College | Questions with 100% Verified Answers | Latest Update
Question: Anatomy defintion
Answer:
studies the structure of body parts and their relationships to one another
Question: Physiology definition
Answer:
concerns the function of the body, how the body parts work and carry out their life sustaining
activities
Question: positive feedback mechanism
Answer:
result or response enhances the original stimulus 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 cascades.
examples: blood clotting, birth
Question: negative feedback mechanism
Answer:
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 maintaining homeostasis. a good example of a hormonal
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
Question: regional terms
Answer:
must know: refer to other quizlet: Regional Terms Anatomy
, Question: anatomical positon
Answer:
body is erect with feet slightly apart, films face forward and thumbs point away

Answer:
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
