sensillum

(sĕn-sĭl′əm)

n. pl. sen·silla (-sĭl′ə)

A simple sense organ of an arthropod or other invertebrate that consists of one cell or a few cells and may take the form of a hair or bristle.

sensillum

(pl. sensilla) any small sense organ or receptor (particularly in insects) used for the detection of touch, taste, smell, heat perception, sound or light perception. While most sensilla respond to stimuli from outside the body - for example, taste organs in the feeding of many butterflies and flies -some sensilla act as proprioreceptors, detecting internal changes such as the flexion of joints.
