Human Anatomical

Brain with Arterial Supply Model

Life Size

Sit on a base, made of high quality PVC, this human brain and arterial supply model provides correct understanding of the external features of the brain and its arterial supply as a whole, as well as the relations between their component portions.

External features of the brain

• Cerebral Hemisphere: On its dossolateral surface the central sulcus, lateral and parieto-occipital fissures, the frontal, parieta, temporal and occipital lobes are shown.  On its median and basal surfaces the corpus callosun (cutting surface), the parieto-occipital and calcarine fissures, the olfactory bulb and tract are shown.
• Brain Stem: On its dorsal aspect the thalamus, pulvinar corpora quadrigemina and the rhomboid fossa are shown; On its ventral side, the optic chiasma, mammilary bodies, crura pedunculi and pons etc, are depicted.
• Cerebellum: Special features of cerebellar hemispheres and vermis are marked.
   

The arterial supply of the brain:

• sources: 2 vertebral, 2 internal carotid arteries.
• Right and left vertebral arteries: passing forwards on the ventral surfaces of medulla oblongate, unite at lower boarder of pons to form the upparied basilar artery. At upper-border of pons, balilar artery after giving off apair of superior cerebellar arteries divides into posterior cerebral arteries.  Posterior cerebral connected with internal right and left carotid arteries by post communicating branches. The internal carotid gives off the middle and anterior cerebral arteries.
• Arteria supply of the cerebellum and cerebrum
  • The cerebellum supplied by 3 pairs of cerebral arteries.  Post inferior cerebellar arteries arising from vertebral arteries.  Anterior inferior cerebellar arteries originating from basilar artery at lower border of pons.  Superior cerebellar arteries arising from basilar artery at superior border of pons.  The cerebrum, supplied mainly by 3 pairs of cerebral arteries.
  • The posterior cerebral arteries, terminal branches of the basaliar artery.  The middle cerebral arteries to stem of lateral fissure, supplying main part of dorsal lateral surface of brain.  The anterior cerebral arteries are terminal branches of internal carotid arteries to medial surface of the cerebral hemipheres.  (The vessel passing along the groove between dorsal surface of thalamus and caudate nucleus is vein, vena terminalis).

This model is dissected into 8 parts in natural size.
