|
Is alobar holoprosencephaly the worst form? |
Yes |
|
|
Holoprosencephaly represents a spectrum of malformations: (3) |
-alobar (most severe form) -semilobar -lobar |
|
|
This condition is characterized by grossly abnormal brain in which there is a common large central ventricle. |
Disorders of diverticulitis and cleavage |
|
|
Abnormalities found in holoprosencephaly include: (5) |
Cyclopia, cebocephaly, ethmocephaly, median cleft, and holotelencephaly |
|
|
Congenital anomaly involving the disruption in development of the cerebellar vermis and roof of the fourth ventricle |
Dandy-Walker Malformation |
|
|

Agenesis of the corpus callosum is highly associated with... |
Dandy-Walker Malformation |
|
|

Chiari ll |
|
|
Is the most important cause of abnormal neurodevelopment sequelae in a premature infant. |
Periventricular leukomalacia |
|
|
What is 1 major type of neonatal hypoxic-ischemic brain injury? |
Periventricular leukomalacia or white matter necrosis |
|
|
-These are most commonly the result of the sequelae of germinal matrix hemorrhage in premature infants. - these present as discreet cysts in the lining of the ventricles, and are seen as a smooth-walled spherical cyst in the lateral ventricle at the caudothalamic grove where there was a clot previously. |

|
The central cerebellar white matter is referred to as the "arbor vitae" or tree-of-life due to? |
Its appearance and function of bringing motor and sensory information to and from the cerebellum |
|
|
The cerebellum lies... |
In the posterior cranial fossa under the tentorium cerebelli. |

|
The two hemispheres are connected by... |
The vermis |
|
|
What two structures is part of the brainstem and hindbrain? |
Pons and medulla oblongata |
|
|
Is the part of the brain connecting the forebrain ( cerebral hemispheres, thalamus, and hypothalamus) and the spinal cord |
