ENDOSKELETON Meaning and
Definition
-
An endoskeleton refers to an internal structural framework that provides support and protection to the body of an organism. It is typically composed of bones or cartilage, which are firmly attached to various muscles, ligaments, and tendons. Unlike exoskeletons, which are found in certain invertebrates like arthropods, an endoskeleton is found primarily in vertebrates, including mammals, birds, reptiles, amphibians, and fish.
Endoskeletons play a crucial role in maintaining the shape and form of an organism, as well as providing sites for attachment and movement of muscles. They serve as a protective shield for vital organs such as the brain, heart, and lungs. Moreover, the endoskeleton framework acts as a scaffolding system, enabling the efficient distribution of the body's weight and providing stability during locomotion.
The bones or cartilage of an endoskeleton are constantly growing, developing, and remodeling throughout an organism's life. This allows for adjustments in size and proportion as the organism grows. Additionally, the endoskeleton system aids in producing blood cells through a process known as hematopoiesis, occurring mainly within bone marrow.
Overall, the endoskeleton is a vital anatomical structure that supports, protects, and enables movement in various vertebrate organisms. It is an essential characteristic that sets apart vertebrates from other groups in the animal kingdom, contributing to their remarkable adaptability and survival in diverse environments.

Etymology of ENDOSKELETON
The word "endoskeleton" has its roots in two Greek words: "endo" meaning "within" or "inner", and "skeleton" meaning "dried-up body" or "framework". The term was coined in the mid-19th century, combining these two elements to describe the internal structural support system found in certain animals, including humans.
