Diencephalon Flashcards
Location of Diencephalon
Third ventricle
Middle of cerebrum
Major Divisions of Brain
Prosencephalon
Mesencephalon
Rhombencephalon
Function of Hypothalamus
Neuroendocrine regulation
Function of Thalamus
Major sensory and motor relay system
Function of Epithalamus
Limbic System
All sensations pass through thalamus except
Olfaction
Functions include regulation of consciousness, sleep and alertness
Thalamus
Thalamic Nuclei
Sensory Projections Motor projections Association areas Limbic System Non-specific
Somatosensory sensations
Ventral Posterolateral (VPL)
Trigeminal nerve sensations
Ventral Posteromedial (VPM)
Three components of trigeminal nerve
Opthalmic
Maxillary
Mandibular
Responsible for vision
Lateral Geniculate Body
Responsible for auditory
Medial Geniculate Body
Cerebellum and Basal Ganglia
Ventral Lateral Nuclei
Cerebellum
Ventral Intermedial Nuclei
Basal Ganglia
Ventral Anterior Nuclei
