Insights

Rabbit tongues feature fungiform papillae on the dorsal surface, apex, body, and margins. These papillae, containing taste buds, are interspersed with filiform papillae and possess a unique crest-like fold structure.

Area of Science:

  • Veterinary Anatomy
  • Histology

Background:

  • Fungiform papillae are taste structures found on mammalian tongues.
  • Understanding their distribution and morphology is crucial for comparative anatomy and gustatory research.

Purpose of the Study:

  • To describe the location and microscopic structure of fungiform papillae in adult rabbits (Oryctolagus cuniculus).

Main Methods:

  • Scanning electron microscopy (SEM) was used to examine four adult rabbit tongues.
  • Detailed observations were made on the morphology and arrangement of lingual papillae.

Main Results:

  • Fungiform papillae were identified on the dorsal tongue surface (apex and body), anterior to the torus, and on the margins.
  • They are arranged linearly, laterally to the torus, interspersed with filiform papillae.
  • The connective tissue core exhibits a base-narrow, apex-wide structure with 10-17 crest-like folds, showing impressions of taste buds and lymphatic nodules.

Conclusions:

  • Fungiform papillae in rabbits have a distinct distribution and morphology.
  • SEM analysis provides detailed insights into the structural organization of rabbit lingual papillae and associated sensory structures.

The Tongue and Taste Buds00:49

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
Taste Buds and Receptors01:20

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
Tongue01:01

Tongue

The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...
Oral Cavity01:11

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
The Hyoid Bone01:12

The Hyoid Bone

The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
Epistasis01:39

Epistasis

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
