining proper posture. They are also involved in various sports and physical activities that require upper body strength and coordination.
