Bone, Cartilage, Biomechanics & Scaling Flashcards
What is the embryonic source of fish scales?
What is the embryonic source of vertebrae?
What is the embryonic source of ribs?
What is the embryonic source of fin/limb bones?
What is the embryonic source of splanchnocranium?
What is the embryonic source of chondocranium?
Hyaline cartilage
- Glassy apperance
- Lacks abundant collagen fibrils
- Not densely packed as seen in Fibrocartilage
- Most common cartilage
Fibrocartilage
- Abundant collagen fibers
- Densely packed collagen fibers
- Collagen ribers are tensile resistant
- The strongest cartilage
Elastic cartilage
- Abundant elastic fibers
- These fibers allow for it to be springy and flexible
- Returns to its orginal shape after being bent
Which cartilage found in the sharks chondocranium, mammalian invertebral discs, and earlobes?
Fibrocartilage
Lamellar bone tissue
- orderly, regular layered arrangement of collagenous fibers within the matrix
- strength: the collegen fibers within the lamella provides tensile strength
- flexibility: the parallel and adjacent organization of collagen fibers allow for flexibility
Non-lamellar bone
- disorderly, irregular arrangement of collagen within the matrix
- temporary strength & flexibility
- randomly distributed collgen fibers
- this tissues forms rapidly in time of development or repair and provide temporary strength and flexibility until lamellar bone tissue begins to form
Haversian bone tissue
- characterized with osteons, circular arrangement of bone layers (lamella) in Haversian canals that are surrounded by collagen fibers
- these features together allow mechanical strength (resists force) and long-term durability
Characterized by its osteons and organized structure, making it well-suited for long-term structural support
Haversian bone tissue
Parallel layers of collagen fibers and provides strength and rigidity to bones
