Question 1 of 5
A 9-year-old female patient is brought to the pediatrician because she says 'a heart is in my head.' She reports bilateral headaches of pulsating quality, nausea, and has vomited 4 times. Her headache began approximately 6 hours ago, and says that lights worsen her symptoms. Her eyes are red teary and she reports nasal congestion.

Question 2 of 5

Correct Answer: B
Rationale: The neuron is the basic structural and functional unit of the nervous system, capable of receiving, processing, and transmitting signals.
Question 4 of 5
The effect of a sending neuron on a receiving neuron is typically greater when neurotransmitters bind to the receiving neuron and the synapse is the base of the receiving cell's axon.
Correct Answer: A
Rationale: Synapses closer to the axon hillock (base of the axon) have a greater impact due to less signal attenuation, and more neurotransmitter enhances the effect.
Question 5 of 5
Which division of the human nervous system carries signals to skeletal muscles?
Correct Answer: D
Rationale: The motor system (part of the somatic nervous system) controls skeletal muscle movement, distinct from the autonomic system’s visceral control.
