cilia, microvilli apical surface, lateral surface, Golgi Apparatus, nucleus, mitochondria, Basel surface, basement membrane
define anatomy and physiology
anatomy is the structure of the body and physiology is the functions of the body

3 main categories of connective tissue?
1. Connective tissue proper
- cell types with extracellular fibers in viscous
ground substance
-Grouped into loose (adipose tissue) and dense (Tendons) connective tissues
FXN: Connect and protect
2.Fluid connective tissues
- cells suspended in a watery matric that contains dissolved proteins
- Only 2 types – blood & lymph
- Fxn = Transport
3.Supporting connective tissues
- Structure: Less diverse cell types & Matrix containing much more densely packed fibers
- 2 types: Cartilage (gel matrix) and Bone (matrix of mineral deposits that provide rigidity)
What is the Olecranel on the body?
The back of the elbow
