Mitochondria, ribosomes, and cytoplasm.
Cell wall , vacuole , and cytoplasm
What is the function of dendrites?
To transmit impulses from the neuron to other cells.
To divide the cell.
To receive signals from other neurons.
To produce neurotransmitters.
What is the long extension of a neuron called?

What is the main function of a neuron?
To divide and regenerate
To store nutrients.
To generate and transmit nerve impulses.
To provide support to other cells.
What is the role of sensory neurons?
To carry signals to the muscles.
To connect sensory and motor neurons.
To carry signals from sensory organs to the nervous system.
To protect interneurons.
Where are interneurons located?
In muscles.
In the brain and spinal cord.
In sensory organs.
In the skin.
What do motor neurons do?
Receive signals from sensory organs.
Send signals to muscles or effector cells.
Connect to glial cells.
Store nerve impulses.
Why are myelinated axons faster than unmyelinated axons?
Myelin allows faster signal conduction.
They are longer.
