Read the following statements and find out the incorrect statements. a.Adenohypophysis consists of two portions, pars distalis and pars intermedia. However, in humans, the pars intermedia is almost merged with pars distalis. b. The pars distalis is called anterior pituitary and pars intermedia called posterior pituitary. c. Neurohypophysis is called a pars nervosa and store and release two hormones called oxytocin and vasopressin (ADH). d. Anterior pituitary releases 9 hormones and pars intermedia releases only one hormone (MSH). e. Pars distaliss produces GH, PRL, TSH, ACTH, LH and F SH.A. a and b B. b and d C. d and e D. c and d |

Answer» Correct Answer - B The pars distalis is called anterior pituitary and pars nervasa called posterior pituitary (c ). Neurohypophysis (pars nervosa) also known as posterior pituitary, stores and releases two hormones called oxytocin and vasopressin, which are actually synthesised by the hypothalamus and are transported axonally to neurohypophysis. d. Anterior pituitary release 6 hormones as growth hormone (GH), prolactin (PRL), thyroid stimulating hormone (TSH), adrenocorticotrophic hormone (ACTH), luteinizing hormone (LH) and follicle stimulating hormone (FSH), and pars intermedia releases only one hormone (MSH) |
