What are the 3 types of human skeleton?
A skeletal system is necessary to support the body, protect internal organs, and allow for the movement of an organism. There are three different skeleton designs that fulfill these functions: hydrostatic skeleton, exoskeleton, and endoskeleton.
How is the human skeleton divided?
The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum.
What are the main types of skeleton?
There are two major types of skeletons: solid and fluid. Solid skeletons can be internal, called an endoskeleton, or external, called an exoskeleton, and may be further classified as pliant (elastic/movable) or rigid (hard/non-movable). Fluid skeletons are always internal.
What are the 3 main functions of the skeleton?
Function
- Allows movement: Your skeleton supports your body weight to help you stand and move.
- Produces blood cells: Bones contain bone marrow.
- Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine.
What are the main parts of human skeleton?
Axial and Appendicular Skeletons The skeleton is traditionally divided into two major parts: the axial skeleton and the appendicular skeleton, both of which are pictured in Figure 14.2. 3. The axial skeleton forms the axis of the body. It includes the skull, vertebral column (spine), and rib cage.
What are the divisions of the body?
The body is composed of ten major systems: Skeletal, Muscular, Nervous, Cardiovascular, Lymphatic, Respiratory, Digestive, Endocrine, Urinary, and Reproductive.
What are the different parts of skeleton?
The bony skeleton is divided into 2 parts: the axial skeleton and the appendicular skeleton. The axial skeleton is the central core unit, consisting of the skull, vertebrae, ribs, and sternum. The appendicular skeleton comprises the bones of the extremities.

What are three functions of the skeletal system?
The skeletal system is the body system composed of bones and cartilage and performs the following critical functions for the human body:
- supports the body.
- facilitates movement.
- protects internal organs.
- produces blood cells.
- stores and releases minerals and fat.
