Cerebral cortex histology

This tutorial explores the cerebral cortex, focusing on its histology and anatomy. It covers the brain's gross anatomy, neuron structure, and the differences between gray and white matter. The video also examines the roles of neurons and glial cells, and discusses clinical notes on multiple sclerosis, highlighting its effects on brain tissue. The tutorial concludes with a recap of the key points covered.

What is the primary focus of this tutorial?

• The entire brain

• The cerebellum

• The spinal cord

Which part of the brain is responsible for higher functions?

• Cerebellum

• Brain stem

• Cerebrum

• Thalamus

What is the main component of gray matter?

• Blood vessels

• Glial cells

What staining technique is used in the histology of the cerebral cortex?

• Hematoxylin and Eosin stain

• Gram stain

• Wright's stain

• Giemsa stain

What is the function of the pia mater?

• To connect the brain to the spinal cord

• To produce cerebrospinal fluid

• To protect the surface of the gray matter

• To insulate axons

What is the role of glial cells in the CNS?

• Form the blood-brain barrier

• Transmit information

• Support and protect neurons

• Conduct electrical signals

Which type of glial cell is most common in the CNS?
