The verticalis linguae muscle is a striated muscle of the internal tongue musculature. Its fibers are located in the anterior region of the tongue and extend from its surface to the sublingual mucosa. The muscle allows the tongue to move and is involved in food intake, swallowing, and speech. What is the verticalis linguae muscle? … Musculus Verticalis Linguae: Structure, Function & Diseases
During a muscle biopsy, physicians remove muscle tissue from skeletal muscles for the diagnosis of neuromuscular diseases, for example, in the presence of myopathies. Another task of muscle biopsy is the examination of the preserved tissue material. Closely related specialties are neurology, neuropathology, and pathology. What is muscle biopsy? During a muscle biopsy, physicians remove … Muscle Biopsy: Treatment, Effects & Risks
Rotational motion occurs as a movement on the human body, including the foot and forearm. It plays a significant role in walking and in important daily activities of the hand. What is the rotary motion? Rotational motion occurs as a movement on the human body at the foot and forearm, among other places. In the … Rotation: Function, Task & Diseases
Neurodegenerative diseases are diseases whose main characteristic is the progressive death of nerve cells. Among the best known are Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS). In addition, rarer diseases such as Creutzfeldt-Jakob disease and Huntington’s disease fall into this group. What are neurodegenerative diseases? Neurodegenerative diseases usually occur at an older age … Neurodegenerative Diseases: Causes, Symptoms & Treatment
The term contraction (Latin contrahere = to contract) is used to describe the process by which a muscle either shortens or increases its tension. There are different types of contractions with different functional significance. What is the coronary contraction? The term contraction (Latin contrahere = to contract) is used to describe the process by which … Contraction: Function, Tasks, Role & Diseases
Naltrexone is a drug in the opioid antagonist group. The prescription drug is used in opioid withdrawal. What is naltrexone? Naltrexone is used in opioid addiction withdrawal and alcohol addiction treatment. Naltrexone is an opioid antagonist. Opioid antagonists are drugs that bind to opioid receptors and can partially or completely reverse the effects of opioids. … Naltrexone: Effects, Uses & Risks
The Strümpell sign is a co-movement of the toes when the knee joint is flexed against resistance. This movement is physiologic in children under one year of age. However, in adults, it is evaluated as a pyramidal tract sign and refers to damage to the central motor neurons. What is the Strümpell sign? The Strümpell … Struempell Sign: Function, Task & Diseases
The biceps tendon reflex is an innate and monosynaptic intrinsic reflex that belongs to the stretch reflexes. Reflectively, the biceps muscle contracts after a blow to the biceps tendon, thereby flexing the forearm at the elbow joint. The biceps tendon reflex may be altered in peripheral and central nerve damage. What is the biceps tendon … Biceps Tendon Reflex: Function, Tasks, Role & Diseases
The orbicularis oris reflex is a pathologic extraneous reflex of the orbicularis oris muscle that is triggered by tapping the corners of the mouth. In neurological diagnostics, the presence of the reflex movement refers to brain-organic damage. Often, the reflex is preceded by causative ischemia in the region of the pons. What is the orbicularis … Orbicularis Oris Reflex: Function, Role & Diseases
The Oppenheim reflex, or Oppenheim sign, is a natural reflex in babies and a pathological reflex in adults. Neurology associates this reflex movement with pyramidal tract signs, as seen when central motor neurons are damaged. Diseases such as multiple sclerosis (MS) or ALS can cause such damage. What is the Oppenheim reflex? The Oppenheim reflex … Oppenheim Reflex: Function, Tasks, Role & Diseases
Saliva production or salivation occurs in the oral cavity by the numerous minor salivary glands in the oral mucosa and three major salivary glands also located in the oral cavity. Since saliva, in addition to its physical functions, also performs important biochemical tasks with regard to digestive initiation (sugar), defense against infection and relief of … Salivation (Saliva Production): Function, Tasks, Role & Diseases
The cytoskeleton consists of a dynamically variable network of three different protein filaments in the cytoplasm of cells. They provide structure, strength, and intrinsic mobility (motility) to the cell and to organizational intracellular entities such as organelles and vesicles. In some cases, the filaments project out of the cell in the form of cilia or … Cytoskeleton: Structure, Function & Diseases
