1) Circulatory System:

A: Stretch receptors in carotid sinus

Most important for short term BP reg
High BP activates the Carotid Sinus nerve
Activation of parasympathetic nervous system and inhibition of sympathetic to drop BP
Stimulation leads to decreased heart rate, decreased arterial blood pressure and decreased venous return
Increased pressure in the carotid sinus increases the discharge of efferent fibers that travel in the 9th CN
Then through local medullary circuitry, descending fibers are activated that inhibit sympathetic neurons associated with the heart
Respond to actual stretching, not chemicals

Liver:
>>Largest share of systemic CO

Kidney:
> Highest blood flow per gram of tissue

Heart:
> Large arteriovenous O2 difference
> Increased O2 demand is met by increased coronary blood flow, NOT by increased extraction of O2

TOOTH COMPOSITION & DEVELOPMENT REVIEW:

Basically everything is from Ectomesenchyme except for Enamel, which is from Ectoderm
A quick review of Odontogenesis
- Initiation
  - Induction – interaction between ectomesenchyme and epithelium
  - 6^th week
  - Formation of dental lamina
- Bud Stage
  - Proliferation – both dental lamina and underlying ectomesenchyme
  - 8^th week
  - Dental lamina into 10 buds per arch
  - Shape of tooth is evident
  - Enamel organ starts to form
  - Tooth buds of the Maxilla appear 1^st!
