1. Anatomy defintion studies the structure of body parts and their
relationships to one another
2. Physiology definition concerns the function of the body, how the
body parts work and carry out their life sus-
taining activities
3. positive feedback mechanism result or response enhances the original stim-
ulus so that the response is accelerated. moves
in the same direction as the initial change.
usually control infrequent events that do not
require continuous adjustments. +feedback
mechanisms are often referred to as cas-
cades.
examples: blood clotting, birth
4. negative feedback mechanism causes the variable to change in the opposite
direction to that of the initial change, returning
it to its "ideal" value
the endocrine system is important in main-
taining homeostasis. a good example of a hor-
monal negative feedback mechanism is the
control of blood sugar by insulin. As blood
sugar rises, receptors sense the change and
the pancreas (control center) secretes insulin
into the blood
goal of neg. feedback system: prevent severe
changes within the body

examples: heart rate, blood pressure, rate and
depth of breathing, blood levels of Oxygen,
carbon dioxide and minerals
5. regional terms must know: refer to other quizlet: Regional
Terms Anatomy
6. anatomical positon body is erect with feet slightly apart, films face
forward and thumbs point away
7. directional terms help us explain where one body part is in
relation to another
ex: eyes are medial to the ears
head is superior to the abdomen
8. axial head neck and trunk
9. appendicular all limbs
10. sagittal plane divides body into right or left parts
11. frontal plane divides the anterior from the posterior
12. transverse divides the superior from the inferior
13. dorsal body cavity contains cranial & vertebral cavities
protects the fragile nervous system
14. what does the cranial, vertebral cavity brain, spinal cord
contain
15. ventral body cavity contains the thoracic and abdominopelvic cav-
ity - divided by the diaphragm
