Explanation / Answer

Answers :-

1.option :-'b'-medial surface of spleen.

Explanation :Anatomically, the pancreas is divided into the head of pancreas, the neck of pancreas, the body of pancreas, and the tail of pancreas. The head is surrounded by the duodenum in its concavity. upper part of the front of the head. It is directed at first, upward and forward, and then upward and to the left to join the body;  The tail ends by abutting the spleen.

2.option :-'c'-hyper trophied muscles of neck.

3.option :-'a'-true.

Explanation :The renal papilla is the location where the renal pyramids in the medulla empty urine into the minor calyx in the kidney.

4.option :-'c'-final part of ascending limb of henle and afferent Arterioles.

Explanation :-

The juxtaglomerular apparatus is a specialized region of the nephron responsible for production and secretion of the enzyme renin, involved in the renin-angiotensin system. This occurs near the site of contact between the thick ascending limb and the afferent arteriole. It contains three components: the macula densa, juxtaglomerular cells, and extraglomerular mesangial cells
