Show answer Hide answer
Answer: D. both a & b
Explanation
The pituitary gland is medically designated as the hypophysis cerebri due to its anatomical position beneath the brain. This ovoid endocrine structure is connected directly to the hypothalamus via a slender stalk known as the infundibulum. Because both terms correctly identify this vital gland, the option encompassing both names is the most accurate choice. Often called the master gland, the pituitary controls numerous other endocrine glands throughout the human body system. The anterior lobe of the pituitary synthesizes and secretes critical hormones regulating growth, metabolism, and stress responses. Embryologically, the pituitary gland develops from an outpouching of the embryonic pharynx combined with neural tissue from the brain.
Option a names only the hypophysis cerebri, missing the equally valid common English term for the endocrine gland. Option b names only the pituitary gland, ignoring its formal medical designation as the hypophysis cerebri. The infundibulum is the connecting stalk itself rather than the ovoid endocrine gland hanging beneath the hypothalamus.
