Presentation Transcript

  1. Brain Dissection

  2. Orientation of the Brain • Label the Following Aspects of the Brain: • Anterior • Posterior • Lateral • Medial

  3. Orientation Continued • Label the Following Aspects of the Brain: • Anterior • Posterior • Dorsal • Ventral

  4. Planes of Orientation Draw the following Cross Sections: • Frontal or Coronal • Saggital

  5. Planes of Orientation Draw the following Cross Sections: • Frontal or Coronal • Transverse or Axial

  6. Meninges: the protective coverings • dura mater: tough outer covering (may have been mostly removed) • arachnoid layer and pia mater likely still cover brain Dura mater

  7. 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

  8. The Brain Stemaka medulla oblongatahttp://www.youtube.com/watch?v=VF5PyeMG8Lo&feature=related This area is made up of the: • Pons • Medulla Medulla Pons

  9. The Cerebellum cerebellum

  10. The Cerebrum • Label the Following: • Frontal Lobe • Parietal Lobe • Temporal Lobe • Occipital Lobe • Hint: they correspond with the bones of the skull

  11. The Cerebrum Continued Label the Following: • Temporal Lobe • Parietal Lobe

  12. Observing the Internal Brain Anatomy • Cut the brain in a saggital cross section using your scalpel

  13. Corpus Callosum http://www.youtube.com/watch?v=ClzaP8HN2wc • Thalamus • Hypothalamus • Pons • Medulla Corpus Callosum Thalamus Hypothalamus Medulla Pons

  14. Internal Anatomy of the Cerebellum • Arbor Vitae http://www.youtube.com/watch?v=v0hH-KPAr00
