Nucleus Solitarius

The nucleus of the solitary tract, also known as the nucleus tractus solitarius (pl solitarii) is a pair of cell bodies found in the brainstemThis structure, along with its tract (the solitary tract or tractus solitarius), has far reaching impacts on many homeostatic systems within the body.

Nucleus solitarius. Microinjections of serotonin (5HT) delivered into the nucleus tractus solitarius (NTS) elicit opposite cardiovascular effects depending on the doses used;. Blood pressure and heart rate are decreased by low doses but increased by high doses To examine this apparent contradiction, we compared cardiovascular and sympathetic nerve responses elicited in anesthetized rats by using glass. Microinjections of serotonin (5HT) delivered into the nucleus tractus solitarius (NTS) elicit opposite cardiovascular effects depending on the doses used;.

The nucleus solitarius receives fibres carrying general visceral sensations through the vagus and glossopharyngeal nerves Through those afferents, and through connections with the reticular formation, the nucleus of solitary tract plays an important role in reflex control of respiratory and cardiovascular functions. The term solitary nucleus refers to a group of cells in the medulla that is involved in the sensory component of autonomic systems that control visceral organs, such as the heart and lungs It contains numerous subnuclei, which vary by species and method of identification Classically the nucleus is divided into five subnuclei defined on the basis of topology as observed with Nissl staining. Ghrelin administration to naïve female mice caused a higher increase in food intake, growth hormone secretion, Agrp mRNA expression in the arcuate nucleus and c‐Fos expression in the nucleus tractus solitarius (NTS) than in male mice In contrast, psychological stress caused a more sustained reduction in food intake in females than males.

In the human brainstem, the solitary nucleus (SN) (nucleus of the solitary tract, nucleus solitarius, nucleus tractus solitarii) is a series of purely sensory nuclei (clusters of nerve cell bodies) forming a vertical column of grey matter embedded in the medulla oblongataThrough the center of the SN runs the solitary tract, a white bundle of nerve fibers, including fibers from the facial. The first and most important terminal of this activity is the brainstem vagal nucleus tractus solitarius Its function, on which the vagal efferent inputs that control the splanchnic organs depend, is conditioned by the level of synaptic transmission within it In conclusion, on the basis of such a view, a selective pharmacological modulation. The nucleus tractus solitarius (NTS) of the medulla receives sensory input from different systemic and central receptors (eg, baroreceptors and chemoreceptors)Neural connections from the NTS modulate the activity of sympathetic neurons located in the rostral ventrolateral medulla, and the activity of parasympathetic neurons located in the dorsal vagal nucleus and nucleus ambiguus from which.

The solitary tract (Latin tractus solitarius, or fasciculus solitarius) is a compact fiber bundle that extends longitudinally through the posterolateral region of the medullaThe solitary tract is surrounded by the nucleus of the solitary tract, and descends to the upper cervical segments of the spinal cordIt was first named by Theodor Meynert in 1872. Nucleus solitarius participates in the reflexes of the nerves innervating the nucleus, so it mediates cough reflex, carotid sinus reflex, gag reflex, and vomiting reflex The cough reflex is an involuntary protective reaction to nociceptive stimuli that serves to clear the throat from harmful objects.
