🗑
|

| Q: The ventricular zone (also called the ependymal layer or neuroepithelial layer) lies adjacent to _______. | A: The lumen of the neural tube.
🗑
|
||||
| Q: These cells proliferate to produce neuroblasts. | A: Neuroepithelial cells.
🗑
|
||||
| Q: Neuroblasts migrate peripherally to form _______. | A: The mantle layer or zone.
🗑
|
||||
| Q: OK, we know the mantle a layer is made up of neuroblasts… so what do these become. | A: Neuroblasts are the precursor of gray matter.
🗑
|
||||
| Q: In the spinal cord and brain stem where would you find the mantle layer? | A: In the spinal cord and brain stem the mantle layer immediately overlies the ventricular zone.
🗑
|
||||
| Q: What establishes the marginal layer? | A: Growing neuronal fibers which later become white matter.
🗑
|
||||
| Q: Where is the marginal zone in relationship to the mantle zone? | A: The marginal zone is peripheral to the mantle zone in location.
🗑
|
||||
| Q: White matter is made up of _______, while gray matter is mostly _______. | A: Nerve fibers (axons), cellular.
🗑
|
||||
| Q: Are basal plates ventral or dorsal? | A: Ventral.
🗑
|
||||
| Q: Are basal plates motor or sensory? | A: Motor.
🗑
|
||||
| Q: Are alar plates ventral or dorsal? | A: Dorsal.
🗑
|
||||
| Q: Are alar plates motor or sensory? | A: Sensory.
🗑
|
||||
| Q: What separates basal plates from alar plates? | A: The sulcus limitans.
🗑
|
||||
| Q: This structure contains the centers to regulate respiration, heartbeat, and reflex movements. | A: The medulla oblongata.
🗑
|
||||
| Q: The medulla oblongata is associated with which cranial nerves. | A: CN’s VIII, IX, X, XI, and XII.
🗑
|
||||
| Q: This relay center between the spinal cord and higher centers contains CN nuclei. | A: The medulla oblongata.
🗑
|
||||
| Q: What gives rise to the inferior olivary nuclear complex? | A: Alar plates.
🗑
|
||||
| Q: The alar plates of this structure give rise to rhombic lips which fuse to form the cerebellum. | A: The pons.
🗑
|
||||
| Q: True or false? The pons has massive gray matter tracts from the marginal layer. | A: False! To make this a true statement you would have to substitute white matter for gray matter.
🗑
|
||||
| Q: The alar plates give rise to the inferior olivary nuclear complex in the medulla oblongata. What do they give rise to in the pons? | A: The pontine nuclei.
🗑
|
||||
| Q: The pons is associated with which cranial nerves? | A: CN’s V, VI, VII, and part of VIII.
🗑
|
||||
| Q: Cerebral peduncles are closely associated with which structure? | A: The midbrain.
🗑
|
||||
| Q: Alar plates give rise to the superior and inferior colliculi. These make up the tectum, also known as _______. | A: The corpora quadrigemina.
🗑
|
||||
| Q: Where do the red nuclei and substantia nigra arise from? | A: Basal plates.
🗑
|
||||
| Q: The midbrain is associated with which cranial nerve? | A: CN’s III & IV.
🗑
|
||||
| Q: Since cells that make up the substantia nigra contain dopamine & melanin, which disease would start here? | A: Parkinson’s.
🗑
|
||||
| Q: Brain stem CN nuclei are organized into 7 columns: What are they? (think systemic anatomy) | A: GSE, SVE, GVE, GVA, GSA, SVA, and SSA.
🗑
|
||||
| Q: Name the parts of the basal nuclei. | A: The basal nuclei are made up of the caudate nucleus and the lenticular nucleus. [The lenticular nucleus is made up of the putamen & globus pallidus.]
🗑
|
||||
| Q: The lenticular nucleus can be further broken down into the _______ and _______. | A: The putamen & globus pallidus.
🗑
|
||||
| Q: Give another name for the lenticular nucleus. | A: The lentiform nucleus.
🗑
|
||||
| Q: Where would you find the corpus striatum? | A: On the floor of the telencephalon.
🗑
|
||||
| Q: How many basal plates are found in the diencephalon? | A: None! There aren’t any in the telencephalon either.
🗑
|
||||
| Q: I say diencephalon, you think… | A: Thalamus (or thalamic structures).
🗑
|
||||
| Q: The pineal gland is also known as the _______. | A: The epithalamus which is a dorsal swelling of the diencephalon.
🗑
|
||||
| Q: The dorsal part of the diencephalon is the ______. | A: Thalamus.
🗑
|
||||
| Q: The ventral part of the diencephalon is the _______. | A: Hypothalamus.
🗑
|
||||
| Q: This structure is a ventral outpouching of the diencephalon. | A: The infundibulum.
🗑
|
||||
| Q: Human eyes are actually outpocketings of the _______. | A: Diencephalon.
🗑
|
||||
| Q: What is the derivation of the cranial nerve nuclei? | A: Motor nuclei arise from brain stem basal plates, sensory relay nuclei arise from brain stem alar plates.
