Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
Articles should not be changed to a different spelling without a sound policy-based reason It is frequently stated that using the plural antennae for electrical aerials is incorrect. Those who say this believe that there is a grammatical rule that the plural in the context of radio is antennas and in the context of biology (insect feelers for ...
Antenna (radio), also known as an aerial, a transducer designed to transmit or receive electromagnetic (e.g., TV or radio) waves Antenna types, a list of the many different types of radio and microwave antennas
The light-harvesting complex (or antenna complex; LH or LHC) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants and cyanobacteria, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem. The antenna pigments are predominantly chlorophyll b, xanthophylls, and ...

The category of simple antennas consists of dipoles, monopoles, and loop antennas. Nearly all can be made with a single segment of wire (ignoring the break made in the wire for the feedline connection). [citation needed] Dipoles and monopoles called linear antennas (or straight wire antennas) since their radiating parts lie along a single ...
Note the antenna-bearing somite 1 was thought to be lost in Chelicerata. Formation of anterior segments across arthropod taxa based on gene expression and neuroanatomical observations, [ 10 ] [ 11 ] Note the chelicera(Ch) and chelifore(Chf) arose from somite 1 and thus correspond to the first antenna(An/An1) of other arthropods.
In the fruit fly Drosophila melanogaster and Chironomus annularius, the Johnston's organ contains almost 480 sensory neurons. [7] In the mosquito, the Johnston's organ houses ~15 000 sensory cells in males, [8] comparable to that in the human cochlea, [9] and approximately half as many in females. [10]
