The Central Nervous System is made up of the Brain and:
Spinal cord
The Peripheral Nervous System is made up of the Cranial and Spinal nerves, as well as the:
Ganglia
Clusters of neuron cell bodies located outside the CNS:
Ganglia
. This Nervous division receives sensory information from receptors and transmits it to the CNS:
Sensory afferent
This Nervous division transmits motor impulses from the CNS to muscles or glands:
Motor efferent
This Sensory division receives information about touch, pain, pressure, vibration, temperature, proprioception, and special senses:
Somatic sensory
This Sensory division transmits nerve impulses from blood vessels and viscera (temperature, and stretch) to the CNS:
Visceral sensory
This Motor division transmits nerve impulses from the CNS to skeletal muscles:
Somatic motor
This Motor division transmits nerve impulses from internal organs, smooth and cardiac muscle, and glands:
Autonomic motor
Type of nerve cell that initiates and transmits nerve impulses:
Neuron
Type of nerve cell that support and protects neurons:
Glial
The neuron cell body is responsible for receiving, integrating, and _____ nerve impulses
sending
The neuron dendrites are responsible for conducting nerve impulses ______ the cell body.
towards
The neuron axon is responsible for transmitting nerve impulses _______ from the cell body.
Away
The neuron structure can be unipolar, bipolar, or _____
Multipolar
Facilitate communication between sensory and motor neurons:
Interneurons
Physically protect, nourish and provide support for neurons:
Glial cells
Glial cells that help form the blood-brain barrier, regulate tissue fluid composition, provide support, replace damaged neurons, and assist neuron development:
Astrocytes
Glial cells that help form the cerebral spinal fluid:
ependymal
Glial cells that remove debris and respond to infections:
microglia
Glial cells that form myelin sheaths (speed up transmission) in the CNS:
Oligodendrocytes
Glial cells that regulate exchange between soma and surrounding fluid:
Satellite
Glial cells that form myelin sheaths in the PNS:
Schwann (neurolemmocytes)
Myelin sheaths support, protect, and ______ the axon
insulate
Process of nerve impulses jumping from neurofibril node to neurofibril node:
Salatory conduction
Process in which nerve impulses travel the entire length of an unmyelinated axon:
Continuous conduction
Damaged axons can regenerate upon these three factors:
Amount of damage, neurolemmocyte secretion of nerve growth factors, distance between site of damaged axon and effector organ
Give the three connective tissue wrappings, in order of inside to outside:
Endoneurium, perineurium, epineurium
Axons will terminate at either a neuron, muscle cell, or:
Gland cells
Process in which an axon transmits a nerve impulse at a specialize junction with another neuron:
Synapse
The Presynaptic neuron transmits nerve impulses toward a synapse, while a ______ conducts them away from the synapse.
Postsynaptic
Electrical synapses use gap junctions, while chemical synapses use:
Neurotransmitters
During a chemical synapse, the presynaptic membrane releases a ______ while the postsynaptic membrane receives the neurotransmitter by way of receptors.
Neurotransmitter
The two factors that influence the rate of impulse conduction:
Axons diameter, presence/absence of myelin sheath
