The skeleton of vertebrate organisms is the framework which supports and protects the internal organs. It can be made of either bone or cartilage.
Exoskeletons and Endoskeletons are both types of skeletons. The exoskeleton, which is found most commonly on land, is an external structure like barnacles' shells and sea-snails' shells.
Skeletons are made up of individual bones that have been fused together by ligaments, muscles, and tendons. They contain marrow which is an area of bone that stores blood cells.
Although the bones in the skeleton play an important role in supporting and moving the body, they have also evolved to serve a wide range of biological functions. These include supporting the shape of an animal, protecting organs against harm, and transferring energies between bones and muscles.
A skeleton serves as an essential structure that is used by all living creatures. It also forms the basis of many other systems like muscles, tendons and internal organs. It provides protection and support for the human body, but it is also important for a variety of other animals and plants.
The skeletons of vertebrates such as humans are made up of an internal skeletal system and an external skeletal one. The internal skeletal system contains a backbone and a set of vertebrae, and the external skeleton encloses the bones of the front of the body, such as the arms and legs.
Turtles, armadillos, and certain species of sharks are animals that have an external and internal skeletal system. Some animals, like the octopus or southern giant clam have no internal skeletal system, but they do have an exoskeleton, which allows them to float on water.
Among vertebrates, the skeleton is most commonly used for structural support. The skeleton is essential for certain biological functions such as the storage and movement of blood cells.
The skeleton is divided into different layers: the periosteum, the compact bone, and the spongy bone. The periosteum shields the bone from damage.
The minerals calcium and the proteins in bones, like phosphate and calcium, form bones. They are shaped in a way that enables them to be flexed and twisted to fit around the vertebrates' backbones.
In many vertebrates like humans, the skeleton is developed from embryonic bone tissues over many years. These specialized bones have many properties that are unique to them, including a high strength and stiffness and a long bone growth cycle.
The skeleton is a part of all living organisms except for very small invertebrates. A skeleton exists in all mammals, amphibians, birds and most reptiles.
In 1928, the first Olympic skeleton competition took place in St. Moritz (Switzerland). American Jennison heaton won the gold.
Since then, the skeleton sport has been included at all Winter Games and is an Olympic event until 2022. Along with the US and Great Britain, the US has been the dominant nation in this event since 2002. They have won nine medals (three silvers and three golds).
