Show answer & explanation
Correct answer: C
Explanation
Medulla -
Involuntary actions such as salivation, vomiting, blood pressure, and respiration are controlled by the medulla portion of the hindbrain.
Description of Key Points:
Medulla Oblongata: This is the lowest part of the brain that connects to the spinal cord. It is the center of important involuntary actions such as heart rate, swallowing, coughing, sneezing, and salivation.
Other Options:
Cerebrum: This is part of the forebrain and is responsible for thinking, reasoning, memory, and voluntary muscle movement.
Pons: This is also part of the hindbrain, but its main function is to regulate respiration and relay signals between different parts of the brain.
Hypothalamus: It controls body temperature, hunger, thirst, and emotions.
