Introduction Myasthenia gravis is a neuromuscular autoimmune disorder that affects the skeletal muscles in the body. This disorder is mainly characterized by periods of weakness in the body. The Latin meaning for myasthenia gravis is grave muscle weakness (Lewis 2007). In the United States the prevalence rate is 14 per 100,000 (Lewis 2007) myasthenia gravis can affect any age, but normally it affects people over the age of 50 (Lewis 2007) The mortality rate from myasthenia gravis…

She furrowed her eyebrows, widened her eyes and used exaggerated arm gestures in the direction of Aidan, as if talking with her hands to get her point across. Her flailing, large arm movements while grasping her injured arm, along with her tense facial expression and fast, loud dialect clearly portrayed her anger for Aidan’s carelessness. Once the two stopped arguing and started talking about traveling, Portu relaxed her face, angled her body towards Aidan as though intrigued by what he was…

PALSY Overview Bell's palsy is a sudden weakness and paralysis of the muscles in the face. This makes half of your facial muscles appear to tire. On that side, you may have trouble smiling or closing your eye. It is also known as facial palsy, there is no specific age of occurring. The exact cause is usually unknown, but it is assumed to be the cause of swelling, compressed and inflammation of the nerve that control of facial muscles. It might be a reaction that occurs after bacterial or viral…

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…

critical importance. The zygomatic bone provides the facial appearance, through its cheek prominence. This prominence plays an important role in the protection of the eye. Moreover, the zygomatic bone acts as a strong buttress for the absorption and transmission of masticatory forces to the base of skull. Therefore, the optimum reduction and rigid fixation is of extreme importance. 1.2 Anatomy: The zygomatic bone occupies a protuberant position in the facial skeleton and it acts as a protective…

Gravis is a disorder that causes skeletal muscle weakness. People experience the worst weakness during periods of activity and the weakness improves under periods of rest. The most common weakness is located in the muscles around the eyes. This causes blurred or double vision in the eyes. It also effects the muscles used in facial expression and chewing. These conditions can cause difficultly chewing, swallowing, and speaking. In worse conditions, the muscles used for breathing and neck and…

However, muscle fibers have vital physical features that develop two distinct types of fibers. The fast twitch, also known as type ii fibers, and slow-twitch fibers or type i fibers (Bidle, 2016). Muscles are also put in “compartments” a muscle compartment is known as, “a group of functionally related muscles enclosed and separated from others by connective tissue fascia.” (Sullivan & Gan, 2015). These fascias are also known as intermuscular septa. The muscle compartments also hold…

Introduction (Criteria 1 & 2) Bell's Palsy is a temporary drooping of the face owing to an injury to the nerves. The affected facial nerve is also referred to as the seventh cranial nerve because it is transmitted through the Fallopian canal. Although it is usually worrying, most people often recover from Bell's Palsy. Nonetheless, patients find themselves unable to control their muscles on the face. The affected side of the face starts to droop, and it can sometimes impede the production of…

Myasthenia gravis is a chronic autoimmune disease that targets the neuromuscular junction resulting in impaired impulse transmission and skeletal muscle weakness. The muscular weakness may exacerbate during periods of activity while improving after periods of rest, occurring with various severities. Muscles that control the eyes, eyelids, facial expression, swallowing, and talking can also be affected. Symptoms are presented as drooping of the eyelids, called ptosis, blurred or double vision,…
