Pal worksheet: nervous system, brain, brainstem, cerebellum, wk8

Brain

1. Describe the relationship of white matter to grey matter in the brain – how does this differ from spinal cord?

2. What does white matter consist of, and what is its function - are there any differences between CNS and PNS in terms of this white matter?

3. What does grey matter consist of? Grey matter for the most part consist of the cell bodies of neurons, as well as interneurons and supporting cells –

4. Draw a diagram of the brain from the side: label important sulci and gyri – label the major lobes of the brain – on each lobe list at least two functions that are known to require that particular lobe – label primary motor cortex, primary somatosensory cortex, lateral fissure and central sulcus, primary visual cortex, primary auditory cortex

5. Create an illustration of the meninges of the brain, include any important spaces and traversing structures – make sure the drawing makes clear how sinuses are formed

6. Draw a picture of the ventricles of the brain and include important passageways

7. What flows through the ventricular system? Where does it travel after it exits the ventricular system? Where does it go to once it finishes circulating around the brain and spinal cord?

Brainstem

8. List 5 major involuntary/autonomic functions that are regulated/controlled in whole or in part by the brainstem

9. Name the three regions of the brainstem and describe a function that is associated with each region:

a. b. c.

Cerebellum

10. The cerebellum is involved in motor control. How does it differ from cortical motor control regions of the brain?

11. Draw a diagram of the cerebellum, label major structures

Think about structures that feed information to cerebellum

Think about structures that the cerebellum sends information to Include this information, perhaps in the form of arrows, in your diagram/picture

Localization/thought questions:

12. Which region of the central nervous system would be damaged if a patient walks like they are drunk?

13. A stroke results in paralysis of the left hand. Which region of the brain was impacted?

14. A stroke results in loss of touch and feeling in the left leg. Which region of the brain was impacted?

15. The Justin Bieber tune you’ve been listening to (you know you have…) initially reaches which part of the brain?

16. Label major components of diencephalon and brainstem in the image below – label the corpus callosum
