Study Notes

Organs of the Skeletal System

Cartilage: Provides support and enables movement.
Bones: Form the structural framework of the body.
Joints: Act as fixed points between bones, facilitating movement.

Specific Connective Tissues

Hyaline Cartilage:
- Located at points of articulation (joints).
- Contains chondrocytes within lacunae, surrounded by extracellular matrix.
- Matrix consists of ground substance for stability and protein fibers providing elasticity and multidirectional movement.
Fibrocartilage:
- Present in intervertebral discs between vertebrae.
- Characterized by chondrocytes arranged in rows and stringy blue collagen fibers.

Perichondrium

A type of irregular collagenous connective tissue that surrounds cartilage.
Plays a vital role in the growth and repair of cartilage.

Functions of Bones

Support: Provides a framework for body tissues.
Movement: Offers muscle attachment points, acting as levers.
Protection: Safeguards internal organs.
Mineral Homeostasis: Regulates calcium levels in the body.
Blood Cell Production: Red bone marrow is responsible for generating new blood cells.
