What are the three coponents for homeostatic control
|
receptor, control center, effector
|
|
|
from the three homestatic components which one determines the range the variable is to be maintained
|
the control center
|
|
|
Most homeostatic mechanisms are positive feedback
|
F negative
|
|
|
Is it positive or negative feedback when the control center causes the variable to change in an opposite direction to the initial change
|
negative
|
|
|
The nervous system is more important in maintaining homeostasis than the endocrine system
|
F equally imp
|
|
|
Blood glucose level maintenance is neg or pos feedback
|
negative
|
|
|
In positive feedback the body's response is to ----the stimulus
|
enhance, and make the stimulus go in the right direction, not fight it
|
|
|
In positive feedback the original stimuli goes closer to the original value or further away
|
farther away
|
|
|
Positive feedback mechanisms are referred to as cascades
|
T
|
|
|
Positive feedback is rare in the body

|
|
Give 2 examples of positive feedback
|
contractions (labor), blood clotting
|
|
|
Most disease is regarded as a result of homeostatic disturbance
|
T
|
|
|
When do we start seeing homeostatic imbalance
|
with age, and when the negative feedback system is overwhelmed
|
|
|
What is the anatomical position
|
stand at attention with palms face forward
|
|
|
Allow us to explain where one body structure is in relation to another
|
directional terms
|
|
|
This part of the body contains the head, neck, and trunk
|
axial
|
|
|
This part of the body contains the appendages
|
appendicular
|
|
|
This plane divides the body into right and left parts
|
sagittal
|
|
|
This plane divides the body into superior and inferior parts
|
transverse
|
|
|
a transverse section is also called a
|
cross section
|
|
|
THe two large cavities that run alongside the axial portion of the body are the
|
dorsal and ventral
|
|
|
The ventral body houses
|
the viscera
|
|
|
The dorsal body houses
|
the brain and spinal cord
|
|
|
THe walls of the ventral cavity and its organs are covered by this
|
the serous membrane
|
|
|
The serosa that lines the organs of the ventral cavity is called
|
the visceral serosa
|
|
|
The serosa that lines the walls of the ventral cavity
|
parietal serosa
|
|
|
The organ and wall serosa are seperated by
|
serous fluid
|
|

Name other kinds of cavities found in the body
|
synovial,nasal, orbital, middle ear,
|
|
|
synovial cavities are another name for what kind of cavities

|
|
Synovial cavities emit a fluid to reduce friction between bones
