Brainstem & cranial nerves
Product code: HP1204
-
Whole Whole region / system / unpaired organ.
The brainstem interconnects the cerebrum, cerebellum, and spinal cord, via numerous tracts. It also contains multiple groups of nuclei associated with cardiac, respiratory, parasympathetic, and motor functions, consciousness, and most functions of the cranial nerves. This Silicone Plastinate reveals the structure, relations and various connections and tracts of the brainstem. The origin of most cranial nerves is revealed, alongside the fourth ventricle.

Key features include
- Brainstem with the diencephalon, part of the ventricular system, and the proximal spinal cord, with the arachnoid and blood vessels removed.
- External features of the brainstem including its three main parts (midbrain, pons, medulla oblongata), cerebral peduncles, interpeduncular fossa, and pyramids of the medulla oblongata.
- Cerebellum removed to reveal the cerebellar peduncles, fourth ventricle, superior colliculus, inferior colliculus, pineal gland, and cuneate and gracile tubercles and fasciculi.
- Origin and proximal parts of the cranial nerves (most), including the posterior brainstem origin of the trochlear nerve (CN IV).
- Optic chiasm and its relationship with the pituitary gland.
- Olfactory bulb and tract.
- Most of the cerebrum is removed to the level of the diencephalon.
- Posterior and superior view into the lateral ventricles, revealing the septum pellucidum and interventricular foramen.
- Part of the septum pellucidum and one fornix removed to reveal a superior view into the third ventricle.
- Anatomical relations of the lateral ventricle including parts of the caudate nucleus, hippocampus, thalamus, and fornix.
- Choroid plexus within the lateral and fourth ventricles.
