ANATOMY FINAL EXAM REVIEW
CORRECT 100%
synovial membranes - ANSWERConnective tissue membranes that cover joints and
secrete a lubricating fluid to lubricate joints
physiology - ANSWERthe study of the function of the body
actin and myosin - ANSWERproteins in muscle cells that slide past each other creating
the force of contraction
orbicularis oris - ANSWERmuscle that puckers the lips. Kissy, Kissy
anatomy - ANSWERThe study of the structures of the body
calcium ions - ANSWERServes as the actual "trigger" for muscle contraction by
removing the inhibition of the troponin molecules
yellow bone marrow - ANSWERfatty tissue found in the medullary cavity of most adult
long bones
melanin - ANSWERA pigment that gives the skin its color
midsagittal plane - ANSWERPlane that divides the body into a right and left side
keratin - ANSWERThe protein in epidermal cells that makes the skin relatively
waterproof is
anatomical position - ANSWERBody facing forward, feet are parallel to each other,
arms are at he sides with the palms facing forward
foramen - ANSWERRound or oval opening through a bone
myelin - ANSWERA layer of fatty tissue segmentally encasing the fibers of many
neurons; enables vastly greater transmission speed of neural impulses as the impulse
hops from one node to the next.
nodes of Ranvier - ANSWERGaps 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).
coronal/frontal plane - ANSWERvertical body plane, divides body into front and back
sections (anterior and posterior) standing
, transverse plane - ANSWERhorizontal plane that divides the body into superior (upper)
and inferior (lower) portions
ventral cavity - ANSWERAnterior surface of torso; divided by diaphragm muscle into
upper thoracic cavity and abdominopelvic cavity
dorsal cavity - ANSWERback part of the body; two subdivisions are cranial and spinal
reflex arc - ANSWERsensory receptor, sensory neuron, motor neuron, and effector that
are involved in a quick response to a stimulus
white matter - ANSWERThe portions of the central nervous system that are abundant in
axons rather than cell bodies of neurons. The colour derives from the presence of the
axon's myelin sheaths
gray matter - ANSWERBrain and spinal cord tissue that appears gray with the naked
eye; consists mainly of neuronal cell bodies (nuclei) and lacks myelinated axons.
sebaceous glands - ANSWERGlands that produce an oily substance called sebum,
which discharges along the shafts of the hairs.
muscular system - ANSWERAllows manipulation of the environment, locomotion, and
facial expression. Maintains posture & produces heat.
dendrites - ANSWERA neuron's bushy, branching extensions that receive messages
and conduct impulses toward the cell body.
integumentary system - ANSWERProvides a barrier, aids in thermoregulation, protects
against UV light, allows UV light to convert cholesterol into vitamin D, and aids in the
sensation of touch are all functions of this system.
endocrine glands - ANSWERDuctless or tubeless organs or groups of cells that secrete
hormones directly into the bloodstream
exocrine glands - ANSWERGlands that release their secretions through tubelike
structures called ducts directly to the organs that use them. Examples include glands
that release sweat, tears, and digestive juices.
fibrous connective tissue - ANSWERA dense tissue with large numbers of collagenous
fibers organized into parallel bundles. This is the dominant tissue in tendons and
ligaments.
Central nervous system - ANSWERConsists of the brain and spinal cord
peripheral nervous system - ANSWERCranial and spinal nerves
