Answer 1

Ventral: Pertaining to the front or anterior of any structure. The ventral surfaces of the body include the chest, abdomen, shins, palms, and soles. Ventral is as opposed to dorsal. From the Latin "venter" meaning belly. These two terms refer to back (dorsal) and front or belly (ventral) of an organism. The dorsal (from Latin dorsum, meaning 'back') surface of an organism refers to the back, or upper side, of an organism.
