Taste Buds Anatomy

Taste gustation the surface of the tongue along with the rest of the oral cavity is lined by a stratified squamous epithelium. Generally taste buds fungiform circumvallate and foliate papillae are innervated by sensory neurons of the 7th facial and 9th glossopharyngeal cranial nerves ganglia whose axons transfer taste input from peripheral taste buds to the hindbrain.

Fungiform papillae as the name suggests these are slightly mushroom shaped if looked.

Taste buds anatomy. Each taste bud consists of 30 100 taste receptor cells. Circumvallate papillae there. Anatomy of taste taste is a component of our daily life and gives our food character.

Slender processes microvilli extend from the outer ends of the receptor cells through the taste pore where the processes are covered by the mucus that lines the oral cavity. Then these taste buds send their sensory information through neurons to the gustatory center of the brain. One end of the taste each taste receptor cell is exposed to the oral cavity and has microvilli on its surface to increase contact with stimuli.

The taste buds are the sensory end organs for gustation see the images below. Foliate papillae these are ridges and grooves towards the posterior part. The way we taste is through our nose and our oral cavity which send chemical information from our taste buds and olfactory epithelium to our brain for processing.

There are three types of lingual papillae that contain taste buds present on the human tongue. In mammals taste buds contain approximately 50 100 elongated epithelial cells and a small number of proliferative basal cells. A receptor cell has a microvilli called a taste hair protruding through a pore on the apical surface of the taste bud.

These hairs are the receptor surface for taste stimuli. Vallate foliate and fungiform. Taste receptor cells are long thin cells oriented perpendicular to the surface of the tongue.

In the surface of the tongue are raised bumps called papilla that contain the taste buds. The taste buds are embedded in the epithelium of the tongue and make contact with the outside environment through a taste pore. The taste buds are sensory taste receptors found on the tongue throat and palate that help form the perception of taste.

There are approximately 50 receptor cells in each taste bud. Taste buds detect chemicals dissolved in saliva from food in the mouth and throat. Each bud is flask shaped with a wide base and a short neck opening at the taste pore.

There are three types of papilla based on their appearance.
