Diencephalon Flashcards
What does the Diencephalon include?
- Dorsal Thalamus
- Hypothalamus
- Ventral Thalamus
- Epithalamus
Where is the Dorsal Thalamus located? In relation to other structures.
- Superior to the hypothalamic sulcus
- Between the interventricular foramen and splenium of the corpus callosum.
What are the relevant EXTERNAL structures in the Dorsal Thalamus?
- Lateral Geniculate Body
- Medial Geniculate Body
- Pulvinar
What are the relevant INTERNAL structures in the Dorsal Thalamus?
- Sensory
- Motor
- Modulatory
What is the function of the Dorsal Thalamus?
Processes most of the information that reaches the cerebral cortex.
Where is the Hypothalamus located? In relation to other structures.
- Inferior to the hypothalamic sulcus
- superior to the pituitary gland
- caudal to the lamina terminalis
What are the relevant EXTERNAL structures in the Hypothalamus?
- Infundibulum
- Mammillary Bodies
What are the relevant INTERNAL structures in the Hypothalamus?
- Suprachiasmatic Nucleus
What is the function of the hypothalamus?
Integrates autonomic response and endocrine function with behavior. Control of homeostasis, reproduction, and emergency response to stress.
Where is the Ventral Thalamus located? In relation to other structures.
- Caudal to the hypothalamus
- Rostral to the diencephalon-brainstem junction
- Lateral to the midline
What is the function of the Ventral Thalamus?
Related to the basal ganglia of the telencephalon.
Where is the Epithalamus located? In relation to other structures.
In close approximation to the posterior commissure?
What are the relevant external structure of the Epithalamus?
Pineal Gland
What is the function of the Epithalamus?
Related to the limbic system, role in circadian rhythm.
