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 are electrical junctions in the human body?
Electrical junctions in the human body are where the axons of nerves (singly called neurons) send a chemical to the dendrite(s) of nearby neuron(s), said chemical creating a weak electrical current in the next neuron. These neuron to neuron junctions are called, "Synapses".
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 carries messages away from neuron?
The axons.
When medication is used what part of the neuron is involve?
Axons
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.
Spinal nerve roots which contain only motor neuron axons?
the what? root of a spinal nerve consists of motor neuron axons
What is a tiny branching thread-like structure found in neurons?
There are two possible answers - axons or dendrites. Axons carry action potentials away from the neuron, while dendrites receive action potentials.
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.
The axons of which of these neuron layers form the optic nerves?
Ganglion Cells
