Axons and dendrites usually are found in cells of which tissue?
nervous tissue
Groups of axons and dendrites in the PNS are called?
A group of axons in the CNS is most likely referring to the tracts of neurons that are found in the spinal cord.
Dendrites found on unipolar neurons are part of what?
They are sensory neurons. :)
How many axons does each neuron have?
Most neurons contain one axon. There have never been more than one found. However, some neurons contain no axon at all.
What are the threadlike extensions of a neuron called?
I believe it's Dendrites..but not for sure..but I'm working on physiology for the American school and I found this on page 400 if you're working on the same thing

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.
Groups of axons and dendrites in the PNS are called?
A group of axons in the CNS is most likely referring to the tracts of neurons that are found in the spinal cord.
Which structures pertain to neurons?
Synapses, dendrites, dendritic spines (bumps on dendrites where synapses are often found), dendritic arbors (tree-like projections of dendrites), somas (body of neuron), axon hillocks (where a summation of input impulses may initiate an action potential or spike), axons, myelin sheaths (on myelinated axons), and axon terminals (containing vesicles of neurotransmitters).
Are dendrites and axons both armlike processes that extend from cell bodies?
Yes, it is true. Dendrites: Arm-like processes that extend from the cell body of all neurons which receive signals. They are short, tapering, and have branching extensions and are usually found close to the cell body. Dendrites are unmyelinated (slow conductors). Axons: Are single arm-like process that extends from the cell body of all neurons which generate and transmit nerve impulses. They can be long (up to ~ 1 meter) or short with diffuse branching at the end. Axons are myelinated (fast conductors).
Where are Receptor sites on a neuron primarily found?
dendrites only
Dendrites found on unipolar neurons are part of what?
They are sensory neurons. :)
Where are dendrites found?
Parts of neurons, which are found in the brain.
How many axons does each neuron have?
Most neurons contain one axon. There have never been more than one found. However, some neurons contain no axon at all.
What makes brain matter white?
The myelin sheaths found on axons in the brain ("myelinated axons") gives most brain tissue a white color (= "white matter"). The grey, unmyelinated sell bodies, or "soma," of these axons reside in areas of the brain commonly referred to as "grey matter." Ben
Nodes of ranvier are found in?
In invertebrate nerves, axons and dendrites are uncovered, and signal transfer is a fairly slow process. In vertebrates, many axons and dendrites are covered in myelin, a fatty substance which insulates the nerves and speeds up conduction. However, for signal conduction to occur, ions have to be able to move in and out of the nerve along its length to transmit the impulse. Since ions can't diffuse through myelin, they have to go through the nodes of Ranvier. This is called saltatory conduct.
