CHAPTER 1:intro to A&P Flashcards
is the study of external features, such as bony projections, which serve as landmarks for locating deeper structures
surface anatomy
refers to the specific relationship of the many individual parts of an organism, from cell organelles to organs, interacting and working together.
organization
is change in cell structure and function from generalized to specialized. These differentiated cells form tissues and organs.
differentiation
is the existence and maintenance of a relatively constant environment within the body despite fluctuations in either the external environment or the internal environment.
Homeostasis
such as sweating or shivering, normally maintain body temperature near an average normal value, or set point.
Homeostatic Mechanism
What is the Homeostatic mechanisms governed by ?
nervous system and Endocrine System
What is the normal body temperature? (in celcius)

How much water do we have in our body
70
Something that
causes a noticeable
change that leads to
a response
stimulus
where stimulus is detected
Receptors
is responsible for receiving the set of information and coordinating a response
Control center
Directed by the control center the effector brings the
organism back to homeostasis
Effectors
is when any deviation from the set point is made smaller or is
resisted.
Negative feedback
How is Homeostasis maintained
through control mechanism
occurs when the initial stimulus further stimulates the response.
positive feedback
