    can any1 xplain me q11?? renal pyramid is d cortex region which invaginates into renal medulla.loop of henle is present in medullary region and there4 is not a part of renal pyramid

      The convoluted tubules are found in the cortex while the pyramid like struture s found in the medulla. Even the loop of henle is found in the medulla which takes a turn to re-enter into the the cortex. This turn causes the pyramid-like structures in the medulla…… 🙂

      Renal pyramids are parts of renal medulla and not of renal cortex. Thus the renal pyramids consist of loop of Henle and collecting duct.The region between the pyramids where the cortex extends as renal columns are called as columns of Bertini

      No renal pyramid is thr part of the renal medullary region.the coryex extends between these pyramids and forms columns which are known as columns of Bertini.so the convoluted tubules are not present in thr medulla of the kidneys

    i think the ans for 15th question shld be that urine will continue to collect normally in urinary bladder…….because there is no relation between stretch receptors and filling the urine…..

      absolutely ryt!! wall of urinary bladder consist of specialized transitional epithelial tissue which has great power of distention, so urine will continue to collect normally, but, brain will not be able to sense it.

      U r wrong. Actually if the receptors are removed then how will the flow of urine stop??? this is why micturition will continue non-stop…. 😉

      the strech receptors means spinchture muscles and these musles are responsible for micturition that’s why if they are removed then micturion will continue

    it’good for me,this teste is very intersting.

    in q 15, shouldn’t the answer be no micturition? As no stretch receptors present, no signal will be sent to CNS, so how will it direct detrusor muscles for micturition?

        What happens is that stretch receptors sends signals to brain to cause contraction of the bladder via detrusor muscle.this muscle has an action of expelling a substance.SO IF RECEP. Are damaged,these muscle will not contract and sphincter muscles present b/w urethra and bladder opening will not relax hence there will be no micturition.However,since bladder is made of transitional epithelium that has a great power to contract in order to accomodate more urine as long as it can.
        That’s all

      Kidneys will continue to form n excrete d urine even if the detrusor muscles r removed…so dere is no link b/w d formation of urine n detrusor muscles….if they are removed, brain will nt sense d nerve endings n d internal urethral sphincter will relax automatically n micturition will continue.

        According to the micturation reflex as given in the NCERT, strectch receptors help in sending the signals to the brain. The brain then depending on the amount of urine stored in the urinary bladder will give the signal of either opening or closing of the sphicter muscles ….But according to Q15 if the receptors are removed completely ….no signal will be sent to the brain wich in turn will have no response to the sphincter muscles and thus the spincter muscles wud remain as it is (closed)…..the urin ewill continue to collect in the urinary bladder
