Basic histological staining methods (preview) - Human Histology | Kenhub DrPhil 179 Views • 3 years ago

In order to be able to look at tissues under a microscope, we need to first stain them with the right technique. Learn the main staining techniques used in histology today on our full video: https://khub.me/aux9w

As you probably know, histology is the study of the microscopic anatomy of cells and tissues. So we use staining methods to visualize and distinguish the different parts of cells and tissues since cells and their structures are usually transparent or colorless. The types of dyes used to color cells and their components can either be specific to particular structures, chemical groups or even molecules, and it can also be non-specific in which case most of the cell is stained in the same way.

When staining tissue samples, dyes that are used are either acidic or basic or a combination of the two. And why is that, you might be asking. Well, cellular structures such as nucleic acids or proteins have charged groups which are known as phosphate groups or carboxyl groups, just to name a couple. The dyes used in histology are colored organic compounds which also have a charge. Acidic dyes carry a negative charge and so they bind to positively-charged cell structures.

In the full version of this tutorial, we will cover some of the most common types of dyes used in histological staining of cells and their structures:
- basic dyes vs acidic dyes vs neutral dyes;
- hematoxylin and eosin;
- PAS - staining;
- Golgi method;
- Toluidine blue;
- Masson's trichrome;
- Osmium tetroxide;

Craniotomy and Craniectomy Scott 341 Views • 3 years ago

http://www.nucleushealth.com/ - This 3D medical animation depicts two operations, called craniotomy and craniectomy, in which the skull is opened to access the brain. The normal anatomy of the skull and tissues surrounding the brain are shown, including arteries and veins. The animation lists the common reasons for these procedures, and briefly introduces intracranial pressure.

Video ID: ANH13109

Transcript:

Your doctor may recommend a craniotomy or a craniectomy procedure to treat a number of different brain diseases, injuries, or conditions.

Your skull is made of bone and serves as a hard, protective covering for your brain. Just inside your skull, three layers of tissue, called meninges, surround your brain. The thick, outermost layer is the dura mater. The middle tissue layer is the arachnoid mater and the innermost layer is the pia mater. Between the arachnoid mater and the pia mater is the subarachnoid space, which contains blood vessels and a clear fluid called cerebrospinal fluid. Blood vessels, called bridging veins, connect the surface of your brain with the dura mater. Other blood vessels, called cerebral arteries, bring blood to your brain.

Inside your skull, normal brain function requires a delicate balance of pressure between the blood in your blood vessels, the cerebrospinal fluid that surrounds your brain, and your brain tissue. This is called normal intracranial pressure. Increased intracranial pressure may result from: brain tumors, head injuries, problems with your blood vessels, or infections in your brain or spinal cord. These conditions put pressure on your brain and may cause it to swell or change shape inside your skull, which can lead to serious brain injury.

Your doctor may recommend a craniotomy to remove: abnormal brain tissue, such as a brain tumor, a sample of tissue by biopsy, a blood clot, called a hematoma, excess cerebrospinal fluid, or pus from an infection, called an abscess.

A craniotomy may also be done to: relieve brain swelling,
stop bleeding, called a hemorrhage, repair abnormal blood vessels, repair skull fractures, or repair damaged meninges.

Finally, a craniotomy may also be done to: treat brain conditions, such as epilepsy, deliver medication to your brain, or implant a medical device, such as a deep brain stimulator.

The most common reason for a craniotomy is to remove a brain tumor.
