ACTH is secreted from the anterior pituitary in response to corticotropin-releasing hormone from the hypothalamus. corticotropin-releasing hormone is secreted in response to many types of stress, which makes sense in view of the stress management functions of glucocorticoids.
9-13 cm: With an ultrasound evaluation, the normal kidney size is 9-13 cm. One kidney may be up to 1.5 CM difference in size from the other and still be in acceptable range. Kidney sizes in females may be some smaller than in males but evenso a kidney smaller than 9 CM is abnormally small.
Each is 11-14 cms (5-6 inches) long and is bean-shaped. It is very difficult to examine a normal kidney because they are far back when examined from the front, and behind a lot of muscles when examined from the back. From the kidneys, the collecting systems funnel the urine into tubes (ureters) go down to the bladder.ach is 11-14 cms (5-6 inches) long and is bean-shaped.
