Peripheral Nervous System Flashcardzizz

Front

What are dendrites?

Back

Dendrites are the parts of a neuron that receive electrical impulses from neighboring neurons.

Front

What is the cell body of a neuron?

Back

The cell body, or soma, is the part of a neuron that contains the nucleus and organelles, and is responsible for maintaining the cell's health.

Front

What does the sympathetic nervous system do?

Back

The sympathetic nervous system shunts blood to skeletal muscles and the heart, preparing the body for 'fight or flight' responses.

Front

Where do ganglia form in the sympathetic nervous system?

Back

Ganglia form a trunk close to the spinal cord in the sympathetic nervous system.

Front

What is the sympathetic chain?

Back

The sympathetic chain is a series of ganglia located close to the spinal cord that are part of the sympathetic nervous system.

Front

What is the role of the parasympathetic nervous system?

Back

The parasympathetic nervous system conserves energy and promotes 'rest and digest' functions.

Front

What is the function of axons?

Back

Axons are long projections of neurons that transmit electrical impulses away from the cell body to other neurons or muscles.

Front

What is myelin sheath?

Back

Myelin sheath is a fatty layer that insulates axons, speeding up the transmission of electrical impulses.

Front

What are synapses?

Back

Synapses are the junctions between neurons where neurotransmitters are released to transmit signals.

Front

What is the difference between the sympathetic and parasympathetic nervous systems?

Back

The sympathetic nervous system prepares the body for action, while the parasympathetic nervous system promotes relaxation and recovery.
