12 Questions
Match the following types of cartilage with their composition:
Hyaline cartilage = Predominantly collagen fibers Fibrocartilage = Predominantly collagen fibers with thick bundles Elastic cartilage = Predominantly elastin fibers Articular cartilage = Lines the surface of articulating bones
Match the following methods of cartilage formation with their descriptions:
Interstitial growth = Chondrocytes within lacunae divide and secrete new matrix, expanding the cartilage from within Appositional growth = New chondrocytes and matrix are added on the surface of existing cartilage
Match the following bone components with their characteristics:
Osteoblasts = Bone-forming cells that secrete matrix Osteocytes = Mature bone cells that maintain bone structure Extracellular matrix of bone = Mainly composed of collagen fibers and calcium salts Blood supply in bone = Well-vascularized to support metabolic activity
Match the following bone types with their descriptions:
Immature bone (woven bone) = Irregular arrangement of collagen fibers, formed quickly during fracture repair Mature bone (lamellar bone) = Organized into parallel layers for strength and support
Match the following facts about bone and cartilage with their correct statement:
Bone metabolism = Very active due to good blood supply Cartilage metabolism = Not very active as it lacks a good blood supply Bone healing capability = Usually heals well due to its blood supply Cartilage healing capability = Does not heal well due to poor blood supply
Match the following functions of cartilage with their descriptions:
Supporting framework of organs = Provides structural support for certain body parts Growth and development template for long bones = Forms a model for ossification during skeletal growth
Match the type of cartilage with its primary location:
Hyaline cartilage = Articular surfaces of joints, large respiratory passages, rib-sternum junction Elastic cartilage = Pinna of ear, external auditory canal, epiglottis Fibrocartilage = Intervertebral discs
Match the component with its role in the cartilage extracellular matrix:
Collagen fibers = Provides structural support GAGs and proteoglycans = Makes the ECM firm and resistant to mechanical forces Type I collagen fibers in perichondrium = Contributes to avascularity of cartilage
Match the cell type with its description:
Chondroblasts = Precursor cells that differentiate into chondrocytes Chondrocytes = Mature cartilage cells that lie in little artifactual lacunae Fibroblasts in perichondrium = Contributes to the formation of dense connective tissue
Match the characteristic with the correct type of cartilage:
Most common type of cartilage = Hyaline cartilage Located in areas that are pliable and flexible = Elastic cartilage Located in areas subjected to pulling forces = Fibrocartilage
Match the function with the corresponding type of cartilage:
Support soft tissue, line joints, growth of long bones = Hyaline cartilage Located in areas subjected to pulling forces = Fibrocartilage Functions as support and flexibility in specific body parts = Elastic cartilage
Match the structural feature with the correct type of cartilage:
Contains Type II collagen fibers = Hyaline cartilage Contains Type II collagen fibers and elastic fibers = Elastic cartilage Contains Type I collagen fibers = Fibrocartilage
Explore the functions, composition, and formation methods of cartilage and bone. Compare and contrast the three types of cartilage and immature/mature bone. Dive into the cells, extracellular matrix, and formation processes of both cartilage and bone.
