Muscular Dystrophy is a disease which leads to muscle weakness and loss of strength. This disease begins at an early age and symptoms appear during the early stages of childhood and it progressively destroys and deteriorates the muscles. Among the many types of Muscular Dystrophy, the most common and severe form is Duchenne Muscular Dystrophy (DMD). Duchenne Muscular Dystrophy is an inherited disorder and unlike other forms of Muscular Dystrophy, it is the one that develops and worsens quickly…

and involves loss of muscle function. It can occur due to many different reasons such as illness, poison or trauma. Flaccid paralysis and spastic paralysis are two conditions that are considered different forms of paralysis. It can be accompanied with sensory loss as well as loss of feeling. Flaccid paralysis is the loss of muscle tone. It gives rise to limp and floppy muscles that lack firmness due to loss of activity in these muscles. Voluntary control over these muscles is lost, and that…

1. The resting membrane potential is the potential difference across the cell membrane of excitable cells such as nerve and muscle cells. The 3 major factors that establish a resting membrane potential are as follows: (1) Non-diffusible anions: The resting membrane potential is influenced by the presence of large non-diffusible anions (proteins, nucleic acids and organic phosphates) inside a cell. The presence of large non-diffusible anions inside a cell attracts a large number of cations and…

Muscular dystrophy is a type of hereditary disorder that can cause muscle weakness and can ultimately lead to the decay of skeletal muscles. A diagnosis of this disease can create a reduced quality of life and the inability to perform basic day-to-day function. Since this disease is genetic and is caused by a mutation, it is more likely for an individual to be diagnosed if a previous member of the family has had it before. The most common type of muscular dystrophy is known as Duchenne Muscualr…

Chevreul “isolated it from the basified water-extract of skeletal muscle. He later named the crystallized precipitate after the Greek word for meat, κρέας (kreas)” (Creatine wikipedia). Even though creatine was discovered back then, it was dropped and then picked back up in 1912, when Otto Folin and Willy Glover Denis from Harvard university discovered that creatine supplementation significantly enhances the amount of creatine in our skeletal muscles. Creatine has been known for the way it helps…

storage of minerals and endocrine regulation. The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions — support, movement, protection, blood cell production, calcium storage and endocrine regulation — that enable us to survive. Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that…

very well known for improving performance. Most ergogenic aids affect the metabolism and the central nervous system to reduce body fat content and stimulate protein synthesis to increase muscle mass or create lean body mass. One of the most used supplements among athletes is creatine, commonly used for increasing muscle mass. As some athletes might not even know, caffeine is also considered as a helpful ergogenic…

week! Every week, I am more amazed at how complex our bodies are. The amount of different systems, and processes needed to maintain homeostasis constantly. The complex way the body heals itself, is amazing as well. The first year of our lives, our skeletal system replaces itself 100 percent. The rest of our lives, it slows down to replacing about ten percent of itself yearly. That is a huge difference!! Bones remodel themselves in a lifelong process where mature bone tissue is removed by a…

The exhibit is set up so that one started at the skeletal system. The skeletal system showed the skeletal, the whole body bone include the ribs, large bone call femur and small bone call fibula, adult skull and infant skull. They also showed the prone bone that showed the bone disease as osteoarthritis and osteoporosis. Second system I learn is muscular system, the muscular system showed the muscular body that connect to the skeletal system. Muscles produce heat to help maintain body…

affects more than four million people in the United States alone. Scoliosis causes the spine to rotate and curve. Adolescent idiopathic scoliosis is a type of scoliosis with no known cause found in people over the age of ten. When patients reach skeletal maturity, they have instead idiopathic scoliosis as they are no longer adolescent. As adolescent idiopathic scoliosis has no known cause, it is the most scientifically important type. Without knowing a cause, doctors cannot be expected to know…
