Endoskeleton

From WikiMD's Wellnesspedia

Endoskeleton is an internal support structure of an animal, composed of mineralized tissue. Endoskeletons have functions other than supporting the body, such as facilitating movement and providing protection for internal organs.

Overview[edit | edit source]

An endoskeleton is a skeleton that is situated inside the body. The endoskeleton develops within the skin or in the deeper body tissues. The vertebrate endoskeleton is basically made up of two types of tissues (bone and cartilage). During early embryonic development the endoskeleton is composed of notochord and cartilage. The notochord in most vertebrates is replaced by the vertebral column and cartilage is replaced by bone in most adults.

Function[edit | edit source]

The endoskeleton serves many functions. It gives the body structure, provides protection for vital organs and is a place of attachment for muscles. It also allows for movement and locomotion. The endoskeleton is responsible for the human body's ability to resist gravity, maintain posture and move about.

Types of Endoskeleton[edit | edit source]

There are two main types of endoskeletons: the Hydrostatic skeleton and the Hard skeleton. The hydrostatic skeleton is found in soft-bodied animals such as earthworms and slugs, while the hard skeleton is found in animals with a hard body structure such as humans and other mammals.
