Diencephalon is part of the Neuroanatomy section of Anatomy. Practise 13 exam-style MCQs for NEET PG, FMGE, INI-CET and NEET SS, each with the correct answer and a detailed explanation.
Diencephalon MCQs centre on the hypothalamus as visceral and endocrine control centre, the epithalamus and pineal development, and collicular reflexes for vision and hearing — high-yield NEET PG revision.
The hypothalamus of the diencephalon is the control center for visceral and endocrine functions. Reference - Textbook of Langman's, 12th Edition, Central Nervous System Embryology Page number - 287
The colliculi serve as relays for auditory and visual reflexes and arise from the mesencephalon. The medulla is derived from myelencephalon. The diencephalon contains the thalamus, a sensory relay station. The cerebellum arises from metencephalon.

The pineal gland develops from the diencephalon. Hence, defect in its development can cause pineal agenesis. The most caudal part of the roof plate of the diencephalon develops into the pineal gland. It is also known as the pineal body or epiphysis cerebri. The pineal body initially appears as an epithelial thickening in the midline. It begins to evaginate by the 7th week and becomes a solid organ. Reference - Textbook of Langman's, 12th Edition, Central Nervous System Embryology Page number - 297
The superior colliculi of the mesencephalon serve as reflex centers for visual input. Reference - Textbook of Langman's, 12th Edition, Central Nervous System Embryology Page number - 287
Tuber cinereum is not a part of the epithalamus. It is a part of the hypothalamus. The epithalamus consists of: Anterior and posterior paraventricular nuclei Medial and lateral habenular nuclei Stria medullaris thalami Posterior commissure Pineal gland Reference : Textbook of Gray's Anatomy for students, 3rd Edition, Head and neck, Page number - 871
The hypothalamus, a crucial part of the brain, receives its blood supply from the perforating arteries associated with the Circle of Willis. If there is an occlusion or blockage in these arteries, it can lead to insufficient blood flow, causing an infarct (tissue damage) in the hypothalamus. This can result in various neurological and endocrine disturbances, affecting vital functions regulated by the hypothalamus, such as temperature regulation, hormone secretion, and control of appetite and sleep.
