What are the six more commonly used classifications of normal bone?
Long bones, short bones, irregular bone, flat bones, paranasal sinuses or pneumatic bones and sesamoid bones
What are the classifications given to abnormal bone stressed in spinal anatomy?
Accessory bone and Heterotopic bone
What is the name given to bone formed in a non-bone location
Heterotopic bone
What is the name given to bone formed from existing bone?
Accessory bone
What is the primary characteristic of short bones?
They are essentially cuboidal
What are examples of short bones?
Most of the bones of the carpus and tarsus
What are examples of flat bone?

What is the characteristic of pneumatic bone?
Air space within the bone
What are examples of pneumatic bone?
Frontal, ethmoid, maxilla, sphenoid, temporal
What bones contain paranasal sinuses?
Frontal, ethmoid, sphenoid, maxilla
What are characteristics of a sesmoid bone?
the bone develops WITHIN a tendon
What are consistent examples of a sesamoid bone?
Patella and pisiform
What are examples of heterotopic bone?
Calcifications in the pineal gland, heart, ligaments
What are examples of accessory bone?
Para-articular processes and bony spurs of the vertebrae
What is the characteristic feature of a long bone?
It is longer than it is across (length greater than breadth)
What are the names given to the parts of a long bone?
The diaphysis (Shaft) and typically 2 epiphyses (extremities)
What are examples of long bones?
Humerus, radius, ulna, femur, tibia, and fibula
What are flat bone?
Thin layer of spongy bone is sandwiched between to layers of compact bone
What is the name given to the spongy bone of a skull?
Diploe
What is the characteristic of irregular bone?
