Since vertebrates hav vertebral column at da dorsal side thts y dey can't b DISSECTED DORSALLY, because it would b difficult to expose any of the organ system
and INVERTEBRATES don't hav vertebral column thts y dey can b dissected DORSALLY ..
Snakes are not invertebrates; they are vertebrates like all reptiles. They have a dorsal nerve cord and a spine.Snakes are vertebrates - they have a complete internal skeleton including skull, spine and ribs. Invertebrates lack any internal skeleton.
The dorsal side of a worm refers to the back or upper side of its body, opposite to the ventral side which is the belly or lower side. This orientation is typical of many invertebrates, including worms, where the dorsal side is often more pigmented or prominently marked compared to the ventral side.
Breaking it down, Median would mean in the middle, ventral has something to do with the abdomen (compare ventral and dorsal, dorsal means back), and vessel would be a duct or canal. So, it would be the canal in the middle of the abdomen.
the dorsal is along the back and is darker from the main blood stream, where as the ventral is along the front and is very light from the less blood in the certain vessel....so yeah
ventral is from the base view. so imagine a dog standing up. Dorsal would be looking down onto its back and ventral would be lokking up towards its tummy from the ground.
Probably invertebrates and vertebrates (although "chordates" is better for vertebrates) since the two groups are technically distinguished by the presence of a ventral cord in the invertebrates and a dorsal nerve cord (in their back). All but a few minor groups of chordates have their dorsal nerve cord protected by vertebrae so commonly, most people say invertebrates and vertebrates (until high school and college).
Earthworm is an invertebrate hence it has its nerve chord at the "front" of its body, that is at the ventral surface.To avoid causing damage to the nerve chord,earthworm(invertebrate)is dissected dorsal side up.

Ventral nerve cord, vertebra, dorsal nerve cord, and notocord.

The ventral side is lighter than the dorsal.
The ventral side is the opposite of the dorsal side in anatomy.
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
The opposite of it's dorsal. The Dorsal is the back, Ventral is the Front. Hence the dorsal fin on ocean-based organisms
The ventral side is lighter than the dorsal.
