Muscles
Muscles

Contractile tissue that produces movement in animals.

Muscle, Skeletal
Muscle, Skeletal

A subtype of striated muscle, attached by TENDONS to the SKELETON. Skeletal muscles are innervated and their movement can be consciously controlled. They are also called voluntary muscles.

Sarcoplasmic Reticulum
Sarcoplasmic Reticulum

A network of tubules and sacs in the cytoplasm of skeletal muscles that assist with muscle contraction and relaxation by releasing and storing calcium ions.

Muscle, Smooth
Muscle, Smooth

Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant. (From Stedman, 25th ed)

Myometrium
Myometrium

The smooth muscle coat of the uterus, which forms the main mass of the organ.

Muscle, Smooth, Vascular
Muscle, Smooth, Vascular

The nonstriated, involuntary muscle tissue of blood vessels.

Tunica Media
Tunica Media

The middle coat of blood vessel walls, composed principally of thin, cylindrical, smooth muscle cells and elastic tissue. It accounts for the bulk of the wall of most arteries. The smooth muscle cells are arranged in circular layers around the vessel, and the thickness of the coat varies with the size of the vessel.

Myocardium
Myocardium

The muscle tissue of the HEART. It is composed of striated, involuntary muscle cells (MYOCYTES, CARDIAC) connected to form the contractile pump to generate blood flow.

Papillary Muscles
Papillary Muscles

Conical muscular projections from the walls of the cardiac ventricles, attached to the cusps of the atrioventricular valves by the chordae tendineae.

Myocytes, Cardiac
Myocytes, Cardiac

Striated muscle cells found in the heart. They are derived from cardiac myoblasts (MYOBLASTS, CARDIAC). Myoblasts, Cardiac; Myofibrils;

Muscle, Striated
Muscle, Striated

One of two types of muscle in the body, characterized by the array of bands observed under microscope. Striated muscles can be divided into two subtypes
