Front

What is the myelin sheath?

Back

The myelin sheath is a protective covering that surrounds the axon of some neurons, which helps to speed up electrical impulses along the nerve cell.

Front

What is the primary function of dendrites?

Back

Dendrites are the parts of a neuron that receive signals from other neurons and transmit them to the cell body.

Front

What are neurons?

Back

Neurons are specialized cells in the nervous system responsible for transmitting signals throughout the body.

Front

What are glial cells?

Back

Glial cells are non-neuronal cells in the nervous system that support, protect, and maintain the function of neurons.

Front

What is the main function of the nervous system?

Back

The main function of the nervous system is to carry electrical signals from one area of the body to another, facilitating communication and coordination.

Front

What are the two main types of neurons?

Back

The two main types of neurons are sensory neurons, which carry signals from sensory receptors to the central nervous system, and motor neurons, which carry signals from the central nervous system to muscles.

Front

What is an axon?

Back

An axon is a long, slender projection of a neuron that conducts electrical impulses away from the cell body.

Front

What role do synapses play in the nervous system?

Back

Synapses are the junctions between neurons that allow them to communicate with each other by transmitting signals.

Front

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

Back

The cell body contains the nucleus and organelles, and it is responsible for maintaining the cell's health and processing incoming signals.

Front

What is the difference between afferent and efferent neurons?

Back

Afferent neurons carry sensory information to the central nervous system, while efferent neurons carry motor commands from the central nervous system to muscles.
