To Do Before Lab!
• Read over the Lab 2 Anatomy of the Nervous System Lab Slides
To Do After Lab!
• Keep all the notes and diagrams you create as part of the activities below. Lab practical exams will be composed of a selection of
these questions/tasks.
Today’s Materials
• Brain models
• Sheep brains
*Be able to identify the structures listed in the Brain Table and indicate a function. The complete list of identifiable structures also appears
in boldface in the following activities.
To receive full credit for this lab, have your instructor check off the following at the completion of each activity.
All colored tape labels are returned to their original co ndition.
All dissecting pins are returned to their original location. Appropriate PPE (gloves and eyewear).
Completion of all model and sheep brain labeling.
Activity 1: External Anatomy of the Human Brain
1. Obtain a brain model. As a group, use the colored tape labels provided to identify the following external brain
structures or anatomical landmarks along the following views: dorsal, lateral, and ventral. Once complete, take a
photo of your work to review/study and remember to remove all tape!
Dorsal or Lateral View
• Longitudinal fissure
• Transverse cerebral fissure
• Central sulcus
• Precentral gyrus
• Postcentral gyrus
• Cerebellum
Dorsal or Lateral View
• Lateral sulcus
• Parietal lobe
• Frontal lobe
• Temporal lobe
• Occipital lobe
Ventral View
• Pituitary gland (hypophysis)
• Pons of brain stem
• Medulla oblongata of brain stem
Activity 2: External Anatomy of the Sheep Brain
1. Obtain a sheep brain. As a group, use the dissecting pins provided to identify the following external brain structures
or anatomical landmarks along the following views: dorsal and lateral. Once complete, take a photo of your work to
review/study and remember to remove all pins!
Dorsal or Lateral View
• Pia mater
• Dura mater
• Arachnoid mater
• Spinal cord
• Longitudinal fissure
• Transverse cerebral fissure
• Cerebellum
• Lateral sulcus
• Brain stem models
•
Spinal nerve models
