Station 1. Meninges and ventricles

Ventricles

Interactive 1

On a mid-sagittal image, label the parts of ventricular systems highlighted in blue:

    • 3rd ventricle
    • 4th ventricle
    • cerebral aqueduct
    • lateral ventricle

(Tap to open; use your Apple Pencil to draw)

Station 2. Cerebrum, sucli, and gyri

Lobes of the cerebrum

interactive 3

Check your base knowledge of the functions of the cerebrum by filling in the blank cells. (Tap the right arrow for answers)

Sulci/fissures of the cerebrum

Interactive 4

Name the major sulcus on the medial surface separating the lobes. (Tap to open; use your Apple Pencil to draw)

Interactive 5

Identify the major sulci and gyri. The sulci are indicated by the dashed line, and major gyri/regions are indicated by the solid lines.
Use Figures 10-5 and 10-6 in Clinical Neuroanatomy, 29e, by Stephen G. Waxman, for help in identification. (Tap to open; use your Apple Pencil to draw.)

Helpful hint 


Use the sulci to map out the gyri of the cerebrum for identification.

Major gyri of cerebral lobes

What are each of these colored parts?

The coronal section is through the mid-thalamus and anterior portion of the midbrain and pons. Specimen from Neuroanatomy Collection, Washington State University College of Veterinary Medicine. (Tap the right arrow for labels)

Portions of the medial temporal lobe outlined in green and light blue is an area where degeneration of cortical tissue occurs during Alzheimer’s disease (which will be discussed in the limbic system lecture in FMS 512 using case examples and providing clinical contexts).

Axonal fiber bundles of the cerebrum

Interactive 14

Color and label the different vessels forming the circle of Willis.
 (Tap to open; use your Apple Pencil to draw)

Interactive 15

Color and label the frontal, parietal, temporal, and occipital lobes lobes on the medial and lateral surfaces of the cerebral hemispheres. Use Figures 10-5 and 10-6 in Clinical Neuroanatomy, 29e, by Stephen G. Waxman, for help in identification. (Tap to open; use your Apple Pencil to draw.)
