The axon of a neuron conducts electrical impulses away from the cell body. This is easy to remember because axon starts with an "a" for away.

What structure insulates neurons?

The myelin sheath is a structure that insulates neurons. It is made up of specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. The myelin sheath helps to increase the speed and efficiency of nerve impulse conduction along the axon.


Do sodium ions move to inside of neuron in a nerve impulse?

No. Three sodium ions are pumped out of the neuron by the sodium-potassium pump and two potassium ions enter the cell. This way you maintain a slightly negative charge just inside the cell membrane.


Why is the chemical synapses be release when a neural impulse reaches the end of an axon?

Chemical synapses release neurotransmitters when a neural impulse reaches the end of an axon to transmit information to the next neuron. This release of neurotransmitters allows for communication between neurons and helps propagate the neural impulse across the synaptic gap to continue the signal.


How does electricity affect the functioning of a neuron?

Electricity excites neurons. This happens because neuronal membranes are population with special type of protein called 'voltage-sensitive ion channels'. These become more permeable to specific ions with electrical current and as a result the cell will become metabolically more active.


What us synapse?

synapse are the microscopic gapes between the neurons where helps in passing of the chemicals from one neuron to other. A small amont of chemical substance is released from one neuron into the synapse and this chem. substance changes to electrical impluses and enters the dentrites of the other neuron.

What is a neuron identify the parts of the neuron and their functions?

there's the axon (the nerve) the electrical impulse goes down that and covering the axon is the myelin sheath, otherwise known as a fatty sheath which insulates and helps make the electrical impulse go faster. In between each myelin sheath there are synapses (gaps between each one) and the impulse has to cross the gap so neurotransmitters are released which bind to receptors on the other side creating another electrical impulse which makes it travel even faster.


What is the value of the connective nerve tissue wrapping found in nerve?

The myilen sheath helps conduct the nerve impulse kind of like water and electricity.


Why is the chemical synapses be release when a neural impulse reaches the end of an axon?

Chemical synapses release neurotransmitters when a neural impulse reaches the end of an axon to transmit information to the next neuron. This release of neurotransmitters allows for communication between neurons and helps propagate the neural impulse across the synaptic gap to continue the signal.


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 cell maintains homeostasis?

Homeostasis requires many different types of cells but the main cell that ensures that homeostasis is maintained is the nerve cell which forms your sensory neuron this helps by sending a nerve impulse to the hypothalamus of your brain or the islets of langerhan in the pancreas this nerve impulse helps send a message to the stated parts of your body telling them to take corrective measures to stabilize your body's internal environment


How does the myelin sheath help to carry nerve signals efficiently?

The myelin sheath acts as an insulating layer around the axon of a neuron, which helps to speed up the nerve impulse by allowing it to jump from one node of Ranvier to another. This process, known as saltatory conduction, allows the nerve signal to travel faster and more efficiently along the neuron.


I am a cell. I am long and thin. I reach all the way from the brain to the tip of a finger. I have a special coat of fat that helps me do my job. My job is to send electrical signals from one part of?

It sounds like you are a neuron, specifically a motor neuron. Motor neurons are long and thin cells that transmit electrical signals from the brain to muscles to control movement. The special coat of fat you mentioned is likely the myelin sheath, which helps conduct signals more efficiently along the neuron's axon.


What is synapses?

A synapse is a small gap at the end of a neuron that allows information to pass from one neuron to the next.


What is the function of nissl granules in human neuron?

Nissl granules are responsible for protein synthesis within neurons. They contain ribosomes and rough endoplasmic reticulum, which generate the proteins needed for the neuron's structure and function. This helps in maintaining the neuron's health and allows for neurotransmitters to be produced.
