66. THE DIENCEPHALON. III VENTRICLE Flashcards
What is the diencephalon?
The diencephalon refers to the part of the brain located between the cerebral hemispheres and the brainstem. These include structures like the thalamus, hypothalamus, epithalamus, and the subthalamus.
Where is the third ventricle located?
The third ventricle is located in the center of the diencephalon, bounded by the structures of the diencephalon.
What is the third ventricle?
The third ventricle is a narrow tube that runs between the two thalamic bodies and the hypothalamus. It is responsible for CSF passage and contains a site where the choroid plexus releases CSF.
What connects the third ventricle to the lateral ventricles?
The third ventricle is in communication with the lateral ventricles through the interventricular foramen.
What connects the third ventricle to the fourth ventricle?
The third ventricle is in communication with the fourth ventricle through the cerebral aqueduct.
What is the thalamus?
The thalamus is the biggest structure in the diencephalon and acts as a relay point between sensory and motor information and the cerebral cortex.
What does the thalamus do?
The thalamus relays information to be processed by the cerebral cortex.
Where is the hypothalamus located?
The hypothalamus is located below the thalamus.
What does the hypothalamus control?
The hypothalamus controls various autonomic functions, including hormone balance, body temperature, and the autonomic nervous system.
What is the main function of the third ventricle?
The third ventricle plays a significant role in the control of the flow of CSF through the brain to ensure appropriate pressure and exchange of nutrients.
What do the structures of the diencephalon help control?
The structures of the diencephalon help in the control of the body’s homeostasis, integration of the senses, and emotional reactions.
