Question 13 - Single Best Answer

Bobby is an 8 year old white male with bilateral hearing loss and unsteadiness. He also has flat, segmented sesions on his skin (known as cafe-au-lait spots because they resemble coffee with milk). He is given a diagnosis of vonRecklinghausen's disease. This is an autosomal dominant disorder that is characterized by overgrowth of Schwann cells (from cranial nerve 8 and others in this case. Because of this, the lesion may also be called an acoustic neurilemmoma or acoustic schwannoma). Which limb of the nervous system is involved with this disease?

A) central nervous system
B) peripheral nervous system
C) autonomic nervous system
D) visceral nervous system

D) cell body

Question 16 - Single Best Answer

Classify the type of neuron the pathologist would see upon removal of the lesion causing the symptoms above.

A) bipolar
B) unipolar
C) pseudopolar
