Nervous System of Phylum Arthropoda
There is a ventral and dorsal brain in the nervous system of arthropods. The nervous system in Arthropods is a ladder-like nervous system that contains a double chain along the ventral surface. It also consists of a nerve chord that is longitudinal from the extension of lateral nerves. The nervous system in arthropods is almost similar to annelid worms. The dorsal ganglia are enough bigger than the other ganglia to be known as a mind. The neuromuscular association of arthropods is very unique from that of vertebrates, in which one neuron supplies various muscle cells, together shaping a practical motor unit.
Phylum Arthropoda
Phylum Arthropoda is the largest phylum in the Kingdom Animalia and it includes insects. Arthropoda makes up more than two-thirds of all known species worldwide. The phylum Arthropoda characteristics include jointed appendages, a well-organized body structure with a segmented design, and a tough exoskeleton made of chitin. The Arthropoda body is divided into three sections: head, thorax, and abdomen.
The Phylum Arthropoda examples include insects such as ants, and butterflies arachnids like spiders and scorpions, crustaceans such as crabs, lobsters, and shrimp, as well as myriapods including centipedes and millipedes. In this article, we will cover the Phylum Arthropoda and its classification, and characteristics in detail.
