Nervous system functions and vocabulary
Nervous System Function
Responsible for the control of the body and communication among its parts
Sensory Nerves
Carry signals from sensory receptors to the spinal cord
Motor Nerves
Send stimulus info from CNS to the organs (CNS → PNS)
PNS
Peripheral Nervous System
CNS
Central Nervous System
When the body is using the sympathetic nervous system:
Increased heart rate
Stimulate glucose release
Digestion stops
Adrenaline / Cortisol is released
When the body is using the parasympathetic nervous system:
Stimulates stomach activity
Slows heart rate
Inhibits glucose release
Neurologists
Specialists who treat diseases of the brain and spinal cord, peripheral nerves and muscles.
Reflex Arc
A reaction that involves only a few neurons and the information goes only from your body to your spinal cord.
Brain
Controls bodily functions
Spinal cord
Connects the PNS and the CNS
Stroke
When blood circulation is cut off from brain tissue and part of the brain tissue dies
Somatic Nervous System
Controls voluntary reactions
Autonomic Nervous System
Controls involuntary actions
Parasympathetic
When nothing is stimulating/stressing the organism out
Sympathetic
When the body is introduced with a stimulus that causes the body to prepare for action
Sensory Receptor
A receptor that responds to a signal in the environment
Sensory Neuron
Carry signals from sensory receptors to the spinal cord
Effector
Structure by which animal responds (muscle, gland, etc)
