The skeleton provides support for soft tissues in vertebrate creatures and also protects their internal organs. It is composed of cartilage and/or bone.
There are two types of skeletons: endoskeletons, and exoskeletons. The first is more common on land, and it consists of a shell or external structure such as barnacles or sea snail shells.
Skeletons are made up of individual bones that have been fused together by ligaments, muscles, and tendons. These skeletons also contain the marrow of the bone, where blood is stored.
The bones of the skeleton have many other functions, which have evolved with time. This includes supporting an organism's form, protecting the organs from harm and transmitting energy between the muscles and bones.
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. The skeleton is important not only for humans, but also for other animals and plants.
Most vertebrates including humans have both an internal and external skeletal system. 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, sharks and armadillos are examples of animals with both an internal and external skeletal structure. Other animals, such as the octopus and southern giant clam, lack an internal skeletal system but have an exoskeleton that allows them to float in water.
Among vertebrates, the skeleton is most commonly used for structural support. It is important for many biological functions as well, such storing blood and moving it.
The skeleton is composed of different layers. These include the periosteum layer, the compact bones, and the spongy skeleton. The periosteum acts as a protective layer for the bones.
Bones are formed by proteins and minerals, such as calcium and phosphate. They are shaped in a way that enables them to be flexed and twisted to fit around the vertebrates' backbones.
In vertebrates such as humans, skeletons are developed from embryonic bones over a period of 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. The skeleton can be found in many mammals, birds, and amphibians as well as in some reptiles.
In 1928, St. Moritz in Switzerland hosted the first Olympic Skeleton competition. American Jennison Heaston won gold.
Since then, skeleton has been an Olympic sport until 2022 and has featured in all of the Winter Games. 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).

Traveling can be stressful. You'll often find yourself in situations where you have little time to make decisions. Prepare to be flexible.
It is possible to be stuck anywhere for hours, days or even weeks. If you have a plan, you'll be able to provide food, water, shelter and a place to rest. But, if not, you might have the need to improvise.
In these cases, you'll probably have to rely on what you know how to do best. That means making quick decisions based on instinct and experience.
But sometimes, you won't have any choice. For example, you could be stranded in an area without cell phone service, running out of gas, or having been robbed. These situations will require you to quickly adapt to the situation.
The key to success is to stay calm, remain focused and act decisively. Don't panic. Instead, focus on what you can control.
If you find yourself lost in the woods you can choose which way to go. For those who are hungry, berries and mushrooms can be eaten. If you're thirsty, you can drink rainwater or melt snow.
Rest if your tired. It's okay to bundle up if it is cold. You can wear a sweater if it's cold. Whatever you decide, you'll feel better if you stay positive.
