Exercise 9 Study Set Flashcards

Smooth and homogeneous.

Composed of small trabeculae (bars) of bone and lots of open space.

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.
Ex: vertebrae

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.
