Nervous System Review

What are the two main parts of the nervous system

what are the 2 main structures of the central nervous system

• idk

• brain and spinal cord

• spinal cord and cranium

• brain and spine

what are the two main parts of the peripheral nervous system

• idk

• spinal cord and brain

• spine and brain

• autonomic/somatic system

whatś the difference between neuron and glial cells

• they both function in the brain and spinal cords

• neurons conduct impulses and glial cells do not

• they both work the same

• neurons conduct impulses and glial cells do as well

what do axons do?

• produce nerve cells

• process and conduct impulses away from the nerve cell body

• provide movement and impluse signals for the cell body

• produce myelin sheath

what is the dendrite function

• recive input from other neurons

• speed up neurotransmission

• idk

• process and conduct impulses away from the nerve cell body

what do schwann cells do

• speed up neurotransmission

• produce myelin

• remove impulses from cell body

• recive input from other neurons

Astrocyte--

• produce myelin sheath around nerve fibers

• dispose of cellulr debris damaged neurons and pathogens

• produce myelin-speed up neuron cell bodies

• mop up excess ions-induse synapse-connect neurons to blood vessels

Microglia--

• dispose of cellulr debris damaged neurons and pathogens

• Derive from the brain and control the bodily functions

• dont do anything

• Line the ventral canal of spinal cord and ventricles of brain/circulate fluid

Ependymal----

• Produce myelin sheath around nerve fibers

• Line the ventral canal of spinal cord and ventricles of brain/circulate fluid

• Line the ventral canal of spinal cord and ventricles of brain/circulate blood flow

• Support clusters of neuron cell bodies (glial)
