Options
- A(A)-(IV), (B)-(I), (C)-(II), (D)-(III)
- B(A)-(IV), (B)-(I), (C)-(III), (D)-(II)
- C(A)-(I), (B)-(IV), (C)-(III), (D)-(II)
- D(A)-(I), (B)-(IV), (C)-(II), (D)-(III)
Correct answer
B. (A)-(IV), (B)-(I), (C)-(III), (D)-(II)
Step-by-step solution
Pars distalis (anterior pituitary) secretes hormones such as prolactin, growth hormone, TSH, ACTH, LH, and FSH. Pars intermedia secretes only one hormone called melanocyte stimulating hormone (MSH). Pars nervosa (posterior pituitary) stores and releases oxytocin and vasopressin, but does not synthesise them. The hypothalamus produces releasing and inhibitory hormones, and also synthesises oxytocin and vasopressin which are transported axonally to the pars nervosa. Thus, the correct match is (A)-(IV), (B)-(I), (C)-(
