Deffine Anatomy
ivestigates the body' structure
Define physiology
investigates the processes or functions of living things
Name in order the 6 levels of functional organization
1) Chemical
2) Cell
3) Tissue
4) Organ
5) Organ system
6) organism
Define the chemical level
Interaction of atoms
define the cell level
structural and functional unit of all living organisms
define the tissue level
group of similar cells and the materials surrounding them
define the organ level
one or more tissues functtioning together
define the organ system level
group of organs functioning together
Define an organsim
any living thing
List the 6 characteristics of life
1) Organization
2) Metabolism
3) Responsiveness
4) Growth
5) Development
6) Reproduction
Define organization
condition in which there are specific relationships and functions
define metabolism
all chemical reactions of the body
define responsiveness
ability to sense changes and adjust
define growth
increase in size and/or number of cells
define development
changes in an organism over time
define differentiation
changes from general to specific
define morphogenesis
changes in shape of tissue/ organs
define reproduction
new cells or organisms
define median
through the midline
define saggital
to the left or the right of the midline
define frontal
divides the body into posterior and anterior sections
define transverse
divides the body in superior and inferior sections
define oblique
other than a right angle
define homeostasis
ability to maintain relatively stable internal conditions even though the outside world changes continuously
list step 1 in the homestasis cyle
11. stimulus produces change in variable
list step 2 in the homeostasis cycle
2. changed detected by receptor
list step 3 in the homeostasis cycle
Input: information sent along afferent pathway to control center
list step 4 in the homeostasis cycle
4. Output: information is sent along the efferent pathway to the effector
list step 5 in the homeostasis cycle
5. Response: effector feeds back to influence magnitude of stimulus and returns varible back to homeostasis
define positive feedback
the result or response enhances the original stimulus so that the output is accelerated
define negative feedback
the output shuts off the original stimulus or reduces it's intensity
give and example of positive feedback in homeostasis
the release of oxytocin to cause uterine contractions during labour
give an example of negative feedbaxk in homeostasis
the regulation of bdy temperature
