The taste buds on the tongue sit on raised protrusions of the tongue surface called papillae. There are four types of lingual papillae; all except one contain taste buds: Fungiform papillae - as the name suggests, these are slightly mushroom-shaped if looked at in longitudinal section. These are present mostly at the dorsal surface of the ...
Lingual papillae(sg.: papilla) are small structures on the upper surface of the tonguethat give it its characteristic rough texture. The four types of papillae on the human tongue have different structures and are accordingly classified as circumvallate (or vallate), fungiform, filiform, and foliate.
There are three types of papillae involved in taste: fungiform papillae, foliate papillae, and circumvallate papillae. (The fourth type - filiform papillae do not contain taste buds). Beyond the papillae, taste receptors are also in the palate and early parts of the digestive system like the larynx and upper esophagus.
The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste (flavor). [ 1 ] Taste is the perception stimulated when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with the sense of smell ...
The papilla is a large structure at the base of the hair follicle. [4] The papilla is made up mainly of connective tissue and a capillary loop. Cell division in the papilla is either rare or non-existent. [contradictory] Around the papilla is the hair matrix. A root sheath composed of an external and internal root sheath.
Oral mucosa can be divided into three main categories based on function and histology: Lining mucosa, nonkeratinized stratified squamous epithelium, found almost everywhere else in the oral cavity, including the: Alveolar mucosa, the lining between the buccal and labial mucosae. It is a brighter red, smooth, and shiny with many blood vessels ...
The left tympanic membrane with the malleus and the chorda tympani, viewed from within the tympanic cavity (medial). Chorda tympani is a branch of the facial nerve that carries gustatory (taste) sensory innervation from the front of the tongue and parasympathetic (secretomotor) innervation to the submandibular and sublingual salivary glands.

The pulp has a background similar to that of dentin because both are derived from the dental papilla of the tooth germ. During odontogenesis, when the dentin forms around the dental papilla, the innermost tissue is considered pulp. [8] SDEO: Dental pulp of a stained and decalcified tooth. [9] There are 4 main stages of tooth development: Bud stage
