What carries impulses from the skin to the central nervous system?
A pseudo-unipolar neuron referred to as an afferent neuron carries a sensory impulse to the spinal cord, which is part of the central nervous system.A pseudo-unipolar neuron has one axon which comes from the cell body (soma) and then splits into two branches, the peripheral axonal branch which carries the impulse from the skin, and the central axonal branch which carries the impulse to the spinal cord; it has no dendrites, which distinguishes it from a bipolar neuron.The impulse moves along the peripheral branch and then to the central branch, skipping the soma.
What is the main function if the nerve cells?
A neurone is a collection of specialized cells, along with supporting cells (oligodendrocytes), that convey or carry an electrical impulse to or away from the central nervous system.
What wraps around larger axons?
Larger axons are typically wrapped with a fatty substance called myelin, which is produced by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system. Myelin serves as an insulating layer that helps to increase the speed and efficiency of nerve impulse conduction along the axon.
What is the membrane of a nerve cell is comprised of?
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
Is action potential essential for impulse propogation?
Yes, action potential is essential for the propagation of impulses in neurons. It is the electrical signal that travels along the axon of a neuron, allowing the communication of information within the nervous system.
What are mircroscopic fiber that carries the nervous impulse along a nerve cell?
axon

Microscopic fiber that carries the nervous impulse along nerve cell?
Some nerve cells have fibers that grow out of the cell, which are called axons. Axons allow a nerve cell to connect to distant parts of the body, so that cells in the brain can send messages to, and receive messages from a toe, for example, which might be six feet away from the brain. Other nerve cells just connect to their immediate neighboring nerve cells, and therefore do not require axons; they instead have smaller extensions called dendrites.
What is a nerve message called?
Well they are sent through the nervous system.
What is impulse in the nervous system?
electrical wave conducted along the nerve generated by the voltage difference across the cell membrane of the nerve cells.

What cells show irritability and conductivity?
Neurons are highly irritable or excitable(responsive to stimuli). When a neuron is adequately stimulated, an electrical impulse is generated and conducted along the length of its axon. This response, called the action potential or nerve impulse, is always the same, regardless of the source or type of stimulus, and it underlies virtually all functional activities of the nervous system.The answer is NEURONS.
What kind of neuron carries impulses from the spinal cord and brain?
The somatic nervous system, which is part of the peripheral nervous system, delivers motor and sensory information along the central nervous system- essentially connecting things like the skin nerves to the brain.
What is the membrane of a nerve cell is comprised of?
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
How nervous impulse travel in body and diagram?
Nervous impulses travel along neurons through a process called action potential, which occurs when a neuron is stimulated by an external signal. This stimulation causes sodium ions to flow into the neuron, leading to a rapid change in electrical charge that propagates along the axon to the synapse. At the synapse, neurotransmitters are released to transmit the signal to the next neuron. A simple diagram would illustrate a neuron with labeled parts: dendrites, cell body, axon, and synaptic terminal, showing the direction of impulse travel.
Is action potential essential for impulse propogation?
Yes, action potential is essential for the propagation of impulses in neurons. It is the electrical signal that travels along the axon of a neuron, allowing the communication of information within the nervous system.
