PNS Flashcard Game

Front

What is the function of the axon terminal in a neuron?

Back

The axon terminal is responsible for releasing neurotransmitters into the synaptic cleft, allowing communication between neurons.

Front

What part of a neuron receives signals from other neurons?

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 the significance of the node of Ranvier?

Back

The node of Ranvier is a gap in the myelin sheath that facilitates rapid conduction of nerve impulses through saltatory conduction.

Front

What is the primary function of Schwann cells?

Back

Schwann cells produce the myelin sheath that insulates axons in the peripheral nervous system, enhancing signal transmission.

Front

What does PNS stand for in the context of the nervous system?

Back

PNS stands for Peripheral Nervous System, which includes all the nerves outside the brain and spinal cord.

Front

What is the difference between the CNS and PNS?

Back

The CNS (Central Nervous System) consists of the brain and spinal cord, while the PNS includes all other neural elements.

Front

What are neurotransmitters?

Back

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

Front

What is the function of the autonomic nervous system?

Back

The autonomic nervous system regulates involuntary bodily functions, such as heart rate and digestion.

Front

What is the role of the somatic nervous system?

Back

The somatic nervous system controls voluntary movements and transmits sensory information to the CNS.
