Neuron Synapse

Front

What is a neuron?

Back

A neuron is a specialized cell that transmits nerve impulses in the nervous system.

Front

What is the function of dendrites?

Back

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

Front

What is a synapse?

Back

A synapse is the junction between two neurons where communication occurs.

Front

What are neurotransmitters?

Back

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

Front

What is the role of the axon?

Back

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

Front

What happens during reuptake?

Back

Reuptake is the process by which excess neurotransmitters in the synapse are reabsorbed by the presynaptic neuron.

Front

What is the function of the motor neuron?

Back

Motor neurons transmit signals from the central nervous system to muscles, causing movement.

Front

What is the role of acetylcholine in synaptic transmission?

Back

Acetylcholine binds to receptors on the postsynaptic cell, opening Na+ gated channels and initiating a response.

Front

What is the difference between sensory neurons and motor neurons?

Back

Sensory neurons carry signals from sensory receptors to the central nervous system, while motor neurons carry signals from the central nervous system to muscles.

Front

What is resting potential?

Back

Resting potential is the electrical charge difference across the neuron's membrane when it is not actively transmitting a signal.
