1. What are the two parts of the prosencephalon?
2. what does each contain? - (CORRECT ANSWER)1. telencephalon (end brain)
- diencephalon
2. Telencephalon contains cerebral cortex, white matter, basal ganglia
- diencephalon contains thalamus, hypothalamus, and associated structures
Contents of the mesencephalon (3) - (CORRECT ANSWER)1. cerebral peduncles
- midbrain tectum
- midbrain tegmentum
1. what are the two parts of the rhombencephalon?
2. what makes up each part? - (CORRECT ANSWER)1. mentencephalon
- myelencephalon
2. pons and cerebellum make up metencephalon, medulla makes up myelencephalon
Stage 1: Neurulation
1. what 3 layers of cells make up the gastrula?
2. which of these layers makes up the entire nervous system?
1
,3. at what day does the gastrula finish forming? - (CORRECT ANSWER)1. Endoderm
- mesoderm
- ectoderm
2. ectoderm
3. day 14
Stage 1: neurulation day 21
1. The notocord is a structure within which 3 layers of cells?
2. How does the Neuroectoderm (neural plate) form?
3. how does the neural groove form? - (CORRECT ANSWER)1. mesoderm
2. The ectoderm that lies dorsomedial to the notocord thickens to become the neuroectoderm
3. Neural folds, margins lying next to the neural plate, elevate to create a depression out of the
neural plate, called the neural groove.
Neurulation day 28
1. How does the neural tube form?
2. what does the neural tube give rise to?
2
, 3. what doe the cavity of the neural tube give rise to?
4. where does the tube close off first and how does it progress?
5. what 2 events occur at the tube once it completely closes off?
6. Where are the neural crest cells and what do they give rise to? - (CORRECT ANSWER)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 (anterior 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 fails to close?
