Neurons

Front

What is the basic working unit of the brain and nervous system that processes and transmits information?

Back

Neuron

Front

What part of the neuron stores and releases neurotransmitters into the synapse?

Back

Axon Terminal

Front

What is the function of the cell body in a neuron?

Back

The cell body contains the nucleus and organelles, and it integrates incoming signals.

Front

What part of the neuron receives chemical messages from neurotransmitters of other neurons?

Back

Dendrites

Front

What are neurotransmitters?

Back

Chemicals used by neurons to transmit impulses across synapses to other nerve cells.

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 myelin sheath and its function?

Back

A fatty layer that insulates the axon and speeds up the transmission of impulses.

Front

What is the synapse?

Back

The junction between two neurons where neurotransmitters are released.

Front

What is the difference between excitatory and inhibitory neurotransmitters?

Back

Excitatory neurotransmitters increase the likelihood of a neuron firing, while inhibitory neurotransmitters decrease it.

Front

What is the resting potential of a neuron?

Back

The electrical charge difference across the neuron's membrane when it is not actively transmitting an impulse.
