B) seminiferous tubules
C) liver
D) pituitary
Correct Answer: B
Solution :
Leydig cells or interstitial cells are concerned with somniferous tubules. These cells contain yellow pigment granules and are large polyhedral cells which have ecentric nucleus and small lipid containing vacuoles. They secrete testosteron and other androgens. Ovaries are pair of greyish pink ovoid or almond shaped primary sex organ or female gonads which lie in the upper lateral part. It contains numerous follicles, in which eggs develop and from which they are released in regular cycle. Liver is a large lobed organ in the abdomen of vertebrates that plays an essential role in many metabolic processes by regulating the composition and concentration of nutrients and toxic materials in blood. Pituitary is a pea-sized endocrine gland attached by a thin stalk to the hypothalamus at the base of the brain. It is a bilobed structure- anterior and posterior. The anterior pituitary secretes growth hormone, gonadotrophic, prolactin, TSH and ACTH and posterior pituitary secretes oxytocin and Antidiuretic hormone (ADH).
