Cervical screening test
Cervical screening test samer kareem 22,238 Views • 3 years ago

Women are routinely invited to have cervical screening tests (also called smear tests). The tests are done to prevent cervical cancer, not to diagnose cancer. During each test some cells are removed from the neck of the womb (cervix), with a plastic brush. The cells are examined under a microscope to look for early changes that, if ignored and not treated, could develop into cancer of the cervix. You are very unlikely to develop cervical cancer if you have regular cervical screening tests at the times advised by your doctor. If the test shows any abnormality, you will have treatment to stop you ever getting cancer of the cervix. So, an abnormal test does not mean you have cancer. It means you should have some treatment to stop you getting cancer.

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.

Cleft Palate Surgery: Preparing for your procedure at C.S. Mott Children's Hospital
Cleft Palate Surgery: Preparing for your procedure at C.S. Mott Children's Hospital Surgeon 275 Views • 3 years ago

Cleft palate is among the most common birth defects affecting children in North America. The incomplete formation of the roof of the mouth can occur individually, or in addition to cleft lip. Cleft palate repair is a type of plastic surgery to correct this abnormal development both to restore function and a more normal appearance. This video explains what to expect for families scheduled for cleft palate surgery at the Craniofacial Anomalies Program at University of Michigan C.S. Mott Children's Hospital.

Myelomeningocele Closure
Myelomeningocele Closure samer kareem 2,835 Views • 3 years ago

Myelomeningocele remains the most complex congenital malformation of the central nervous system that is compatible with life. This lesion results when the neural tube fails to fold normally during postovulatory Days 21 to 27.[6] The exact cause of disorders remains under some historical debate and is not within the scope of this paper. Myelomeningocele within the context of this discussion refers only to lesions that involve an open caudal neural tube defect on the surface of the skin

McCannel Suture fixation of IOL to iris using standard and Sipser-chang technique
McCannel Suture fixation of IOL to iris using standard and Sipser-chang technique Scott 19,309 Views • 3 years ago

Here Drs Oetting and Shriver of the University of Iowa demonstrate the McCannel technique of fixing an IOL to the iris. In this video both the standard McCannel suture retrieval technique and the Siepser/Chang modifed technique are demonstrated. A 10-O prolene with a long curved ctc-6 needle is u...sed to place a suture through the iris and under an 3 piece IOL haptic. Using the standard technique the two ends of the suture are retrieved through a common paracentesis near the fixation site and tied externally. The other haptic is tied using the Siepser sliding knot technique as described by Chang for this indication with an internal knot. The standard technique is a bit easier but does not allow as thight a knot for fixation of the iris to the haptic.

Anal Fissure
Anal Fissure samer kareem 4,966 Views • 3 years ago

An anal fissure is a small tear in the thin, moist tissue (mucosa) that lines the anus. An anal fissure may occur when you pass hard or large stools during a bowel movement. Anal fissures typically cause pain and bleeding with bowel movements. You also may experience spasms in the ring of muscle at the end of your anus (anal sphincter). Anal fissures are very common in young infants but can affect people of any age. Most anal fissures get better with simple treatments, such as increased fiber intake or sitz baths. Some people with anal fissures may need medication or, occasionally, surgery.

Ganglion Cyst
Ganglion Cyst samer kareem 2,400 Views • 3 years ago

Ganglion cysts are noncancerous lumps that most commonly develop along the tendons or joints of your wrists or hands. They also may occur in the ankles and feet. Ganglion cysts are typically round or oval and are filled with a jellylike fluid. Small ganglion cysts can be pea-sized, while larger ones can be around an inch (2.5 centimeters) in diameter. Ganglion cysts can be painful if they press on a nearby nerve. Their location can sometimes interfere with joint movement. If your ganglion cyst is causing you problems, your doctor may suggest trying to drain the cyst with a needle. Removing the cyst surgically also is an option. But if you have no symptoms, no treatment is necessary. In many cases, the cysts go away on their own.

This video: Blisters caused by friction or minor burns do not require a doctor's care. New skin will form underneath the affected area and the fluid is simply absorbed. Do not puncture a blister unless it is large, painful, or likely to be further irritated. The fluid-filled blister keeps the underlying skin clean, which prevents infection and promotes healing.
