Exam 2017 Flashcards
The smost striking difference between a rat and a sheep brain (expect for the difference in size) is?
Rat brain do not have cerebral gyri
In a Klüver-Barrera staining of a brain preparation the white matter fibers colour blue, and the RNA in cell bodies violet. One of the following structures will be differently stained in such a preparation than the other 3. Which one?
lateral geniculate nucleus
The fornix connects the hippocampus with one of the brain structures mentioned below. Which one?
mammillary bodies
What do pyramidal tract, optic radiation and internal capsule have in common?
All 3 are white matter fibers
The caudate nucleus constitutes the lateral wall and bottom of an important subpart of the brain. Which one?
Lateral Ventricle
A microscopic slide of a coronal section through the septum has been stained for myelin (blue stain). On the midline, going through the septal nuclei, a vertical blue discoloration is visible. What structure causes this discoloration?
Fornix
In which part of the human brain is the putamen located?
Frontal lobe
On the ventral side of the brain, the optic chiasm marks the rostral end point of a particular part of the brain. Which part?
Hypothalamus
Different parts of the brain are associated with specific parts of the ventricular system. To which part of the brain belongs the lateral ventricle?
Telencephalon
In a coronal section in the sheep brain through the colliculi several structures can be seen. Only one of the lists of structures below is correct. Which one?
Cerebral peduncles, Peri-acqueductal grey, Substantia nigra
The caudate nucleus, the putamen, and the nucleus accumbens are parts of one bigger structure. Which one?
The Basal Ganglia
The ventral side of the sheep brain contains a smooth piece of cortex, the uncus. In humans, it is located in the medial temporal lobe. There are 2 important structures hidden behind this piece of cortex. Which are they?
Amygdala and Ventral Hippocampus
In a coronal section in the sheep brain through the optic chiasm a number of structures can be seen. One of the lists below names structures that can NOT be seen. Which list?
Lateral geniculate nucleus (LGN), Third ventricle, Fornix
The cerebral ventricles are generally not visible from the outside of the brain. However, in the first meeting on sheep brains we have seen that one part of the ventricular system can be made visible from the external of the brain, provided that we look in between 2 structures. Which ventricle part is that?
Fourth Ventricle
Which anatomical part of the brains contains most of the motor and premotor areas?
Precentral Gyrus
