Muscle Pain, Adult Muscle pain (myalgia) may be caused by many things, including: • Overuse or muscle strain, especially if you are not in shape. This is the most common cause of muscle pain. • Injury. • Bruises. • Viruses, such as the flu. • Infectious diseases. • A chronic condition that causes muscle tenderness, fatigue, and headache (fibromyalgia). • A condition, such as lupus, in which the body’s disease-fighting system attacks other organs in the body (autoimmune disease).…

coronectomy might be a better option, here’s why and what you need to know. Nerve Complications The roots of wisdom teeth, in the lower jaw, often press on or wrap around the nerves that supply feeling to your tongue, lip and chin. And in these cases, where the roots are in close proximity to either the lingual nerve (LN) or the inferior alveolar nerve (IAN), the dental website exodontia.info warns that surgical extraction can cause nerve damage, leaving you with temporary or permanent loss of…

Introduction: In the orthopedic field, local anesthesia for lower-extremity surgeries or nerve block methods intending pain control has been growing Objectives: In this study, the appropriateness of nerve blocks in arthroscopic knee surgery was investigated. It has been informed that pain, anxiety and et cetera can increase BP by stimulating sympathetic nervous system. Then the appropriateness of nerve blocks for knee joint diseases was verified by relation of the pain during surgery, the…

1. The number of muscle fibers that are innervated by a motor neuron is dependent on what muscle it is. Fine motor movements, such as typing, would need only a few muscle fibers. This means that the thumb has only a few fibers, but the thigh, back, and biceps have many. These need a lot more force to be exerted, which is why they need more muscle fibers. Using your thumb and bladder does not require many muscle fibers. 2. Alpha motor neurons innervate extrafusal muscles but gamma motor neurons…

Electrical stimulation: Eight self-adhesive 7x13 cm oval carbon electrodes were adhered to the skin over the quadriceps and hamstring muscles (four electrodes per leg). These muscles were selected because of their ease of access, clinical importance, and large size, which we reasoned would yield the greatest potential for altering energy expenditure. The distal margin of the distal quadriceps electrode was placed over the distal-most palpable border of the vastus lateralis. The proximal…

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,…

Introduction: Planarians are free-living aquatic flatworms that posses remarkable regeneration abilities in addition to its distinct negative phototaxis behavior. A wealth of research studies has thoroughly examined its photophobic behavior under different wave frequencies and light conditions. Planarian are highly sensitive to white light and wavelengths of high frequencies, blue-green range ( Paskin TR, 2014). Two basic pigment-cup eyes situated in the head region govern its photophobic…

that the paralysis arose from the nerve sheath becoming thickened and compressed in stylomastoid foramen. The cold hypothesis, or paralysis e frigore, maintained that exposure to draughts produced the palsy. Exposure to cold or drafts considered as the primary cause of Bell's palsy. Cobb and Coggeshall38 hypothesized:-Edema of a nerve trunk may interrupt passage of the nerve impulses along axons, especially if the oedema happens to be a point at which the nerve is passing through a bony canal…

Essay Peripheral Nerve Disorder Most of Peripheral Nervous System’s disorders are cause by neuritis which is an inflammation in the branch, Neuralgia a nerve pain, Peripheral neuropathy – a nerve disease or damage, and some are hereditary. Peripheral Nervous System (PNS) has a lot of nerve fibers (branches) that extends from spinal cord to the other part of the body and sends signal to the Central Nervous System (CNS). This includes the “special senses” of touch, smell, hearing, taste, sight and…
