What chemicals are used to transmit impulses through the neurons?

∙ 12y ago
the transmission of a nerve impulse along a neuron from one end to the other occurs as a result of chemical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized that is there is a difference in electrical.

How is thinking a chemical change?
When you think, your body releases chemicals into the brain, those chemicals trigger neurons to go off and helps make decisions, emotions, and ideas pop up. When you are happy, for example, your body releases dopamine into your system and your brains neurons pick it up and translate the dopamine to an electrical charge firing through those neurons. If you think about it (no pun intended) a chemical change is described as a substance(s) changed to form another substance(s) with different properties, and also you cannot change the new substance(s) back through a physical change. I hoped this answered your question.
Does heat transmit readily through a molecule?
Yes, normally it does.
Does chemicals from cigarette smoke pass through the placenta to the fetus?
I am sure that it does.
Why do hairstylists wear gloves when using chemicals to dye hair?
The chemicals in the hair dye are strong enough to eat through your skin. Especially bleach.
Which route of entry are chemicals absorbed into your body through your skin or eyes?
After inhalation from the atmosphere.
What is a specialized cell that conducts impulses through the nervous system?
Neurons transmit and receive signals in the nervous system
What are the three ways in which neurons are specialized to transmit nerve impulses very quickly?
they turn in to light and go through three bones...
What is the similarities of neurons and motor neurons?
Functionally, neurons come in three varieties; motor neurons, sensory neurons and interneurons. Motor neurons conduct motor impulses from the CNS to the muscles. Sensory neurons conduct motor impulses from the rest of the body to the CNS. Interneurons connect the sensory to the motor so we can respond to incoming sensory stimuli.
How neurons transmit electro chemical impluses to the brain?
When nerve cells or neurons are stimulated they undergo chemical changes which make little waves of electricity or nerve impulses. These are based mainly on the movement of positively charged sodium and potassium ions through the neurons cell membrane.When the impulses reach a junction-synapse-they trigger the release of chemicals called neurotransmitters. These then cross the synapse and stimulate the receiving neuron to fire impules of their own. Dendrites collect nerve impulses and Axons convey impulses away from cell.
What neurons carry impulses from the brain or spinal cord to other organs and cause muscles to contract?
Impulses from the brain go mostly through the channels in the spinal cord and control most everything that goes on in the body. It is a two way street with information generated chemicals being carried throughout the body.The brain uses neurons to decide what information is acted upon.
Taste and smell impulses transmit through which of the nerves?
Sensory nerves
Nerve impulses travel to the muscles from the spinal cord through?
afferent neurons
How is contact between neurons accomplished?
Contact between neurons, as you put it, is achieved through electrical impulses towards and from your brain.
What is the neuron that carries impulses to the nervous cell body is called what?
Fibres which carry impulses towards the cell body of a neuron are called dendrites. The axon is the fibre which carries impulses away from the cell body of a neuron.
What type of neurons are responsible for transmitting nerve impulses from the spinal cord to the effector?
Signals are transmitted through the spinal cord and brain via neurons.
What is the area between neurons across which nerve impulses travel?
no, synapse. node of ranvier is between axon and dendrites
A type of tissue that sends electrical signals through the body?
Nervous tissue is composed of neurons that use electrical signals to transfer impulses throughout the body.
