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
