Brain Dissection
Orientation of the Brain
Label the Following Aspects of the Brain:•Anterior•Posterior•Lateral •Medial
Orientation ContinuedLabel the Following Aspects of the Brain:•Anterior•Posterior•Dorsal •Ventral
Planes of Orientation
Draw the following Cross Sections:• Frontal or Coronal• Saggital
Planes of OrientationDraw the following Cross Sections:• Frontal or Coronal• Transverse
Meninges: the protective coverings• dura mater: tough outer covering (may have been mostly
removed)• arachnoid layer and pia mater likely still cover brain
The Gyri and Sulci• Remove the arachnoid layer and blood vessels
carefully by using tweezers.• This should make the gyri and sulci very visible
Gyrus
Sulcus
The Brain Stemaka medulla oblongata
This area is made up of the:• Pons• Medulla
PonsMedulla
The Cerebellum
cerebellum
The Cerebrum
Label the Following:•Frontal Lobe•Parietal Lobe•Temporal Lobe•Occipital Lobe
Hint: they correspond with the bones of the skull
The Cerebrum Continued
Label the Following:• Temporal Lobe• Parietal Lobe
Observing the Internal Brain Anatomy
• Cut the brain in a saggital cross section using your scalpel
• Corpus Callosum• Thalamus• Hypothalamus• Pons• Medulla
