With the help of labelled diagram explain the general scheme to illustrate how nervous impulses travel
in the body
Answers
nervous tissue help in the control and coordination of the body they are made up of long neurone nervous cell called in neurone each neurone have a k Central part called the cell body or cyton many thread like branches from the extending from all part of the cell body called and run then don't bother divided to form dendrite one of these extension is longer than the rest and is called the axon
the information or message is transmitted by the a neurone in the form of impulses and in a direction only message to the neurones are conveyed by the dendrite while the messages from the neurone are conveyed through the axon
many neurones are nerve fibre bound together constitute nerve# nurse are connected to the brain and the spinal cord
Answer:
All the information from the environment is detected by the receptors (sense organ) present in the body.
The stimulus received by the receptor is passed on in the form of electrical signals to dendrites of a neuron and then to cyton of the neuron. The impulse then travels along the axon of the neuron.
On reaching the axonal end, it causes the nerve endings to release a chemical which diffuses across a synapse and stimulates the dendrites of adjacent neuron, then to their cell body to be carried along the axon. In this way, the electrical signal reaches the brain or spinal cord. The response from brain (or spinal cord) is similarly passed on to the effector, that undergoes the desired response.
