Sublingual spray—spray for the tongue; certain human and veterinary drugs are dispensed as such. Lozenge —effects a metred and patient-controlled-rate combination of sublingual, buccal, and oral administration, as with the Actiq fentanyl .
Sublingual administration is when medication is placed under the tongue to be absorbed by the body. The word "sublingual" means "under the tongue." Buccal administration involves placement of the drug between the gums and the cheek. These medications can come in the form of tablets, films, or sprays.
The gustatory (taste) cells, which are chemoreceptors, occupy the central portion of the bud; they are spindle-shaped, and each possesses a large spherical nucleus near the middle of the cell. The peripheral end of the cell terminates at the gustatory pore in a fine hair filament, the gustatory hair.
The tongue contains taste receptors, that sends sensory information via action potential to the solitary nucleus. Then, such signal is directed towards the gustatory nucleus, which is located within the Thalamus. [12] Topography on the tongue doesn't determine the arrangement and processing of input within this nucleus.
Electrical stimulation of the insula in the human elicit gustatory sensations. Gustatory information is conveyed to the orbitofrontal cortex, the secondary gustatory cortex from the AI/FO. Studies have shown that 8% of neurons in the orbitofrontal cortex respond to taste stimuli, [ 6 ] and a part of these neurons are finely tuned to particular ...
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
Human Von Ebner's gland. Von Ebner's glands, also called Ebner's glands or gustatory glands, are exocrine glands found in the mouth. More specifically, they are serous salivary glands which reside adjacent to the moats surrounding the circumvallate and foliate papillae just anterior to the posterior third of the tongue in its submucosa, anterior to the terminal sulcus.
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
