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
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
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
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
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
This part of the body contains the appendages
This plane divides the body into right and left parts
This plane divides the body into superior and inferior parts
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
How many abdominopelvic regions are there
How many abdominopelvic quadrants are there
The oral cavity is called the
Name other kinds of cavities found in the body
synovial,nasal, orbital, middle ear,
synovial cavities are another name for what kind of cavities
