The nervous system has a network of neurons and
controls body functions, receives input, transmits
Nervous system
information, integrates input, generates commands
and outputs to motor systems.
Location of the CNS Brain and Spinal Cord
PNS (peripheral nervous Somatic and autonomic, which both branch to
system) afferent and efferent nerves.
Anterior vs. Posterior Anterior (front), posterior (back)
Superior (above)
Superior vs Inferior
Inferior: (below)
Medial vs lateral Medial is toward midline, lateral is away from midline
ipsilateral: same side
Ipsilateral vs contralateral
contralateral: opposite side
afferent (sensory and arriving to brain) and efferent
Afferent vs efferent
(motor and exiting brain)
Sagittal plane Divides body into right and left planes
Coronal/frontal Divides the body into anterior and posterior plane
Axial/transverse Divides the brain structure into upper and lower
Provides physical support, nutrient flow and nerve
Neuroglia

Neurons (information carriers) and Glia (support
Cell types in NS
cells)
What do astrocytes Provide nutrients, regulate external cellular fluid,
(CNS) do clean up debris
What does microglia do Immune cells, smallest glial cells, protect brain from
(CNS) invading microorganisms
What does CNS myelination cells, extend processes to multiple
oligodendroglia do axons sections, produce myelin sheath
(CNS)
What do schwann cells PNS myelination cells, single myelin section,
do (PNS) support cells
Myelin is made of lipid and protein and acts as an
Why is myelination insulator during conduction of electrical impulses
important? through nerves surrounding the axon, and increases
the speed at which impulse travels
What happens when you Nerve impulses slow down or stop
lose myelination?
Information processing and transmitting element in
Neurons
the NS, there is 100 to 100 billion in NS
1. Cell body: integrates signals
Parts of the cell body
2. Dendrites: receives signals
and what they do
3. Axon: conduit to send signals
Information flow through neurons. Dendrites collect
Electrical neuron electrical signals, cell body integrates incoming
signaling signals and generates outgoing signal to axon, axon
passes electrical signal to dendrites of cell.
Chemical neuron Synapse: presynaptic neuron, synaptic cleft and
signaling postsynaptic neuron.
What happens in Presynaptic is axon terminal where
presynaptic and neurotransmitters are released, postsynaptic is the
postsynaptic neurons dendrite where the neurotransmitter binds.
Fundamental unit of neural communication,
Action potential depolarizing potential, once generated it is
propagated down the axon
