Urinary Tract Flashcards
Cranial and caudal poles of right kidney
- Caudate process of liver and right adrenal
2. Ascending colon
Cranial and caudal poles of left kidney
- Left lobe of pancreas and left adrenal
2. Descending colon, mesovarium (in female)
Dorsal surface of kidneys
- Contact lumbar hypaxial mm.
2. Free of peritoneum
Ventral surface of kidneys
- Faces abdominal cavity
2. Covered by parietal peritoneum
Lateral border of kidneys
- Convex
2. Related to abdominal wall/spleen
Medial border of kidneys
- Concave
2. Related to caudal vena cava/abdominal aorta
Renal hilus location
Indented medial border of kidney
Renal hilus contains
Renal b.v., lymphatic, nerves and ureta
Renal pelvis shape
Funnel shaped dilation of ureter
Renal pelvis is located?
Inside renal sinus
Renal pelvis function
Receives urine from papillary ducts → passes it into ureter
Pelvic recess shape and location
Curved diverticula of renal pelvis → project into parenchyma between renal pyramids
Fibrous capsule
Covers surface of kidney
Fibrous capsule consists of?
- Mostly collagen
- Few elastic
→ cannot swell as well as other organs
How is fibrous capsule connected to kidney?
Loose CT, easily stripped from healthy kidney
hard to pull off in necrosopy → pathology
Renal cortex location
Directly inside fibrous capsule (outer layer)
Outer portion of renal parenchyma
Renal cortex
Renal cortex appearance
Granular - renal capsules
Renal corpuscles
Efferent and afferent vessels
Nephron
Structural and functional unit of kidney
Renal crest location
Free edge of medulla facing pelvis
Renal crest formed by?
Fusion of renal papillae
Papillary foramina are open where?
On border of renal crest facing pelvis
Openings of papillary ducts are called?
Papillary foramina
Renal papillae
Apex of renal pyramid → seen in paramedian sections
Renal pyramid
Pyramid shaped medullary substance → represents lobes of kidneys (only seen in paramedian sections)
How many pelvic recesses form each border of pelvis?
5-6
Renal sinus
Space led into by hilus
