There are several key parts to a neuron: dendrites, which receive input, cell body or soma, where the electrical impulses sum, axon, the structure along which the action potential is propagated, and the terminal buttons which release neurotransmitters into the synapse between two neurons.
What else can I help you with?
What is the part of nerve cell transmit messagefrom the brain to the different part of the body?
Motor neurone send message from the brain to the affector
What does a Neurone cell do?
A neurone is a nerve cell, they allow you to feel pain.
What is a relay nerve cells?
Interneuron (relay neurone) Relays messages from sensory neurone to motor neurone. which make up the brain and spinal cord
What is acetylcholen?
Acetylcholine (ACh) is an exitatory neurotransmitter. This means it is released from the synapse of the neurone and promotes the continuation of the AP in the next neurone instead of inhibiting it. ACh is part of the peripheral nervous system and is not very prominent in the central nervous system.
What is the function of the cell bodies of the neurone?
The main part of the neuron, containing the nucleus and other organelles and serving as the site of the cell's metabolic reactions; processes input from the dendrites and if input is large enough relays to the axon, where an impulse is initiated.
What is the name of a neuron that transmits neural impulse from the sensory neuron to the motor neuron?
A relay neurone passes impulses from a sensory neurone to a motor neurone.
Is neurone a tissue?
no...
Are there any diseases or disorders that affect the diaphragm?
diaphragm cancer, motor neurone diaphragm cancer, motor neurone
Is a neurone an organ or tissue?
A neuron is a type of cell, not an organ or tissue. Neurons are the basic building blocks of the nervous system and work together to transmit electrical and chemical signals in the body.
Motor neurone disease is infective?
Motor neurone disease is not an infectious disease. It is a progressive neurological condition that affects the nerves in the brain and spinal cord that control movement. The exact cause of motor neurone disease is not fully understood.
Is neurone a tissue a organ or a cell?
it is a cell
Numerous nerve impulses arriving at a synapse at the same time exert a cumulative effect?
Kind of. Each neurone can have thousands of inputs from other neurones arriving at the same time. It all depends on the types of signal arriving from the other neurones. There are 2 types of incoming signal; 1. Excitatory Post-synaptic potentials (EPSPs) - These inputs depolarise the neurone (bring the negative voltage of the neurone closer to 0mV). 2.Inhibitory Post-synaptic potentials (IPSPs) - These inputs hyperpolarise the cell (make the neurone voltage more negative). Some of the inputs coming to the neurone will be EPSPs, some IPSPs. If all the inputs come in and there are more EPSPs then the neurone will depolarise. If the neurone depolarises to the firing threshold (around -40mV) then an action potential will be propagated and the neurone will transmit the message to the next neurone in the chain. If the majority of the inputs are IPSPs then the neurone will hyperpolarise and will not fire. If there are more EPSPs than IPSPs but the neurone still doesn't depolarise enough to reach the firing threshold then the neurone will not fire.
