Cilium and flagellum structure, artwork
Cilium and flagellum structure, artwork. Cilia and flagella (collectively known as undulipodia) are hair-like protrusions from a cell membrane. They have the same structure, but cilia are generally shorter and more numerous. The core, or axoneme (left), contains 20 microtubules (white and yellow circles), arranged as a central pair surrounded by nine other pairs, or doublets. Attached to each outer doublet are two dynein arms (red). Dynein is a motor protein that converts chemical energy into a sliding movement that causes the undulipodium to beat. At the base is a basal body (grey and yellow), which is made of of nine triplets of microtubules around a hollow centre

EDITORS COMMENTS
This artwork showcases the intricate structure of cilia and flagella, hair-like protrusions found on cell membranes. Cilia and flagella, collectively known as undulipodia, play crucial roles in cellular movement and sensory functions. In this stunning print, the artist beautifully captures the detailed anatomy of these organelles. The core of both cilia and flagella is represented by the axoneme, depicted on the left side of the artwork. The axoneme consists of 20 microtubules arranged in a specific pattern: a central pair surrounded by nine other pairs or doublets. Each outer doublet is adorned with two dynein arms colored in vibrant red. These dynein arms are motor proteins responsible for converting chemical energy into a sliding motion that propels the undulipodium to beat rhythmically. At the base lies a basal body composed of nine triplets of microtubules encircling a hollow center. This structure provides stability and support to cilia and flagella. The black background enhances the visual impact of this illustration while emphasizing its scientific significance. With its meticulous attention to detail, this artwork serves as an educational tool for students and researchers alike who seek to understand more about these essential cellular components.
