Epidural hematoma: bleeding between the dura mater and the skull
Subdural hematoma: bleeding in the subdural space

14. Degenerative diseases p225
Alzheimer’s disease
Parkinson’s disease

15. Cranial nerves p
12 pair of cranial nerves are identified by Roman numerals

16. Cranial Nerve Disorders p229
Glaucoma: destruction of optic nerve (II)
Decreased hearing/deafness: destruction of vestibulochochlear nerve (VIII)

17. Aging and Nervous system p229
The nervous system decreases in size
Speed of processing declines
Vascular degeneration
Age makes it more difficult to acquire new skills, but practice (repetition) enhances skill learning
