Front

What are sensory neurons?

Back

Nerve cells responsible for receiving external stimuli from the environment and transmitting signals to the CNS.

Front

What is the role of the Peripheral Nervous System (PNS)?

Back

The PNS connects the CNS to the limbs and organs, facilitating communication between the brain and the rest of the body.

Front

What is the function of dendrites in a neuron?

Back

Dendrites receive signals from other neurons and transmit them to the cell body.

Front

What is the role of the axon in a neuron?

Back

The axon transmits electrical impulses away from the cell body to other neurons or muscles.

Front

What is a synapse?

Back

A synapse is the junction between two neurons where signals are transmitted.
