Question

Which of the following is/are true of the epithalamus?

1) Creates the lateral ventricles
2) Contains the mammillary body
3) Forms the roof of the diencephalon
4) Processes sensory information and relays it to the cerebrum

Answer 1

The true statement about the epithalamus is that it forms the roof of the diencephalon, but it does not create the lateral ventricles, contain the mammillary body, nor process sensory information for the cerebrum.

Step-by-step explanation:

Regarding the question about the epithalamus, the following statement is true: the epithalamus forms the roof of the diencephalon. The epithalamus is part of the diencephalon, which is composed primarily of the thalamus and hypothalamus. These structures define the walls of the third ventricle. The epithalamus contains the pineal gland, which plays a role in the regulation of sleep-wake cycles but is not responsible for creating the lateral ventricles, does not contain the mammillary body, and does not process sensory information to relay to the cerebrum. Sensory information processing and relaying is a function of the thalamus, not the epithalamus.
