The hinge ligament is a flexible structure that connects the two halves (valves) of a clam shell at the hinge. It acts as a spring to allow the shell to open and close. When the adductor muscles relax, the hinge ligament helps the clam's shell to open.
Hinge ligament :)
its the doorhinge of the clam (where it excretes poopoo)
This is from Wikipedia:Bivalves have a shell consisting of two asymmetrically rounded halves called valves that are mirror images of each other, joined at one edge by a flexible ligament called the hinge.
Bivalve mollusks like clams hold their shells closed with their muscular bodies. They also have leathery "hinges" at the rounded part of the shell which help to hold the two halves together. These are similar to ligaments in higher animals. If you ever get a clam in the supermarket that is already open, that one is dead and you should not eat it.
The hinge ligament hold the two shells together as well as the adductor muscles which controls the opening and closing of the bivalve.
Clams close their shells with powerful adductor muscles which pull the two valves together. A springy ligament at the hinge pulls the shell open when the muscles relax. Just like us, the clam needs to use nerve cells to signal the muscle to do its thing.
its uses gilles for respiration and they can only move by shooting water through their hinge and propelling forward
No, "clam" is a casual term for a mollusk; a filter-feeder type of freshwater or marine animal that has two calcareous shells (valves) joined near a hinge with a flexible ligament. Arthropods are invertebrate animals that have an exoskeleton (external skeleton), segmented body, and jointed appendages (legs), such as spiders (arachnids) or lobsters (crustaceans).
Some stoves are referred to as clam shells because they resemble the form and function of the shells of a clam. They are compact with hinge joining two halves.
To determine the right and left valves of the clam, put the valve in your hand with the nacre facing you and the beak pointing up. If the beak is toward the right, it is the left valve, and if it is toward the left, it is the right valve.
The umbo, also known as the beak, is the oldest part of a clam shell. It is the point where growth starts and forms the center of the shell. Over time, new layers of shell material are added, extending outwards from the umbo.
