Do Ear Candles Remove Earwax?
Do Ear Candles Remove Earwax? samer kareem 2,674 Views • 2 years ago

We are aware that the "official" way to use an ear candle is small end down into the ear, but for this video, we have elected to use it the way most "lay" public would (small end up). Ear candling is an alternative medicine practice that is thought to remove earwax. However, this video illustrates how ineffective this practice is in removing earwax... and can potentially be even harmful. And yes... It is still frequently practiced.

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.

COPD - Chronic Obstructive Pulmonary Disease
COPD - Chronic Obstructive Pulmonary Disease samer kareem 17,163 Views • 2 years ago

Chronic obstructive pulmonary disease Email this page to a friend Print Facebook Twitter Google+ Chronic obstructive pulmonary disease (COPD) is a common lung disease. Having COPD makes it hard to breathe. There are two main forms of COPD: Chronic bronchitis, which involves a long-term cough with mucus Emphysema, which involves damage to the lungs over time Most people with COPD have a combination of both conditions. Causes Smoking is the main cause of COPD. The more a person smokes, the more likely that person will develop COPD. But some people smoke for years and never get COPD. In rare cases, nonsmokers who lack a protein called alpha-1 antitrypsin can develop emphysema. Emphysema Other risk factors for COPD are: Exposure to certain gases or fumes in the workplace Exposure to heavy amounts of secondhand smoke and pollution Frequent use of a cooking fire without proper ventilation Symptoms Symptoms may include any of the following: Cough, with or without mucous Fatigue Many respiratory infections Shortness of breath (dyspnea) that gets worse with mild activity Trouble catching one's breath Wheezing Because the symptoms develop slowly, some people may not know that they have COPD.

Rectocele
Rectocele samer kareem 16,871 Views • 2 years ago

-Rectocele is a relatively common condition in older women and is characterized by the displacement of the rectum through posterior vaginal wall defect(s). The condition is typically caused by damage to the rectovaginal septum incurred during vaginal childbirth and is exacerbated by periodic increases in intraabdominal pressure (e.g., when laughing or coughing) and the effects of gravity. Women with symptomatic rectoceles who are poor surgical candidates may be treated with pessaries, which are structures designed to support the vaginal wall. Pessaries should only be used in conjunction with vaginal

NEURON ACTION POTENTIAL
NEURON ACTION POTENTIAL samer kareem 4,044 Views • 2 years ago

Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.

Modified Radical Mastectomy
Modified Radical Mastectomy samer kareem 4,353 Views • 2 years ago

A modified radical mastectomy is a procedure in which the entire breast is removed, including the skin, areola, nipple, and most axillary lymph nodes; the pectoralis major muscle is spared. Historically, a modified radical mastectomy was the primary method of treatment of breast cancer. [1, 2] As the treatment of breast cancer evolved, breast conservation has become more widely used. [3, 4] However, mastectomy still remains a viable option for women with breast cancer. [5, 6]

Removing a 20-CM Long Loa Loa Worm from the Eye
Removing a 20-CM Long Loa Loa Worm from the Eye Scott 4,387 Views • 2 years ago

Loa loa filariasis (also known as loiasis, loaiasis, Calabar swellings, Fugitive swelling, Tropical swelling and African eyeworm) is a skin and eye disease caused by the nematode worm, loa loa. Humans contract this disease through the bite of a Deer fly or Mango fly (Chrysops spp), the vectors for Loa loa. The adult Loa loa filarial worm migrates throughout the subcutaneous tissues of humans, occasionally crossing into subconjunctival tissues of the eye where it can be easily observed. Loa loa does not normally affect one's vision but can be painful when moving about the eyeball or across the bridge of the nose.The disease can cause red itchy swellings below the skin called "Calabar swellings". The disease is treated with the drug diethylcarbamazine (DEC), and when appropriate, surgical methods may be employed to remove adult worms from the conjunctiva.
