skeleton
~consists of 206 bones
~stores calcium, magnesium, phosphorus
bone marrow
~soft material found in the center of bones
~responsible for RBC production
skeletal muscles
~attached to bones by tendons
~provide body movement and posture
ligaments
~connect bones to bones
~encircle joints to add strength & stability
tendons
~connect muscles to bones
joint
~articulation of two bone surfaces
~provide stabilization and permit locomotion
synovium
~membrane that lines a joint's inner surfaces
~reduces friction in joints thru its production of synovial fluid
cartilage
~specialized tissue that serves as a smooth surface for articulating bones
~absorbs shock to joints

synaptic cleft
~small gap btwn nerve & muscle cell
acetylcholine
~neurotransmitter (chemical) that travels through the fluid to stimulate the muscle fiber
cholinesterase
~enzyme that breaks down acetylcholine after the message has been delivered
flexion
~the angle btwn two bones is decreased
~EX: arm bent @ elbow
extension
~angle btwn two bones is increased
~EX: leg is extended
hyperextension
~angle btwn two bones is greater than 180 degrees
abduction
~movement of an extremity away from the midline of the body
~EX: arms straight out
adduction
~movmement of an extremity toward the axis of the body
~EX: arms to the side
rotation
~movement of the bone around its longitudinal axis
~pivot motion
~EX: shaking head "no"
