Biology - Neural Control and Coordination Question with Solution | TestHub
The autonomic nervous system controls cardiac activities in response to various inputs from the following EXCEPT:
Options:
Answer:
Solution:
The autonomic nervous system regulates cardiac activities through the cardiovascular centre located in the medulla oblongata. This centre receives inputs from various sensory receptors:
Proprioceptors monitor the position of limbs and muscles, sending signals to increase heart rate during physical activity.
Baroreceptors monitor changes in blood pressure in major arteries (like the aorta and carotid arteries) and send signals to adjust heart rate accordingly.
Chemoreceptors monitor the chemical composition of blood (such as levels of oxygen, carbon dioxide, and pH) and provide inputs to regulate cardiac output.
Photoreceptors are located in the retina of the eye and are responsible for detecting light for vision. They do not provide input to the autonomic nervous system for the control of cardiac activities.
Answer: Photoreceptors.
