Muscle is a soft tissue, one of the four basic types of animal tissue. Muscle tissue gives skeletal muscles the ability to contract. Muscle is formed during embryonic development, in a process known as myogenesis. Muscle tissue contains special contractile proteins called actin and myosin which interact to cause movement.
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
A muscle slip is a slip of muscle that can either be an anatomical variant, [2] or a branching of a muscle as in rib connections of the serratus anterior muscle. Smooth muscle [ edit ]
It's recommended that adults do muscle-strengthening activities at least two days per week, targeting all major muscle groups. That means legs, hips, back, abdomen, chest, shoulders and arms.
In ordinary parlance, muscular "strength" usually refers to the ability to exert a force on an external object—for example, lifting a weight. By this definition, the masseter or jaw muscle is the strongest. The 1992 Guinness Book of Records records the achievement of a bite strength of 4,337 N (975 lb f) for 2 seconds. What distinguishes the ...
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.
The goal is to make adequate tears in the muscle fibers through strength training and consume enough nutrients to repair those fibers, allowing muscles to rebuild bigger and stronger. Cutting, on ...
A muscle cell, also known as a myocyte, is a mature contractile cell in the muscle of an animal. [1] In humans and other vertebrates there are three types: ...
