which type of neuron conducts impulses faster course hero

Full Answer

Which type of neuron conducts impulses faster?

Neurons with myelin (or myelinated neurons) conduct impulses much faster than those without myelin.

Which type of neuron conducts information away from the central nervous system out to effectors in the periphery?

Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands. Efferent neurons usually have short dendrites and long axons.

What type of cells function to transmit information?

Which cell type functions to transmit information? Neurons: Transmit nerve signal between parts of the nervous system.

What structure serves as the main receptive region of a neuron?

They contain many of organelles found in the cell body, which perform the same metabolic functions. Dendrites make up most of the receptive zone of a neuron and can detect specific changes in the surrounding environment (stimuli). neurotransmitter molecules released by the axons of nearby neurons.

What is multipolar neuron?

Multipolar neurons are the most common types of neurons in the CNS; they form the autonomic ganglia. They possess a single axon with several symmetrically radiating dendrites. Some neurons have multiple axons or lack axons all together.

Which type of neuron conducts the impulse from the spinal cord to an effector?

c) motor or efferent neuron: - conducts nerve impulses from the brain or spinal cord to the effector organ (muscles or glands).

Which type of neuron conducts impulses faster quizlet?

Large-diameter nerve fibers conduct impulses much faster than small-diameter fibers. A postsynaptic potential is a graded potential that is the result of a neurotransmitter released into the synapse between two neurons. In myelinated axons the voltage-regulated sodium channels are concentrated at the nodes of Ranvier.

How fast do neurons transmit information?

Neurons transmit an electrochemical signal called the action potential. These signals travel down a part of the neuron called the axon, which is like a wire that carries the signal to other nerve cells. On average a nerve cell sends a signal at about 50 meters per second, which is over 100 miles an hour!

Which neuron carries impulses between neurons?

Relay neuronesRelay neurones carry nerve impulses within the central nervous system. Motor neurones carry nerve impulses away from the central nervous system. The neurone ends in either a muscle or gland, which are effectors.

Which type of axon transmits a nerve impulse at the highest rate?

The increased diameter of the myelinated axons allows for the transmission of impulses at a faster rate.

Which factors influence the speed of nerve signal conduction?

The speed is affected by 3 factors:Temperature - The higher the temperature, the faster the speed. ... Axon diameter - The larger the diameter, the faster the speed. ... Myelin sheath - Only vertebrates have a myelin sheath surrounding their neurones.

What do interneurons do?

Interneurons. As the name suggests, interneurons are the ones in between - they connect spinal motor and sensory neurons. As well as transferring signals between sensory and motor neurons, interneurons can also communicate with each other, forming circuits of various complexity.
