This is a very long and hard 1-2 weeks of worth of work and studying to understand but ill try my best.
A neuron consists of the following structures in the following order:dendrites, soma, axon, myelin sheath, and the axon terminal. Then the synapse. The dendrites on a cell recieve a chemical signal potential from recieved neurotransmitters. The potential changes the polarity within the soma by stimulating and opening the sodium ion channels. The cell either hyperpolarizes or depolarizes If it depolarizes an electrical impulse is sent down the axon. The axon is protected by the myelin sheath. The myelin sheath increases the conductivity of the axon allowing the electrical impulse to carry all the way down the axon. When it reaches the end of the axon it travels into the axon terminal, and the terminal buds. The vesicle sacs are then stimulated, which releases neurotransmitters into the synapse. The neurotransmitters then float across the synapse and stimulate the dendrites of the postsynaptic cell, starting the whole process over again with that cell. When enough neurotransmitters have been released, the autoreceptor on the presynaptic cell will be stimulated. Then the neurotrasmitters reuptake into the terminal buds, where they will either be returned to the vesicle sacs for use at a later time (next time the neuron fires), or else they will be destroyed by the MAO enzyme
This is a very simplified version of it and will most likely confuse you but in this limited amout of space it about the best i can do. sorry.
What else can I help you with?
What is the name of the cells in which nerve signals travel through?
Neurones
What cells have the ability to respond to stimuli by generating signals such as action potentials?
Nerve cells or neurons have the ability to respond to stimuli by generating signals such as action potentials. These signals travel along the nerve cells to communicate information within the nervous system.
What is the difference between nerve signals and hormones?
Nerve signals are electrical impulses that travel through neurons to transmit information quickly within the body, while hormones are chemical messengers released by glands into the bloodstream to regulate various bodily functions over a longer period of time. Nerve signals are fast-acting and localized, while hormones are slower-acting and can have widespread effects throughout the body.
What is an excitable nerve cell that sends electrical signals?
A neuron is an excitable nerve cell that sends electrical signals when stimulated
For communitcating visual signals to the brain which is the nerves is responsible?
The optic nerve is primarily responsible for communicating visual signals from the retina in the eye to the brain. It transmits the electrical impulses generated by photoreceptor cells in response to light, allowing the brain to process and interpret visual information. The signals travel from the optic nerve to the visual cortex, where they are further analyzed and understood.
What is the name of the cells in which nerve signals travel through?
Neurones
What is a short thick nerve throgh which signals travel to the brain from the eye called?
optic nerve
How fast can nerve signals travel?
Nerve signals can travel at speeds ranging from 1 meter per second to more than 100 meters per second. The speed depends on various factors such as the type of nerve fiber, myelination, and the presence of nodes of Ranvier.
How are neurotransmitters different from the impulse that travel along the bodies of nerve cells?
Neurotransmitters are chemicals that transmit signals between nerve cells at synapses, while impulses refer to the electrical signals that travel along the nerve cells themselves. Neurotransmitters bridge the gap between two nerve cells, whereas impulses are the electrical messages that travel along the length of a nerve cell.
How are neurotransmitters different from the impulses that travel along the bodies of nerve cells?
no you give an answer im the one that asked the question
What are tiny pulses of electricity that move along a nerve fiber?
Nerve signals Thats what my crossword was.
What cells have the ability to respond to stimuli by generating signals such as action potentials?
Nerve cells or neurons have the ability to respond to stimuli by generating signals such as action potentials. These signals travel along the nerve cells to communicate information within the nervous system.
These cover the axonin order to make nerve signals faster?
Some axons have an insulating coating, called the fatty myelin sheath, to make signals travel faster.
Which nerve conveys parasympathetic signals to the heart?
The Vegal Nerve conveys parasympathetic signals to the heart
How fast nerve signals travel to the brain per sec?
Nerve speeds vary, BUT on average move 115-197 ft/sec (35-60 m/sec).
Nerve impulse consists of a wave of moving away from a point of stimulation?
Nerve impulses are electrical signals that travel along the length of a nerve cell. These signals are initiated by the movement of ions across the cell membrane, creating a wave of depolarization that propagates down the length of the nerve fiber. This depolarization causes the nerve cell to fire, transmitting the signal to other cells.
How fast do nerves impulses travel?
Nerve impulses travel through nerve fibers via a action potential and the speed at which the impulse travels depends on the type of nerve fibre. This can range from 100m/s in the case of touch to 20-30 m/s when you're thinking.
