i think it is thalamus
hypothalmus
right atrium and right ventricle
choroid plexus
It forms the central canal of the spinal cord and protects the brain from trauma.

The left ventricle forms the apex of the heart.
Cavity of the neural tube, it is the origin of the ventricles of the brain. Expansion within cerebral hemispheres (lateral ventricles 1-2), diencephalon (third ventricle), and medulla oblongata (fourth ventricle) forms chambers (ventricles) which are lined with ependymal cells.
These are all part of the brain stem called the thalamus. The thalamus forms the floor of the third ventricle and along with the pons and the medulla oblongata forms the brain stem.
Right and left masses of the thalamus.
right atrium and right ventricle
The hypothalamus is a small mass below the thalamus and forms floor and part of the lateral walls of the third ventricle.
The diencephalon consists of thalamus, hypothalamus, and epithalamus.
In the embryo the walls of the diencephalon forms at neural tube that begins the process of the fore brain. In adults, the diencephalon is located towards the upper end of the brain stem.
The third ventricle
The Lateral Malleolus is part of the fibula.
The greater tuberosity of the humerus forms the lateral contour of the shoulder. The supraspinatus muscle attaches at the greater tuberosity.
The lateral malleolus of the fibula forms the lateral portion of the ankle mortis.
