The speed of nerve impulse transmission through the axon of a sensory neuron will be quickest in?

I'm guessing; "myelinated nerve fibres" contrary to the much slower "non-myelinated nerve fibres"


Neurons which are wrapped in a fatty membrane are?

Neurons wrapped in a fatty membrane are called myelinated neurons. The fatty substance that wraps around the neuron is called myelin, and it helps to insulate and speed up the transmission of electrical impulses along the neuron's axon. Myelinated neurons are found in the central and peripheral nervous system.


Are muscles and glands myelinated?

Muscles and glands are not myelinated. It is the axon of a neuron that is myelinated. The myelin forms a layer called myelin sheath that makes the nervous system function properly.


Are the nodes of ranvier only found on myelinated peripheral neuron processes?

Yes.


What is the output structure of a neuron?

The axon is the output structure of a nerve cell. Many times it is myelinated like an electrical wire.


What affects nerve impulse speed?

Nerve impulse speed is affected by the diameter of the nerve fiber (larger fibers conduct faster), the presence of myelin sheath (myelinated fibers conduct faster), and temperature (warmer temperatures enhance conduction speed). Additionally, the refractory period of the neuron and the strength of the stimulus can also influence nerve impulse speed.


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.


What part of the neuron is sometimes myelinated?

Myelin Sheath is basically fat-containing cells that insulates the neurons from any electric impulses that travel along the nerves and makes sure that the impulses do not jump between close nerves


Are ll sensory and motor neurones myelinated in organisms?

Not all sensory and motor neurons are myelinated; it depends on the type of neuron and its function. Myelinated neurons, which have a protective myelin sheath, facilitate faster signal transmission and are commonly found in motor neurons and some sensory neurons, such as those involved in touch and proprioception. However, unmyelinated neurons also exist, particularly in systems where speed is less critical, such as certain pain and temperature sensory pathways. Thus, the presence of myelination varies among different types of neurons in organisms.


Neurons can conduct messages faster if they have?

myelinated axons. Myelin is a fatty substance that wraps around the axon, acting as an insulator to increase the speed of electrical impulses traveling along the neuron. This allows for faster and more efficient communication within the nervous system.


Would conduction speed of a nerve fiber be the fastest in a large or small myelinated fiber?

The conduction speed of a nerve fiber is fastest in large myelinated fibers. This is because myelin acts as an insulator, allowing for faster propagation of the action potential by saltatory conduction in large fibers compared to small unmyelinated fibers.
