Sucking blisters are not to be confused with leukoedema or sucking pads, as these both are often found on the baby's lips, thumb, or arm, and may be due to the sucking mechanism of the baby. Sucking pads are usually found on the border of the lips, specifically towards the inside of the mouth when looking at the line of the lip.
The cause of congenital anosmia is not fully understood, but it is often linked to the underdevelopment or absence of the olfactory bulbs and tracts. [9] Diagnosis typically involves clinical evaluation, smell tests, and imaging studies to identify any structural abnormalities in the olfactory system. [10]
The sense of taste is based on the detection of chemicals by specialized taste cells in the mouth. The mouth, throat, larynx, and esophagus all have taste buds, which are replaced every ten days. Each taste bud contains receptor cells. [21] Afferent nerves make contact with the receptor cells at the base of the taste bud. [23]
The mouth is the only place in the body which provides the sensation of taste. Due to these unique physiological features, the oral mucosa must fulfil a number of distinct functions. Protection: One of the main functions of the oral mucosa is to physically protect the underlying tissues from the mechanical forces, microbes and toxins in the ...
Taste buds are clusters of taste receptor cells, which are also known as gustatory cells. [1] The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue , soft palate , upper esophagus , the cheek , and epiglottis .
Von Ebner's glands secrete lingual lipase, [1] beginning the process of lipid hydrolysis in the mouth. These glands empty their serous secretion into the base of the moats around the foliate and circumvallate papillae. This secretion presumably flushes material from the mouth to enable the taste buds to respond rapidly to changing stimuli.

Ageusia (from negative prefix a-and Ancient Greek γεῦσις geûsis 'taste') is the loss of taste functions of the tongue, particularly the inability to detect sweetness, sourness, bitterness, saltiness, and umami (meaning 'savory taste'). It is sometimes confused with anosmia – a loss of the sense of smell.
