Nervous System Unit Test

Front

What is the function of the Axon Terminal?

Back

The Axon Terminal is responsible for transmitting signals to other neurons or target cells by releasing neurotransmitters.

Front

What is the largest area of the brain responsible for conscious thought and action?

Back

The Cerebrum is the largest part of the brain and is responsible for all conscious activities.

Front

What are neurotransmitters?

Back

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

Front

What role do ependymal cells play in the nervous system?

Back

Ependymal cells are neuroglial cells that produce and circulate cerebrospinal fluid.

Front

What is a synapse?

Back

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

Front

What is the primary role of dendrites in a neuron?

Back

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

Front

What is the function of the axon in a neuron?

Back

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

Front

What are oligodendrocytes?

Back

Oligodendrocytes are a type of neuroglial cell that insulates axons in the central nervous system.

Front

What is the role of microglia in the nervous system?

Back

Microglia act as the immune cells of the central nervous system, protecting it from pathogens and clearing debris.

Front

What is the threshold in the context of neuron firing?

Back

The threshold is the minimum level of stimulus required to trigger an action potential in a neuron.
