CHAPTER 9: Diencephalon

The thalamic sensory relay neurons include the:

A. thalamic reticular nuclei.

B. association nuclear group.

C. pulvinar.

D. lateral geniculate nucleus.

D. lateral geniculate nucleus.

Somatic sensory information from the contralateral body innervates third-order cells in the:

A. ventroposterolateral nucleus (VPL) of the thalamus.

B. ventroposteromedial nucleus (VPM) of the thalamus.

C. medial geniculate nucleus of the thalamus.

D. dorsomedial nucleus (DM) of the thalamus.

A. ventroposterolateral nucleus (VPL) of the thalamus.

Within the Papez circuit, a lesion of the anterior nuclear group will most likely produce loss of the following:

A. Ability to control eye motions

B. Emotion and factual memories

C. Episodic memory and spatial orientation

D. Motor control of gait and balance

C. Episodic memory and spatial orientation

Thalamic dorsomedial nucleus projections bypass the primary somatosensory cortex, with the following consequence:

A. Pain processing is more precise and detailed than for VPL and VPM.

B. Pain processing is less precise and detailed than for VPL and VPM.

C. Pain processing incorporates the reticular formation for nonspecific arousal.

D. Pain processing is centralized within the temporal association area.

B. Pain processing is less precise and detailed than for VPL and VPM.

These structures regulate water metabolism through secretion of vasopressin.

A. Paraventricular and supraoptic hypothalamic nuclei

B. Solitary and parabrachial nuclei

C. Ventral anterior and ventral lateral nuclei

D. Reticular and intralaminar nuclei

A. Paraventricular and supraoptic hypothalamic nuclei

Release of this by the arcuate nucleus stimulates mitosis and is important in adults for tissue maintenance and metabolism.

A. Somatostatin

B. Growth hormone–releasing hormone

C. Oxytocin
