Answer:
The correct answer is- diencephalon
Step-by-step explanation:
Diencephalon is a segment of brains that lies cerebral cortex and brain stem. It includes thalamus, hypothalamus, and epithalamus. Diencephalon provides an important link between the endocrine and nervous systems.
The primary function of the diencephalon is to relay the sensory signals in the cerebral cortex region of the brain and regulate the function of the autonomic nervous system. It works with the other parts of the body and affects different functions like autonomic function, endocrine function, sensory function, managing emotions, etc.
So diencephalon includes thalamus, hypothalamus, and epithalamus.
