where can the cell bodies of pseudounipolar neurons only be found?

dorsal root ganglion

what is the function of the cells that line the central canal of the spinal cord?

epedymal cells (regulates and produces CSF)

on the basis of its relative position and function, what kind of neuron joins sensory neurons to motor neurons?

interneuron

anterior horn cell

location= anterior gray horn of spinal cord structural class of neuron= multipolar neuron functional class of neuron= motor neuron

purkinje cell

location= cerebellum structural class of neuron= multipolar neuron functional class of neuron= interneuron

dorsal root ganglion cell

location= dorsal root ganglion structural class of neuron= pseudounipolar neuron functional class of neuron= sensory neuron

bipolar cell

location= special sense organs (retina) structural class of neuron= bipolar neuron functional class of neuron= special sensory neuron

on the basis of function, what kind of neuron has its cell body in the dorsal root ganglion?

sensory neuron

on what specific tissue do the axons whose cell bodies lie in the anterior gray horn terminate?

skeletal muscle tissue

where can bipolar neurons only be found?

special senses (retina)

name three specific examples of multipolar neurons and state where each is found in the body.

1. purkinje cells= cerebellum 2. anterior horn cell= anterior gray horn of spinal cord 3. pyramidal cell= cerebellum

by what pathway do the axons arising from the cells in the anterior gray horn leave the spinal cord?

anterior nerve root

what specific kind of cell lies in the lateral gray horn?

autonomic nervous system

on the basis of function, what kind of neuron has its cell body in the anterior gray horn?

motor neuron

on the basis of its shape, what kind of neuron has its cell body in the anterior gray horn?

multipolar neuron

on the basis of its shape, what kind of neuron joins sensory neurons to motor neurons?

multipolar neurons

on the basis of function, what kind of neuron (functional class) pass through the dorsal root?

sensory neuron

white matter

primarily contains= myelinated axons in cerebellum= arbor vitae in cerebrum= peduncles/capsules in spinal cord= tracts/white columns in PNS= nerves

gray matter

primarily contains= neuronal cell bodies/dendrites in cerebellum= cerebellar cortex in cerebrum= cerebellar cortex/deep nuclei in spinal cord= gray horns in PNS= ganglia (ganglion)

on the basis of shape (structural), what kind of neuron has its cell body in the dorsal root ganglion?

pseudounipolar neuron

on the basis of shape, what kind of neuron (structural class) passes through the dorsal root?

pseudounipolar neuron
