Pedipalps contain sensitive chemical detectors and function as taste and smell organs, supplementing those on the legs. [2] In sexually-mature male spiders, the final segment of the pedipalp, the tarsus, develops a complicated structure (sometimes called the palpal bulb or palpal organ) that is used to transfer sperm to the female seminal ...
The cephalothorax, also called prosoma, is composed of two primary surfaces: a dorsal carapace and a ventral sternum.Most external appendages on the spider are attached to the cephalothorax, including the eyes, chelicerae and other mouthparts, pedipalps and legs.
Segments or articles of the legs and pedipalps: Coxa (plural coxae): First leg segment, between body and trochanter; the coxa of the pedipalp is heavily modified to form the maxilla or endite; Trochanter: Second leg segment, between coxa and femur; Femur (plural femora): Third leg segment, between trochanter and patella
Chelicerae and pedipalps are the two pairs of appendages closest to the mouth; they vary widely in form and function and the consistent difference between them is their position in the embryo and corresponding neurons: chelicerae are deutocerebral and arise from somite 1, ahead of the mouth, while pedipalps are tritocerebral and arise from ...
Arachnids produce digestive enzymes in their stomachs, and use their pedipalps and chelicerae to pour them over their dead prey. The digestive juices rapidly turn the prey into a broth of nutrients, which the arachnid sucks into a pre-buccal cavity located immediately in front of the mouth.
Tea: a noun meaning gossip or news, the latest. e.g., "Spill the tea on your date" Thirsty: desperate for attention, or horny. Yassify: to make something over. Online, this is used ironically in ...
The latest study findings may feel a little unnerving, but Dr. Russo points out that this doesn’t mean the flu has suddenly changed. “This is something that’s been going on forever—we’re ...
The jumping spider Phidippus audax.The basal parts of the chelicerae are the two iridescent green mouthparts. The chelicerae (/ k ə ˈ l ɪ s ər iː /) are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders.
