The torso or trunk is an anatomical term for the central part, or the core, of the body of many animals (including human beings), ... Major muscle groups
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.
Functional movements are highly dependent on this part of the body, and lack of core muscular development can result in a predisposition to injury. [1] The major muscles of the core reside in the area of the belly and the mid- and lower back (not the shoulders), and peripherally include [clarification needed] the hips, the shoulders and the neck.
The body's core region is sometimes referred to as the torso or the trunk, although there are some differences in the muscles identified as constituting them. The major muscles involved in core stability include the pelvic floor muscles, transversus abdominis , multifidus , internal and external obliques , rectus abdominis , erector spinae ...
The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [1] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle) can be
Beneath the pectoralis major is the pectoralis minor muscle. The pectoralis major arises from parts of the clavicle and sternum, costal cartilages of the true ribs, and the aponeurosis of the abdominal external oblique muscle; it inserts onto the lateral lip of the bicipital groove.
Gross anatomy has become a key part of visual arts. Basic concepts of how muscles and bones function and deform with movement is key to drawing, painting or animating a human figure. Many books such as Human Anatomy for Artists: The Elements of Form, are written as a guide to drawing the human body anatomically correctly. [4]
The muscle's size and position make it uniquely suited for controlling trunk position during rapid movements and stabilizing the trunk against flexion. While traditionally associated with maintaining erect posture, evidence suggests its enlargement was more likely selected for its role in running capability and trunk stabilization during ...
