Front 1

List the 3 stages of neural tube formation

Back 1

Neural plate, neural groove, neural tube

Front 2

What structure is responsible for the induction of neurulation?

Back 2

The notochord

Front 3

List the derivatives of neural crest in the nervous system.

Back 3

Ectomesenchyme; spinal, sympathetic and parasympathetic ganglia; Schwann cells; pigment cells

Front 4

Define neurulation.

Back 4

Formation of the neural tube and eventual formation of the central nervous system

Front 5

List the three initial swellings of the neural tube.

Back 5

Prosencephalon (forebrain), mesencephalon (midbrain), and rhombencephalon (hindbrain)

Front 6

What specific structure is responsible for inducing the formation of the
prosencephalon?

Back 6

The prechordal plate lying beneath the neural tube

Front 7

List the 3 flexures of the developing nervous system.

Back 7

Cervical, pontine, telecephalic

Front 8

Which three regions of the developing CNS form the brain stem?

Back 8

Myelencephalon, metencephalon, mesencephalon

Front 9

List the cephalic enlargements of the neural tube, their divisions and what each division forms in the fully developed brain.

Back 9

Prosencephalon – telecephalon (cerebrum) and diencephalon (thalamus/hypothalamus); Mesencephalon – mesencephalo n (substantia nigra, basal ganglia); Rhombencephalon – metencephalon (pons & cerebellum) and myelencephalon (medulla oblongata).

Front 10

Which region of the three vesicle stage of CNS development eventually develops the least?

Back 10

The mesencepahlon, joins the diencephalon (thalamus/hypothalamus rostrally) and the metencephalon (pons) caudally.
