Nerve cell axons inside the CNS called?
Sometimes the term ganglia is used as in the sympathetic and parasympathetic ganglia of the autonomic nervous system.
Are axons most located and protected within the CNS?
axons
Do the sympathetic fibers leave the CNS at the thoracolumbar region?
All preganglionic sympathetic fibers leave the CNS at the thoracolumbar region, yes.
What are the three types of neuron?
Functional types of neurons: 1. sensory (afferent) neurons - input to CNS from sensory receptors; dendrites located at receptors, axons in nerves, cell bodies in ganglia outside the CNS 2. motor (efferent) neurons - output from CNS to effectors cell bodies and dendrites located in the CNS, axons in nerves 3. interneurons - communicate and integrate information within the CNS; located entirely within the CNS
What outflow of the sympathetic division occurs from which regions of the CNS?
Thoracolumbar
Nerve cell axons inside the CNS called?

Are axons most located and protected within the CNS?
axons
Collection of nerve cell bodies found outside CNS?
In the peripheral nervous system, which is outside the central nervous system (CNS), collections of nerve cell bodies are called ganglia.
What are collections of neurons?
nuclei in the CNS, ganglia in the PNS
What are groups of neuronal cell bodies in the CNS?
A collection of cell bodies in the CNS is called a nucleus. The equivalent in the PNS is called a ganglion. There are three nuclei in the cerebrum known collectively as the Basal Ganglia but this is a misnomer as they should be called nuclei.
What are the collection of nerve cell bodies inside the CNS?
These collections are called ganglia. Ganglia often interconnect with other ganglia to form a complex system of ganglia known as a plexus.
Do the sympathetic fibers leave the CNS at the thoracolumbar region?
All preganglionic sympathetic fibers leave the CNS at the thoracolumbar region, yes.
What is the difference between clusters of cell bodies called nuclei and those know as ganglia?
Nuclie are in the CNS, while ganglia are in the PNS.
What part of the CNS gives rise to sympathetic nerves?
The parts of the CNS that give rise to sympathetic nerves are the thoracic and lumbar regions of the spinal cord.
What are the three types of neuron?
Functional types of neurons: 1. sensory (afferent) neurons - input to CNS from sensory receptors; dendrites located at receptors, axons in nerves, cell bodies in ganglia outside the CNS 2. motor (efferent) neurons - output from CNS to effectors cell bodies and dendrites located in the CNS, axons in nerves 3. interneurons - communicate and integrate information within the CNS; located entirely within the CNS
Collection of cell bodies found outside the cns?
neurons is the incorrect answer. The correct answer is ganglia.
What outflow of the sympathetic division occurs from which regions of the CNS?
Thoracolumbar
