Thalamus, epithalamus, hypothalamus....
diencephalon
There are two structures that make up the Diencephalon. The main structure of the diencephalon is hypothalamus thalamus and the second is the subthalamus.
Its the Hypothalamus
Diencephalon
The diencephalon includes structures such as the thalamus, hypothalamus, epithalamus, and subthalamus. However, the cerebellum is not part of the diencephalon; it is a separate structure located posterior to the brainstem and is primarily involved in motor control and coordination. Other regions like the cerebrum and brainstem are also not part of the diencephalon.
The Hypothalamus.
Pineal Gland
i think it is thalamus
The thalamus is part of the limbic system (or more specifically, it is the largest structure in the diencephalon).
The two optic nerves reach the diencephalon at the optic chiasm, a structure located at the base of the brain where the nerves partially cross over each other. From the optic chiasm, the optic nerves continue on to the thalamus within the diencephalon.
The pineal gland is a cone-shaped structure attached to the upper posterior portion of the diencephalon. It secretes melatonin, a hormone that regulates sleep-wake cycles and circadian rhythms in the body.
