Nervous System Histology
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
