are the long, slender cells that make up muscles. Each muscle consists of group fibers that are held togehter by connective tissue and enclosed in fibrous sheath.
sheet of fibrous connective tissue that covers, supports, and seperates muscles or groups of muscles
a narrow band of nonelastic, dense fibrous connective tissue that attaches a muscle to a bone.
located in the walls of internal organs such as the digestive tract, blood vessels, and ducts leading form glands
also known as myocardium or cardiac muscles, form the muscular walls of the heart
tightnening of a muscle. As the muscle contracts, it become shorter and thicker, causing the belly (center) of the muscle to enlarge
occurs when a muscle returns to its original form. As the muscle relaxes it becomes longer, and thinner, and the belly is no longer enlarged.
the act of raising or lifting a body part, such as rising te ribs when breathing in levator is a muscle that raises a body part.
the act of lowering a body part, such as lowering the ribs when breathing out. A depressor, is a muscle that lowers a body part.
circular movement around an axis such as the shoulder joint. An axis is an imaginary line that runs lenghtwise through the center of the body
circular movement of a limb at the far end. Ex swinging motion of the far end of the arm.
act of rotating the arm or leg so that the palm of the hand or sole of the foot, is turned forward or upward.
act of rotating the arm or leg so that the palm or sole of the foot is turned downward or backward.
less movable attachment, the place where the muscle begins. the origin is located nearest the midline of the body or on a less movable part of the skelton.
Other Muscles indicate their location by including the term lateralis and medials in their names,
Lateralis means toward the side. Medials means toward the midline.Ex VAtus laterials and the vastus medials. These muscle flex and extend at the leg at knee.
Some muscles indicate their location by including external and internal in their names.
External or superfiscial mean near the surface and internal means deeper location. The external oblique and internal oblique flex and rotate the spinal column and compress the abdomen.
slanted or at an angle. Ex the external oblique and internal oblique muscles have a slanted alignment
straight alignment with the vertical axis of the body. Ex the rectus abdominus muscle has a straight alignment.
a ring like muscle that tightly constricts of the oppening of a passageway. A sphincter is named fpr the passage involved. Ex anal sphincter closes the anus
in a crosswire direction. An example is the transverse abdomins muscle, which has a crosswise alignment.
a physician who specializes in the diagnosis and treatment of arthritis and disorders such as osteoporosis, fibromyalgia, and tendonitis that are characterized by inflammation in the joints and connective tissue
a condition of abnormal muscle tone that causes the impairment of voluntary muscle movements
a neuromuscular disorder characterized by tge slow relaxation of the muscles after a voluntary contraction.
also known as wryneck, is a stiff neck due to spasmodic contraction of the neck muscles that pull the head toward the affected side. Spasmodic means relating to spasm and torticollis means a contraction, or shortening of the muscles of a neck.
paralysis of both legs and the lower part of the body. An individual affected with parapelgia is known as paraplegic.
also known as tenoectomy is the surgical resection of a protion of a tendon or tendon sheath.
also known as a tendomoty is the surgical division of a tendon for relief of a deformity caused by abnormal shortening of a muscle such as strabisum.
moves toward the midline. During adduction the arm moves inward toward the side of the body.
the movement that bends the foot upward at the ankle. Pointing the toes and foot upward decreases the angle between the top of the foot and the front of the leg.
