a sense organ in insects, typically consisting of a receptor organ in the integument connected to sensory neurons
Word origin
New Latin, diminutive of Latin sensus sense (Middle Latin: sense organ)
sensillum in American English

a simple sense organ usually consisting of one or a few cells at the peripheral end of a sensory nerve fiber
Word origin
[‹ NL (1895), equiv. to L sēns-, ptp. s. of sentīre to sense + -ilum dim. suffix]

The identification of the recorded sensillum requires matching the neuronal responses with known odor-response profiles.

The dendritic processes had characteristic beaded-structures and formed a twisted bundle within the sensillum.
