1. synovial membranes Connective tissue membranes that cover joints and secrete a lubricating
fluid to lubricate joints
2. physiology the study of the function of the body
3. actin and myosin proteins in muscle cells that slide past each other creating the force of
contraction
4. orbicularis oris muscle that puckers the lips. Kissy, Kissy
5. anatomy The study of the structures of the body
6. calcium ions Serves as the actual "trigger" for muscle contraction by removing the
inhibition of the troponin molecules

Body facing forward, feet are parallel to each other, arms are at he sides
with the palms facing forward
12. foramen Round or oval opening through a bone
13. myelin A layer of fatty tissue segmentally encasing the fibers of many neurons; en-
ables vastly greater transmission speed of neural impulses as the impulse
hops from one node to the next.
14. nodes of Ranvier Gaps in the myelin sheath of the axons of peripheral neruons. Action
potentials can 'jump' from node to node, thus increasing the speed of
conduction (saltatory conduction).
15. negative feedback A primary mechanism of homeostasis, whereby a change in a physiological
variable that is being monitored triggers a response that counteracts the
initial fluctuation.
