Papiller

Papiller is a term used in various contexts, primarily in the fields of medicine and biology. In medicine, papillae are small, raised areas on the surface of the body, often found in mucous membranes. They are typically found in the mouth, where they are known as frenula, and in the vagina, where they are called vestibular folds. Papillae play a role in sensory perception and may also have a role in taste and smell. In biology, papillae are projections or outgrowths from the surface of an organism, often found in sponges and cnidarians. These structures can vary in shape and size, and they may serve various functions such as filtration, attachment, or protection. In the context of the brain, papillae refer to the small, conical projections found on the surface of the cerebral hemispheres. These structures are involved in the formation of the corpus callosum, which connects the two hemispheres of the brain. Papillae are also found in the spinal cord, where they are involved in the formation of the filum terminale, a thin thread-like structure that extends from the spinal cord. In the context of the eye, papillae refer to the small, round or oval structures found in the retina, which are involved in the perception of color. In summary, papillae are structures found in various parts of the body, each with its own specific function. They are important for sensory perception, attachment, filtration, and other biological processes.
