The skeletal system is the internal framework of bones in vertebrates and includes bones, cartilage, ligaments, tendons, and joints. It consists of the axial skeleton, which supports the central axis of the body, and the appendicular skeleton, which includes the limbs and girdles. The primary functions of the skeleton are to provide support, protection, facilitate movement, store minerals, and produce blood cells.

2. Introduction
The term "skeletal" generally
relates to the skeleton,
which is the internal
framework of bones in
vertebrates.

3. The skeletal system consists of
several key parts:
1. Bones: The rigid structures
that form the skeleton,
providing support and
protection.
2. Cartilage: Flexible tissue found
in joints, the nose, and ears,
which cushions bones and aids
in movement.

3. Ligaments: Strong connective
tissues that connect bones to
other bones, stabilizing joints.
4. Tendons: Connective tissues that
attach muscles to bones,
enabling movement.
5. Joints: Areas where two or more
bones meet, allowing for various
ranges of motion.
These components work together to
support the body, protect vital organs,
and enable movement.

5. PARTS OF THE
SKELETON
1. Axial Skeleton: Comprises the
skull, vertebral column (spine),
and rib cage. It supports the
central axis of the body.
• Skull: Protects the brain and
forms the structure of the face.
• Vertebrae: Protects the spinal
cord and supports the head.
• Rib Cage: Protects the heart and
lungs.

SKELETON
2. Appendicular Skeleton: Includes
the bones of the limbs and
girdles (shoulder and pelvic).
• Shoulder Girdle: Composed of the
clavicle and scapula, connecting the
upper limbs to the body.
• Upper Limbs: Includes the humerus,
radius, and ulna, as well as the bones of
the hand.
• Pelvic Girdle: Connects the lower limbs
to the body.
• Lower Limbs: Composed of the femur,
tibia, fibula, and bones of the foot.

8. FUNCTIONS OF THE
SKELETON
• Support: Provides structure and support for
the body.
• Protection: Shields vital organs (e.g., brain,
heart).
• Movement: Works with muscles to facilitate
movement.
• Mineral Storage: Stores minerals like calcium
and phosphorus.
• Blood Cell Production: Bone marrow
produces red and white blood cells.
