What else can I help you with?
Once transmission of an impulse is started it always?
Once the electrical, within-neuron signal starts, it will continue to the terminal end of the neuron in an all-or-none fashion, unless influenced by another neuron. For example, an inhibitory (e.g., GABA-ergic) neuron can stop or weaken the electrical signal in the first neuron (e.g., by increasing chloride influx). Once the neuron releases its transmitter, though, the transmitter has been released; however, that chemical signal can be modified either post- or pre-synaptically by action at the receptors. A+ students: the answer is completes the journey
List and define the three types of synapses?
chemical synapse operation at the transmitter Electrical Ionic Flow. At the synapse the following things happen Divergence and synaptic neuron
What major mineral is required for transmission of nerve impulses?
neuro transmitter is essential for the transmission of nerve impulses in nerve fibres.it is a chemical which is present in the axon terminal bulb(ending of a neuron).
Transmission of the nerve message within the neuron is in nature?
The transmission of nerve messages within a neuron is primarily electrical in nature. It involves the movement of ions, such as sodium and potassium, across the cell membrane, resulting in a change in the neuron's membrane potential. This process, known as an action potential, allows for the rapid and efficient relay of information within the nervous system.
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
What is flow transmitter?
pressure transmitter
What is the difference between transmitter and smart transmitter?
They are at different levels. The transmitter will help you to get started by the smart transmitter will help you with more advanced problems.
Where is the neuron?
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
What effect do neurotransmitters from one neuron have on the next neuron?
Neurotransmitters released from one neuron can either excite or inhibit the next neuron. Excitatory neurotransmitters make the receiving neuron more likely to fire an action potential, while inhibitory neurotransmitters make it less likely. This process allows for communication and coordination between neurons in the nervous system.
Why is a neuron called an interneuron?
A neuron is called a inter-neuron because that specific neuron takes impulse from one neuron to a next neuron. For example your sensory neuron sends a impulse that you had felt a hot object. It goes through the spine to a inter-neuron to a motor neuron (this processes is called a reflex). Then the motor neuron tells your muscles in your hand to move
Define relay neuron?
a relay neuron is the neuron that picks up the message from the sensory neuron and delivers it to the motor neuron in the spinal cord or the brain
Where is the transmitter?
transmitter is a device that creates the message that is to be transmitted.
