What is the cerebrum?

Back

The cerebrum is the largest part of the brain, responsible for higher brain functions, including thought, action, and sensory processing. It contains the left and right hemispheres.

Front

What is the function of the Arachnoid Mater?

Back

The Arachnoid Mater is one of the three meninges that surround the brain and spinal cord. It contains a space (subarachnoid space) filled with cerebrospinal fluid, which cushions the brain.

Front

Which part of the brain is NOT part of the brainstem?

Back

The Epithalamus is not part of the brainstem; the brainstem consists of the midbrain, pons, and medulla oblongata.

Front

What is the role of the Hypothalamus?

Back

The Hypothalamus regulates homeostasis by controlling body temperature, hunger, thirst, and circadian rhythms.

Front

What is the blood-brain barrier?

Back

The blood-brain barrier is a selective permeability barrier that protects the brain from harmful substances while allowing essential nutrients to pass through.

Front

What is the structure of the blood-brain barrier?

Back

The blood-brain barrier consists of a capillary wall with a thick basal lamina and tight junctions between endothelial cells, along with perivascular feet of astrocytes acting as gatekeepers.

Front

What are the three layers of meninges?

Back

The three layers of meninges are the Dura Mater (outer layer), Arachnoid Mater (middle layer), and Pia Mater (inner layer).

Front

What is the function of the Medulla Oblongata?

Back

The Medulla Oblongata controls autonomic functions such as breathing, heart rate, and blood pressure.

Front

What is the role of the Thalamus?

Back

The Thalamus acts as a relay station for sensory and motor signals to the cerebral cortex and is involved in the regulation of consciousness and sleep.

Front

What are astrocytes?

Back

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