What is the function of terminal branches in a neuron?

Back

Terminal branches transmit nerve impulses to other neurons or target cells.

Front

What is a synapse?

Back

A synapse is the tiny gap between neurons where communication occurs, allowing nerve impulses to be sent from one neuron to another.

Front

What type of neuron carries messages from the body to the brain/spinal cord?

Back

Afferent/sensory neurons carry messages from the body to the brain/spinal cord.

Front

What is the myelin sheath?

Back

The myelin sheath is a spiral insulating material that forms a layer around the axon of a neuron, enabling faster electrical signal transmission.

Front

What type of neuron is unipolar?

Back

Unipolar neurons have a single process extending from the cell body, typically found in sensory neurons.

Front

What is the role of Schwann cells?

Back

Schwann cells produce the myelin sheath around axons in the peripheral nervous system.

Front

What are dendrites?

Back

Dendrites are the branched extensions of a neuron that receive signals from other neurons.

Front

What is the difference between afferent and efferent neurons?

Back

Afferent neurons carry sensory information to the central nervous system, while efferent neurons carry motor commands away from the central nervous system.

Front

What is the significance of neurotransmitters?

Back

Neurotransmitters are chemical messengers that transmit signals across the synapse from one neuron to another.

Front

What is the function of the axon?

Back

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