This region contains four muscles that provide movements to the upper limbs or ribs. Deep muscles of the chest, including pectoralis minor, serratus anterior, and subclavius (Gray 1918)
This is a compound exercise that also involves the triceps and the front deltoids, also recruits the upper and lower back muscles, and traps. The bench press is the king of all upper body exercises and is one of the most popular chest exercises in the world. It is the final exercise in 'The big 3'.
The pectoralis major (from Latin pectus 'breast') is a thick, fan-shaped or triangular convergent muscle of the human chest. It makes up the bulk of the chest muscles and lies under the breast. Beneath the pectoralis major is the pectoralis minor muscle.
The bony skeletal part of the thoracic wall is the rib cage, and the rest is made up of muscle, skin, and fasciae.. The chest wall has 10 layers, namely (from superficial to deep) skin (epidermis and dermis), superficial fascia, deep fascia and the invested extrinsic muscles (from the upper limbs), intrinsic muscles associated with the ribs (three layers of intercostal muscles), endothoracic ...
The intercostal muscles comprise many different groups of muscles that run between the ribs, and help form and move the chest wall.The intercostal muscles are mainly involved in the mechanical aspect of breathing by helping expand and shrink the size of the chest cavity.
The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum .
An X-ray of a human chest area, with some structures labeled. The contents of the thorax include the heart and lungs (and the thymus gland); the major and minor pectoral muscles, trapezius muscles, and neck muscle; and internal structures such as the diaphragm, the esophagus, the trachea, and a part of the sternum known as the xiphoid process.
The bench press or chest press is a weight training exercise where a person presses a weight upwards while lying horizontally on a weight training bench. The bench press is a compound movement, with the primary muscles involved being the pectoralis major, the anterior deltoids, and the triceps brachii. Other muscles located in the back, legs ...
