caption_attribution_description: Human brainstem and thalamus - posterior view Taenia choroidea (and lateral: Lamina affixa, Stria terminalis) Thalamus, Pulvinar thalami (Ventriculus tertius) Stalk of Glandula pinealis Habenula Stria medullaris Colliculus superior Brachium colliculi superioris Colliculus inferior Brachium colliculi inferioris Corpus geniculatum mediale Sulcus medianus Pedunculus cerebellaris superior Pedunculus cerebellaris inferior Pedunculus cerebellaris medius Tuberculum anterius thalami Obex, Area postrema A: Thalamus, B: Mesencephalon, C: Pons, D: Medulla oblongata On this specimen, the following thalamic structures can be seen: 1. the Epithalamus (Stria Medullaris Thalami, Habenula, &amp; Pineal), 2. the Anterior Nucleus of the dorsal thalamus (Anterior Tubercle) and, 3. the Pulvinar (the large posterior portion of the dorsal thalamus which overhangs the midbrain. The Medulla, Pons &amp; Midbrain are delineated on the posterior surface of the brainstem. NOTE: The 4 Colliculi of the tectum are refered to collectively as the Quadrigeminal Plate. The three Cerebellar Peduncles are shown here as they enter the brainstem on each side. In the Midbrain identify the Superior Colliculus and Inferior Colliculus. Also identify the Brachium of the Superior Colliculus and the Brachium of the Inferior Colliculus which connect with the Lateral Geniculate Body and Medial Geniculate Body, respectively. The cerebellum forms the roof of the 4th ventricle and is connected to the brainstem by 3 pairs of peduncles or pillars (shown on right side of brainstem) . The peduncles are made up of axons entering and leaving the cerebellum. The Inferior Cerebellar peduncle projects from the medulla, the large Middle Cerebellar Peduncle projects from the Pons, and the Superior Cerebellar Peduncle connects with the midbrain.

context_page_description: Lamina affixa is a layer of epithelium growing on the surface of the thalamus and forming the floor of the central part of lateral ventricle, on whose medial margin is attached the choroid plexus of the lateral ventricle; it covers the superior thalamostriate vein and the superior choroid vein. The torn edge of this plexus is called the tela choroidea.
  On the surface of the terminal vein is a narrow white band, named the lamina affixa.
  GDF-15/MIC-1 has been observed in lamina affixa cells.
