Every year, thousands of people, mostly young children, are affected by the neuromuscular disease Muscular Dystrophy. There are many different types of Muscular Dystrophy and they differ based on which muscles are affected and what the causative protein in the body is. Muscular Dystrophy was first introduced to us in 1830 by Sir Charles Bell, who wrote of an illness that caused a great amount of weakness in young boys. Years later, a French neurologist by the name of Guillaume Duchenne…

Worth the Risk? Performance Enhancing Drugs (PEDs) are substances used to improve any form of performance in humans and boost self-confidence. Athletes and bodybuilders take PEDs. Military personnel use them to enhance combat performance. PEDs came along in the beginning of the Olympics Games (776-393 BC) because athletes were concentrated on winning. Many athletes wanted the edge over their rivals and wanted to make sure their performance was going to be the best it could be. A growing…

Code Blue-Where To? This is a review of the case study Code Blue-Where To?, The patient in this case is an 80 year old patient admitted to a psychiatric facility, who ultimately dies. His death is not the fault of the medical staff, but the care he received prior to his death was plagued with system errors and communication breakdowns that could be argued as causing undue patient harm. The errors include problems with staff training, policy and procedures, outdated equipment, and failure to…

implementing the overall policies, procedures, and services of the cardiac catheterization lab. A cardiac cath lab director ensures efficient and effective lab operations, including quality control and compliance adherence. The director must be familiar with a variety of the field 's concepts, practices, and procedures and relies on extensive experience and judgment to plan and accomplish goals. Leads and directs the work of others ("Cardiac Catheter Director Roles," 2016, p. 5). To obtain…

Evaluate the anatomical and physiological similarities and differences between skeletal, cardiac, and smooth muscle. Skeletal Muscles are attached to bones. Their functions include: produce skeletal movement, maintain posture and body position, support soft tissues, guard body entrances and exits, maintain body temperature, and store nutrients. They are striated muscles because of their appearances of having bands of actin and myosin that form the sarcomere which is located in the myofibrils.…

Exercise is very general word. There are hundred types of exercises, and they are for different reasons. For example, there are sports for avoiding diseases, building bodies, or entertainment(1). However, each one of them is important. Three aspects about exercise that will be highlighted are The definition of exercise, similarities between two exercises, and differences between another two exercises. The first aspect that will be discussed is the definition of exercise. Exercise…

The All-or-none law is the principle that the strength by which a nerve or muscle fiber responds to a stimulus is independent of the strength of the stimulus. If that stimulus exceeds the threshold potential, the nerve or muscle fiber will give a complete response; otherwise, there is no response. It was first established by the American physiologist Henry Pickering Bowditch in 1871 for the contraction of heart muscle. According to him, describing the relation of response to stimulus, “An…

1.3.2 Papillary dermis The papillary dermis is the smaller of the two layers in the dermis, and is located between the epidermis and the reticular dermis. The papillary dermis is approximately 300-400 µm deep, depending on the age and anatomical location.22 The upper outermost layer of the papillary dermis is arranged into protruding structures called the dermal papillae. The dermal papillae contains microvascular and neural components to support the epidermis. The dermal papillae increase the…

From the time of birth to adulthood, the amount of bones in the human body decreases as they are amalgamated together to construct larger and sturdier bones. Adults have two hundred and six bones in the body; On the other hand, babies are born with approximately three hundred bones. The axial skeleton consists of eighty bones, which are part of the skull, hyoid bone, vertebral column and thoracic cage. Additionally, the appendicular skeleton consists of one hundred and twenty six bones that are…

Case Study: Hereditary Canine Spinal Muscular Atrophy Genetic Background Hereditary canine spinal muscular atrophy (HCSMA) is proven to be an autosomal-dominate disease that affects most noticeably the Brittany spaniel (Pinter MJ, Waldeck RF, Wallace N, & Cork LC, Motor Unit Behavior in Canine Motor Neuron Disease, 1995). HCSMA originated as a spontaneous mutation in the Survivor Motor Neutron gene found in the purebred Brittany spaniel population (Ericsson. A & Rubin. C, 2012). Due to the…
