Test 1 Anatomy & Physiology - Chapters 1-4 Updated
2025-2026 Exam Test Questions And Verified
Answers
Anatomy defintion - ✔✔ANSWER ✔✔-studies the structure of
body parts and their relationships to one another
Physiology definition - ✔✔ANSWER ✔✔-concerns the function of
the body, how the body parts work and carry out their life
sustaining activities
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
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
regional terms - ✔✔ANSWER ✔✔-must know: refer to other
quizlet: Regional Terms Anatomy
, anatomical positon - ✔✔ANSWER ✔✔-body is erect with feet
slightly apart, films face forward and thumbs point away
directional terms - ✔✔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
axial - ✔✔ANSWER ✔✔-head neck and trunk
appendicular - ✔✔ANSWER ✔✔-all limbs
sagittal plane - ✔✔ANSWER ✔✔-divides body into right or left
parts
frontal plane - ✔✔ANSWER ✔✔-divides the anterior from the
posterior
transverse - ✔✔ANSWER ✔✔-divides the superior from the
inferior
