Nervous impulses travel along neurons through a process called action potential, which occurs when a neuron is stimulated by an external signal. This stimulation causes sodium ions to flow into the neuron, leading to a rapid change in electrical charge that propagates along the axon to the synapse. At the synapse, neurotransmitters are released to transmit the signal to the next neuron. A simple diagram would illustrate a neuron with labeled parts: dendrites, cell body, axon, and synaptic terminal, showing the direction of impulse travel.
What else can I help you with?
What are the subsystems of the autonomic nervous system?
The autonomic nervous system consists of the sympathetic nervous system, which prepares the body for fight or flight responses, and the parasympathetic nervous system, which promotes rest and digestion.
How fast does a nerve impulse travels?
It 200 miles per hour And it can probally be in meters too.
What part of the nervous system has the responsibility for carrying nerve impulse to and from the body?
The dendrites carry impulses to the neuron's cell body. The axon carries impulses away from the cell body.
What tissue type functions in impulse conduction?
Nervous tissue functions in impulse conduction. It consists of neurons that transmit electrical signals or impulses throughout the body. The specialized structure of neurons, including dendrites, axons, and synapses, enables them to rapidly transmit information.
What is the path that nervous impulse takes through the nervous system?
A nervous impulse begins in the dendrites of a neuron, travels through the cell body and axon, and then is passed on to the next neuron via a synapse. This sequence repeats until the impulse reaches its destination, such as a muscle or gland, where it triggers a response.
What is the branching fiber that is the first part of the neuron to receive a nervous system impulse called?
The branching fiber that is the first part of the neuron to receive a nervous system impulse is called a dendrite. Dendrites receive signals from other neurons or sensory receptors and transmit these signals to the cell body of the neuron. They play a crucial role in receiving and integrating incoming information in the nervous system.
Where do nerve impulses travel?
Nerve impulses travel up through nerves, into the spinal cord and into one of the different lobes of the brain depending on where the impulse comes from. For example, if the impulse comes from your ear, the impulse would travel to the temporal lobe.
What direction does nerve impulse travel?
Along a nerve cell, the impulse travels from the axon to the dendrites and then again to the axons through the synapse.
Microscopic fiber that carries the nervous impulse along a nerve cell?
The microscopic fiber that carries the nervous impulse along a nerve cell is called an axon. Axons are long, slender projections of a nerve cell that transmit electrical signals away from the cell body to other neurons, muscles, or glands. These signals, known as action potentials, travel down the axon through a process called depolarization and repolarization.
What are the names of the second and third laws of motion?
Newton's 2nd Law - Impulse and momentum Newtons third law - Free body diagram
What is the adaptive features of neurone on the central nervous system?
the neuron consist of the million short dendrites that receive electric impulse to the body cell, also the long axon that takes away the electric impulse away from the cell body and also it contain the myelin sheath that helps in contraction on axon to facilitate the quick transmission of the nerve impulse
What system controls all the parts of the body by sending impulse messages?
The nervous system controls all parts of the body by sending impulse messages. It is composed of the brain, spinal cord, and nerves that transmit signals to coordinate bodily functions and respond to internal and external stimuli.
