Kidney development caudally (downward) and connect with the bladder, thereby forming the ureters. The ureters will carry urine from the kidneys to the bladder for excretion from the fetus into the amniotic sac. As the fetus develops, the torso elongates and the kidneys rotate and migrate upwards within the abdomen which causes the length of the ureters to increase. Kidney development Kidney development, or nephrogenesis, describes the embryologic origins of the kidney, a major organ in the urinary system. This article covers a 3 part developmental process that is observed in most reptiles, birds and mammals, including humans. Nephrogenesis is often considered
Neurogenic bladder dysfunction Neurogenic bladder dysfunction Neurogenic bladder dysfunction, sometimes simply referred to as neurogenic bladder, is a dysfunction of the urinary bladder due to disease of the central nervous system or peripheral nerves involved in the control of micturition (urination). Neurogenic bladder usually causes difficulty - or full inability - to pass urine without use of a catheter or other method. Any condition that impairs bladder and bladder outlet afferent and efferent signaling can cause neurogenic bladder. It is often associated with spinal cord diseases (such as syringomyelia/hydromyelia), injuries (like herniated disks), and neural tube defects including spina bifida. It may also
