Fused segments in an arthropd are called tagmate and phenomenon is called tagmatization . Cephalothorax , Prosoa , meta soma etc. are tagmata .
Fused segments of the sacrum indicate the presence of sacralization, a condition where the lower lumbar vertebrae fuse with the sacrum, or the natural fusion of the sacral vertebrae themselves, which typically occurs during development. This anatomical feature can affect spinal mobility and stability, potentially leading to lower back pain or discomfort. In some cases, it may also influence nerve function in the pelvic region.
The animal with a segmented body is called an arthropod.
A snail would not be classified as an arthropod; it is a mollusk. A starfish, on the other hand, is classified as an echinoderm, not an arthropod either. Arthropods include organisms like insects, arachnids, and crustaceans, characterized by their exoskeletons and segmented bodies. Therefore, neither the starfish nor the snail is an arthropod.
The fairyfly, a type of parasitic wasp, is considered the smallest arthropod. These tiny insects can measure around 0.139 mm in length.
congruent line segments- line segments that have the same lengths.
The tagma of a crayfish is the Cephalothorax because it is made of two fused segments. The tagma of a crayfish is the Cephalothorax because it is made of two fused segments.
'Jointed legs'. Think of the segments and hinges in their legs. :)
1. Head 2.Thorax 3.Abdomen
Insects have body Sections but Arthopods have body Segments.
Three body parts{segments } of Arthropods are head , thorax and abdomen .Technically these are called tagma and they are made up of segments .
you know the segment's in an insect's body depends on the type of the insect
As opposed to earthworms, arthropods (crayfish) segments often become fused. Therefore, certain parts of a crayfish that looks like one piece, was once multiple pieces before they became fused together, so some segments were actually once more than just that one segment. An earthworm on the other hand, is just as many segments as are seen, and always has been.
Biramous
Arthropod skeletons differ from ours in that they are external, or exoskeletons. By contrast ours are internal, or endoskeletons.
19 segments. The head is composed of six fused segments and is attached to the thorax. The thorax consists of three segments. The abdomen, posterior to the thorax, is made up of ten complete segments.
