On coronal images, identify as many structures as you can.
If you are stuck for things to look for, try the following: pituitary gland, infundibulum, optic chiasm, cavernous sinuses containing internal carotid arteries, and sphenoid sinus.
The pituitary (red dotted line) has an anterior (P) and posterior (*) parts, as well as the infundibulum (I), into which projects the infundibular recess (IR) of the third ventricle. Note how close to the pituitary is the optic chiasm (green dotted line), above which is the supraoptic recess of the third ventricle. The mammillary bodies are posterior (yellow dotted line) separated from the infundibulum by a very thin membrane forming the floor of the third ventricle (the site for third ventriculostomy).
The pituitary fossa is bounded anteriorly and usually inferiorly (depending on the degree of pneumatization, by the sphenoid sinus, and posteriorly by the clivus.
