Muscle atrophy

neuro-muscular disease affecting people over fifty, mostly males, is characterized by progressive muscle weakness and atrophy in key muscles in the arms (forearm flexors) and the legs (quadriceps), resulting in severe disability. IBM is generally a slowly progressive disease and life expectancy isn’t significantly affected. Ted was diagnosed with IBM in 2012 when he was 68 years old, but his muscle biopsy showed that he has had it 10 to 15 years prior to the diagnosis. This displays the slow…

Myotonic Dystrophy is an autosomal dominantly inherited disorder at which an individual has the inability to relax his or her muscles; thus progressing to muscle degeneration and decrease muscle tone [1]. Currently there are two types of muscular dystrophy that are known in the both the medical and scientific community. There’s type one myotonic dystrophy also known as congenital myotonic dystrophy which has an onset at birth. Then there is type two, myotonic muscular dystrophy which has an…

denser muscles as when you create micro-tears in the muscles, the body overcompensates by making new muscle fibres. This leads to stronger muscles, this is called adaptation. Adaptation is changing to your environment/ the stresses and strains placed upon the body. Also when you begin training your central nervous system can be improved as the body…

neuromuscular factors, the loss of neural input to the muscles is ongoing and a lifelong process that is irreversible. When the body loses motor units that innervate several muscle fibers, the neurons that survived attempt to “adopt” muscle fibers. The lower number of motor units functional means the individual has decreased strength and muscle atrophy. The vastus lateralis in 43 male cadavers aged 15 to 83, this study showed total number of muscle fibers was reduced by 50% between the age…

particularly the brain and nervous system and muscles. The signs and symptoms of the disorder mostly begin to present themselves in childhood following a period of normal development, but can begin at any age. Early symptoms may include muscle pain and weakness, headaches, loss of appetite, nausea and vomiting, and seizures. Almost all affected individuals experience stroke-like incidents beginning before the age of 40. These episodes frequently involve temporary muscle weakness on one side of…

The anatomy is quite complex but as for functionality, facial nerve is involved in the movements of muscles related to facial expression and laryngeal muscles. While testing, the patients are asked to give facial expressions. Cranial nerve VIII is a sensory nerve is responsible for hearing and senses of equilibrium. Although this more relates to speech and hearing but the testing…

optimal performance. "True Hydration" reduces cramping and increases power throughout strenuous activity, giving you maximum physical benefits. The addition of Branched Chain Amino Acids supports muscle function, growth and recovery. BCAA loading while training keeps muscles primed and avoids muscle atrophy that comes from overexertion without proper feeding. Amino Hydrates unique combination assists athletes in performing at their peak longer, without post training exhaustion. it's a…

Changes in Tissue Homeostasis of the Elderly That Result in Altered Cognitive; Motor Abilities. As we age, homeostasis is harder to achieve within all of our cells. The cardiac muscle tissue and the walls of the blood vessels thicken, decreasing the amount of oxygen and nutrients that is pumped out to the entire body. The thickness of the blood vessels makes it hard for nutrients to enter the other tissues body, and for wastes to leave these tissues. Water is also harder to retain…

Symptoms including weakness and wasting of hand muscles, and numbness in the hand. Disputed TOS is caused by injury to the nerves in the brachial plexus. The most prominent symptom of the disorder is pain and other symptoms include weakness and fatigue. Venous is generally rare that affects men and women…

Spinal muscular atrophy (SMA) is inherited disorder that affects the lower motor neuron in the anterior horn cells of the spinal cord and brain stem resulting in progressive weakness of the skeletal muscles [1]. It is considered as one of the most common autosomal recessive diseases and leading genetic cause of death during childhood [2]. The primary cause of SMA is mutation of the spinal motor neuron 1 (SMA1) while the severity of the disease is determined by the number of identical spinal…
