The human body is the entire structure of a human being and comprises a head, neck, trunk (which includes the thorax and abdomen), two arms and hands and two legs and feet. Every part of the body is c ...
Superficial or surface anatomy is important as the study of anatomical landmarks that can be readily seen from the exterior contours of the body. It enables physicians or veterinary surgeons to gauge ...
Invertebrates constitute a vast array of living organisms ranging from the simplest unicellular eukaryotes to such complex creatures as the octopus, lobster and dragonfly. By definition, none of them ...
All vertebrates are built along the basic chordate body plan: a stiff rod running through the length of the animal (vertebral column or notochord), with a hollow tube of nervous tissue, the spinal cor ...
