Help with Histology

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.

Bigger Muscles?? Victims of Synthol and non-muscle developing methods
Bigger Muscles?? Victims of Synthol and non-muscle developing methods Doctor 16,529 Views • 3 years ago

Some bodybuilders, particularly at professional level, use substances such as "site enhancement oil", commonly known as synthol, to mimic the appearance of developed muscle where it may otherwise be disproportionate or lagging. This is known as "fluffing". Synthol is 85% oil, 7.5% lidocain, and 7.5% alcohol.Use is legal and many brands are available on the internet.The use of injected oil to enhance muscle appearance had previously been used in the late 19th century before being abandoned due to health risks such as sclerosing lipogranuloma. Its use was revived more recently by bodybuilders. Use can cause pulmonary embolisms, nerve damage, infections, stroke, and the formation of oil-filled oleomas, cysts or ulcers in the muscle. Sesame oil is often used, which can cause allergic reactions such as vasculitis. An aesthetic issue is drooping of muscle under gravity. Surgical methods are also often employed to remove steroid-related gynecomastia in male bodybuilders, and breast implants in female bodybuilders who wish to retain a feminine physique, which can be compromised in terms of breast reduction by intense dieting.

Laparoscopic liver abscess evacuation
Laparoscopic liver abscess evacuation samer kareem 2,816 Views • 3 years ago

Pyogenic liver abscesses are mainly treated by percutaneous aspiration or drainage under antibiotic cover. If interventional radiology fails, surgical drainage becomes necessary. Recently, we performed laparoscopic liver abscess drainage successfully, and we aimed to focus on the topic in light of a systematic review of the literature.

Nerve Root Block Injection Procedure
Nerve Root Block Injection Procedure samer kareem 6,447 Views • 3 years ago

A nerve root block is an injection of local anesthetic (numbing medicine) and steroid injected under X-ray guidance into the area where the nerve exits the spinal column. A nerve root block is usually ordered by your doctor for pain in the arm or leg that follows the path of a single nerve. A nerve root block may be diagnostic (a test to determine the source of your pain) and/or therapeutic (to relieve your pain). If you get a period of sustained pain relief from the injection, the block may be repeated. Sometimes the block is done to help identify whether or not surgery might be helpful and at what level such surgery might be most helpful.

Phlebitis :  Causes and Treatment
Phlebitis : Causes and Treatment samer kareem 1,776 Views • 3 years ago

Phlebitis may occur with or without a blood clot. It can affect surface or deep veins. When caused by a blood clot, it's called thrombophlebitis. Trauma to the vein, for instance from an IV catheter, is a possible cause. Symptoms include redness, warmth, and pain in the affected area. Treatments may include a warm compress, anti-inflammatory medication, compression stockings, and blood thinners.

Craniectomy
Craniectomy samer kareem 63,593 Views • 3 years ago

A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called the bone flap. The bone flap is temporarily removed, then replaced after the brain surgery has been done.

Septoplasty (SEP-toe-plas-tee) is a surgical procedure to correct a deviated septum — a displacement of the bone and cartilage that divides your two nostrils. During septoplasty, your nasal septum is straightened and repositioned in the middle of your nose.
