any of four pairs of muscles extending from the cervical vertebrae to the second rib; involved in moving the neck and in breathing

one of two thick muscles running from the sternum and clavicle to the mastoid and occipital bone; turns head obliquely to the opposite side; when acting together they flex the neck and extend the head

either of two muscles in the shoulder region that move the shoulders and arms

either of two skeletal muscle in each leg arising from the tibia; provides for movement of the foot

either of two flat triangular muscles of the shoulder and upper back that are involved in moving the shoulders and arms

any of the skeletal muscles of the face

muscle extending from the temporal fossa to the coronoid process of the mandible; acts to raise the mandible and close the jaws

a muscle that produces or assists in pronation

a muscle (especially in the forearm) that produces or assists in supination

a muscle that serves to lift some body part (as the eyelid or lip)

(physiology) a muscle that opposes the action of another

a muscle that contracts while another relaxes

a muscle that relaxes while another contracts

any of various straight muscles

a muscle that contracts without conscious control and found in walls of internal organs such as stomach and intestine and bladder and blood vessels (excluding the heart)

the smooth muscle forming the wall of the uterus

an internal ring of smooth muscle formed by circular fibers of the rectum

a ring of muscle that contracts to close an opening

a sphincter that is not recognizable at autopsy because its resting arrangement cannot be distinguished from adjacent tissue

the sphincter muscle of the anus

any of several muscles associated with the atrioventricular valves

a bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract

a node of specialized heart muscle located in the septal wall of the right atrium; receives impulses from the sinoatrial node and transmits them to atrioventricular bundle

the middle muscular layer of the heart wall

a specialized cardiac muscle fiber that is part of the Purkinje network

a network of Purkinje fibers that carry the cardiac impulse from the atrioventricular node to the ventricles of the heart and causes them to contract

muscle tissue that does not appear striated under the microscope; has the form of thin layers or sheets
