Neuron Structure and function

Front

What are the gaps between Schwann cells (myelin) that allow the signal to jump/skip down the neuron called?

Back

Nodes of Ranvier.

Front

What is the insulating material that forms a layer around the axon of a neuron?

Back

Myelin sheath.

Front

What is the part of the neuron that carries signals away from the cell body?

Back

Axon.

Front

What area of the neuron processes the signal from the dendrites and carries it to the axon?

Back

Cell body.

Front

What is the function of dendrites in a neuron?

Back

Dendrites receive signals from other neurons.

Front

What is the role of the myelin sheath in neuron function?

Back

The myelin sheath insulates the axon and speeds up signal transmission.

Front

What is a synapse?

Back

A synapse is the junction between two neurons where signals are transmitted.

Front

What are neurotransmitters?

Back

Neurotransmitters are chemical messengers that transmit signals across a synapse.

Front

What is the function of the nucleus in a neuron?

Back

The nucleus contains the cell's genetic material and controls its activities.

Front

What is the difference between an electrical signal and a chemical signal in neurons?

Back

An electrical signal is a rapid change in voltage along the axon, while a chemical signal involves neurotransmitters crossing the synapse.
