Intro To Anatomy And Physiology

Question 1

Cellular

Answer 1

Basic unit of structure/function associated with life; maintain an interior environment that is different than the exterior environment; specialized functions in mammals

Question 2

Tissue

Answer 2

Groups of cells; 4 main types (muscle, epithelial, nervous, connective tissue)

Question 3

Organ

Answer 3

Functional unit made up of MULTIPLE tissue types; performs a specific function or set of functions

Question 4

System

Answer 4

Collection of related organs that perform a specific task

Question 5

Homeostasis

Answer 5

A dynamic ‘steady-state’ of internal environment
Stable ‘maintenance of optimal conditions’ our cells need to live
‘Normal set-point’ for physiological parameters

Question 6

Homeostatic Control Systems

Answer 6

Detect deviations from normal
Integrate this information with needs of the body
Make appropriate adjustments to restore ‘normal set-point’

Local or Systemic

Always coordinated

Question 7

Negative Feedback Loop

Answer 7

Response to stimulus reduces original stimulus or causes opposite effect

Question 8

Positive Feedback Loop

Answer 8

Response to stimulus increases original stimulus

Question 9

Feedforward

Answer 9

Anticipation-action before the stimulus has occurred
