ormal sperm densities range from 15 million to greater than 200 million sperm per milliliter of semen. You are considered to have a low sperm count if you have fewer than 15 million sperm per milliliter or less than 39 million sperm total per ejaculate.

Neck Examination - Cervical Spine Assessment - Clinical Skills - Dr Gill

Compose a new pain within athletes is cervical spine discomfort, thankfully in the vast majority of cases when the neck is examined the cause of the neck pain is found to be muscular.

However, pain can also refer from the neck to the arm, in which case it is important to be able to assess for cervical radiculopathy prior to gaining more information which may indicate an MRI is needed

We assess for radiculopathy by doing Spurling's test, an often overlooked part of the neck examination, but it should be included for completeness and reassurance of the patient - not forgetting the athlete or not, neck pain can be a considerable source of distress, so it's vital to be able to get information from the neck examination which allows you to safely reassure a patient when appropriate, or comment that neck exam found evidence that needs further investigation

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.

Chronic angina is a prevalent manifestation of cardiovascular disease and is most commonly due to insufficient oxygen supply from fixed epicardial lesions in the coronary arteries.

Hold your elbows at shoulder level and place the backs of your hands together with your wrists bent at 90 degrees. This position increases the pressure on the median nerve. If the test reproduces or worsens your symptoms (pain and tingling in your hands), you may have carpal tunnel syndrome.

Pancreatitis is inflammation of the pancreas. The pancreas is a gland located behind the stomach. It releases the hormones, insulin and glucagon, as well as digestive enzymes that help you digest and absorb food.

Spinal stenosis can put pressure on the spinal cord and the nerves within the spine. It commonly occurs in the neck and lower back. The condition is often caused by age-related wear and tear. Symptoms, if they occur, include pain, numbness, muscle weakness, and impaired bladder or bowel control. Treatment includes medication, physical therapy, and possibly surgery

Personality disorders are a group of mental illnesses. They involve long-term patterns of thoughts and behaviors that are unhealthy and inflexible. The behaviors cause serious problems with relationships and work. People with personality disorders have trouble dealing with everyday stresses and problems. They often have stormy relationships with other people. The cause of personality disorders is unknown. However, genes and childhood experiences may play a role. The symptoms of each personality disorder are different. They can mild or severe. People with personality disorders may have trouble realizing that they have a problem. To them, their thoughts are normal, and they often blame others for their problems. They may try to get help because of their problems with relationships and work. Treatment usually includes talk therapy and sometimes medicine.

A spinal cord injury is not the sort of thing you have to wonder about having. If you've suffered a spinal cord injury, your life is in danger, and you'll know you're injured. You can't use symptoms to diagnose the sort of spinal cord injury you have, and every patient's prognosis is different. Some make a miraculous recovery within months; others need years of physical therapy and still make little to no progress.

A pancreas transplant is a surgical procedure to place a healthy pancreas from a deceased donor into a person whose pancreas no longer functions properly. Your pancreas is an organ that lies behind the lower part of your stomach. One of its main functions is to make insulin, a hormone that regulates the absorption of sugar (glucose) into your cells. If your pancreas doesn't make enough insulin, blood sugar levels can rise to unhealthy levels, resulting in type 1 diabetes. Most pancreas transplants are done to treat type 1 diabetes. A pancreas transplant offers a potential cure for this condition. But it is typically reserved for those with serious diabetes complications, because the side effects of a pancreas transplant are significant. In some cases, pancreas transplants may also treat type 2 diabetes. Rarely, pancreas transplants may be used in the treatment of pancreatic, bile duct or other cancers. A pancreas transplant is often done in conjunction with a kidney transplant in people whose kidneys have been
