Front

What are gyri?

Back

Gyri are the ridges on the surface of the brain, which increase the surface area and are involved in various brain functions.

Front

What is the role of microglia in the brain?

Back

Microglia are a type of glial cell that phagocytize (engulf and digest) microorganisms and neuronal debris, playing a crucial role in the brain's immune response.

Front

What do oligodendrocytes do?

Back

Oligodendrocytes are glial cells in the central nervous system (CNS) that wrap around nerve fibers to form myelin sheaths, which insulate the fibers and enhance signal transmission.

Front

What is the thalamus?

Back

The thalamus is a brain structure that acts as a relay station for sensory and motor signals to the cerebral cortex.

Front

What does the letter 'A' represent in a neuron diagram?

Back

In a neuron diagram, the letter 'A' typically represents the dendrite, which is the part of the neuron that receives signals from other neurons.

Front

What are sulci?

Back

Sulci are the grooves or indentations on the surface of the brain that separate the gyri.

Front

What is the function of astrocytes?

Back

Astrocytes are star-shaped glial cells that support neurons, maintain the blood-brain barrier, and regulate blood flow in the brain.

Front

What is the function of ependymal cells?

Back

Ependymal cells line the ventricles of the brain and the central canal of the spinal cord, producing and circulating cerebrospinal fluid (CSF).

Front

What is the role of Schwann cells?

Back

Schwann cells are glial cells in the peripheral nervous system (PNS) that wrap around nerve fibers to form myelin sheaths, similar to oligodendrocytes in the CNS.

Front

What is the significance of the medulla oblongata?

Back

The medulla oblongata is a part of the brainstem that controls vital autonomic functions such as breathing, heart rate, and blood pressure.
