Do spiders have necks

Spiders do not have teeth. Instead, they have two chelicerae, each with two segments, the fang and the basal portion. The fang, the organic functional equivalent to a hypodermic needle is what penetrates the skin, fur, or exoskeleton of the spider's target - spider mouthparts are primarily intended for envenoming a spider's prey in most species, typically insects and other small arthropods; not for biting humans. The basal portion includes all or part of the spider's venom glands, which can be squeezed under voluntary control by the spider to force venom out of the glands and into the wound
