What is the inner layer of the kidney?
medulla
The medulla is the inner region of the parenchyma of the kidney. The medulla consists of multiple pyramidal tissue masses, called the renal pyramids, which are triangle structures that contain a dense network of nephrons.
What is the innermost layer of the ureters?
transitional epithelium
The inner layer, the mucosa, is transitional epithelium that is continuous with the lining of the renal pelvis and the urinary bladder. This layer secretes mucus, which coats and protects the surface of the cells.
Where is the ureter tube located?
The ureter is a tube that carries urine from the kidney to the urinary bladder. There are two ureters, one attached to each kidney. The upper half of the ureter is located in the abdomen and the lower half is located in the pelvic area.
Where is the proximal ureter located?
renal pelvis
At the proximal end of the ureter is the renal pelvis; at the distal end is the bladder. The ureter begins at the level of the renal artery and vein posterior to these structures. This ureteropelvic junction usually coincides with the second lumbar vertebra on the left, with the right being marginally lower.
Where does the ureter penetrate the kidney quizlet?
Where does the ureter penetrate the kidney? The ureter, blood vessels, and nerves penetrate the kidney on its medial surface. The fibrous capsule is a layer of adipose tissue that surrounds the kidney.
Where is distal ureter located?
The upper ureter extends from the renal pelvis to the upper border of the sacrum. The middle ureter continues from the upper to lower borders of the sacrum. The distal ureter continues from the lower border of the sacrum to the bladder.
Where is the urethra and ureter located?
The ureter is a small tube, or duct, that connects the bladder and kidneys. Urine passes through the ureter from the kidneys to the bladder. The urethra is the tubular path that connects the bladder to the body’s exterior, allowing urine to exit the body.
Where are the kidneys and ureters located?
They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder.
Where is the ureter located in a female?
It travels with the inferior vesical neurovascular pedicle into the bladder. In females, the ureter runs posterior to the ovary and then deep to the broad ligament and through the cardinal ligament.
Where is urethra located?
The urethra is a tube that connects the neck of your bladder to the urethral opening on your external genitals, where urine exits the body. It is part of the urinary tract system that in descending order includes the kidneys, ureters, bladder, and the urethra.
Where does the ureter originate and exit the kidney?
The ureter originates in the renal pelvis and leaves the kidney through the hilus, located at its medial border (Fig. 7-2). The ureter follows a caudal path that is retroperitoneal in the abdominal portion. At the level of the pelvic cavity, the ureter opens into the urinary bladder.
What connects the renal pelvis with the urinary bladder?
The ureters connect the renal pelvis with the posterolateral surface of the urinary bladder. In an adult, each ureter is about 30 cm long, with innervation coming from the eleventh thoracic to the first lumbar nerves. Urine is propelled toward the bladder by a wave of smooth muscle peristaltic contractions originating near the renal hilus.
Where is the lumen of the ureter narrowest?
The lumen of the ureter is not uniform throughout. It is narrower at the pelviureteric junction, where it crosses the bifurcation of the common iliac artery and where it enters the bladder. A renal stone passing through the ureter can be arrested at any of these sites.
What is the anterior to posterior orientation of the kidney?
Alternatively, the anterior to posterior orientation follows the same pattern: renal vein, renal artery and ureter. It is important to remember this order of vessels and ducts since this is the only thing that will make you able to orient the kidney and differentiate the left one from the right when they are outside of the cadaver.
