Spinal cord histology

The tutorial explores the histology of the spinal cord, focusing on its structure and components. It begins with an overview of the histological slide, followed by a detailed examination of the meninges, gray and white matter, and their cellular composition. The video also discusses the clinical significance of spinal cord histology, particularly astrocytoma. The tutorial concludes with a summary of the key points covered.

What is the primary stain used in the histological slide of the spinal cord?

• Masson's Trichrome

• Giemsa

• Hematoxylin and Eosin

• Azan Trichome

Which layer of the meninges is known as the 'tough mother'?

• Subarachnoid Space

• Dura Mater

• Arachnoid Mater

• Pia Mater

What is the function of the arachnoid mater's trabeculae?

• To produce cerebrospinal fluid

• To form a cobweb-like structure

• To provide a tough protective layer

• To connect neurons

Which type of neuron is primarily found in the anterior horns of the spinal cord?

• Sensory Neurons

• Interneurons

• Preganglionic Neurons

• Motor Neurons

What is the role of astrocytes in the central nervous system?

• To produce myelin sheaths

• To provide physical and metabolic support

• To act as phagocytes

• To line cerebrospinal fluid spaces

Which glial cell type is responsible for myelination in the central nervous system?

• Astrocytes

• Oligodendrocytes

• Ependymal Cells

• Microglia

What is the primary characteristic of white matter in the spinal cord?

• Lack of blood vessels

• Myelinated axons

• High density of glial cells

• Presence of neuron cell bodies

What is the anterior white commissure's function in the spinal cord?

• To connect the two halves of white matter

• To produce cerebrospinal fluid

• To separate the gray matter

• To house motor neurons

What is astrocytoma?

• A protective layer of the spinal cord

• A cancer of glial cells

• A type of myelin sheath

• A type of neuron

Which diagnostic method is commonly used to confirm astrocytoma?

• Ultrasound

• Blood Test

• MRI Scan

• X-ray
