What type of conduction takes in unmyelinated axon?
continuous
What type of conduction takes place in an unmyelinated axons?
Continuous conduction.
What is impulse propagation?
It is the traveling of the electrical signal down the length of a neuron.
Which neuron is never myelinated?
Neurons that do not have a myelin sheath must use continuous conduction, which is slower. These are the smaller axons of the CNS, as well as some types of fine sensory fibers, such as olfactory nerves.
Do small unmyelinated axon travel signal faster than large unmyelinated axon?
no
Why is the conduction of impulses slow in autonomic nervous system?
Because there is no need for a fast transmission, in most cases, of the chemical messengers (hormones). Therefore, the nerve cells are unmyelinated and send their signal in a continuous transmission.
What has the author Omar Siddiqui written?
Omar Siddiqui has written: 'Resonance-cone propagation in continuous transmission-line grids and microwave applications'
Does impulse travel faster along myelinated neuron?
Yes, impulses travel faster in myelinated axon rather than in unmyelinated. It is mostly due to nodes of Ranvier. Instead of travel along the axon, in myelinated axon impulses "jump" from node to node. Also there are two types of myelinated axons: type A and type B. (Type C in unmyelinated axon.) Type A is the fastest among all of them.
Gray matter in the spinal cord is mostly?
unmyelinated axons.
What connective tissue cover myelinated or unmyelinated axons?
The connective tissue that covers unmyelinated and myelinated axons is called endoneurium.
Can a myelinated axon have a larger diameter than an unmyelinated axon?
Unmyelinated fibers typically have smaller diameters than myelinated fibers.
What generate and transmit nerve impulse?
A sensory stimulus can generate a neural impulse, as can repeated or multiple inputs of neural signals from other neurons.A neural signal is transmitted from one neuron to anotheracross a synapse via chemicals called neurotransmitters, and a neural impulse is transmitted along an axon of a neuron by either an action potential (in an unmyelinated axon) or by saltatory conduction (in a myelinated axon).
