What bone marking is a narrow ridge of bone' usually prominent?
The crest
100
What two parts is the skeleton divided into?
Axial and Appendicular
200
What is this an image of and its cause?
OSTEOPOROSIS
- The bone resorption outpaces the bone deposit, the bone mass has declined and it becomes porous and light. The bones become fragile and are more likely to break.

What is the function of the Mitochondria?
The mitochondria produces most of the cell's energy molecules via aerobic cellular respiration.
200
What is the function of the Golgi Apparatus?
Packages, modifies, and segregates proteins for secretion from the cell, inclusion in lysosomes, and incorporation into the plasma membrane. Modifies carbohydrates on proteins.

What is the function of Ribosomes?
The site of protein synthesis?
300
What is the Epicondyle?
A raised area on or above a condyle

Cartilage Growth
What is the difference between appositional growth and interstitial growth?
Appositional grows by layering on top
Interstitial grows outwards

What are the seven functions of bones?
- Support
- Protection
- Anchorage
- Mineral storage
- Blood cell formation
- Triglyceride

What is the function of the Smooth ER?
Site of lipid and steroid (cholesterol) synthesis, lipid metabolism, drug detoxification, and Ca2+ storage.

What is a fossa?
A shallow, basinlike depression in a bone, often serving as an articular surface

Describe the 4 different bone shapes
Long bones- They are longer than they are wide
Short bones- Roughly cube shaped located in joints
Flat bones- Thin and flat
Irregular bones- Complicated shapes that don't fit into the other bone classes ex. hip bones
