Pectoralis minor muscle (/ ˌ p ɛ k t ə ˈ r æ l ɪ s ˈ m aɪ n ər /) is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major in the human body. It arises from ribs III-V; it inserts onto the coracoid process of the scapula. It is innervated by the medial pectoral nerve.
Deep muscles of the chest, including pectoralis minor, serratus anterior, and subclavius (Gray 1918) Pectoralis major is a thick, fan-shaped or triangular convergent muscle, which makes up the bulk of the chest muscle. It lies under the breast. It serves to flex, extend, and rotate the humerus, the long bone of the upper arm. Pectoralis minor ...
Muscles that attach to and depress the scapulae include the lower trapezius muscle and the pectoralis minor. The pec minor also works in conjunction with the rhomboid muscle and levator scapulae to perform downward rotation of the scapulae.
The five muscles that comprise the function of the shoulder girdle are the trapezius muscle (upper, middle, and lower), levator scapulae muscle, rhomboid muscles (major and minor), serratus anterior muscle, and pectoralis minor muscle. [3]
Apart from the above neck muscles, the following muscles have also been observed contributing to respiration: serratus anterior, pectoralis major and pectoralis minor, trapezius, latissimus dorsi, erector spinae, iliocostalis, quadratus lumborum, serratus posterior superior, serratus posterior inferior, levatores costarum, transversus thoracis ...
The push-up requires the work of many muscle groups, with one of the primary muscle groups being the chest muscles, the pectoralis major and the minor. [7] These are the two large chest muscles and the main pushing muscle group of the upper body. When pushing and lowering the body during a push-up, the pectoralis major is doing most of the work.
A conventional bench press uses the pectoralis major, front deltoids, [6] and triceps brachii to horizontally adduct the shoulder. While flat bench pressing, the pectoralis major and pectoralis minor muscles are activated. [7] [8] The exercise also uses the triceps and anconeus to extend the elbows. [6]
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
