Diencephalon Flashcards
(28 cards)
Four main compartments of the diencephalon
Thalamus, epithalamus, hypothalamus and subthalamus
Motor control areas that synapse in the thalamus
Basal ganglia and cerebellum
Main role of the thalamus
Sensory relay for information that needs to reach the cortex
Nine main nuclei of the thalamus
Anterior nuclear group Mediodorsal nucleus Pulvinar Medial Geniculate body Lateral Geniculate body Ventroposteromedial nucleus Ventroposterolateral nucleus Ventral anterior nucleus Ventral lateral nucleus
Which nuclei in the thalamus is associated with the Papez circuit?
Anterior nuclear group
Which nuclei in the thalamus is associated with memory?
Mediodorsal nucleus
Which nuclei in the thalamus is associated with somesthetic, visual and auditory input?
Pulvinar nucleus
Which nuclei in the thalamus is associated with the first degree auditory cortex?
Medial Geniculate body
Which nuclei in the thalamus is associated with the firt visual cortex?
Lateral Geniculate body
Which 2 nuclei in the thalamus is associated with sensory input
Ventroposteromedial and lateral nuclei
Which nuclei in the thalamus is associated with sensory input from body and limbs?
Ventroposterolateral nucleus
Which nuclei in the thalamus is associated with sensory input from the face and tase
Ventroposteromedial nucleus
Which 2 nuclei in the thalamus is associated with motor input from basal ganglia and cerebellum?
Ventral anterior and ventral lateral nucleus
Additional functions of the thalamus
Concerned with sensations like pain and temp
control of emotional behavior and recent memory
Autonomic control of viscera
Personality and intellect of an individual
Functions of the hypothalamus
Helps maintain homeostasis
Role in autonomic, endocrine and limbic systems
Involved in feeding responses
Name the 10 nuclei of the hypothalamus
Paraventricular nucleus Dorsomedial nucleus Posterior hypothalamus Mammillary body Ventromedial nucleus Arcuate nucleus Supraoptic nucleus Suprachiasmatic nucleus Anterior hypothalamus Preoptic nucleus

Arcuate nucleus
Which nuclei in the hypothalamus is associated with circadian rhythms?
Suprachiasmatic
Which nuclei in the hypothalamus is associated with sensing elevation in body temperature?
Anterior hypothalamus
