Clavicle and Scapula Humerus, Radius and Ulna Carpals, Metacarpals, Phalanges and Sesamoid Two Pelvis bones Femur, Tibia, Patella and the Fibula Tarsals and Metatarsals Bone Type Explanation Of Bone Example Of Bone Long Bones It is hard Dense They provide the strength, structure and movement for the body. They are mainly found in the upper and lower parts of the body (arms…

Introduction Myasthenia gravis is a neuromuscular autoimmune disorder that affects the skeletal muscles in the body. This disorder is mainly characterized by periods of weakness in the body. The Latin meaning for myasthenia gravis is grave muscle weakness (Lewis 2007). In the United States the prevalence rate is 14 per 100,000 (Lewis 2007) myasthenia gravis can affect any age, but normally it affects people over the age of 50 (Lewis 2007) The mortality rate from myasthenia gravis…

and 5) blood cell production. If the skeletal system did not exist, the body will break down and collapse. It consists of bones that functions as protection and sustenance to the soft tissue in the body. The bones in the body offer structure for muscles to join in order for the body to move and to not…

this children’s movement and muscle control are affected (cerebral palsy alliance, 2016). Cerebral palsy effects children in many ways, some children it effects their ability to move, balance, communicate as well as effecting the way they eat, sleep, learn and play (cerebral palsy alliance, 2016). The level of severity, the parts of the body effected and the symptoms differ from child to child. When the messengers are sent through the damage part of the brain muscles can become stiff, ridged,…

A distal transhumeral amputation typically occurs above the elbow. Cheesborough et al. suggest preserving the humerus bone segment at an approximate length of 6 to 8 cm. In addition to the length they recommend fixating the humerus at a 70 degree angle with a metal plate to give the arm rotational and leverage control when using a prosthetic arm (Cheesborough et al.,2015). In addition the shape and length of the residual humerus bone allows for increased suspension of a prosthetic arm (Tintle…

Due to the death of these motor neurons, the muscle fibres that are supplied by them undergo atrophic change. This Neuro degeneration can occur in lower and upper parts of the motor neuron systems. The primary theory behind Motor neurone disease is that, neurotransmitter glutamate causes cell injury to nerve cells by over excitation of these cells. Other…

amputees in the U.S. every year” (“Facts about Amputations”). “Limb amputation is one of the most ancient of all surgical procedures with a history of more than 2,500 years” (Phillipo). Many individuals are affected by amputations worldwide. Through thorough research on this procedure, one finds out what amputations are, different causes, the surgical process, and rehabilitation. “Amputation is the intentional surgical removal of a limb or body part” (“Amputation-Medical-dictionary”). Most of…

Duchenne muscular dystrophy (DMD) is a one type of muscular dystrophy. Muscular dystrophy is a group of genetic disorders, leading to progressive muscle degeneration. People suffering from most common muscular dystrophies ,Duchenne/Becker (DMD), Myotonic (MMD), and Limb-Girdle (LGMD), experience muscles degradation overtime, leading to overall muscle weakness and decreased mobility. Statistics show that the most prevalent forms of muscular dystrophy are rare. For example in 2007 in the…

“Myalgia” is the medical term for muscle pain. It is often a symptom of another disease present in the body. It isn't a disease itself. So patients who report having this condition to their doctor have to undergo further testing to determine what the other underlying factors are. The severity and location of the pain both help in the diagnosis too. Once the doctor has all the information that he or she needs, they can make a determination of the specific type of muscle pain that someone has, so…

Sclerosis) is a degenerative disease that affects the neurons responsible for voluntary muscle control. Motor neurons are responsible for movement and to cause movement need to receive electrochemical messages from the brain and spinal cord(the central nervous system). When the brain sends a message to the rest of your body telling it how to move, the message first starts in the brain. These neurons in the brain, called upper neurons, then send the message to the spinal cord’s lower neurons to…
