1. telencephalon (end brain)
- diencephalon
1. What are the two parts of the prosencephalon?
2. Telencephalon contains cerebral cortex, white matter,
2. what does each contain? basal ganglia
- diencephalon contains thalamus, hypothalamus, and as-
sociated structures
1. cerebral peduncles
Contents of the mesencephalon (3) - midbrain tectum
- midbrain tegmentum
1. mentencephalon
1. what are the two parts of the rhombencephalon? - myelencephalon
2. what makes up each part? 2. pons and cerebellum make up metencephalon, medulla
makes up myelencephalon
Stage 1: Neurulation
1. Endoderm
- mesoderm
1. what 3 layers of cells make up the gastrula?
- ectoderm
2. which of these layers makes up the entire nervous
2. ectoderm
system?
3. day 14
3. at what day does the gastrula finish forming?
Stage 1: neurulation day 21 1. mesoderm
1. The notocord is a structure within which 3 layers of 2. The ectoderm that lies dorsomedial to the notocord
cells? thickens to become the neuroectoderm
2. How does the Neuroectoderm (neural plate) form? 3. Neural folds, margins lying next to the neural plate,
elevate to create a depression out of the neural plate,
3. how does the neural groove form? called the neural groove.

1. When the edges of the neural crest fuse together
2. the entire CNS
3. the ventricular system
4. closes off in thoracic region first, then moves caudally,
then cranially
5. the tube separates from the overlying ectoderm
- ends of the neural tube remain open for 2 weeks (ante-
rior and posterior neuropore)
6. sit at the top of the neural tube and give rise to
- dorsal root ganglia
- cranial nerve ganglia
- autonomic ganglia
- schwann cells
1. what defect happens when the posterior neuropore
1. spina bifida
fails to close?
2. anencephaly
2. what defect happens when the anterior neuropore fails
- portions of the brain that don't develop
to close?
Formation of major vesicles from neural tube:
1. cranial end
1. which end (cranial or caudual) expands quicker?
2. prosencephalon
- mesencephalon
2. What are the 3 primary vesicles that form at the cranial
- rhombencephalon
end?
1. What are the subdivisions
(secondary vesicles) of the prosencephalon? (2)
2. What do these subdivisions give rise to (what are their
derivatives?)
