Central Nervous System
(CNS) brain and spinal cord.
Peripheral Nervous system
Body Nerves that connect to the central nervous system (brain and spinal cord).
Connects the central nervous system to the body's organs and limbs.
Autonomic Nervous System
Controls involuntary bodily functions (not consciously controlled), such as
breathing, the heartbeat, and digestive processes
Somatic Nervous System
Controls voluntary bodily functions (consciously controlled), such as controlling
skeletal muscles
2 Major Functions of Nervous System
1. Sensory Reception-end of peripheral neurons monitor
conditions( light,sound,temperature)
2. Integrative Functions- Sensory messages that get sent repeatedly get
remembered "motor functions" (subconscious actions)
Order of Stimulus (from sensory to effector)
1. Stimuli: physical or chemical signal (ex. hot room)
2. Nerve impulse (ex. sends signal to brain)
3. Effectors: muscle & glands react (ex. sweat glands start sweating)
Stimulus
Things that initiate nerve impulses (ex. hot room)
Effector

SUCCESS
Response (ex. Sweating)
Motor Functions
Complex muscle-and-nerve acts that produce movement (walking, writing, typing
running etc.)
"Electrochemical"
A nerve impulse is partially electric (change in polarity/charge) and partially
chemical (neurotransmitters)
Synapse
Where the nerve impulse is sent (connection of 2 neurons) .
Action Potential changes the charge of the synapse (causes electricity) and
Neurotransmitters are sent.
Myelin Sheath
Covering of Schwann Cells, Speeds up nerve impulses.
Axon
The long threadlike part of a nerve cell that carry the nerve impulse
Dendrites
Branch like extensions on a neuron that GET signals and connect to the synapse
Neurotransmitters
Chemicals that transmit signals across a synapse from one neuron to another
'target' neuron
Multipolar Neuron
Most of the brain/spinal cord & is mylinated
