Cartilage
Hyaline cartilage
True/False: Phalanges are long bones
True
What bone is porous and light and contains red bone marrow?
Spongy bone
Which secretes bone matrix to external bone?
Osteoblasts
Which hormone is produced body cells of the thyroid gland and respond to high levels of blood calcium?
Calcitonin
Where is elastic cartilage found?
Ear and epiglottis
Cube shaped OR as short as they are wide.
What is the mesh of bony spines in the spongy bone called?
Trabeculae
What is the purpose of osteocytes?
They survey and alert the osteoblast or osteoclasts to build or destroy bone matrix. OR Negative feedback response in the bone
What does parathyroid hormone do to the blood calcium levels and the bone?
What gives Fibrocartilage it's great tensile strength?
Thick collagen fibers
Which bone classification is described as thin, and slightly curved?
Flat bones
What is 1 difference and 1 similarity between the periosteum and the endosteum?
Difference: Periosteum covers the outside of compact bone while endosteum covers the inside of the compact bone
Similarity: They both are in the diaphysis OR both are connective tissue membranes
List the 5 zones of the Epiphyseal plate
1. Resting Zone
2. Proliferation (growth) zone
3. Hypertrophic zone
4. Calcification zone
5. Ossification zone
Describe the difference between hypocalcemia and hypercalcemia
Hypocalcemia - low levels of calcium cause hyperexcitability
Hypercalcemia - high levels of calcium cause nonresponsiveness
Which cartilage is found in between the vertebra, in the pubic symphysis and the minisci of the knee?
Fibrocartilage
What bone classification does the coccyx fall under?
Irregular bone
Where is articular cartilage found?
Ends of long bones OR the Epiphysis
Which zone is filled with older chondrocytes and begin to form interconnecting spaces when lacunae enlarge and erode?
Hypertrophic zone
What are the 4 major stages of fracture repair?
1. Hematoma forms, 2. Fibrocartilaginous callus forms, 3. Bony callus forms, 4. Bone remodeling occurs
Which cartilage contains collagen fibers only?
Hyaline cartilage
Name a bone that is classified as a sesamoid bone.
Patella
When does the epiphyseal line stop growing?
After puberty OR in adulthood OR females age 18, males age 21
Describe the process of bone remodeling.
As the bone grows in length, remodeling maintaining the bone's shape. OR The bone grows appositionally by replacing old bone and growing the epiphyseal plate.
What is the difference between appositional growth and interstitial growth?
Appositional is thickness (wideness) of bone and Interstitial is length (longitudinal) growth of bone.
