Apr 8, 2024 · Learn about the structure and function of the human skeleton, the internal framework of bones and cartilages that supports, protects, and enables motion of the body. Explore the axial, appendicular, and visceral subdivisions of the skeleton and their relation to the soft parts of the body.
- The Skeletal System Consists Of More Than Bones. When you look at the human skeleton the 206 bones and 32 teeth stand out. But look closer and you’ll see even more structures.
- The Adult Human Skeleton Is Made Up of 206 Bones. These bones provide structure and protection and facilitate motion. Bones articulate to form structures.
- The Skeleton Protects Vital Organs. The brain is surrounded by bones that form part of the skull. The heart and lungs are located within the thoracic cavity, and the vertebral column provides structure and protection for the spinal cord.
- Interactions Between the Skeleton, Muscles, and Nerves Move the Body. How does the skeleton move? Muscles throughout the human body are attached to bones.
A skeleton is the structural frame that supports the body of most animals.There are several types of skeletons, including the exoskeleton, which is a rigid outer shell that holds up an organism's shape; the endoskeleton, a rigid internal frame to which the organs and soft tissues attach; and the hydroskeleton, a flexible internal structure supported by the hydrostatic pressure of body fluids.

Learn about the skeleton, the supportive framework of an animal body, in this article from Britannica. Explore the different types of skeletons, their functions, and their evolution in various animal groups.
An endoskeleton is a skeleton that consists of hard, mineralized structures located within the soft tissue of organisms. An example of a primitive endoskeletal structure is the spicules of sponges. The bones of vertebrates are composed of tissues, whereas sponges have no true tissues (Figure 38.1.1 38.1. 1 ).
Human skeleton. The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. [1] The bone mass in the skeleton makes up about 14% of the total body weight (ca. 10–11 kg for an average person) and ...
