Anatomy- Dissectable Human Brain- Demonstration Model

This meticulously designed model is an excellent educational tool for teaching physiology and hygiene courses. It provides a clear, detailed representation of the external features of the brain and its arterial supply, aiding students in understanding the complex anatomy of the brain, its components, and their relationships. Ideal for both theoretical and practical demonstrations, this model offers a comprehensive view of the brain’s structure and circulatory system.

Key Features:

• External Features of the Brain:
  • Cerebral Hemisphere:
    • Dorsolateral surface displays the central sulcus, lateral and parieto-occipital fissures, and lobes (frontal, parietal, temporal, and occipital).
    • Median and basal surfaces feature the corpus callosum (cutting surface), parieto-occipital and calcarine fissures, olfactory bulb and tract.
  • Brain Stem:
    • Dorsal aspect shows the thalamus, pulvinar, corpora quadrigemina, and the rhomboid fossa.
    • Ventral side includes the optic chiasma, mammillary bodies, crura pedunculi, and pons.
  • Cerebellum:
    • Distinct features of the cerebellar hemispheres and vermis are clearly marked.
• Arterial Supply of the Brain:
  • Sources:
    • Supplied by 2 vertebral arteries and 2 internal carotid arteries.
  • Right and Left Vertebral Arteries:
    • Pass along the ventral surface of the medulla oblongata and unite to form the basilar artery at the lower border of the pons.
    • The basilar artery gives off the superior cerebellar arteries and divides into posterior cerebral arteries at the upper border of the pons.
    • Posterior cerebral arteries connect with the internal carotid arteries via post-communicating branches.
  • Cerebellar Arterial Supply:
    • Three pairs of cerebellar arteries supply the cerebellum:
      • Posterior inferior cerebellar arteries (from vertebral arteries)
      • Anterior inferior cerebellar arteries (from basilar artery)
      • Superior cerebellar arteries (from basilar artery)
  • Cerebral Arterial Supply:
    • Three pairs of cerebral arteries supply the cerebrum:
      • Posterior cerebral arteries (from basilar artery)
      • Middle cerebral arteries (from the lateral fissure)
      • Anterior cerebral arteries (from internal carotid arteries)

Construction:
The model is made of high-quality plastic and is designed for dissection. It consists of eight parts and can be easily assembled on a base, allowing students to explore the brain’s structure and arterial supply in great detail.

Dimensions: Natural size

Ideal For:
