For the lab test part, in this case we can do a muscle biopsy on him. A muscle biopsy is a procedure that removes a small sample of tissue for testing in a laboratory. The test can identify the disease is caused by nerve or by the muscle atrophy.
A muscle biopsy also can help us to determine the source of the disease process ensuring initiation of appropriate treatment. Muscle biopsies may be performed to diagnose neuromuscular disorders, infections that affect the muscle and other abnormalities in the muscle tissue includes MG and ALS.
Muscle biopsy is a action used to diagnose diseases involving muscle tissue. Tissue and cells from a specific muscle are evacuated and viewed microscopically. The procedure requires only a small piece of tissue to be removed from the designated muscle.

The tissue sample is obtained by inserting a biopsy needle into the muscle.
If a larger sample is required, we may make an incision in the skin (open biopsy) and remove a larger section of muscle.
The muscle selected for the biopsy depends on the location of symptoms that may include pain or weakness. The muscles often selected for sampling are the bicep (upper arm muscle), deltoid (shoulder muscle), or quadriceps (thigh muscle).
The risks are small, but may include: Bleeding, Bruising, Damage to the muscle tissue or other tissues in the area (very rare), Infection (a slight risk any time the skin is broken)
Before to do a muscle biopsy he will receive local anesthesia for a needle biopsy, and he should not feel any pain or discomfort. In some cases, he may feel some pressure in the area where the biopsy is being taken. Following the test, the area may be sore for about a week.
The process of muscle biopsy:
The patient will be asked to remove clothing and will be given a gown to
wear. During the procedure, he will need to lie as still as possible. The skin over the biopsy site will be cleansed with an antiseptic solution. The doctor injects a local anesthetic to numb the area. Doctor will insert the biopsy needle through the numbed skin and into the muscle where the sample is taken. If a larger sample is required, a small incision will be made into the skin’s surface. Sections of the muscle tissue may be cut using small, sharp scissors instead of a biopsy needle. The biopsy needle will be withdrawn and firm pressure will be applied to the biopsy site for a few minutes, until the bleeding has stopped. Our doctor will close the opening in the skin with adhesive strips or stitches, if necessary. A sterile bandage or dressing will be applied. The muscle tissue sample will be sent to the lab for examination.
James’s biopsy of his right gastrocnemius muscle would have shown a degeneration of the muscle or skeletal fibers due to the lack of dystrophyn. Another microscopic change that would be noticed is the accumulation of white blood cells. White blood cells have a very specific function which is to clear the damaged muscle fibers from the debris. Clearly, due to some of the muscle fibers being damaged other healthy fibers that have not been damaged appear denser. By having damaged muscle fibers, all the work rest upon the healthy fibers making them contract to the fullest due to the fact that the myosin and acting would have to overlap even more to make the muscle work.
The protocol and conceptual overview of these procedures can be found under the header, “Properties of Skeletal Muscle” in NPB 101L Physiology Lab Manual Second Edition (Bautista & Korber, 2009, 9-17). The test subject for this lab was the Northern Leopard frog whose spinal cord and brain were severed. In order to carry out the experiments, the materials needed were one medium length surgical scissor, two hemostats and glass dissecting probes, a nine and four inch string, a cup of Ringers saline solution with an eyedropper, and a hook electrode. The software used to analyze and record the data was the BIOPAC system.
When performing manual muscle testing for shoulder flexion or abduction, why do PTAs typically place their hand at the wrist versus mid-extremity? Think about torque and actually try it on a friend. (2 points)
They could also cause absolute devastating life long injuries, like a limp, cane, crutches or permanent devastating brain damage.
As motor neurons degenerate, this obviously means they can no longer send impulses to the muscle fibers that otherwise normally result in muscle movement. Early symptoms of ALS often include increasing muscle weakness, especially involving the arms and legs, speech, swallowing or breathing. When muscles no longer receive the messages from the motor neurons that they require to function, the muscles begin to atrophy (become smaller). Limbs begin to look thinner as muscle tissue atrophies (Choi, 1988).
Pay special attention to the face and hands, take the time to remove crusts of secretions from the eyes, nose, and mouth. The cleansing of the body includes perineal care and removal of the IV and catheter if they are present.The resident receives a new gown and new bed linens after their bath is complete. The draw sheet placement changes, meaning it is vertical instead of horizontal, so it is easier to move the resident onto the gurney. After replacing the sheets, the step of adding dentures per families request and placing a rolled towel under the chin to support the jaw to keep it closed before rigor mortis sets in. Next, closure of the eyes to the best of the Certified Nursing Assistant's ability and then combing of any stray hairs using warm water to keep them down if needed. After preparation of the resident, the next step is positioning, adjustment of the bed includes positioning it so that it is flat with the resident's arms placed straight at his or her sides. The resident's arms should lay outside of the blanket at each side of the
Moreover, I will let the patient become familiar with any instruments such as a speculum, and demonstrate the tools that will be used to obtain tissue samples that would be used during the examination. Explaining the procedure is also a significant step; this will allow the patient have a sense of control during the examination as we ask and answer questions about their current state, that would help disseminate any concern they may have. Meanwhile, they can learn about what may happen, related to any body sensations or feelings they can experience during the procedure, all while the provider continues to develop rapport and patient’s trust

The first historical account of muscular dystrophy was identified by Sir Charles Bell in 1830. He wrote about a disease that caused weakness in boys that progressively got worse. In 1836 another scientist whose name is unknown reported about two brothers who developed muscle damage, generalized weakness. Also damaged muscle was replaced with fat and connective tissue. At the time the symptoms were thought to point to tuberculosis. During the 1850s reports of boys with progressive muscle weakness became more and more common. There were also reports of these boys losing the ability to walk and dying at an early age. In the next decade French neurologist Guillaume Duchenne gave and in depth account of 13 boys who had the most common ...
...by doing an MRI to observe if muscles are inflamed, a biopsy of muscle tissue or an electromyography to test the muscle by analyzing its electric activity (The Myositis Association, 2012). The levels of muscle protein may indicate muscle irritation and can determine the diagnosis of polymyositis. When a blood test is conducted, they are looking for high levels of muscle enzymes, creatine phosphokinase and aldolase (Muscular Dystrophy Association, 2013). These enzymes are released in the bloodstream when muscles are damaged. The primary medication for polymyositis is a corticosteroid drug, which decreases the symptoms that come with the disease such as inflammation. Unfortunately polymyositis cannot be cured and there are no preventative measures for a patient to not get polymyositis because it is more of a hereditary condition (Muscular Dystrophy Association, 2013).
In some cases, symptoms and signs could point to a certain mitochondrial disease. Physical examination and laboratory tests are necessary to characterize involvement of various organs and to reach the correct diagnosis. Lab test typically include: blood tests, brain MRI or CT scans, heart tests , ophthalmological and neurological evaluations, and hearing tests. Muscle biopsy is the best way for diagnosis of many mitochondrial diseases. It requires specialized microscopic analysis and biochemical tests, such as measurements of mitochondrial respiratory chain enzyme activities.Finally, genetic testing of blood, urine, or muscle is performed to determine the exact mutation responsible for a specific
Cystoscopy. Use to remove a small sample of tissue (biopsy) for analysis in the lab. This test most likely won’t be needed if this is the first time patient had signs or symptoms of cystitis.
Muscles are very vital to the human body and as seen above mankind could not survive without this system. It helps for energy, movement, temperature stabilization, pumps blood, and keeps everything working properly as well as many more things. Muscles don’t just do it all by themselves though, muscles work with every other system in the body especially the nervous system because that is were in gets all of its impulse signals from the brain so that the muscle are able to do the things they are capable of.
The muscle tissue is a soft tissue that makes up the body. This tissue has the ability to contract which is important to the lungs. The muscle tissue surrounds the lungs that make it able for the air to be inhaled or exhaled from the lungs, an example of this muscle; it can be found in the bronchi.
