Cortisol is released from the:
Correct answer: B. Adrenal cortex
- A. Parathyroid
- B. Adrenal cortex
- C. Hypothalamus
- D. Posterior pituitary
Explanation
Cortisol is released by the adrenal cortex in response to stress and low blood glucose levels. It helps regulate metabolism, immune function, and blood pressure, aiding the body's response to stress. Cortisol also plays a role in suppressing inflammation and mobilizing energy reserves during times of need. Its secretion is tightly regulated by the hypothalamus and pituitary gland through the hypothalamic-pituitary-adrenal (HPA) axis.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
