Neurons & Neuroglia

Front

What is the Central Nervous System composed of?

Back

The Central Nervous System (CNS) is composed of the brain and the spinal cord.

Front

What is the insulating membrane that surrounds parts of the axon called?

Back

The insulating membrane that surrounds parts of the axon is called the Myelin Sheath.

Front

What are the gaps between Schwann cells that increase the speed of signal transmission called?

Back

The gaps between Schwann cells are called nodes of Ranvier.

Front

Which types of cells are found in the Central Nervous System (CNS)?

Back

Astrocytes and Microglia are both found in the Central Nervous System.

Front

What is the function of dendrites in a neuron?

Back

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

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 function of myelin in the nervous system?

Back

Myelin insulates axons and increases the speed of electrical impulses along the neuron.

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 difference between sensory neurons and motor neurons?

Back

Sensory neurons carry signals from sensory receptors to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles or glands.

Front

What is the synapse?

Back

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