This sqadia.com short video clip is a brief explanation of Epithelium.

Epithelium is one of the four basic tissues of the body and is derived from all three germ layers.

It is composed of very closely packed, contiguous cells, with very little or no extracellular material in the extracellular spaces.

When there are two or more layers of cells epithelia is referred to as stratified, hence can be stratified squamous, stratified cuboidal and stratified columnar.

How To Increase Memory Power, How To Improve Memory Retention, How To Boost Memory Power.--- http://brain-revitalizer.info-pro.co ---- Brain Exercises, When people think of exercising it often involves physical exertion to strengthen muscles. The human brain is also an important "muscle" in the body and with the right brain training and brain exercises you can help keep your mind fit, alert and ready to handle the rigors of a typical working day. Often brain exercises come in the form of games that help train the brain improve memory, strategize and think in advance. Some common forms of brain exercise include chess, memory games and mathematical problem solving. Another way to exercise the brain is through brainwave entrainment. Isochronic tones are computer generated tones that are pulsed at specific frequencies to achieve desired effects such as productivity or relaxation. Although brainwave entrainment is not a new practice -- binaural beats have been used in brain training since the mid-1800's -- the use of computer generated isochronic tones has become more popular lately and are also proving to be more effective in helping people improve their memory and intelligence. Unfortunately when most people stop formal schooling, either by achieving a degree or choosing to drop out, the study habits and brain training that was part of their daily schedule also ends. The memorization and critical thinking that helped get us through school shouldn't have to stop just because a specific goal has been reached. In fact, if you don't keep up with brain exercises your mind will become lazy and won't function in the as sharply as it used to. The fact is, most people will never learn what it REALLY feels like to have their brains operating at a high capacity. They'll haphazardly try a few things, wonder why nothing is working, then go back to their mundane existence. But YOU can be different! You can use Genius Brain Power to empower your brain so that you come alive with more energy, learn quicker, think more creatively, focus on your work like never before and drastically reduce stress with amazingly deep states of relaxation and meditation. click here: http://brain-revitalizer.info-pro.co

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.

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.

Bell's palsy is a form of temporary facial paralysis resulting from damage or trauma to the facial nerves. The facial nerve-also called the 7th cranial nerve-travels through a narrow, bony canal (called the Fallopian canal) in the skull, beneath the ear, to the muscles on each side of the face. For most of its journey, the nerve is encased in this bony shell. Each facial nerve directs the muscles on one side of the face, including those that control eye blinking and closing, and facial expressions such as smiling and frowning. Additionally, the facial nerve carries nerve impulses to the lacrimal or tear glands, the saliva glands, and the muscles of a small bone in the middle of the ear called the stapes. The facial nerve also transmits taste sensations from the tongue. When Bell's palsy occurs, the function of the facial nerve is disrupted, causing an interruption in the messages the brain sends to the facial muscles. This interruption results in facial weakness or paralysis. Bell's palsy is named for Sir Charles Bell, a 19th century Scottish surgeon who described the facial nerve and its connection to the condition. The disorder, which is not related to stroke, is the most common cause of facial paralysis. Generally, Bell's palsy affects only one of the paired facial nerves and one side of the face, however, in rare cases, it can affect both sides.

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

Thoracentesis is a procedure used to obtain a sample of fluid from the space around the lungs. Normally, only a thin layer of fluid is present in the area between the lungs and chest wall. However, some conditions can cause a large amount of fluid to accumulate. This collection of fluid is called a pleural effusion.

If you're pregnant or might become pregnant, it's critically important to get enough folic acid, the synthetic form of vitamin B9, also known as folate. Folic acid helps prevent neural tube defects (NTDs) – serious birth defects of the spinal cord (such as spina bifida) and the brain (such as anencephaly).

According to a recent study, most people's sexual romps last about 1.5–7 minutes. But, as Dr. Harry Fisch writes in his new book The New Naked: The Ultimate Sex Education for Grownups, 45 percent of men come in two minutes or less, leaving their female partners orgasmless. Here are some ways to extend your man's sexual stamina, and more likely have an orgasm yourself in the process.

Trigger finger, also known as stenosing tenosynovitis (stuh-NO-sing ten-o-sin-o-VIE-tis), is a condition in which one of your fingers gets stuck in a bent position. Your finger may straighten with a snap — like a trigger being pulled and released. Trigger finger occurs when inflammation narrows the space within the sheath that surrounds the tendon in the affected finger. If trigger finger is severe, your finger may become locked in a bent position. People whose work or hobbies require repetitive gripping actions are at higher risk of developing trigger finger. The condition is also more common in women and in anyone with diabetes. Treatment of trigger finger varies depending on the severity.
