- In anatomy, toward the dorsum or back; backward, with reference to the animal itself, without regard to its posture: as, the spinal cord lies dorsad of the bodies of the vertebræ; the aorta arches dorsad as well as sinistrad: opposed to ventrad, and in Vertebrata equivalent to neurad.
Anal operculum: the dorsal arch of the 10th abdominal segment; in caterpillars = supra-anal plate, q.v. Anal organs: Collembola; the two modified hairs arising from a tubercle ventro-cephalad of the anus and usually curving caudo-dorsad.
Caudo-dorsad: directed upward and toward the tail.
Frontal fastigium: in Orthoptera, that process of the face extending dorsad between the antennae and meeting or nearly meeting the fastigium of the vertex in Tettigidae.
Lying a short distance dorsad to the pharynx are seen two small, thick-walled openings, _ty_; these are the rudiments of the thymus glands.
While the trachea and bronchi lie ventrad to the oesophagus, the lungs lie laterad and even dorsad to the oesophagus and cardiac end of the stomach.
