Krista Smith A&P 2530 Unit 8 Case Study 1: Nick’s Story A. Prickling sensation in both feet Weak reflexes Loss of muscle tone Loss of feeling in feet Symptoms both sensory and motor B. The symptoms Nick is describing are likely caused by peripheral nerve damage; Not damage to the CNS. C. Diabetic neuropathies damage peripheral nerves. The component of the reflex that is most likely to be damaged in Nick’s situation would be the patellar reflex and the Achilles reflex. D. The division of the

Cardiac This is an involuntary muscle‚ found solely in the walls of the heart‚ as well as in the walls of the blood vessels. This sort of muscle has similarities with the skeletal muscles‚ because it is striated. Furthermore‚ it has slight similarities to the smooth muscles‚ because its contractions are not under conscious control. On the other hand this type of muscle is highly specialised. It is under the control of the autonomic nervous system‚ however‚ even without nervous imput contractions

All living organisms maintain a complex dynamic equilibrium‚ or homeostasis‚ which is constantly challenged by internal or external adverse effects‚ termed stressors.[4‚5] Thus‚ stress is defined as a state in which homeostasis is actually threatened or perceived to be so; homeostasis is re-established by a complex repertoire of behavioral and physiological adaptive responses of the organism Our biological stress response was designed for survival and is regulated by both the neural and endocrine

Donepezil It is a reversible acetylcholinesterase inhibitor which binds to peripheral anionic site not exerting only symptoms effect in the Alzheimer’s disease treatment. The drug is made by drug making companies (Eisai and Pfizer) with the trade mark Ariceft. Its main use is to treat from mild to normal Alzheimer’s disease. some studies have stated that donepezil has improved cognitive functions in patient of severe Alzheimer’s disease. The drug is found from 5 to 10 mg dose strength. And cure

A patient is admitted for electroconvulsive treatment (ECT). The physician orders the neuromuscular blocking agent metocurine iodide (Metubine) to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as Metubine‚ would interfere with muscle contraction. In order to understand how a neuromuscular blocking agent works one must first understand the process of muscle contraction and what has to take place in order for us

Diseases of the Muscular System There are over 650 muscles in the human muscular system. Each muscle has a specific role to perform. These muscles help us talk‚ walk‚ sit‚ run‚ eat‚ move about‚ hold things‚ and most important the continuous pumping of the heart muscles keeps us alive. Muscular system diseases cause many problems in the human body‚ that affects the mobility and functioning of various parts of the body. The list is very long as there are number of disorders that affect the human body

Homeostasis is the body’s ability to maintain a constant balance between the internal environment and external environment at a constant rate‚ despite changes which may affect our external environment such as body temperature and the amount of water in our bodies. By keeping this internal balance it allows our bodies to function efficiently. The negative feedback loop is produced when changes to our internal environment changes from its normal range. In this instance the brain and the nervous system

Muscular dystrophy (MD) can be described as a group of diseases that cause continuing weakness and loss of muscle mass. (Article 1‚ pg.1) Muscular dystrophy effects homeostasis because abnormal genes (mutations) interrupts the production of proteins that the body needs to form healthy muscle. (Article 1‚ pg.1) The nine major forms of muscular dystrophy are Myotonic‚ Duchenne‚ Becker‚ Limb-girdle‚ Facioscapulohumeral‚ Congenital‚ Oculopharyngeal‚ Distal‚ and Emery-dreifuss.
