Document Summary
Lec 08 physical development and health in middle childhood (chapter 11) Primary teeth begin to fall out at about age 6. Replaced by permanent teeth at a rate of about four teeth per year for the next 5 years. Untreated oral disease may lead to problems in eating, speaking, and sleeping. Aboriginal children are more at risk and those living in low ses families. Dentist is not fully covered by government.

Cell body contains material that keeps neuron functioning. Dentrites receive inputs from other cells, send it to cell body, and out axon terminal, relays message to next neuron. Myelin sheath like an insulator, allows for faster and efficient transmission of signals. More myelin sheath and white matter, the better transmission. Axon terminal communicates with other neurons.
