What is the part of the neuron that carries messages?
Dendrites carry messages to a cell body of a neuron.
Does parasympathetic have postganglionic axons secrete norepinephrine?
no, not all postganglionic sympathetic fibre neuron secrete NE
Which type of cell produces the myelin covering around the axon of a neuron?
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.
What are the two kinds of branches that extend from the cell body of a neuron?
Terminal branches (aka end brushes) are at the end of a Motor Nerve (aka Efferent Nerve) and are in very close proximity to the muscle fibers.
What is the part of the neuron that carries signals and transmits them to other neurons?
The smaller, receiving, head end of a neuron is called the dendrite. This transmogrifies first into the nucleus containing cell body and then into the multi-branched transmission arms of the axon. Axons from the spine to the foot are up to a meter in length.
Can a neuron have multiple axons?
No, each neuron has only one axon, but has multiple dendrites so it can receive information from multiple axons from other multiple neurons.
Axons and dendrites is another word for?
Axons are the output element of a neuron, and dendrites are the input elements of a neuron.
What are the parts of neuron and its function?
The three main parts of a neuron are the soma (cell body), the axons, the long trailing output of a neuron and the dendrite or dendritic tree. Almost all neurons have axons, but not all axons have a dendritic tree.

What portion a neuron conducts nerve impulses away from the neuron?
axons
What is the highest number of axons a neuron can have?
A neuron can have at most one axon. However, an axon can branch - sometimes many times.
What carries messages away from neuron?
The axons.
When medication is used what part of the neuron is involve?
Axons
Spinal nerve roots which contain only motor neuron axons?
the what? root of a spinal nerve consists of motor neuron axons
What are the two kinds of branches that extend from the cell body of a neuron what does each do?
The ones carrying the input are the dendrites, the ones carrying the output are the axons.
Where do first order sensory neuron axons reside?
In a ganglion.
What is the part of the neuron that carries messages?
Dendrites carry messages to a cell body of a neuron.
