| ]s display a wide variety of antennal shapes.]] | |||
| '''Antennae''' (singular '''antenna''') are paired ]s connected to the front-most ] of ]s. In ]s, they are ] and present on the first two segments of the head, with the smaller pair known as ''antennules''. All other arthropod groups, except ] and ]s which have none, have a single, ] pair of antennae. | |||
| Antennae are jointed, and generally extend forward from the head. They are ]s, although the exact nature of what they sense and how they sense it is not always clear. It appears that their function may include sensing ], air motion, heat, vibration (sound), and ] (smell or taste). | |||
| In ]s, ]s on the antennae bind to ] molecules, including ]s. The ] that possess these receptors signal this binding by sending ]s down their ]s to the ] in the ]. From there, neurons in the antennal lobes connect to ] that identify the odour. | |||
| The three basic segments of insect antennae are the ''scape'' (base), the ''pedicel'' (stem), and finally the ''flagellum'', which comprises many units known as ''flagellomeres''. | |||
