Work Step by Step
When the question asks which statement is incorrect, that means we are looking for which statement is false.
Option a. is incorrect. The hypothalamus lies superior to the pituitary. This statement is true; therefore, it is not the correct answer because we are looking for the false statement.
Option b. is incorrect. The anterior pituitary releases thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), prolactin (PRL), growth hormone (GH), and the gonadotropic hormones luteinizing hormone (LH) and follicle stimulating hormone (FSH). This statement is true; therefore, it is not the correct answer because we are looking for the false statement.
Option c. is correct. This statement is false because the anterior and posterior pituitary do not communicate with one another; rather, the hypothalamus communicates with them to direct them to release hormones. If this statement is false, then it is the correct answer.
Option d. is incorrect. The axons of neurons lying in the hypothalamus run into the posterior pituitary. This statement is true; therefore, it is not the correct answer because we are looking for the false statement.
