Fish Vertebral Column Anatomy - Labeled Diagram and Explanation #1372340 (License: Personal Use)

This schematic shows the segmented vertebral column of a fish, with labels indicating the autocentrum (AC), neural arch (NA), haemal arch (HA), lateral trabecula (LT), and myoseptal ridge (MR). The structure illustrates how vertebrae interlock to provide flexibility and muscle attachment points essential for undulatory swimming. Grayscale shading enhances depth perception and segment differentiation.

Used in educational resources, textbooks, or online courses on ichthyology, comparative vertebrate anatomy, or evolutionary biology; supports user intent to understand fish skeletal morphology and biomechanics.
