Microscopic fiber that carries the nervous impulse along nerve cell?
Wiki User
∙ 13y ago
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.

∙ 9y agoThe long nerve fiber that carries impulses from one nerve cell to another and to other cells such as glands and muscles is called an axon.
Wiki User
∙ 12y agoIt is the axon. The axon is a long fiber that carries impulses away from the cell body of one nerve cell and carries the impulse towards the cell body of the receiving cell.

What is a disadvantage of unmyelinated nervous tissue when compared to myelinated tissue?
Unmyelinated tissue is substantially slower in conducting impulses along the axon. With myelinated axons, the action potential (impulse) jumps from node to node greatly increasing the speed of the impulse.
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.
Ependymal cells show irritability and conductivity?
NO, that is FALSE. The answer is NEURONS.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.
If a motor neuron in the body were stimulated by an electrode placed about midpoint along the length of the axon?
the impulse would spread bidirectionally
Where are action potentials regenerated as they propagate along a myelinated axon?
First at the axon hillock where the neural impulse is initially triggered, and then at the nodes of Ranvier as the impulse continues to travel along the axon.(Note that the impulse travels as electrotonic conduction between the nodes of Ranvier, underneath the glial cells which myelinate the axon.)
Microscopic fiber that carries the nervous impulse along a nerve cell?
axon
What are mircroscopic fiber that carries the nervous impulse along a nerve cell?
axon
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 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 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 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.
Ependymal cells show irritability and conductivity?
NO, that is FALSE. The answer is NEURONS.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.

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.
What is the direction of impulse in a neuron?
A nerve impulse travels toward the actual nucleus itself to pass information.
