Thalamus and Internal Capsule (Task 2)

Question 1

Problems with these structures can impact the thalamus as they are adjacent

Answer 1

Third ventricles

Question 2

Every sensory system has a thalamic nucleus apart from:

Answer 2

Olfactory System

Question 3

Key functions of thalamic nuclei

Answer 3

Relaying limbic, sensory and motor info to cerebral cortex

Regulating consciousness, sleep and alertness

Question 4

Components of diencephalon

Answer 4

Thalamus
Hypothalamus
Subthalamus

Question 5

Role of ventral posterolateral thalamic nuclei (VPL)

Answer 5

Medial lemniscal and spinothalamic pathways project their fibers onto VPL

VPL projects onto primary and secondary somatosensory cortex

Question 6

Role of medial geniculate nucleus

Answer 6

Thalamic relay station of the auditory pathway

Receives inputs from other auditory nuclei

Projects fibers via the acoustic radiation to auditory centers of the temporal cortex.

Question 7

Lateral geniculate nucleus

Answer 7

Thalamic relay station of the visual pathway
