Brain Models

In the lab we have many different brain models. You should be familiar with all of them.

Start by locating the following:
  1. cerebrum (cerebral hemispheres)
    • frontal lobes
    • parietal lobes
    • temporal lobes 
    • occipital lobes
  2. cerebellum
  3. pons
  4. medulla oblongata
  5. convolutions (gyri, sulci, fissures)
    • longitudinal fissure
    • transverse fissure
    • lateral sulcus
    • central sulcus
    • precentral gyri
    • postcentral gyri






On the models and in the pictures below, locate the following:

  • cerebellum
  • arbor vitae
  • pons
  • medulla oblongata
  • thalamus
  • hypothalamus
  • epithalamus
  • optic chiasma
  • pituitary gland
  • pineal gland
  • corpus callosum
  • fornix
  • septum pellucidum (visible only on most models)
  • lateral ventricle (visible only on a couple of models)
  • corpora quadrigemina
  • superior colliculi
  • inferior colliculi
  • cerebral peduncles
  • cerebellar peduncles
  • cerebral aqueduct
  • third ventricle
  • fourth ventricle
  • cerebral aqueduct
  • choroid plexus
  • falx cerebri (visible only on some models)
  • superior sagittal sinus (visible only on some models)
  • inferior sagittal sinus (visible only on some models)














Below are two photos of the pons, medulla oblongata, and associated structures. In these pictures locate:
  • pons
  • medulla oblongata
  • thalamus
  • optic chiasma
  • corpora quadrigemina
  • superior colliculi
  • inferior colliculi
  • cerebral peduncles
  • cerebellar peduncles
  • pyramids



On the model of the fetal skull look for the sinuses:
  • superior sagittal sinus
  • inferior sagittal sinus
  • straight sinus
  • transverse or horizontal sinus
  • sigmoid sinus
  • internal jugular vein



Here is a picture of the model of the falx cerebri and associated with it straight, superior and inferior sagittal sinuses:

Below there are four pictures of the model of brain ventricles. In the pictures, try to locate the following:
  1. lateral ventricles
    • posterior horns
    • anterior horns
    • inferior horns
  2. third ventricle
  3. fourth ventricle
    • lateral apertures
    • median aperture
  4. cerebral aqueduct
  5. choroid plexus
