Biology Lab 9 Flashcards

Cartilage and Connective Tissues

• Elastic cartilage forms the framework of the outer ear, allowing for flexibility and shape retention.
• Adipose tissue functions as a heat insulator beneath the skin, providing thermal regulation and energy storage.
• Hyaline cartilage contributes to the flexible structure of the nasal septum, supporting the nasal passages.

Blood and Bone

• Blood consists of large amounts of fluid and lacks fibers, serving essential roles in transportation and immunity.
• Bone (compact) tissue features cells arranged around a central canal, providing structural support and housing for blood vessels.
• The bone matrix contains collagen fibers and mineral salts, contributing to its strength and rigidity.

Specialized Connective Tissues

• Areolar tissue binds the skin to underlying organs, providing support and facilitating nutrient exchange.
• Dense connective tissue is the main component of tendons and ligaments, providing strength and resisting tensile forces.
• Fibrocartilage serves as pads between vertebrae, acting as shock absorbers during movement and providing cushioning.

Additional Connective Tissue Types

• Adipose tissue also provides a stored energy supply in fat vacuoles, playing a role in metabolic regulation.
• Elastic connective tissue occurs in ligament attachments between vertebrae and artery walls, providing flexibility and resilience.
• Reticular connective tissue forms the supporting framework in the walls of the liver and spleen, aiding organ structure and function.
