L8 - forebrain Flashcards
origin or forebrain
prosencephalon
contents of forebrain
inner and outer
contents of inner brain
diencephalon
contents of outer brain
telencephalon
contents of diencephalon
thalamus
hypothalamus
contents of telencephalon
- cerebral cortex and CN1
- corpus striatum
- limbic structures
- subcortical fibres
- cerebral hemisphers
role of forebrain
responsible for a higher level processing such as memory, cognition, learning, integration…etc
what is the telencephalon
two swellings on either side of the midline connected via the lamina terminalis
development of the diencephalon
swellings of the lateral aspect of the central canal, the lumen of the central canal is diminished , forming the diencephalon
location of thalamus on the diencephalon
dorsally
location of hypothalamus on the diencephalon
ventrally
which ventricle lies in the middle of the diencephalon
3rd
location of inferior horn of lateral ventricle
temporal lobe
location of anterior horn of lateral ventricle
frontal lobe
location of posterior horn of lateral ventricle
occipital lobe
role of thalamus
relay station between parts of CNS
role of hypothalamus
autonomic and neuroendocrine functions
role of subthalamus
functionally part of basal nuclei - involved in motor control
role of epithalamus
includes pineal gland - secretes melatonin
basal nuclei
cell bodies in the cns
what is the thalamus composed of
grey matter
how are the thalami connected
interthalamic adhesion / mass intermedia
motor processing of thalamus
through connections with basal ganglia and cerebellum
nuclei and internal organisation of thalami
anterior nuclear group
medial nuclear group
lateral nuclear group
lateral nuclear group of the thalami
ventral posterior lateral
ventral posterior medial
lateral geniculate
medial geniculate
role of ventral posterior lateral
receives information from somatic sensory system and send information to primary sensory cortex
