What is the function of the PNS?
The peripheral nervous system, or PNS, conveys nerve impulses from your receptors to the central nervous system, or CNS. They also will convey nerve impulses from the CNS to your effector organs, typically a muscle or gland.
What neuron carries impulses from receptors to the central nervous system?
Neurons that convey sensory information are called 'sensory neurons' or "afferent neurones"
What afferent neurons convey information?
Afferent neurons carry sensory information in the form of nerve impulses to the central nervous system. Efferent/motor neurons carry commands to effectors such as muscles and glands.
What is the function of dendrons?
the function of a Dendron is to convey electrical impulses towards the cell body.
What is Neurons that convey impulses from the CNS to muscles or glands are what?
Interneurons
What is the function of the Vestibulospinal?
to convey impulses of equilibrium to anterior horn cells of spinal cord
What is the function of white mater in the spinal cord?
White and grey matter are essentially made up of bundles of nerve fibers (called neurons) that convey nerve impulses between the peripheral nervous system and the central nervous system. The major difference between white and gray matter within the spinal cord is that white matter is primarily composed of myelinated nerve fibers, while the nerve fibers of gray matter are not. Myelinated nerve cells tremendously increase the speed at which the action potential (nerve impulse) moves along the neurons axon. The job of the neurons that make up white matter is to either convey an action potential from a sensory receptor to the central nervous system, or, from the central nervous system out to an effector (such as a muscle or tissue). These neurons are called sensory neurons and motor neurons respectively. Gray matter consists of unmyelinated neurons, called interneurons. Their main duty is to provide communication between the peripheral and central nervous systems. Think of interneurons as a bridge linking two regions together. For unmyelinated neurons, the speed at which an action potential can propagate down the cell's axon is far less than that of the myelinated neurons of white matter.
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 is a long nerve fiber that convey electrical impulses to other cells is called a?
A long nerve fiber that conveys electrical impulses to other cells is called an axon.
How neurons transmit electro chemical impluses to the brain?
When nerve cells or neurons are stimulated they undergo chemical changes which make little waves of electricity or nerve impulses. These are based mainly on the movement of positively charged sodium and potassium ions through the neurons cell membrane.When the impulses reach a junction-synapse-they trigger the release of chemicals called neurotransmitters. These then cross the synapse and stimulate the receiving neuron to fire impules of their own. Dendrites collect nerve impulses and Axons convey impulses away from cell.
What is the comparison between the nervous system and an airmail system?
They both convey messages or information relatively quickly.
What is the main function of a motor neuron?
The function is to catch/take impulses from the central nervous system and send it to muscles and glands
