Question

which of the following contains chemoreceptors?
multiple choice
medulla oblongata
pons
thalamus
spinal cord

Explanation:

Chemoreceptors are specialized cells that detect chemical changes. The medulla oblongata contains central chemoreceptors which play a crucial role in regulating respiration by detecting changes in the pH of cerebrospinal fluid (which is influenced by carbon dioxide levels in the blood). The pons is mainly involved in regulating the rate and pattern of breathing but does not have chemoreceptors in the context of the question. The thalamus is a major relay center for sensory and motor signals. The spinal cord is involved in transmitting neural signals between the body and the brain but does not house the chemoreceptors relevant to this question.

Answer:

Medulla oblongata
