Abstract
The taste bud is a chemoreceptive sensory organ functioning primarily for gustatory sensation. This organ, existing in the oral region of all vertebrate classes, is composed of specialized epithelial cells and nerve fibers. Extensive morphologic studies have revealed that taste buds comprise gustatory cells that form synapses with afferent sensory fibers along with other nonsynapsing sustentacular and precursor cells [e.g., 1–4]. The gustatory cells contain membrane-bound vesicles in the cytoplasm. Although these vesicles are variable in appearance and size among species, they are fundamentally categorized into small, clear and large dense-cored types. As both types of vesicles accumulate around the synaptic zone of the cytoplasm, the vesicles are considered to contain a transmitter or transmitters for the nerve.
