The following is incorrect regarding the peripheral nervous system:
IS
Ethosuximide is a drug used to treat epilepsy, particularly absence seizures. It blocks ion channels found specifically in the dendrites.
How would this help prevent seizures?
What would be the advantage of ethosuxamide over a less targeted drug that affected all neuronal ion channels?
The thalamus has been described as a “switchboard.” Explain why, by describing the pathway of somatic sensory information from the receptors to the cerebral cortex.
Case Study:
Princess Leia has asthma, and had to use her inhaler before taking her physiology exam. Later, in the physiology laboratory, she measured her pulse rate and blood pressure and found them to be higher than usual. The following week, after administering some drugs (epinephrine, atropine) she later developed a severe headache and dry mouth. When she looked in the mirror she noticed that her pupils were dilated.

They were initially diagnosed with Reynauds (which is caused by an overactive sympathetic nervous system cutting off blood flow to the hands in the cold), but recently they have been experiencing issues with fine motor control in their hands, and the doctor is concerned that it could be Multiple Sclerosis.
