The Skeletal System
Functions
Support: The skeleton provides structural support for the body, maintaining its shape and preventing it from collapsing.
Protection: Bones protect vital organs. For example, the skull protects the brain, and the ribcage shields the heart and lungs.
Movement: Bones, in conjunction with muscles and joints, enable body movements and locomotion.
Storage: Bones store minerals, such as calcium and phosphorus, which are crucial for various physiological processes.
Blood Cell Production: The bone marrow, found within certain bones, is responsible for the production of blood cells (hematopoiesis).
Types of Bones
Long Bones: These bones, like the femur and humerus, are longer than they are wide and have a shaft and two ends.
Short Bones: Examples include the bones of the wrist (carpals) and ankle (tarsals), which are roughly cube-shaped.
-
Irregular Bones: These bones, such as the vertebrae, have complex shapes that don't fit into the other categories.

The skeletal system is a complex framework of bones, cartilage, and connective tissues that provides support, protection, and movement to the body.

Structure: The human skeleton is divided into two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton includes the skull, vertebral column, and ribcage, while the appendicular skeleton consists of the limbs and girdles.
Joints: Joints are the points where bones meet and allow for movement. They can be classified as immovable (synarthrosis), slightly movable (amphiarthrosis), or freely movable (diarthrosis).
