Thalamus is the biggest relay station in the CNS
yes
no
The reticular thalamic nuclei form a shell-like structure on the antero-lateral surface of the thalamus
a basic function of the thalamus is processing of sensory information
hypothalamus is concerned with control of food and water intake
subthalamus is somatosensory control center
mamillary bodies are anatomically related to the hypothalamus
diencephalon originates from the prosencephalic ventricle
lateral thalamic nuclei are classified functionally as associate nuclei
the anterior group of thalamic nuclei are functionally part of the limbic system
internal medullary lamina divides the thalamus into 3 groups of nucei- anterior, medial and lateral
which of the following thalamic nuclei has a motor function
lateral dorsal nucleus
mediodorsal nucleus
ventral lateral nucleus
ventral posterior nucleus
lateral posterior nucleus
spinothalamic fibers project to which one of the following thalamic nuclei
ventral posteromedial (VPM) nucleus
pulvinar
ventral anterior nucleus
ventral posterolateral (VPL) nucleus
anterior nucleus
cerebellar fibers project to which one of the following thalamic nuclei
the globus pallidus projects to which one set of thalamic nuclei
centromedian, ventral anterior, and ventral lateral nuclei
ventral anterior, ventral lateral, and anterior nuclei
ventral lateral, lateral dorsal, and lateral posterior nuclei
mediodorsal, ventral posterolateral (VPL), and ventral posteromedial (VPM) nuclei
centromedian, lateral dorsal, and lateral ventral nuclei
the thalamus receives precortical sensory input from all of the following modalities EXCEPT
general somatic sense
gustation
vision
audition
olfaction
all of the following statements concerning the mediodorsal nucleus are correct EXCEPT it
receives input from the amygdaloid nucleus
receives input from the intralaminar muscle
is part of the limbic system
is part of the extrapyramidal motor system
has reciprocal connections with the prefrontal cortex
which of the following structures is a part of the hypothalamus
corpus pineale
corpus geniculatum laterale
infundibulum
inferior colliculi
which of the thalamus is not true
the medial group of nuclei receives afferents from hypothalamus
the ventral anterior nucleus is a part of the extrapyramidal neural network
the ventral anterior nucleus doesn't receive afferents from pallidum and substantia nigra
the ventral posterior lateral nucleus receives afferents from spinal lemnisucs
the ventral posterior medial nucleus receives afferents from trigeminal lemniscus
which of the following structures is a part of epithalamus
hypophysis
corpus geniculatum mediale
habenular trigone
superior colliculus
it has laterally the posterior limb of internal capsule.
the hypothalamic sulcus (sulcus of Monro), which extends from the interventricular foramen to the cerebral aqueduct is the boudnary between the thalamus and midbrain (mesencephalon)
its upper surface is covered by a layer of white substance, named the stratum zonale
the stria terminalis cover the thalamostriate vein, marking a line of separation between the thalamus and the caudate nucleus
which of the listed structures belongs to epithalamus
optic chiasm
hypophisis
lamina affixa
pineal body
mammilary bodies
the hypothalamus
is a division of the diencephalon
is perfused by the posterior communicating artery
is visible only from the ventral aspect of the brain
lies within the walls of the fourth ventricle
includes the mamillary body
the third ventricle
communicates with the lateral ventricles through the interventricular foramina
communicates with the fourth ventricle by means of the cerebral (Sylvian) aqueduct
communicates with the subarachnoid space through holes in its roof
has no choroid plexus
is anterior to the pineal body
the thalamus
receives the terminations of the second neurons of the proprioceptive pathway mainly from the same side of the body
receives fibers from the mamillary bodies
contains the cell bodies of the third neuron of the touch pathway
has connections with the motor areas of the cerebral cortex
receives fibres from the dentate nucleus of the cerebellum mainly from the same side
is separated from the lentiform nucleus by anterior limb of the internal capsule
forms part of the lateral wall of the third ventricle
has the interventricular foramen posterior to it
is inferior to the body of the fornix
has an upper surface which is partly in the floor of the lateral ventricle
in connection with thalamus
the anterior group of nuclei is connected to structures of limbic system
the lateral group of nuclei are responsible for the behavioural actions
the ventral posterior lateral nucleus receives afferents from spinal cord
the ventral posterior lateral nucleus sends fibers to spinal cord
the lateral geniculate body is connected to the visual system
the subthalamus
is located between the midbrain tegmentum and diencephalon
the subthalamic nucleus belongs to the pyramid system
the subthalamic nucleus has a biconvex shape
abuts the external capsule laterally
is concerned with motor control
controls the body homeostasis
forms the wall of the third ventricle
is seen on the ventral surface of the brain
receives direct impulses from the retina
is subdivided into three nuclear groups
is anatomically associated with chiasma opticum
is bounded laterally by tractus opticus
secretes hormones
is the control center for many autonomic functions
is connected with the endocrine and nervous systems
controls circadian rhythms
forms the ventral part of diencephalon
governs emotional behaviour
has projections to the spinal cord
metathalamus
is a visual and auditory relay station
is connected with the colliculi of the midbrain tectum
is closely related to the thalamus
controls somatomotor activity
is concerned with emotional behaviour
