Study Notes

Osteoblasts build new bone before undergoing apoptosis (cell death)
Fracture treatment includes reduction (realignment) and immobilization
Hematoma forms due to hemorrhaged blood clots at the site of the break
Fibrocartilaginous callus forms to span the break and connect the ends
Osteoblasts form spongy bone and replace the callus
Bone remodeling occurs
Articular cartilage covers bone ends in joints, decreases friction
Spongy bone is found in bone ends and joints, holds marrow and nutrient vessels
Compact bone is more solid and stores inorganic salts, provides bone strength
Epiphyses are bone ends that distribute pressure in joints, make RBCs
Diaphysis is the midsection of a long bone, contains spongy and compact bone
Periosteum is the outermost layer of bone, provides support and connection
Endosteum lines medullary cavity, aids in bone growth
Yellow bone marrow produces fat, red bone marrow produces blood cells
Nutrient artery carries blood and nutrients to the bone
Lower limb bones are thicker, designed for more weight and force
Wrist bones (carpals) and finger bones (phalanges) are long bones
Metacarpals anchor phalanges to the wrist
Phalanges make up fingers and enable dexterity
Femur calculation is used to estimate height
Using femur length to determine height is not accurate for all ages
Tissues of the skeletal system vary depending on slides provided
Bone names answers will vary based on student performance
Fracture results in callus formation and bone regeneration
Cancer and osteoporosis can result in bone breaks
Symptoms of a fracture include swelling, pain, bruising, and weakness
Blood clot forms at the site of the fracture, leading to swelling
Collagen forms a callus, which replaces the blood clot
Osteoblasts begin bone regeneration 6-12 weeks after a fracture
Immobilization and pain management help with fracture healing
Fractures increase risk for fractures as bone density decreases with age
By age 30, people begin to lose bone density
Prevent bone loss by getting calcium, vitamin D, and exercising regularly
