Appendicular Skeleton
Bones of the limbs
Axial Skeleton
Bones of the skull, vertebral column, ribs, and sternum
Heterotopic Skeleton
Bones in unusual but normal locations
Os penis
Classification of Bone: Structure
Compact Bone
Spongy Bone
Classification of Bone: Origin
Cartilaginous Bone - Bone replaces cartilage model
Dermal Bone - Bone forms directly within a sheet of CT
Bone Development: Endochondral Ossification
Cartilaginous plates (epiphyseal plates) remain between and separate adjacent centers until the bones are mature. Bones elongate.
Bone Development: Intramembranous Ossification
No cartilage model is involved and the bones grow in diameter.
Anatomy of a Long Bone
Diaphysis - shaft
Epiphysis - end
Physis - plate of growing cartilage
Metaphysis - rapidly growing, flared segment located on diaphyseal side
Apophysis - large, bony projections which develop from independent centers of ossification
Blood Supply to Bones
Nutrient artery passes through nutrient foramen
Manus Bones
Accessory carpal bone Ulnar carpal bone Intramedial radial carpal bone Metacarpals Proximal phalanges Middle phalanges Distal phalanges
Pes Bones
Calcaneus Talus Central tarsal bone Tarsal bone (I through IV) Metatarsals
Specific Landmarks
C1 - Atlas
C2 0 Axis
C6 - Expanded ventral lamina of transverse process
C7 - Lacks transverse foramina and has caudal costal foveae
T11 - Anticlinal vertebral
Vertebral Formula
C7 T13 L7 S3 CD~20
3 Types of Joints
Fibrous
Cartilaginous
Synovial
Fibrous Joints
Little to no movement
Cartilaginous Joints
Permits only limited movement, such as compression or stretch
Synovial Joints
Freely moveable
Skeletal components not directly jointed to one another at contact surface
Basic Features of Synovial Joints
Joint cavity
Joint capsule
Synovial fluid
Articular cartilage
Articular Cartilage
Covers the articular surfaces of bones
Fibrous Layer of Joint Capsule
Blends with the periosteum at or near the margin of the articular cartilage
Ligament
A band or cord of connective tissue uniting 2 or more bones or cartilages
Tendon
A band or cord of CT that unites muscle with bone
Collateral Ligaments
Located medially and laterally
Synovial Membrane
Primary source of pain in joint diseases
