how to Nerve cells carry nerve impulses or electrical impulses from one part of the body to other
Answers
Answer:
Explanation:
Teamwork
Your neurons can be divided into three types:
Sensory neurons, which pass information about stimuli such as light, heat or chemicals from both inside and outside your body to your central nervous system .
Motor neurons, which pass instructions from your central nervous system to other parts of your body, such as muscles or glands .
Association neurons, which connect your sensory and motor neurons .
Your neurons carry messages in the form of electrical signals called nerve impulses. To create a nerve impulse, your neurons have to be excited. Stimuli such as light, sound or pressure all excite your neurons, but in most cases, chemicals released by other neurons will trigger a nerve impulse.
Although you have millions of neurons that are densely packed within your nervous system, they never actually touch. So when a nerve impulse reaches the end of one neuron, a neurotransmitter chemical is released. It diffuses from this neuron across a junction and excites the next neuron.
Answer:
Explanation:There are receptors present in our sense organs.
The dendretic tip of a nerve cell sets off a chemical reaction that create electric impulse. This impulse travels along axon . these impulse cross synape and start a similar electric impulse INA a dendrite of next neuron. This is how nervous impulse travel in body from one to another part
