What are the steps go integument healing?

1. Hemostasis
2. Inflammation
3. Tissue repair


What is the skeletal system comprised of?

bones, cartilage, ligaments, tendons and other forms of connective tissue


What are the 3 types of ligaments?

Articular ligaments - "true ligaments" connects bone to bone
Peritoneal Ligaments - hepatodiodenial ligament, broad ligament, & the sensory ligament of the uterus
Fetal remnant ligaments - umbilical ligaments


Grazing animals have 2 large elastic ligaments in their neck called the _____

ligamentum nuchae


What are the 3 types of cartilage?

1. Hayline cartilage
2. Elastic cartilage
3. Fibrocartilage


Explain hyaline cartilage

forms most of the cartilage in an animal
Blue/white in color
The interstitial matrix in hyaline cartilage is comprised of a mixture of mucopolysaccharides and mucoproteins
Collagen fibers make up ~40% of hyaline cartilage matrix


Explain Elastic cartilage

Continuously grows
pinnae (outer ear)
Yellow cartilage
more flexible than hyaline and also contains another extracellular protein; elastin that forms meshwork fibers.


Explain fibrocartilage

found at the sites of origin and insertion of many of the larger ligaments onto bone
found within the intervertebral discs and the symphysis of the pubis and sites of bone repair.
type II collagen


What are the 2 main parts of the skeleton?

Axial skeleton
Appendicular skeleton


What is the axial skeleton comprised of?

vertebral column, ribs, sternum, and skull


What is the appendicular skeleton comprised of?

the bones of the limbs, including the pelvic girdle and scapulae


What are the skeletal functions?

1. Physical support
2. Protection of soft tissue
3. Manufactures blood cells, in the marrow cavity
4. Function in mineral storage and blood plasma ion balance
5. Facilitates movement and locomotion


Classification of bones by shape
1. _____ - longer than they are wide, with enlarged extremities bearing articular structures (femur, metacarpals)
2. _____- generally cube shaped (carpals, tarsals)
3. _____- thin and flattened (sternum, ribs, scapula)
4. _____- complex, irregular shape (vertebrae)
5. _____- small bones embedded in tendon (patella)

1. Long bones
2. Short bones
3. Flat bones
4. Irregular bones
5. Sesamoids


Mature bone is comprised of cells called _____. These lie within the matrix in small cavities called _____. which are connected via a system of fine tubules called _____.
