Muscle pectoral gauche

The pectoral region is located on the anterior chest wall. It contains four muscles that exert a force on the upper limb: the pectoralis major, pectoralis minor, serratus anterior and subclavius. In this article, we shall look at the anatomy of the muscles of the pectoral region – their attachments, actions and innervation.

The pectoralis major muscle is a large muscle in the upper chest, fanning across the chest from the shoulder to the breastbone. The two pectoralis major muscles, commonly referred to as the ‘pecs,’…

Pectoralis muscle, any of the muscles that connect the front walls of the chest with the bones of the upper arm and shoulder. There are two such muscles on each side of the sternum (breastbone) in the human body: pectoralis major and pectoralis minor. The pectoralis major, the larger and more superficial, originates at the clavicle (collarbone), the sternum, the ribs, and a tendinous extension …

Pectoral muscles (colloquially referred to as “pecs”) are the muscles that connect the front of the human chest with the bones of the upper arm and shoulder. Deep muscles of the chest, including pectoralis minor, serratus anterior, and subclavius (Gray 1918) Pectoralis major is a thick, fan-shaped muscle, which makes up the bulk of the chest muscle. It lies under the breast. It serves to flex …

The pectoralis major (from Latin pectus ‘breast’) is a thick, fan-shaped muscle, situated at the chest of the human body.It makes up the bulk of the chest muscles and lies under the breast.Beneath the pectoralis major is the pectoralis minor, a thin, triangular muscle.The pectoralis major’s primary functions are flexion, adduction, and internal rotation of the humerus.

Muscles That Position the Pectoral Girdle Muscles that position the pectoral girdle are located either on the anterior thorax or on the posterior thorax ([link] and [link]). The anterior muscles include the subclavius, pectoralis minor, and serratus anterior. The posterior muscles include the trapezius, rhomboid major, and rhomboid minor.

The pectoralis major is the most important thick and fan-shaped muscle that is situated at the anterior part of the chest in a male human body. In females this important muscle is spread underneath the breast. A well-developed pectoralis major is very much evident in men who exercise regularly.

Pectoral muscles also aid in breathing by moving the ribcage. They are also known as pecs. People who want to enhance their pectoral muscles may start lifting weights. Pecs start in the sternum and attach to the joints in the shoulder and along the ribcage.
