HS Musculoskeletal
Term | Definition |
---|---|
skeleton | the framework for the human body that contain 206 bones |
long bones | found in the arms and legs; consist of a shaft and two rounded ends |
short bones | found in wrists and ankles; round or cube shaped |
flat bones | found in ribs and skull; relatively thin and may be curved |
irregular bone | found in spinal column and face; oddly shaped that are not flat |
joint | the areas where two bones join together |
fixed joints | do not permit any movement at all; found in skull |
slightly movable joints | allow for limited movement; found in vertebrae of spine and attach to sternum |
freely movable joints | allow for wide range of movement; found in knees, elbows, shoulders, etc. |
range of motion | the complete extent of movement that the joint is normally capable of without causing pain |
cartilage | a tough, fibrous substance found in joints and other parts of the body; in slightly movable joints, it acts as a "shock absorber" |
ligaments | very strong bands of fibrous tissue that cross over the joint capsule, attaching to one bone to another and stabilizing the joint |
tendons | bands of connective tissue that connect muscle to bone |
muscle tone | the steady contraction of the skeletal muscles |
flexion | bending of a joint |
extension | straightening of a joint |
abduction | moving a body part away from the midline of the body |
adduction | moving a body part towards the midline of the body |
rotation | twisting or turning of a joint |
supination | rotation of the palm so that it is facing up or forward |
pronation | rotation of the palm so that it is facing down or backward |
eversion | rotation of the foot outward |
inversion | rotation of the foot inward |
dorsiflexion | bending the foot upward at the ankle by pulling the toes towards the head |
plantar flexion | flexing the arch of the foot by pointing the toes downward |
atrophy | the loss of muscle size and strength |
osteoporosis | excessive loss of bone tissue; bone becomes extremely fragile |
arthritis | inflammation of the joints, usually associated with pain and stiffness |
muscular dystrophy | a general term for a group of disorders that cause the skeletal muscles to become progressively weaker over time |
fracture | a broken bone |
closed fracture | the bone is broken, but the broken ends do not protrude through the over lying skin |
open fracture | the bone is broken, and the sharp ends of the broken bone have broken through the skin |
greenstick fracture | the bone bends and splinters, but it does not break all the way through |
impacted fracture | the bone is broken all the way through, and the broken ends of the bone are jammed into each other |
comminuted fracture | the bone is splintered into several little peices |
spiral fracture | the break circles around the bone in a winding fashion |
reduction | the process of bringing the broken ends of the bone into alignment |
fixation | the process of holding the bone in one position until the fracture heals |
traction | the ends of the bones are placed in the proper alignment and then weight is applied to exert a constant and keep the bone in alignment |
trapeze bar | a device that is attached to the overhead frame of a person's bed; used to assist with movement |
amputation | the removal of all or part of an arm or leg |
stump | the end of the amputated limb that is left after surgery |
phantom pain | the feeling that the amputated body part is still present, after an amputation |
active range of motion | patient or resident performs all exercises independently |
passive range of motion | the nursing assistant or nurse moves the patient's or resident's joints through the exercises, without active involvement on the part of the person |
active assistive range of motion | the patient or resident performs the exercises with some hands-on assistance from the nursing assistant or nurse |
gangrene | death of tissue caused by loss of blood supply followed by bacterial invasion |
