Current Question (ID: 14570)

Question:

The neurocenter for the activity of the Heart is located in

Options:

1. Pons
2. midbrain
3. medulla oblangata
4. cerebrum

Solution:

The neurocenter for the activity of the Heart is located in the medulla oblongata. It is responsible for regulating and controlling the autonomic nervous system, including the sympathetic and parasympathetic nervous systems that affect the heart rate, blood pressure, and cardiac output. The medulla oblongata contains specialized nerve cells that form the cardiovascular center, which receives sensory information from baroreceptors and chemoreceptors and adjusts the heart rate and blood pressure accordingly. The sympathetic and parasympathetic nerves originate from the medulla oblongata and provide the necessary neural signals to regulate the activity of the heart.
