The spelling of the word "caliciform cell" is based on the Latin word "calix" meaning "cup" or "chalice," and the suffix "-form" meaning "having the shape of." The pronunciation is [kælɪsɪfɔːm sɛl]. The stress is on the second syllable "lif," and the "i" is pronounced like "ih." The "c" in "calici" is hard, like "k." The "o" in "calici" and "cell" are pronounced like "oh." A caliciform cell is a type of glandular cell that secretes mucus in the respiratory and digestive systems.
A caliciform cell, also known as a goblet cell, is a specialized type of epithelial cell found in the lining of various organs throughout the body. The term "caliciform" refers to its goblet-like appearance, as it is shaped like an upside-down glass or chalice. These cells are primarily found in the respiratory and digestive systems, where they play important roles in protecting and lubricating the epithelial surfaces.
Caliciform cells are characterized by their unique structural features. They contain large amounts of mucin, a gel-like substance, which is secreted by the cell into the surrounding environment. The mucin often accumulates in the cytoplasm of the cell, filling its central portion and pushing the nucleus to the periphery, giving it a distinct appearance. The mucin serves various functions such as creating a protective layer against pathogens, trapping foreign particles, and aiding in the movement of substances along the epithelial surface.
These cells are crucial for maintaining the health and functionality of the respiratory and digestive systems. In the respiratory system, caliciform cells produce mucus that helps to trap and remove inhaled particles and microorganisms, preventing their entry into the lungs. In the digestive system, the mucus secreted by these cells helps to lubricate and protect the lining of the gastrointestinal tract, aiding in the smooth movement of food and protecting the epithelium from digestive enzymes.
In summary, caliciform cells are specialized epithelial cells with a goblet-like shape and are found in the respiratory and digestive systems. They secrete mucin, which plays a vital role in protecting and lubricating the epithelial surfaces in these organs.

The word "caliciform" is derived from the Latin word "calyx", which means "cup" or "chalice", and the combining form "-form", which means "shape" or "form". In the context of biology, "caliciform" indicates a cup-shaped or chalice-like structure.
The term "caliciform cell" refers to a type of cell that resembles a cup or goblet, typically characterized by a larger basal portion and a narrower apical portion. These cells are often found in epithelial tissues, particularly in the respiratory and digestive tracts, where they play a role in secreting mucus or other substances.
