What is the role of the nucleus of the tractus solitarius?
Nucleus tractus solitarius is involved in generating and synchronizing the peristaltic activity of the upper gastrointestinal tract during swallowing. The rhythmic release of inhibitory (GABA) and excitatory (glutamate) neurotransmitters is responsible for the sequential motor pattern seen in peristalsis.
What is the nucleus of tractus Solitarius?
The nucleus of tractus solitarius, also known as the nucleus of the solitary tract or simply the solitary nucleus, is a purely sensory nucleus located in the dorsolateral medulla oblongata and lower pons.
Where does the NTS project to?
Brain Stem The NTS integrates multiple autonomic reflexes and projects to other central autonomic regions. Neurons in the reticular formation of the ventrolateral medulla are arranged in distinct groups that maintain cardiomotor, vasomotor, and respiratory functions.
What is NTS respiratory?
The NTS is the first synaptic station of the cardiorespiratory afferent inputs, including peripheral chemoreceptors, baroreceptors and pulmonary stretch receptors.
Where is the mesencephalic nucleus located?
The mesencephalic nucleus is a paired structure located at the mesopontine junction which projects cephalad through the midbrain. It is situated along the anterolateral aspect of the periaqueductal grey matter and lies ventral to the inferior colliculi at the level of the midbrain.
Which nucleus receives impulses of taste?
Anatomical terms of neuroanatomy The gustatory nucleus is the rostral part of the solitary nucleus located in the medulla. The gustatory nucleus is associated with the sense of taste and has two sections, the rostral and lateral regions.
Where is the nucleus Ambiguus located?
Its location is in the reticular formation of the medulla oblongata, the lowest part of the brainstem. The nuclei are in the lateral regions of the rostral medulla posterior to the inferior olive. The nucleus ambiguus is involved in the motor functions of swallowing and speech.
What is mesencephalic?
Midbrain, also called mesencephalon, region of the developing vertebrate brain that is composed of the tectum and tegmentum. The midbrain serves important functions in motor movement, particularly movements of the eye, and in auditory and visual processing.
What is the trigeminal pathway?
The spinal trigeminal pathway is considered to be the cranial homologue of the spinothalamic pathway: That is, it carries information about crude touch, temperature and pain from the head and face. In the medulla, the spinothalamic tract lies near the lateral surface just posterior to the inferior olive.
