What does antennal mean?
Antennal is a technical adjective meaning 'of or relating to the antennae' — the paired sensory appendages found on insects, crustaceans, and other arthropods. It appears almost entirely within scientific writing, where researchers use it to describe structures, nerves, and functions connected with these organs: an antennal segment is a joint of the antenna itself, while the antennal lobe is the region of an insect's brain that processes smell. Because the word derives from the Latin antenna, originally a ship's yardarm before naturalists borrowed it for these feeler-like appendages, it carries a precise anatomical rather than everyday connotation. General readers will rarely need it, but for anyone studying animal sensory systems, antennal is the standard, unambiguous way to signal that something belongs to the world of the antenna.

- Of or relating to the antennae of an arthropod, especially in structure, position, or function.
"The moth's antennal receptors can detect pheromones from several kilometres away."
"Damage to the antennal nerves left the cricket unable to orient in darkness."
"Researchers mapped the antennal lobe, the insect brain's equivalent of the olfactory bulb."
An insect's antennal lobes process smells so precisely that some moths can single out one molecule of pheromone in a sea of air.

Etymology of antennal
Antennal comes from the Latin antenna, which originally referred to a spar or yardarm on a sailing ship; naturalists later applied the term to the slender, projecting sensory appendages of insects because of their resemblance to rigging poles. The adjective form developed in scientific Latin and entered English usage through zoological literature. It shares this root with related terms such as antennary, antennule, and antenniform.
How antennal is actually used
A technical term used almost exclusively in entomology, zoology, and neuroscience; rare in everyday language.
