12 year-old boy that is lactose intolerant. Broken elbow and protruding bone in upper right arm. Also fragments in arm.
Background Information
Long Bone
Diaphysis
Epiphysis
Medullary Cavity
A tubular shaft that runs between proximal and distal ends of the bone
Yellow Marrow
stored fats, can be used as energy source
mesenchymal stem cells
They can develop into bone, fat, cartilage, or muscle cells
walls are composed of compact bone
Filled with spongy bone
Wider sections of each end of bone.
red marrow fills space
Epiphyseal plate
layer of hyaline cartilage
matured cartilage is replaced with osseus tissue
epiphyseal plate is now epiphyseal line
growth plate
hematopietic
cells of bone tissue
Osteoblasts
Osteocytes
Osteogenic cells
Osteoclasts
secrete osteiods
bone forming cells
unmineralized bone matrix
mitotically active stem cells
periosteum
endosteum
Mature bone cells
respond to stimuli
communicates with osteoblasts and osteoclasts for remolding
made up of collagen
made up of calcium binding proteins
collagen makes up 90% of bone protein
breakdown of bone
Broken (right) elbow
protruding bone in upper arm
Lactose Intolerant
Bone healing
Bone production
Bone Remodeling
Inflamation
Nutrition
Dark green leafy veggies
Vitamins
Lactose- free options
Calcium supplements
increases risk
Heart disease
Kidney stones
Homeostatic set points
loss/difficulty of mobility
fractured pieces might have pierced other areas
lack of calcium, body will take from bones
causes weak bone, osteoporosis
causes mood problems
irritability
anxiety
depression
difficulty sleeping
damage to surrounding tissues
possible infection
damage to blood supply
Types of bone fractures
Comminuted
fracture in 3 or more places
spiral
ragged break occurs while twisting
depressed
broken bone that is pressed inward
compression
bone is crushed
Epiphyseal
epiphysis separates from diaphysis
Greenstick
bone breaks incompletely
running and fell forward on his arm
lack of calcium intake
epiphyseal plate
location
hyaline cartilage plate
metaphysis at each end of long bone
role
respinsible for longitudinal growth of bone
Signaling of healing process
inflammatory phase
cartilaginous Callus formation
bone Callus Formation
Remodeling Phase
Immune cells and fracture healing
Immune cell function and Origin
Hematoma formation
acts as a future template for callus formation
mesenchymal progenitor cells are recruited
calcification of fracture callus
last faze of healing repair
clot formation
tissue granulation
cell recruitment
platelets
non- nucleated cells
primary function is clotting
Supports the body
Protects organs
Produces blood cells
Maintain mineral homeostasis
Bone cells maintain homeostasis
Osteocytes
Osteoclasts
osteoblasts
Make new bone
Regulate mineral homeostasis
Dissolve mineral in bone
