only the os penis

only in male dogs and never seen in male cats

determines sex of dog

1. long bones
2. flat bones
3. short bones
4. irregular bones
5. sesamoid bones 

long in dimensions

many bones of the limbs

longer in one dimention than the other

an example is the feamour

flattened in shape

ex: scapula and ribs

cuboidal in shape

include carpal (wrist) and tarsal (heal) bones

tiny

named by their irregular shapes

ex: those in vertebral column and pelvis

tiny bones imbedded in tendons, primarily around the digital joints

ex: fabella and stiffle joint

the most visible/ biggest ones are in the stiffle joint

either end of a long bone

hyaline cartilage that separates the epiphysis from the diaphysis in growing bones

thin line = adult and growth is complete

thick line = young and still growing

cortical and dense

tubular wall of bone surroundign the medullary cavity

hard and tough

near the outside

connective tissue that covers the outer surfaces of bones except at their articulations

cause pain = disturbed or fractured

tought lubricated, softens movement

cartilage that covers the articular (joint) surfaces of bones

covers ends of bones

lacelike arrangement of boney spicules commonly found within epiphyses

inside the bone

bubble like structure

adds strength to inner surface of bone
