Skeletal muscle. Skeletal muscle (commonly referred to as muscle) is one of the three types of vertebrate muscle tissue, the other being cardiac muscle and smooth muscle. They are part of the voluntary muscular system [1] and typically are attached by tendons to bones of a skeleton. [2][3] The skeletal muscle cells are much longer than in the ...
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 completely autonomous.
The musculoskeletal system provides form, support, stability, and movement to the body. The human musculoskeletal system is made up of the bones of the skeleton, muscles, cartilage, [1] tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system's primary functions ...
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.

Thoracic diaphragm. The thoracic diaphragm, or simply the diaphragm (/ ˈdaɪəfræm /; [1] Ancient Greek: διάφραγμα, romanized: diáphragma, lit. 'partition'), is a sheet of internal skeletal muscle [2] in humans and other mammals that extends across the bottom of the thoracic cavity. The diaphragm is the most important muscle of ...
A tendon or sinew is a tough band of dense fibrous connective tissue that connects muscle to bone. It sends the mechanical forces of muscle contraction to the skeletal system, while withstanding tension. Tendons, like ligaments, are made of collagen. The difference is that ligaments connect bone to bone, while tendons connect muscle to bone.
The body consists of many different types of tissue, defined as cells that act with a specialised function. [8] The study of tissues is called histology and is often done with a microscope. The body consists of four main types of tissues. These are lining cells , connective tissue, nerve tissue and muscle tissue. [9]
