Flashcard 1:
Q: What are the vital involuntary functions controlled by the medulla?
A: The medulla controls vital functions such as heartbeat, breathing, and blood pressure.
Flashcard 2:
Q: How does the medulla regulate respiratory functions?
A: It contains centers that regulate the rate and depth of breathing based on CO2 levels in the blood.
Flashcard 3:
Q: What is the role of the medulla in heart rate control?
A: The medulla regulates heart rate by sending signals to the heart muscles to speed up or slow down contraction.
Flashcard 4:
Q: How does the medulla ensure coordination in swallowing and digestion?
A: It controls reflex actions like swallowing, vomiting, sneezing, and coughing.

Q: Why is the medulla important for maintaining blood pressure?
A: It regulates the constriction and dilation of blood vessels to maintain optimal blood pressure levels.
Flashcard 6:
Q: What is the connection between the medulla and the autonomic nervous system?
A: The medulla controls the autonomic nervous system, particularly the sympathetic and parasympathetic responses.
Flashcard 7:
Q: How does damage to the medulla affect basic body functions?
A: Damage can severely impair basic functions like breathing and heartbeat, which can be life-threatening.
Flashcard 8:
Q: What reflexes are controlled by the medulla?
A: Reflexes like sneezing, coughing, and swallowing are governed by the medulla.
