Term
what are the 2 types of positions of the skeleton?
Definition
  1. appendicular skeleton
  2. axial skeleton 
Term
what is the appendicular skeleton?
Definition
includes all bones of the limbs, including the pelvic and throacic girdles
Term
what is the axial skeleton?
Definition
includes all the bones of the skull, vertbral column, ribs, sternum and cartilage running from ribs to sternum
Term
what does the Heterotorphic (visceral) skeleton include?
Definition

only the os penis

only in male dogs and never seen in male cats

determines sex of dog

Term
What are the 5 different shapes of bones?
Definition
  1. long bones
  2. flat bones
  3. short bones
  4. irregular bones
  5. sesamoid bones 
Term
What are long bones?
Definition

long in dimensions

many bones of the limbs

longer in one dimention than the other

an example is the feamour

Term
What are flat bones?
Definition

flattened in shape

ex: scapula and ribs

Term
What are short bones?
Definition

cuboidal in shape

include carpal (wrist) and tarsal (heal) bones

tiny

Term
What are irregular bones?
Definition

named by their irregular shapes

ex: those in vertebral column and pelvis

Term
What are sesamoid bones?
Definition

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

Term
What is epiphysis?
Definition

either end of a long bone

 

Term
What is diaphysis?
Definition
shaft of a long bone
Term
What is epiphyseal cartilage (growth plate)?
Definition

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

Term
What is the Cortex?
Definition

cortical and dense

tubular wall of bone surroundign the medullary cavity

hard and tough

near the outside

Term
What is the nutrient foramen and canal?
Definition
any of the opening channels in the cortex through which blood vessels pass to reach the medullary cavity
Term
What isthe periosteum?
Definition

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

 

cause pain = disturbed or fractured

Term
What is articular cartilage?
Definition

tought lubricated, softens movement

cartilage that covers the articular (joint) surfaces of bones

covers ends of bones

Term
What is compact (dense, cortical) bone?
Definition
solid bone that is found in the cortex
Term
What is spongy bone (trabecullar, cancellous)?
Definition

lacelike arrangement of boney spicules commonly found within epiphyses

 

inside the bone

bubble like structure

adds strength to inner surface of bone

Term
What are 6 protrusions or roughened areas that serve as points of attachment for muscles (i.e: areas that stick out of bone)?
Definition
  1. tubercles
  2. tuberosities
  3. trochanters
  4. epicondyles
  5. spines
  6. processes 
Term

Definition
  1. fossas
  2. foramina 
Term
What are fossas?
Definition
depressed areas (depressions) on bones
Term
What are foramina?
Definition
holes in bones
Term
What are 3 bones that are within joints and have rounded articular surfaces?
Definition
  1. condyles
  2. trochleas
  3. heads 
Term
what are 2 types of classifications of bone?
