brain and spinal cord
Includes nerves extending from the brain
& spinal cord
Sub-division of motor nervous system;
involuntary control
Sub-division of the motor nervous system; voluntary control
Division of PNS carrying information from
environment to CNS
Type of neuroglia in CNS that has a immune
function
Type of neuroglia in PNS that forms the myelin
sheath
Type of CNS neuroglia that acts as a blood-brain barrier; connects neurons
to capillaries
Type of neuroglia that produce & circulate
cerebrospinal fluid in the CNS
Type of neuroglia in the CNS that forms myelin
sheath
long process connecting soma to terminals
Processes that gather/detect information from receptors or nearby
cells
secrete neurotransmitters
Involved in saltatory conduction in myelinated
axons
Location of hereditary information/instructions
for building protein
moves sodium & potassium ions against
their gradients
Nerve cell receives enough stimulation to
generate an action potential
Occurs when Na channels close and K channels
open following an action potential
Occurs when K ions try to reach their equilibrium
potential
Period of time when the neuron cannot be
stimulated following an action potential
type of neuron in the brain and spinal cord
(functional classification)
Type of impulse conduction where the
action potential “jumps” from node to node
- 70 mV; membrane is “polarized” w/ more + charges outside than
inside
Sensory neuron interneuron motor
neuron
Type of neuron with lots of dendritic processes
(structural classification)
