Lab 4: Anatomy and Histology of the kidney Flashcards
Define the paravertebral gutter and name a structure that lies in it
The patavertebral gutters are the rounded expanse of ribs formed when the back parts of the ribs curve from the outside edges towards the spinal column.
The kidneys lie in the paravertebral gutter
Describe the position of the right kidney
The right kidney sits just below the diaphragm and posterior to the liver
Describe the position of the left kidney
The left kidney sits below the diaphragm and posterior to the spleen
The kidney is surrounded by two layers of fat.
Name these layers
The perirenal and pararenal fat
Describe the renal sinus
Fat filled compartment that contains branches of the renal artery, vein; major and minor calyces.
Main component is adipose tissue
The segmental branches of the renal artery are known as?
End arteries- arteries which do not anastomose with their neighbors
Which veins drain into the left renal vein?
Left suprarenal vein
Left gonadal vein
The nephron is composed of _____ and _____.
Renal corpuscle
Renal tubule
Renal tubules have a ____ loop of henle and ___ the medulla
Short
Does not penetrate
Juxtamedullary nephrons have a ____ loop of henle and ___ the medulla
Long
extend deep into the medulla
The ureter conducts urine from ____ to ______
Renal pelvis
Urinary bladder
Describe the movement of the urine in the ureter
Peristaltic like contractions propel the urine
This is due to the mucous membrane and large amount of muscle in the ureter wall
What structures lie close to the superior poles of the kidneys?
Adrenal gland / The diaphragm and 12th rib lie at its superior end.
The left kidney is slightly higher up than the right. What other anatomical structure(s) is/are closely related to the superior pole of the left kidney?
Spleen, stomach, and through the diaphragm, the left kidney is also closely related to the 11th rib and pleura
What structure is related to the medial borders of the kidneys?
Psoas major.
Right kidney, the inferior vena cava, renal vessels and ureter are close by.
Left kidney, there is the adrenal gland, renal and suprarenal vessels and ureter.
