Definition
-
Tergum is a noun that refers to the upper surface of the exoskeleton or external covering of an arthropod, specifically insects and crustaceans. It is generally the dorsal, or back, part of this protective body structure. The term is commonly used in entomology, the scientific study of insects, to describe the hard plate or shield-like structure that covers the thorax or abdomen of these organisms.
The tergum is a vital component of an insect's exoskeleton, providing protection and support to the internal organs. It is usually composed of a tough, rigid substance called chitin, which provides the insect with structural integrity and defense against external threats. The tergum can vary in shape and size depending on the species, serving as a distinctive characteristic used in the classification and identification of different insects.
In crustaceans, the tergum is also referred to as the carapace and fulfills a similar role of providing protection for the thorax and abdomen. It is often calcified or hardened, forming a sturdy shield that safeguards the delicate tissues underneath.
Overall, the term tergum is an important anatomical feature in the study of arthropods, highlighting the integral role of the exoskeleton in the survival and functioning of these diverse and fascinating creatures.
