Physiology
How the body and body parts work and function
Anatomical position
Normal standing position with everything forward and palms facing out
Sagittal
Divides body into right and left halves
Frontal
Divides body in front and back halves
Transverse
Divides body into top and bottom halves
Receptor
Nerve that responds to parts of the stimuli
What pathway does the receptor use
Afferent
Control center
Receives and analyzes information from sensory receptors, then sends a command stimulus
Effector
An organ/gland/muscle capable of being activated by nerve endings
What pathway does the effector use?
The efferent pathway
Negative feedback mechanisms causes what to happen
The stimulus to decline or end
Examples of negative feedback mechanisms
Regulate temperature, heart rate, blood pressure, breathing rate, and blood levels
What does positive feedback mechanism cause
Enhances the stimulus
Examples of positive feedback mechanisms
Labor, blood clotting
Homeostatic imbalance
Negative feedback mechanisms are overwhelmed and destructive positive feedback mechanism take over resulting in disease
