Exercise 9 Study Set Flashcards
Compact Bone is?
Smooth and homogeneous.
Spongy (or cancellous) bone is?
Composed of small trabeculae (bars) of bone and lots of open space.
What are the 4 groups of bones?
Long, Short, Flat, and Irregular bones.
Typically cube shaped, and they contain more spongy bone than compact bone.
Ex: tarsals and carpals
Are much longer than they are wide, generally consisting of a shaft with heads at either end. They are composed predominantly of compact bone.
Ex: femur and phalanges.
Generally thin, with two waferlike layers of compact bone sandwiching a layer of spongy bone between them. Many flat bones are curved.
Ex: bones of the skull.
Bones that do not fall into one of the other categories.
Identify the diaphysis or shaft of a long bone.
Provides a sturdy support with some resilience or "give". Most skeletal cartilages are composed of this cartilage.
Much more flexible than hyaline cartilage, and it tolerates repeated bending better. Only found in the external ear and the epiglottis.
Consists of two rows of chondrocytes alternating with rows of thick collagen fibers. It has great tensile strength and can withstand heavy compression, is used to construct the intervertebral discs and the cartilages withing the knee joint.
Site of blood cell formation?
Red marrow cavity
Major submembranous site of osteoclasts?
Scientific term for bone shaft?
Contains fat in adult bones?
Growth plate remnant?
Major submembranous site of osteoblasts?
Contains spongy bone is adults?
Serves as an attachment point for muscles and bones through tendons and ligaments?
Layers of bony matrix around a central canal?
Site of osteocytes?
Longitudinal canal carrying blood vessels, lymphatics, and nerves?
Minute canals connecting osteocytes of an osteon?
Inorganic salts deposited in organic ground substance?
