Pedicel

Definition

A slender, stalk-like structure that connects different parts of an organism, particularly connecting the main body to smaller structures. In spiders, it connects the cephalothorax and the abdomen.

Etymology

From Latin 'pediculus', meaning 'little foot', a diminutive of 'pēs', meaning 'foot'.

Example
