1. what does the peripheral nervous system (pns) do?

a. controls involuntary body functions

1. what is the primary role of the autonomic nervous system (ans)?

a. to transmit commands to muscles
b. to carry sensory information to the cns
c. to regulate voluntary movements

1. which condition involves the immune system attacking the myelin sheath of neurons?

a. epilepsy
b. parkinson’s disease
c. multiple sclerosis (ms)
d. alzheimer’s disease

1. what is the primary cause of parkinson’s disease?

a. degeneration of the spinal cord

Explanation:

1. Alzheimer's Disease is defined by progressive memory loss and cognitive decline, distinguishing it from the other listed disorders.
2. The Parasympathetic Nervous System is the "rest and digest" branch of the autonomic nervous system, counteracting the sympathetic system's "fight or flight" response.
3. Serotonin is a neurotransmitter well-documented to regulate mood, sleep, and appetite, unlike the other options with different primary roles.
4. The Peripheral Nervous System acts as the communication link between the Central Nervous System (CNS) and the body's tissues.
5. The Autonomic Nervous System controls involuntary, unconscious bodily functions such as heart rate and digestion.
6. Multiple Sclerosis is an autoimmune disorder where the immune system attacks the myelin sheath surrounding neurons.
