Document Summary
Brains are full size by age 5 i. ii. iii. As you grow your face gets bigger but not your brain. Brain size reach the peak at age 10-12. Brain size starts to diminish around age 45 by pruning. Solidifying the circuits and getting rid of connections it does not need b. c. All cns tissue is in the ectodermal region ii. The notochord induces the neural tube which will later become the cns (spinal column the bony part) iii. Blastopore lip organizes the head and neural plate in the ectoderm i. Blastopore marks the tip of the neural plate because it"s a regulatory region e. Neural plate develops a groove, the neural groove i. ii. Everything in the center of the neural groove will become part of the cns. And everything on the edge of the neural groove will be pns f. Mesoderm produces the notochord which organizes the neural groove into the neural tube i.
