QUESTIONS ANSWERS VERIFIED A+
◉ 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
◉ dorsal body cavity.
Answer: contains cranial & vertebral cavities
protects the fragile nervous system
◉ what does the cranial, vertebral cavity contain.
Answer: brain, spinal cord
◉ ventral body cavity.
