What are neurons that carry impulses?
Neurotransmitters -- like Dopamine, Epinephrine, Serotonin, Norepinephrine -- carry nerve impulses (action potentials) between neurons. More simply -- chemicals are released… into the synapse that may start another nerve impulse in the downstream neuron.
The axon of the neurone carries the impulse away from the cell body. The axon of the neurone carries the impulse away from the cell body.
Afferent neurons (sensory)
A motor neuron.
Nerves that only carry impulses away from the central nervous system (CNS) are called: Motor Nerves
There are two ways in which an electrical impulse may be carried from one neuron to another. These junctions are called synapses. In a chemical synapse, the electrical impulse… arrives at the presynaptic membrane and this triggers the release of neurotransmitter molecules from vesicles out into the synaptic cleft (the space between the two neurons). An example of a very common neurotransmitter in the brain is glutamate. The neurotransmitter molecules bind to receptors on the postsynaptic membrane and can either directly open ion channels, or cause a chain of biochemical events that result in the opening of ion channels. In turn, the opening of ion channels in the postsynaptic membrane causes the voltage across the membrane to change and thus the electrical impulse proceeds down the postsynaptic neuron. Depending on the neurotransmitter and ion channels in the postsynaptic membrane, the first impulse could also inhibit the second neuron from propagating electrical impulses. The chemical synapse is much more common than the electrical synapse, described below. In an electrical synapse, the membranes of the two neurons are very close together and specific proteins form channels between them. This allows ions to move between the cells and the electrical impulse can thus move from one neuron to the next.
Neurons that convey sensory information are called 'sensory neurons' or "afferent neurones"
It's not a specific neuron. The general name is "motor neurons" or sometimes "efferent neurons" ("efferent" means they send signals out from the central nervous system).
The part of the neuron that carries impulses towards the cell body is called the dendrite.
The functional and structural unit of the nervous system for fast communication are called neurons. A neuron is made of cell body with extensions which are the axons and d…endrites that carry impulses.
