BIOS-251: Exam 1 Review
The study of human structure
Anatomy
The study of human function
Physiology
A tendency for organisms to maintain a balanced or constant internal state
Homeostasis
A state of balance
Equilibrium
Consequences of homeostatic imbalance
Illness or death
Thermoregulation Process
A feedback loop in which a system responds to a change by reversing that change, or by decreasing the
rate at which the change is occurring. (Ex. thermoregulation)
Negative Feedback Loop
, A feedback loop in which a system responds to a change by amplifying that change. (Ex. childbirth)
Positive Feedback Loop
Changes, occurring within or outside the body, that affect homeostasis
Stimuli
Detects and sends messages to the control center
Receptors
Processes the signal, alerts the effector about the detected change, and gives instructions
Control Center
An organ or cell that acts in response to a stimulus; handles the issue
Effector
Divides a human body into anterior and posterior sections
Frontal Plane or Coronal Plane
Divides the human body into equal left and right sections
Midsagittal Plane
Divides the human body in half, creating two sections; top and bottom
