from the dorsal side
My teacher said is the ventral.
Anatomically, the ventrum is a location, the underbelly area on the ventral abdomen.
The ventral nerve cord runs throughout an earthworm's body. When they start to branch from ganglion the nerve cords are still present throughout the segments.
Upper part darker, can see venation more clearly. Upper part (ventral) originates from xylem. Lower part (dorsal) originates from phloem. Do not confuse with other denominations of dorsal/ventral.
Members of phylum Arthropoda have segmented bodies, external skeletons, jointed appendages; have rigid body structures made mostly of bio-mineralized alpha-chitin. They must shed their exoskeleton in order to grow. They have repeated body segments with leg or appendage pairs, ventral nerve cords with paired ganglia in each segment. They are bilaterally symmetrical with compound eyes and an internal body cavity with an open circulatory system.

A plate of cartilage, or a series of bony or cartilaginous plates or segments, in the median line of the pectoral skeleton of most vertebrates above fishes; the breastbone., The ventral part of any one of the somites of an arthropod.
The Characteristics of Arthropods are : 1) Segmented body plan 2) Exoskeleton composed of chitin 3) Paired jointed appendages on variable number of segments 4) Dorsal heart with paired ostia (openings) 5) Hemocoelic body cavity (open circulatory system) 6) Nervous system comprised of a dorsal brain and ventral nerve chord
no
ventral, i think...
no
Arthropods, which fall under the phylum of Arthropoda, encompass many animals such as spiders, insects, crustaceans, centipedes, and scorpions. One characteristic of arthropods is their exoskeleton, which they have because they are invertebrates and do not have any internal bones to support them. Other characteristics of arthropods include their segmented bodies, bilateral symmetry, open circulatory system, and jointed appendages.
The sternum is anterior to the heart (in front of the heart). It may also be called superficial or ventral to the heart.
