|
|
Term
| how cardiac muscle uses movement |
|
Definition
| this muscle contracts and peristaltic wave motion forces blood through the vessels |
|
|
Term
| how smooth muscle tissues uses movement |
|
Definition
| this muscle contracts and peristaltic waves are conducted along the entire length of the digestive tract as well as the ureter connecting the kidneys to the bladder |

|
|
Term
|
Definition

|
|
Term
|
Definition
| is usually attached to bones that remain stationary during a desired action. these tendons tend to be short and broad |
|
|
Term
|
Definition
| is usually attached to bones that are movable during a desired action these tendons are typically long and narrow |
|
|
Term
|
Definition
| the contractile portion of the muscle |
|
|
Term
|
Definition
| a collection of desnely packed collagen and elastic fibers that attach muscle to bone; usually fuse with bone and sometimes cartilage |
|
|
Term
|
Definition
| strong, white, flat portions of fascia connecting halves of symmetrical parts. the junction point is called raphe |
|
|
Term
|
Definition
| superficial, deep, subserous |
|
|
Term
|
Definition
| under skin, it attaches skin to muscle allowing suppleness or strong attachment. it is thin on the back of the hand and thicker on the abdominal wall |
|
|
Term
|
Definition
| this type lines the body wall and extremities it holds muscles together and contains no fat |
|
|
Term
|
Definition
| covers the external surfaces of the viscera (organs) in the thoracic and abdominal cavities |
|
|
Term
|
Definition
| these are located in the foot ankle wrist and hand. these are lined by a synovial membrane which allows for the smooth operation of tendons while preventing its slipping. inflammation of these sheaths is called tendinitis or tenosynovitis. the best remedy is rest and the use of anti-inflammatory medications |
