List the 3 stages of the kidney development in intrauterine life (embryo)
The pronephros
The mesonephros
The metanephros
The excretory ducts of the urogenital system enter a common cavity, called_____
The cloaca
The urogenital system can be divided into_______, namely;
The urinary system
The genital/reproductive system
At the beginning of the 4th week, the pronephros are represented by ____ in the _____ region
7 to 10 cell groups in the cervical region
At ______ week the pronephros disappears
At 4th week
The urogenital ridge is formed in the _____
The mesonephros
The Bowman’s capsule is formed around _______?
The glomerulus
The urogenital ridge is formed in the ______?
Mesonephos
The metanephron is also known as
Permanent kidney
The metanephros appears in _____ week
In the 5th week
The excretory units develop from ____
The metaphoric mesoderm
The ureteric bud gives rise to:
- Ureter
- Renal pelvis
- Major and minor calyces
- 1million to 3million collecting tubules
Continuous lengthening of the secretory tubule results in the formation of ______
- The proximal convoluted tubule
- Loop of hence
- Distal convoluted tubule
The kidney develops from 2 sources, namely;
- The metaphoric mesoderm (Excretory unit)
- The ureteric bud (collecting system)
Bladder defects includes;
- Urachal fistula
- Urachal cyst
- Urachal sinus
- Exstrophy of the bladder
- Exstrophy of the cloaca
The epithelium in both male and female sexes originated in the _______
Endoderm
In the male, the definitive urogenital sinus develops into the _____
The penile urethra
3 portions of the urogenital sinus includes:
- The urinary bladder
- The pelvic part of the urogenital sinus
- The phallic part of the urogenital sinus
The layer of the mesoderm between the primitive anal canal and the urogenital sinus is _____
The Urorectal septum
During the 4th - 7th week of the bladder and urethra development, the cloaca divides into:
- Urogenital Sinus (anteriorly)
- Anal Canal (posteriorly)
During fetal life ____ is responsible for excretion of waste product?
The placenta
Where is the kidney located?
The kidney is located in the retroperitoneal space (potential space) between the abdominal wall and abdominal cavity
Abnormal location/defect of the kidney
- Pelvic kidney/Pelvic Ectopic Kidney
- Horseshoe kidney
- Accessory renal arteries
Formation of urine begins in ______ during early fetal development
Gestation
At _____ week, the pronephros disappears
At the end of 4th week
The mesonphros are derived from _____
Intermediate mesoderm
At _____ week, the first secretory tubules of the mesenphros appears
At early 4th week
The mesonephros and gonads are attached to the posterior abdominal wall by _______
A broad urogenital mesentery
The ridge formed in the mesonephros is called _______
Urogenital ridge
Newly formed collecting tubule is covered at it’s distal end by ______
A metanephoric tissue cap
Collecting tubules of the 5th and successive generations forms the _____
The renal pyramid
The kidney is said to be positioned in the pelvis instead of the abdomen is referred to as _______
The Pelvic Kidney/ Pelvic Ectopic Kidney
When two kidney fuses together to form a u shape, is referred to ______
Horse shape Kidney
The kidney is located/positioned in _____
The retroperitoneal space (potential space) between the abdominal wall and abdominal cavity
______ is the responsibility/function of the placenta in the fetal life
Excretory of waste product
