Ventral and dorsal are not sides. The words usually refer to gun turrets on WW2 bombers, dorsal being the top turret and ventral one underneath the fuselage.
You can tell cause dirt comes out the dorsal side. the dorsal side is darker because its the worms main blood vessel like our aorta
The dorsal side is its back, and the ventral side is its 'stomach'. The crayfish is vulnerable on its soft underbelly - the ventral side.
When parts radiate from a central point, like spokes on a wheel. The animal will have definite dorsal and ventral surfaces, but no front, back, right or left sides. ( Example: the hydra. )
The crayfish is more vulnerable to attack from it's belly or ventral side. The dorsal side has armor like plates., while the belly is mostly legs and unprotected internal organs.
Anterior. The ventral part of a person is their front. The dorsal part is their back. In quadrupeds like cats the ventral part usually faces the ground; in bipeds like people it faces the way their faces face.
The nerve cord of an earthworm is ventral because the nerve cord runs down the ventral, or belly, plane of the organism compared to a dorsal nerve cord, which would run down the dorsal, or back, plane of the organism.
The mesentery is derived from what is known in the embryo as the dorsal mesentery. The dorsal mesentery is larger than the ventral mesentery, which gradually becomes other parts of the peritoneum. Most parts of the ventral mesentery are associated with the liver. ---------------------------------------------------------Recommend if u like this.....
It's the ventral fin and My best Guess to it's purpose is that it helps stablize the forward movement in the fish, bit like the skegs on kayaks. possibly gives some direction control, like a rudder, and streamlining as well
Sounds like a pyramid
the female orca's dorsal fin is curved and the males dorsal fin is straight
2 pectoral, 2 ventral, 1 anal, 1 dorsal and 1 caudal. In total 7 fins.
Alot because dorsal means like " the back" or something, but if you mean a dorsal fin, then none, no land animals.
