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 changes light to an impulse in the eye?
When light enters the eye, it passes through the cornea, then the lens, and ultimately reaches the retina at the back of the eye. Here, light triggers a chemical reaction in the cells of the retina called photoreceptors, specifically in rods and cones, which convert the light into electrical impulses that are then transmitted to the brain via the optic nerve.
What is the conducting unit of the nerve tissue?
The axon is the conducting part of the neuron. It conducts the impulse from the cell body to the terminals, where ion channels open in response to the impulse, mediators are activated, neurotransmitter crosses synapse and attaches at the post-synaptic membrane, opening the ion channels there and depolarizing the cell, and propagating the impulse towards another cell body via the post-synaptic cell's axon.
When you want to move your arm your brain sends a message where does the message go?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineEach nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.a nerve impulse travels along the neuron in the form of electrical and chemical signals.Acetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction.
What cells are responsible for the myelination of neurons in the cns?
In the central nervous system (CNS), oligodendrocytes are responsible for myelinating neurons. These specialized cells form the myelin sheath around axons, which helps in the transmission of nerve signals.
What nervous system controles the nerves that branch out from the central nervous system?
The CNS connects via the spinal cord to the PNS (peripheral nervous system).
What is the portion of the neuron that accepts incoming impulses?
The receptor is the part of the neuron (usually a dendrite) that detects a stimulus. Dendrites are extensions of the main cellular body of the neuron called the soma; the impulse is passed on to another neuron at the other end, which is called the axon. Neurons transmit impulses to each other via electro-chemical connections to each other that are known as synapses.
Sensory neurons enter the spinal cord via what root?
ventral root yo
What steps involved in transmitting the impulse from one neuron to another and then to the muscle fiber?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineEach nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.a nerve impulse travels along the neuron in the form of electrical and chemical signals.Acetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
How does vibration cause sound?
Vibrations alter the density of the air (or other medium) around them. They do this as a wave. When the wave reaches a person's eardrum it makes it vibrate to the rhythm of the vibration. This is conducted to the brain via an electrical impulse and we hear it as sound.
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 must be present for a nerve impulse to begin?
each nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.a nerve impulse travels along the neuron in the form of electrical and chemical signals.Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction.
How is an impulse communicated from nerve cell to nerve cell?
Via chemical messangers that cross the synapse.
If a batter reaches base via a bunt is it counted as a hit?
It is.

Macroscopic neurology - trace impulse macroscopically through the nerveous system from the brain to the muscle?

What is the function of the dentrites?
Dendrites are attaches to the axon terminals of other neurons. The nerve impulse travel from other neurons into the corresponding neuron via dendrites.
