Upgraded B004 Ntbi2201 Early Vertebrate Embryonic Similarities

Upgraded B004 Ntbi2201 Early Vertebrate Embryonic Similarities — a labelled NEET Biology diagram with a definitions lexicon.

Diagram showing early vertebrate embryonic similarities. Labelled parts: Cross-section, Gill Slits, Class, Gills, pharyngeal arches. A diagrammatic view of an organ or tissue obtained by cutting it at a right angle to its longitudinal axis. FYI: Transverse sections (T.S.) are standard in plant anatomy to study the arrangement of vascular bundles. Individual openings to the gills found in the pharyngeal region of chordates, used for respiration and filter feeding. FYI: In cartilaginous fish, gill slits are separate and exposed, whereas in bony fish, they are covered by a bony flap called the operculum. A taxonomic rank that consists of one or more related orders sharing common structural and developmental characteristics. FYI: For example, Class Mammalia includes diverse orders such as Primata (humans/monkeys) and Carnivora (lions/dogs). Thin, folded structures found in the respiratory system of aquatic organisms, such as fish and bivalves, used for gas exchange. FYI: In fish, the gills are housed within the operculum and are crucial for maintaining the necessary oxygen levels in aquatic environments. pharyngeal arches is a labeled feature or concept in this upgraded BioAtlas image: A diagram comparing the cross-section of a developing embryo at an early stage, highlighting shared features like gill slits (pharyngeal arches) across different classes of vert...
