What is the medulla oblongata? The medulla oblongata (myelencephalon, afterbrain) is the lowest and rearmost area of the brain. After transition from the spinal cord, it thickens in an onion shape and ends at the bridge. The myelencephalon contains cranial nerve nuclei and is thus the origin of cranial nerves VII to XII, which emerge … Medulla Oblongata: Structure and Function
The aryepiglottic fold is counted as part of the pharynx in humans. It is a mucosal fold. It is vibrated in during laryngeal singing. What is the aryepiglottic fold? The aryepiglottic fold is called the plica aryepiglottica. It is associated with the medulla oblongata in medicine. The medulla oblongate is approximately 3 cm long. Downward, … Aryepiglottic Fold: Structure, Function & Diseases
The anterior vagal trunk is a nerve branch of the vagus nerve involved in parasympathetic innervation of the stomach and liver. Thus, the visceromotor fibers of the nerve control portions of involuntary organ activity. Failure of the anterior vagal trunk leads to dysregulation of the liver and stomach. What is the anterior vagal trunk? The … Truncus Vagalis Anterior: Structure, Function & Diseases
Diagnostics Due to the characteristic clinical picture of an epidural hematoma, the diagnosis is often abbreviated. The doctor’s knowledge and interpretation can be supported or confirmed by imaging techniques. The clinical picture is characterized by the staggered symptomatology and the uneven pupil size. In addition, the unilateral loss of various bodily functions and the progressive … Diagnostics | Epidural hematoma
Effect on spine and spinal cord There is naturally not much space in the spine. The spinal cord fills most of the space with the surrounding cerebrospinal fluid. If a haematoma occurs due to bleeding in the epidural space, this can quickly affect the spinal cord. While initial pressure can be very painful, but is … Effect on spine and spinal cord | Epidural hematoma
Prognosis Due to the serious complications, the mortality rate for epidural hematomas is relatively high. Even if the relief surgery is performed and the bruise is removed, the patient dies in 30 to 40% of cases. If the patient survives the injury, there is the question of consequential or late damage. A fifth of all … Prognosis | Epidural hematoma
An epidural hematoma is a bruise that is located in the epidural space. It is located between the outermost meninges, the dura mater, and the skull bone. Normally, this space does not exist in the head and is only caused by pathological changes, such as bleeding. The situation is different in the spine: here the … Epidural hematoma
To PDA/PDK Epidural anaesthesia (PDA) is a procedure in which the anaesthetic is injected directly into the epidural space (also called the epidural space). For a single administration of the drug, a needle is inserted between the vertebral bodies and the anesthetic is injected directly. If the duration of the drug treatment is to last … To PDA/PDK | Epidural hematoma
Bulbar brain syndrome is a complication of midbrain syndrome. Such a syndrome results from compression of brain structures following increases in intracranial pressure within the middle cranial fossa. While midbrain syndrome is usually reversible, bulbar brain syndrome is at high risk for final brain death. What is bulbar brain syndrome? With the exception of the … Bulbar Brain Syndrome: Causes, Symptoms & Treatment
Reactive movements are motor responses to physical and mental stimuli that are distinct from spontaneous movements. Essentially, reactive movements are based on the stretch-shortening cycle that occurs when muscles are actively lengthened. Reactive force is subject to disturbances in neurogenic lesions of the extrapyramidal system. What are reactive movements? Reactive movements usually correspond to rapid … Reactive Movements: Function, Task & Diseases
The Jacobson anastomosis is a bundle of nerve fibers in the head and skull region. Its fiber course is responsible for parasympathetic excitation (innervation) of the parotid gland. These nerve connections were discovered by the Jewish-Danish physician and researcher Ludwig Levin Jacobson (1783-1843). They originate in the nucleus salivatorius inferior, a cranial nerve nucleus in … Jacobson Anastomosis: Structure, Function & Diseases
The medulla oblongata is the most caudally located part of the brain and is also known as the medulla. This brain region is best known as the center of respiration, reflexes, and blood circulation. Failures of the medulla oblongata are associated with brain death and can cause bulbar brain syndrome, midbrain syndrome, or apallic syndrome. … Medulla Oblongata: Structure, Function & Diseases
