#1
Which type of bone cells are responsible for bone resorption?
Osteoclasts
ExplanationOsteoclasts break down bone tissue for remodeling and repair.
#2
What is the primary component of bone extracellular matrix?
Collagen
ExplanationCollagen provides strength and flexibility to bone tissue.
#3
What is the medical term for the process of bone formation?
Ossification
ExplanationOssification is the process of bone tissue formation.
#4
Which type of bone is found in the skull?
Flat bones
ExplanationFlat bones provide protection and serve as attachment sites for muscles.
#5
What is the primary function of red bone marrow?
Production of blood cells
ExplanationRed bone marrow produces red blood cells, white blood cells, and platelets.
#6
Which type of joint allows for the most movement?
Synovial joint
ExplanationSynovial joints are freely movable, allowing for a wide range of motion.
#7
Which bone cell type is responsible for bone formation?
Osteoblasts
ExplanationOsteoblasts build new bone tissue.
#8
Which hormone stimulates bone resorption?
Parathyroid hormone
ExplanationParathyroid hormone stimulates osteoclast activity.
#9
Which bone cells are responsible for sensing mechanical stress and regulating bone remodeling?
Osteocytes
ExplanationOsteocytes are key in bone homeostasis, detecting and responding to mechanical forces.
#10
What is the process by which bones increase in thickness called?
Appositional growth
ExplanationAppositional growth adds layers to the bone's surface, increasing diameter.
#11
Which vitamin is essential for calcium absorption in the intestine?
Vitamin D
ExplanationVitamin D aids in the absorption of calcium from the intestine.
#12
What is the name of the protein that forms a mesh-like framework in bone tissue?
Collagen
ExplanationCollagen provides structural support to bone tissue.
#13
Which bone disorder is characterized by a decrease in bone mineral density?
Osteoporosis
ExplanationOsteoporosis leads to weak and brittle bones.
#14
What is the name of the growth plate located near the ends of long bones?
Epiphyseal plate
ExplanationThe epiphyseal plate allows for longitudinal bone growth.
#15
Which type of bone is primarily composed of trabecular bone tissue?
Irregular bones
ExplanationIrregular bones have a spongy, trabecular structure.
#16
Which bone disorder results from excessive bone resorption followed by disorganized bone formation?
Paget's disease
ExplanationPaget's disease leads to weakened, deformed, and enlarged bones.
#17
What is the name of the bone disorder characterized by brittle and fragile bones due to defects in collagen production?
Osteogenesis imperfecta
ExplanationOsteogenesis imperfecta, or brittle bone disease, is caused by a genetic defect affecting collagen production.
#18
Which type of bone tissue is found in the shafts of long bones and forms a dense outer layer?
Compact bone
ExplanationCompact bone provides strength and support to long bones, forming the outer layer.
