Q
Applying What You Know!
- Sean was 35 and started noticing some visual symptoms, frequent bouts of imbalance, and memory loss. He hesitates to go to the doctor because he has no pain and thinks that the symptoms will probably “go away soon.” What is wrong with Sean’s attitude towards these symptoms?
A
- Brain tissue is unique and lacks the type of nociceptors that transmit sensation of pain. The brain is, therefore, incapable of sensing painful stimuli.

Q
Applying What You Know!
- Dick is a diabetic. He has been complaining of numbness in his feet. The doctor took great time and care to use cold and warm probes and methodically check areas of his feet repeatedly. Is this necessary?
A
- Thermoreceptors are cold or warm. They are also not spread uniformly across the skin. Doctors use this technique to determine the extent and degree of numbness or sensitivity.
