Malignant Hyperthermia Malignant Hyperthermia is primarily thought to be an autosomal dominant genetic disorder that causes a hypermetabolic state after administration of volatile anesthetics. When a patient is under anesthesia, the muscles are usually relaxed, but when a patient is experiencing Malignant Hyperthermia crisis, certain IV anesthesia causes the opposite effect. Most inhaled anesthetics other than nitrous oxide, cause or trigger Malignant Hyperthermia. More specifically, the

Cellular adaptations of growth and differentiation In order to function properly, the cells and tissues have to maintain a steady state (homeostasis)- the cells must constantly adapt cellular adaptation- is the state between a normal unstressed cell and the overstressed injured cell -by definition - an adaptative process is reversible -within defined limits, all the cells are capable of adapting to a variety of stimuli which may upset normality NORMAL CELL GROWTH -Normal tissue growth

Smooth muscle and skeletal muscle are similar yet different in many ways. The most important characteristic of smooth muscle is that it contracts involuntarily, as skeletal muscle contracts voluntarily. The splitting of ATP is much slower in smooth muscle, which causes slower contraction than what is seen in skeletal muscle, which in turn makes smooth muscle resilient to fatigue (Johnson 2013). Smooth muscle cells have a pacemaker potential, this is when the cells generate action potentials without

1. Muscle spindles - Provide sensory information about changes in muscle length and tension of muscle fibres - They primarily respond to any stretch of a muscle and, through reflex response, initiate a stronger muscle action to reduce the stretch - Two sensory afferent fibres and one motor efferent fibre services the spindle 2. Golgi Tendon Organs - Golgi tendon organ connects up to 25 extrafusual fibres near the tendon’s junction to the muscle - Golgi tendon organs discharge impulses under two

Muscular Dystrophy Disease diary #2 Today I will be explaining Muscular Dystrophy and all of the types. So let’s start off with what it is. Muscular Dystrophy is an inherited disease that causes muscles to progressively become weaker. In some forms it causes the heart and organs to weaken. Some forms only appear in men but many are in both men and women. There are eight major types of Muscular Dystrophy that I will be explaining next. So let’s move on to see what kind of Dystrophy there is. The

Clinical subjective, objective signs and symptoms of Amyotrophic Lateral Sclerosis are: difficulty walking or tripping; weakness in the leg, feet, or ankle; hand weakness or clumsiness; slurring of speech; muscle cramps or spasticity in the arms, shoulders, and tongue; difficulty holding the head up or keeping a good posture. This ailment usually begins in the hands, feet, or limbs, and then spreads to the rest of the body; as the disease advances, the muscles become weaker. Correspondingly, physicians

Using ATP To Contract Glycerinated Muscle Introduction Muscles are a fibrous bundle of tissues that contract to produce movement in the body. There are three different types of muscles, cardiac, skeletal, and smooth. Though these three different types of muscles serve slightly different purposes, they function very similarly. The main components of muscles are muscle fibers, myosin, actin, and a few more. Muscle contractions works primary off of the interaction between the proteins, actin and myosin

Introduction Duchenne muscular dystrophy, named after the neurologist who first described it, Guillaume Benjamin Amand Duchenne in the 1800, is a common type of muscular dystrophy among children, in which the muscle becomes weak and degenerates progressively. Prior to 1986, there was very little information before MDA-supported researchers succeeded in the identification of the particular gene on the X-chromosome that after mutation led to the disease (MDA, 2016). The gene was identified and named

1. Compare the three types of muscle cells and relate this to the arrangement of fibers and anatomy. There are three types of muscle cells the cardiac, the skeletal, and the smooth. The cardiac muscle is the muscle that makes up the wall of the heart. This muscle is involuntary because the contractions are not under our control. The cardiac usually have a single nucleus. The cells are often branched and are tightly connected by specialized junctions, the ends of the cells that connect to another
