HBS 2.2.1 The Neuron

Front

What is the function of a dendrite?

Back

Dendrites are the parts of a neuron that receive chemical messages from neurotransmitters of other neurons.

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 does the myelin sheath do?

Back

The myelin sheath insulates the axon and increases the speed of the neural message within the neuron.

Front

What is an axon terminal?

Back

The axon terminal is the part of the neuron that releases neurotransmitters into the synaptic cleft.

Front

What is a synapse?

Back

A synapse is the junction between two neurons where neurotransmitters are released.

Front

What is the cell body of a neuron?

Back

The cell body contains the nucleus and organelles, and it integrates signals received from the dendrites.

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 axon terminal button?

Back

The axon terminal button releases neurotransmitters into the synaptic cleft.

Front

How do dendrites contribute to neural communication?

Back

Dendrites receive signals from other neurons, allowing for communication and processing of information.

Front

What is the significance of the myelin sheath in neural conduction?

Back

The myelin sheath allows for faster transmission of electrical impulses along the axon.
