Histological staining: hematoxylin & eosin
Histological staining: hematoxylin & eosin DrPhil 119 Views • 3 years ago

The most popular and one of the principal stains in histology is hematoxylin and eosin stain. It gives us an overview of the tissue and its structure. Hematoxylin binds with basophilic structures – for example DNA and RNA. So we can observe nuclei stained in blue or purple color. Eosin binds to acidophilic substances such as positively charged amino acid side chains. So as the result cytoplasm is pink or orange. All samples in laboratory are stained with H&E. There are several different types of hematoxylins and eosins used in histology which will give us different results.

In this video you will see, how we stain slides with different types of hematoxylins and eosins. Finally, we will compare the results.

How to approach histology for Human Anatomy students. Using a key will help get you through it! Add some penguin fairy dust will help too!

Please note: I mis-spoke and said "striated" instead of "stratified epithelium" a couple of times... apologies!

There are lots of histology keys out there, but the one I showed in the video is here: http://www.penguinprof.com/upl....oads/8/4/3/1/8431323

Details:

Tissue in the human body:

Epithelial: Is made of cells arranged in a continuous sheet with one or more layers, has apical & basal surfaces.

A basement membrane is the attachment between the basal surface of the cell & the underlying connective tissue.

Two types of epithelial tissues: (1) Covering & lining epithelia and (2) Glandular Epithelium.

The number of cell layers & the shape of the cells in the top layer can classify epithelium.

Simple Epithelium - one cell layer
Stratified epithelium - two or more cell layers
Pseudostratified Columnar Epithelium - When cells of an epithelial tissue are all anchored to the basement Membrane but not all cells reach the apical surface.
Glandular Epithelium -- (1) Endocrine: Release hormones directly into the blood stream and (2) Exocrine - Secrete into ducts.


Connective: contains many different cell types including: fibroblasts, macrophages, mast cells, and adipocytes. Connective Tissue Matrix is made of two materials: ground substance - proteins and polysaccharides, fiber -- reticular, collagen and elastic.

Classification of Connective Tissue:
Loose Connective - fibers & many cell types in gelatinous matrix, found in skin, & surrounding blood vessels, nerves, and organs.
Dense Connective - Bundles of parallel collagen fibers& fibroblasts, found in tendons& ligaments.
Cartilage - Cartilage is made of collagen & elastin fibers embedded in a matrix glycoprotein & cells called chondrocytes, which was found in small spaces.
Cartilage has three subtypes:
Hyaline cartilage -- Weakest, most abundant type, Found at end of long bones, & structures like the ear and nose,
Elastic cartilage- maintains shape, branching elastic fibers distinguish it from hyaline and
Fibrous Cartilage - Strongest type, has dense collagen & little matrix, found in pelvis, skull & vertebral discs.


Muscle: is divided into 3 categories, skeletal, cardiac and smooth.
Skeletal Muscle -- voluntary, striated, striations perpendicular to the muscle fibers and it is mainly found attached to bones.
Cardiac Muscle -- involuntary, striated, branched and has intercalated discs
Smooth Muscle -- involuntary, nonstriated, spindle shaped and is found in blood vessels & the GI tract.


Nervous: Consists of only two cell types in the central nervous system (CNS) & peripheral nervous system (PNS):
Neurons - Cells that convert stimuli into electrical impulses to the brain, and Neuroglia -- supportive cells.
Neurons -- are made up of cell body, axon and dendrites. There are 3 types of neurons:
Motor Neuron -- carry impulses from CNS to muscles and glands,
Interneuron - interpret input from sensory neurons and end responses to motor neurons
Sensory Neuron -- receive information from environment and transmit to CNS.
Neuroglia -- is made up of astrocytes, oligodendrocytes, ependymal cells and microglia in the CNS, and schwann cells and satellite cells in the PNS.

After the cell membranes are dissolved, the typical branching and budding yeast cells can be seen. Sometimes, it has the appearance of a tangled web of threads. At other times, only small branches will be seen.Yeast are normal inhabitants of the vagina, but only in very small numbers. If you visualize any yeast in your sample, it is considered significant.

One thing we do know: We can live without it, without apparent consequences. Appendicitis is a medical emergency that requires prompt surgery to remove the appendix. Left untreated, an inflamed appendix will eventually burst, or perforate, spilling infectious materials into the abdominal cavity.

How Blood Clots Form
How Blood Clots Form samer kareem 1,889 Views • 3 years ago

A pulmonary embolism (PE) usually happens when a blood clot called a deep vein thrombosis (DVT), often in your leg, travels to your lungs and blocks a blood vessel. That leads to low oxygen levels in your blood. It can damage the lung and other organs and cause heart failure, too. A PE can be life-threatening, so if you've been diagnosed with DVT, you should be aware of this risk. Follow the treatment plan for your DVT to stop the clot from getting bigger and to keep new clots from forming. Symptoms and Diagnosis PE won't always cause symptoms. You might have: Chest pain, which may get worse with a deep breath Sudden shortness of breath or rapid breathing Fast heartbeat Sudden cough Coughing up blood Lightheadedness or fainting Anxiety Call 911 if you notice these symptoms. They could also be symptoms of a heart attack, pneumonia, or other serious problems.
