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.

LASIK, or "laser-assisted in situ keratomileusis," is the most commonly performed laser eye surgery to treat myopia, hyperopia and astigmatism. The goal of the treatment is to reshape the cornea to correct the refractive error of the eye.
The cornea is the transparent dome-shaped structure in front of the eye. The cornea refracts light and accounts for about two-thirds of the eye's total optical power. Altering the curvature of the cornea changes the way light rays enter the eye. As a result, the light rays can be focused properly onto the retina for clearer vision.
For nearsighted people, the laser is used to flatten the cornea. For farsighted people, the cornea is made steeper. For patients with astigmatism, the laser is used to smooth the irregularly-shaped cornea into a more regular shape.
The outer layer of the cornea - the epithelium – is capable of replacing itself within a few days after being damaged or removed. The deeper layer of the cornea – the stroma, on the contrary, is a permanent corneal tissue with very limited regenerative capacity. The stroma, if reshaped by a laser, will remain that way permanently.
In this procedure, a thin, circular "FLAP" is created in the surface of the cornea to gain access to the permanent corneal tissue. This can be done with a mechanical cutting tool called a microkeratome, OR, for a blade-free experience, by a femtosecond laser. An excimer laser is then used to remove some corneal tissue to reshape the cornea. Excimer laser uses cool ultraviolet light beams to vaporize microscopic amounts of tissue in a precise manner to accurately reshape the cornea. The excimer laser is computer-controlled and is programmed based on the patient’s refractive error. The flap is then laid back in place and is allowed to heal.
LASIK eye surgery is mostly painless and can be completed within minutes. Improved vision can usually be seen overnight.

PRK, or photorefractive keratectomy, was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. In PRK, NO flap is created. Rather, the epithelial cells on the eye surface are simply removed. An excimer laser is then used to reshape the cornea just like it does in LASIK.
The vision correction outcomes of PRK surgery are comparable to those of LASIK, but the recovery period is longer. This is because the epithelium is completely removed in PRK and it takes a few days to regenerate. PRK patients also have more discomfort and haziness of vision in the first few days after the surgery. Improved vision also takes longer to achieve.
PRK does, however, offer certain advantages. Because PRK does not involve creation of a flap, which contains both epithelial and deeper stromal tissue, the entire thickness of the stroma is available for treatment. The treatment range is therefore higher. This is particularly useful for patients with high levels of myopia or for those whose cornea is too thin for LASIK. PRK is also free of flap-related complication risks.

Sports Hernia Diagnosis

What Is A Sports Hernia?

A sports hernia is tearing of the transversalis fascia of the lower abdominal or groin region. A common misconception is that a sports hernia is the same as a traditional hernia. The mechanism of injury is rapid twisting and change of direction within sports, such as football, basketball, soccer and hockey.

The term “sports hernia” is becoming mainstream with more professional athletes being diagnosed. The following are just to name a few:

Torii Hunter
Tom Brady
Ryan Getzlaf
Julio Jones
Jeremy Shockey
If you follow any of these professional athletes, they all seem to have the same thing in common: Lingering groin pain. If you play fantasy sports, this is a major headache since it seems so minor, but it can land a player on Injury Reserve on a moments notice. In real life, it is a very frustrating condition to say the least. It is hard to pin point, goes away with rest and comes back after activity, but is hardly painful enough to make you want to stop. It lingers and is always on your mind. And if you’re looking for my step-by-step sports hernia rehab video course here it is.

One the best definitions of Sport hernias is the following by Harmon:
The phenomena of chronic activity–related groin pain that it is unresponsive to conservative therapy and significantly improves with surgical repair.”

This is truly how sports hernias behave in a clinical setting. It is not uncommon for a sports hernia to be unrecognized for months and even years. Unlike your typical sports injury, most sports medicine offices have only seen a handful of cases. It’s just not on most doctors’ radar. The purpose of this article is not only to bring awareness about sports hernias, but also to educate.

Will you find quick fixes in this article for sports hernia rehab?
Nope. There is no quick fix for this condition, and if someone is trying to sell you one, they are blowing smoke up your you-know-what.

Is there a way to decrease the pain related to sports hernias?
Yes. Proper rehab and avoidance of activity for a certain period of time will assist greatly, but this will not always stop it from coming back. Pain is the first thing to go and last thing to come. Do not be fooled when you become pain-free by resting it. Pain is only one measure of improvement in your rehab. Strength, change of direction, balance and power (just to name a few) are important, since you obviously desire to play your sport again. If you wanted to be a couch potato, you would be feeling better in no time. Watching Sports Center doesn’t require any movement.

Why is this article so long?
There is a lot of information on sports hernias available to you on the web. However, much of the information is spread out all over the internet and hard for athletes to digest due to complicated terminology. This article lays out the foundational terminology you will need to understand what options you have with your injury. We will go over anatomy, biomechanics, rehab, surgery, and even the fun facts. The information I am using is from the last ten years of medical research, up until 2016. We will be making updates overtime when something new is found as well. So link to this page and share with friends. This is the best source for information on sports hernias you will find.

How Do You Know If You Have A Sports Hernia?
Typical athlete characteristics:
Male, age mid-20s
Common sports: soccer, hockey, tennis, football, field hockey
Motions involved: cutting, pivoting, kicking and sharp turns
Gradual onset

How A Sports Hernia Develops
Chronic groin pain typically happens over time, which is why with sports hernias, we do not hear many stories of feeling a “pop” or a specific moment of injury. It is the result of “overuse” mechanics stemming from a combination of inadequate strength and endurance, lack of dynamic control, movement pattern abnormalities, and discoordination of motion in the groin area.

Serious injuries, by and large, cause a lot of swelling in the knee. Especially in younger patients. Now, someone could be arthritic and they overdo it going for a big long hike and they get some swelling the next day. But rapid onset of swelling, it's like hard to make out where your kneecap is, is a pretty big cardinal sign that there's something serious that's happened to your knee. Rapid onset swelling is usually due to blood in the joint. "A meniscus that really tears and flips in the front. You tear your quad or your patellar tendon, your kneecap dislocates, you tear a little blood vessel, your ACL tears, a piece of cartilage in bone gets knocked off and causes bleeding. So a lot of the really significant injuries, people get rapid onset swelling within three to four hours and they should seek attention There's always exceptions to rules, but if your knee looks like a grapefruit, you should go get it checked.
