Myelin covers the axon to protect it and help messages travel faster. Two types of cells produce myelin, the oligodendrocytes in the CNS and Schwann cells in the PNS.

The specialized cells of the PNS that are surrounded by a basement membrane that is capable of forming a regeneration tube through which a severed peripheral axon can regrow are the?
Schwann cells
What does not belong axon terminal synaptic knob bouton axon collateral?
axon collateral
What are the 3 main structures of a neuron?
Dendrites, Axon, Axon Terminal, and Cell Body
What part of a neuron attaches the cell body to the axon?
axon hillock
Which region of the cell body from which the axon originates?
The axon (in motor neurons) begins just distal to a slightly enlarged cell body structure called the axon hillock.
What A wave pattern travels down the length of the axon of a cell.?
A wave pattern travels down the length of the axon of a nerve cell. A nerve cell, also called a neuron, is a specialized cell that transmits nerve impulses.
A wave pattern travels down the length of the axon of what kind of cell?
A wave pattern travels down the length of the axon of a nerve cell. A nerve cell, also called a neuron, is a specialized cell that transmits nerve impulses.
The specialized cells of the PNS that are surrounded by a basement membrane that is capable of forming a regeneration tube through which a severed peripheral axon can regrow are the?
Schwann cells
What region of the cell secretes neurotransmitters?
an axon terminal
What does not belong axon terminal synaptic knob bouton axon collateral?
axon collateral
What structure contains the cell body (soma) of a sensory nerve receiving sensory information from the skin?
A typical neuron possesses a cell body called soma, dendrites and axon. The sensory nerve cells receiving information from the skin are pseudounipolar cells having two axon. One axon extends centrally towards the spinal cord and the other axon extends towards the skin. The soma of these nerve cells having neurofilaments of specialized proteins receive sensory information through electric and chemical signals called neurotransmitters.A typical neuron possesses a cell body called soma, dendrites and axon.

The axon is made up of?
what is the axon made of
The axon is connected to the soma by the?
axon hillock
What are the parts of nerve or neurons?
A neuron is a nerve cell, so it has all the parts of an animal cell, plus some specialized parts: axon, dendrites, and perhaps a myelin sheath for insulation.
What is a axon hillock?
An axon hillock is a special cell body that connects an axon to a neuron. It is the last place where propagated membrane potentials are transmitted to the axon.
What are the 3 main structures of a neuron?
Dendrites, Axon, Axon Terminal, and Cell Body
Is and axon bulb and an axon hillock the same thing?
axon hillock = where cell body meets the axon axon bulb = end of the axon...lies very close to the dendrites of another neuron so impulses can pass over the synapse. AP Biology student *
