Neurons

Question 1

Neurons are

Answer 1

cells that transmit nerve impulses from one part of the body to another.”

Question 2

Neurons

Answer 2

cells that transmit nerve impulses from one part of the body to another.”

Question 3

Although neourons differ structural from one another they have common features

Answer 3

The nucleus and the procceses extending from the cell body

Question 4

All neurons have three characteristic structural features

Answer 4

Cell body, a receptive portion and transmitting portion

Question 5

Dendrites

Answer 5

Multiple branching processes called dendrites extend from the soma

Question 6

Axon

Answer 6

A thin single axon also extends the soma

Question 7

Neurons function

Answer 7

Dendrites receive impulses (signals) from another neuron or cell.
The cell body (soma) processes and integrates this information.
The processed signal is then sent to the axon.
The axon carries the outgoing signal to the next neuron or target cell.

Question 8

Synapses

Answer 8

Signals from other neurons arrive at the synapse, where the axon terminals of one neuron meet the dendrites of another

Question 9

Each neuron has a single axon

Answer 9

“Every neuron has one axon, which arises from the cell body at a region called the axon hillock. Axons can branch, forming collaterals, and at their ends, they can further divide into thousands of axon terminals.”
