Thalamus is the biggest relay station in the CNS
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

Spinothalamic fibers project to which one of the following thalamic nuclei?
Ventral posteromedial (VPM) nucleus
Pulvinar
Ventral anterior nucleus
Ventral posterolateral (VPM) nucleus
Anterior Nucleus
Cerebellar fibers project to which one of the following thalamic nuclei?
Anterior nucleus
The global pallidus projects to which one set of the 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 nuclei
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 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 doesnt receive afferents from pallidum and substantia nigra
The ventral posterior lateral nucleus receives afferents from spinal lemniscus.
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
Which of the thalamus is NOT true:
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 boundary between the thalamus and midbrain (mesencephalon)
Its upper surface is covered by a layer of white substance, named the stratum zonale.
The stria terminalis covers the thalamostriate vein, marking a line of seperation between the thalamus and the caudate nucleus.
Which of the listed structures belongs to epithalamus?
Optic Chiasm
Hypophisis
Lamina Affixa
Pineal body
Mammillary 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) aquaduct.
Communicates with the subarachoid 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 proproceptive pathway mainly from the same side of the body.
Receives fibres 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 denate nucleus of the cerebellum mainly from same side .
Is separated from the lentiform nucleus by the 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 behavioral 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 diencphalon.
The subthalamic nucleus belongs to the pyramid system
The subthamalamic nucleus has 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 concerned with motor control.
The hypothalamus
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 behavior
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 connected with emotional behaviour
