Skeletal System
Fill in the skeletal body on the back page of your packet. Use
pages 134 in your text book.
IntroductionHow many bones do you think are in the human
body?206Largest Bone?FemurSmallest Bone?Ossicles (ear bones)
Functions (5)1.Support Body
2. Protect organs
3. Attachment of muscles
4. HemopoiesesThe bones make blood cells from embryonic month 5
on
5. Mineral StorageCa2(PO4)3
AnatomyThere are basically four types of bones.
1. Long Bonese.g.FemurRadiusulnahumerus
2. Short bonescarpals
3. Flat Bones
4. Irregular Bones
Parts of a long bonePlease color code the femur. Color code
letters a-g.
EpiphysisA. Ends of the bone (Proximal and distal)
Epiphyseal plateA1: Cartilage growth plates on bone ends.(Growth
plate)
(hyaline) cartilage on end of bone b bone trabeculae of spongy
bone c red marrow cavity d epiphyseal plate (hyaline cartilage)
a Epiphyseal plate made of hyaline cartilage is responsible for
long bone growth. Note: The direction of growth is toward the
diaphysis (shaft of long bone). Also Note: The newly forming spongy
bone (below the growth plate) is not clearly organized as the older
spongy bone in the epiphysis above the growth plate.
DiaphysisB. Shaft of the bone, middle part.
Articular CartilageC. Cartilage layer to reduce pain and
friction.
PeriosteumD. Living layer surrounding bone. Nourishing and
growth in width.
Spongy boneLooks like a sponge.Mostly in the epiphysisContains
red marrow (Makes RBCs)
Compact BoneClose together in diaphysis.Organized into
concentric layers.
Medullary CavityHole in the middle of the bone.Filled with
yellow marrow (fat for energy storage)
