Type of Bones
Short Bone
Almost equal in length and width
Bones of the Wrist and Ankles
Sesamoid (round) bones
Nodular bones that develop within a tendon special type of short bone
Patella
Flat
Plate-Like shape with broad surface
Ribs, Scapula and Flattened Skull bones
Long Bone
Long with expanded ends
Arms and Leg Bones
Irregular
Varied Shape
Some Facial Bones

Bone Remodeling
Reversal
Mesenchymal stem cells, precursors to osteoblast, appear along the burrow or pit
Formation
Mature into osteoblasts at the surface of the burrow or pit
Resorption
Osteoclasts dig out a cavity, called a resorption pit, in a spongy bone or burrow a tunnel in compact
Quiescence
Site, with resting lining cells remain dormant until the next cycle
Activation
Pre-Osteoclasts are attracted to the remodeling sites
Joints (examples)
Synovial Joints
Intervertebral disc between vertebrae, helps absorb shock
Sternum and Pubic Symphysis
Connected by hyaline or fibrocartilage
Cartilaginous Joints
Free movement
Skeleton are synovial joints
Articular ends of bones in joints
Fibrous Joints
Slightly movable
Joint between the distal tibia and fibula
Immovable-Mostly sutures of the skull
Bone Names
Endochindral Bones
Cartilage replaced with bone tissue
cartilage first broken down in the diaphysis
Develop as hyaline
Bone-Resorbing is broken down
No longer grow in length
Intramembranous Bone
Sheet Like layers of connective tissue
Broad flat bones of the skull form as intramembrane bones
Stem Cells into osteoblasts bone-forming cells
Boney matrix in all directions forming spongy bone
Matrix called-Osteocytes
Anatomy of the long bone
Expands ends of the bone that forms joints with adjacent bones called epiphyses (joints)
The Long Bone Includes:
Spongy Bone
Red Bone Marrow
Articular Cartilage
Epiphyseal Line
Endosteum
Medullary Cavity
Yellow Bone Marrow
Periosteum
Diaphysis
Distal Epipysis
Movement allowed by Synovial Joints
Consists of dense connective tissue
contain shock absorbing pads
Ball and Socket = Spheroidal Joint
Hinge Joint
inner layer- synovial membrane
tendons as they slide over the bone \
Condylar= Ellipsoidal Joint
Pivot= Trochoid Joint
Free Movement
synovail fluids, luberate the joints
Classified by shape and movement
Plane=Gliding Joint
Bone Fracture Repair
Blood Vessels rupture, periosteum is likely to tear
Blood Vess. spread through damage area
Forms a Hematoma
Swelling, inflammation tissue
Large amount of mesoblast are invading hematoma
Osteoblast rapidly divide in regions close to new blood vess.
Fibroblast produce cartilage
phagocytic cells being to remove blood clot
Fills gap
Disorders
Paget disease of bone
Chronic Disease of the skeleton
thickening of cortical bone
Treatment requires
fibrous dysplasia.
Chronic problem in which scar-like tissue grows in place of normal bone
NO cure
marble bone disease (osteopetrosis)
Low blood vessel production, never function is loss, nerve paralysis
Defective function of the osteoclasts.
Breakage and makes bones dense
