    What is connective tissue?

    Essential for binding and supporting other tissues.

    What are the roles of connective tissue?

    Includes protection, insulation, and transportation.

    What are the main elements of connective tissue?

    Composed of ground substance, fibers, and cells.

    How does dense connective tissue differ from loose connective tissue?

    Dense tissue resists tension; loose provides storage and immunity.

    What characterizes cartilage?

    Avascular nature limits its healing capacity.

    What are the types of cartilage?

    Includes hyaline, fibrocartilage, and elastic cartilage.

    What is the function of blood as connective tissue?

    Transports nutrients and waste products throughout the body.

    What are the two types of bone?

    Compact bone and spongy bone.

    What is the primary function of the skeleton?

    Provides support, protection, and facilitates movement.

    What is the composition of bone?

    Made of collagen and minerals like calcium and phosphate.

    How are bones classified?

    Based on their shape and function.

    What defines long bones?

    Longer than wide, primarily compact with spongy ends.

    What are short bones?

    About the same length on all sides, mostly spongy.

    What characterizes flat bones?

    Thin, curved, with large surfaces for muscle attachment.

    What are irregular bones?

    Complex shapes, mainly spongy with a thin compact layer.

    What are sesamoid bones?

    Bones found within tendons that help distribute force.

    What is the structure of a long bone?

    Includes epiphysis at both ends and a diaphysis shaft.

    What is the periosteum?

    A membrane that contains blood vessels and nerves around bones.

    What is the Haversion system?

    A network of passageways for nerves and blood vessels in bone.

    What is the function of the endosteum?

    It covers the inner layer of compact bone and contains osteoblasts and osteoclasts.

    How does the medullary cavity differ between infants and adults?

    Infants have red bone marrow for RBC production, while adults have yellow bone marrow for fat storage.

    What happens to yellow bone marrow during anemia?

    It converts to red bone marrow to increase RBC production.

    What is the role of articular cartilage?

    It absorbs stress and reduces friction at joint surfaces.

    What distinguishes spongy bone from compact bone?

    Spongy bone has an irregular arrangement called trabeculae and contains red bone marrow.

    What does the epiphyseal line indicate?

    It is a remnant of the growth plate where longitudinal growth ceases.

    At what age does the epiphyseal plate typically fuse in males?

    Around 21 years.

    At what age does the epiphyseal plate typically fuse in females?

    Around 18 years.
