|
Brain stem is completely covered by what?
|
cerebellum and cerebrum except for the caudal part of the medulla
|
|
|
what does the cerebellum consists of?
|
a medially placed vermis and two laterally placed hemispheres
called cerebeller vermis and cerebeller hemispheres |
|
|
what is the entire outer surface of the cerebellum consists of?
|
It consists of cerebellar cortex which is folded up into a series of narrow ridges called folia
|
|
|
cortex
|
the skin of the brain; outer layer
|
|
|
Cerebrum is divided into left and right halves called?
|
cerebral hemispheres and divided by the medial longitudinal fissure
|
|
|
cerebral cortex
|
outer surface of cerebrum folded into a series of ridges
|
|
|
ridges in cerebrum is called?
|
gyri
|
|
|
furrows that separate (between) the gyri is called?
|
sulci or fissures
|
|
|
Sulci
|
filled with many small blood vessels and with the pia and arachnoid membranes
|
|
|
If cerebral hemispheres are spread slightly and the blood vessels and pia are removed, what can be seen?
|
Heavy bands of white fibres connecting the hemispheres called corpus callosum
|
|
|
corpus callosum
|
Heavy bands of white fibres connecting the hemispheres
|
|
|
What are the four mounds that are exposed after we pick out the pia and blood vessels?
|
The superior and inferior colliculi
|
|
|
The superior and inferior colliculi
|
The superior colliculi are much larger and better developed than the inferior colliculi.
|
|
|
depths of the sulci can be seen if we pulled out the small blood vessels
|
.
|
|
|
White matter
|
White matter owes its color to the presence of large numbers of myelinated nerve fibres
|
|
|
myelinated
|
a white tissue forming an insulating sheath ( myelin sheath ) around certain nerve fibres.
|
|
|
sheath
|
a case or covering like a condom
|
|
|
grey matter
|
grey matter consists of nerve cell bodies and fine unmyelinated fibres
|
|
|
Cranial nerves
|
trigeminal nerve and optic nerve
|
|
|
Fissures and sulci of the cerebral cortex are quite variable from one species of animal to another
|
.
|
|
|
What fissure is present in nearly all mammals?
|
the rhinal fissure
|
|
|
the rhinal fissure
|
the rhinal fissure is the dividing line between the pyriform lobe, located ventrally, and the neocortex which is the prominent furrowed type of cerebral cortex visible in dorso-lateral views of the brain
|
|
|
Cerebral cortex as a whole includes the hippocampal formation and the medial strip of cortex lying immediately dorsal to the corpus callosum
|
.
|
|
|
Subdivisions of the cerebral cortex are developed to different degrees in different kinds of animals
|
ex. something resembling the pyriform lobe can be reconized in various kinds of amphibia and such but none of these animals has a tissue that closely resembles the neocortex
|
|
|
Animals that have neocortex
|
Suggests that some of the differences in behavior between mammals and other animals may depend on the presence of the neocortex
