Questions and Answers

How do we detect that we are touching a hot object?

Information is detected by the specialised tips of nerve cells (correct)
The release of chemicals causes a sensation of heat
The electrical impulse travels from the cell body to the dendrite
The axon delivers the electrical impulse to the sense organs

What creates an electrical impulse in response to information acquired at the end of the dendritic tip of a nerve cell?

Chemical reaction (correct)
Cell body
Synapse
Axon

What is the function of the synapse in the nervous system?

Starts a chemical reaction in the dendrite of the next neuron
Transfers information via electrical impulses from one part of the body to another
Delivers electrical impulses to muscle cells
Crosses the gap and starts a similar electrical impulse in the dendrite of the next neuron (correct)

Describe the general scheme of how nervous impulses travel in the body.

The electrical impulse travels from the dendrite to the cell body, then along the axon to its end, and sets off the release of chemicals at the end of the axon, which cross the synapse to start a similar electrical impulse in the next neuron's dendrite. Signup and view all the answers

What is the nervous tissue made up of, and what is its specialized function?

Nervous tissue is made up of an organised network of nerve cells or neurons, and is specialised for conducting information via electrical impulses from one part of the body to another. Signup and view all the answers
