The tractus solitarius is a central nerve guidance pathway with a surrounded nucleus tractus solitarii. The conduction pathway plays a role primarily in the senses of taste and smell, whose sensory cells transmit signals to the central nervous system via the tractus solitarius. Reflexes such as the gag reflex fail in lesions of the conduction … Tractus Solitarius: Structure, Function & Diseases
The nucleus tractus solitarii is the neural nucleus of taste in humans and is located in the rhomboid fossa in the brain stem. Its nerve fibers connect the brain to the taste buds of the tongue as well as to the vagus nerve. Damage to the nucleus tractus solitarii – for example, from space-occupying lesions, … Nucleus Tractus Solitarii: Structure, Function & Diseases
The longitudinalis inferior muscle is one of the internal tongue muscles. Its fibers run longitudinally through the tongue and cause various tongue movements. In hypoglossal palsy, the longitudinalis muscle fails along with other tongue muscles, usually causing discomfort during swallowing and speaking. What is the inferior longitudinalis muscle? The longitudinalis inferior muscle is located in … Inferior Longitudinalis Muscle: Structure, Function & Diseases
Synonyms Medulla oblongata, bulb medullae spinalis Definition The medulla oblongata is part of the central nervous system (CNS). It is the lowest (caudal) part of the brain. The medulla oblongata is counted together with the bridge (pons) and the midbrain (mesencephalon) as part of the brain stem (truncus cerebri). The medulla oblongata contains nerve nuclei … Extended Mark
MeaningFunction A disorder of the medulla oblongata is seen, for example, in patients with a so-called bulbar paralysis. In this case the cranial nerves running in the medulla are affected. These have the innervation of the pharyngeal and pharyngeal muscles in common. Accordingly, this clinical picture leads to partial paralysis of the muscles of the … MeaningFunction | Extended Mark
