What is an abdomen of an insect?
An insect’s abdomen is the third functional region (tagma) of its body; the abdomen is located just behind the thorax. In most insects, the junction between thorax and abdomen is broad, but in some groups, the junction is very narrow (petiolate) giving the appearance of a “wasp-waist”.
What is the abdomen of an insect used for?
The insect body is divided into three parts: the head, thorax, and abdomen. The head is specialized for sensory input and food intake; the thorax, which is the anchor point for the legs and wings (if present), is specialized for locomotion; and the abdomen for digestion, respiration, excretion, and reproduction.
What are the body coverings of insects?
Insect Body. Insects do not have bones like you, but instead have a hard outer covering known as an exoskeleton. This exoskeleton protects their organs and gives them support for moving around. Their bodies are divided into three sections: the head, the thorax and the abdomen.
What are insect bodies called?
The three main insect body parts are head, thorax, and abdomen. The head contains the antennae, eyes, and mouthparts. The thorax is the middle body part to which the legs and wings are attached. The abdomen contains digestive and reproductive organs internally and often reproductive structures externally.
What is the bottom of a bug called?
Entomologists tend to call the top the ‘dorsal’ aspect and the bottom the ‘ventral’).
What are the 3 parts of an insect?
The basic model of an adult insect is simple: It has a body divided into three parts (head, thorax and abdomen), three pairs of legs and two pairs of wings. Insects have adopted different shapes, colours and all kinds of adaptations, but their body is almost always composed of these common elements.
What is the middle part of a bug called?
The thorax is one of the three main body parts of an insect. The thorax is the middle segment, behind the head and before the abdomen. The six legs and two pairs of wings (if present) are attached to the thorax.
Do insects have hearts?
Insects do have hearts that pump the hemolymph throughout their circulatory systems. Though these hearts are quite different from vertebrate hearts, some of the genes that direct heart development in the two groups are in fact very similar.
What is the head of a bug called?
The head can be divided into general regions (see General Insect Head Regions and Mouthparts, left): the top of the head is the vertex, the side or cheeks are gena, the front of the face is the frons, and below the frons is the clypeus. These regions may be highly modified or lost in some groups of insects.
