Answer:
The correct answer is C.
Explanation:
The respiratory center is divided into 3 main groups, the dorsal respiratory group and the ventral respiratory group, both located in the <u>medulla</u>, and the pontine respiratory group, located in the <u>pons</u>. This last one also divides into two areas: <em>the pneumotaxic and the apneustic center.</em>
During quiet, restful breathing, the dorsal group stimulates the diaphragm and the intercostal muscles for inspiration. Expiration then occurs depending on the elastic recoil of the lungs. When forced expiration is required, the ventral group activates.
Answer:
The correct answer is option C, PRL and oxytocin.
Explanation:
Prolactin released by the pituitary gland which is stimulated by the hypothalamus is responsible for the alveoli producing milk. Prolactin hormone rises when an infant suckles. Oxytocin causes small muscles around the alveoli to produce the milk via milk ducts.
Oxytocin travels with the bloodstream to the breast, where it causes contraction of the myoepithelial cells. Prolactin has an important function in maternal behavior. An increase in prolactin levels decreases sex hormone levels.
Thus, the correct answer is option C, PRL and oxytocin.
