What receptors are embedded in the urinary bladder?
Muscarinic receptors are also located on the epithelial lining of the bladder (urothelium) where they induce the release of a diffusible factor responsible for inhibiting contraction of the underlying detrusor smooth muscle.
What is a renal column?
The renal column (or Bertin column, or column of Bertin) is a medullary extension of the renal cortex in between the renal pyramids. It allows the cortex to be better anchored. Each column consists of lines of blood vessels and urinary tubes and a fibrous material.

What tube connects each kidney to the urinary bladder?
ureter. The tube that carries urine from the kidney to the bladder.
What does the renal vein do in the kidney?
The main blood vessel that carries blood from the kidney and ureter to the inferior vena cava (a large vein that carries blood to the heart from the lower part of the body).
What are the capillaries of the kidney?
Within each nephron is a small sac of capillaries called the glomerulus that’s surrounded by Bowman’s capsule. In these capillaries, under tight pressure, materials are constantly being filtered out of the blood. The pressure in each glomerulus is higher than in any other capillary.
What is the outer most layer of the kidney quizlet?
The outer layer of the kidney is called the renal medulla. Both the glomerulus and the loop of Henle make up the renal corpuscle.
Which of the following is the inner layer of the kidney quizlet?
The outermost renal cortex where 85% of the kidneys nephrons are found in the outer renal cortex. And the inner is the renal medulla.
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.
What is a kidney quizlet?
Kidney. Function – extract waste from blood, balance body fluids, form urine, and aid in other important functions of the body. Location – They are located just below the rib cage, one on each side of the spine. Renal Artery.
Which layer of the kidney is blood filtered quizlet?
1. Renal Cortex: outer layer of the kidney that filters blood and removes waste products. 2. Renal Medulla: inner region of the kidney that is divided into regions called renal pyramids.
Where are located the kidneys?
The kidneys can be found underneath the ribcage, on each side of the spine. Pain from the kidneys is felt in the sides, or in the middle to upper back (most often under the ribs, to the right or left of the spine).
What anatomical structures protect the kidneys?
1 – Kidneys: The kidneys are slightly protected by the ribs and are surrounded by fat for protection. On the superior aspect of each kidney is an adrenal gland.
What are the layers of the kidney quizlet?
- Outer Layer. *RENAL CORTEX. -made of corpuscles and convoluted tubules.
- Inner/Middle Layer. *RENAL MEDULLA. -made of loops of Henle and collecting tubules. -location of renal pyramids.
- Cavity Area. *RENAL PELVIS. -cavity which urine flows into before it proceeds to ureters.
What anatomical structures provide protection to the kidneys?
Retroperitoneal anchoring, renal fat pads, and ribs provide protection to the kidney. The renal portal system has an artery between the first and second capillary bed. The others have a vein. The structures found in the renal hilum are arteries, veins, ureters, lymphatics, and nerves.
What are the three layers of the kidney?
The Kidneys Are Composed of Three Main Sections Each kidney consists of an outer renal cortex, an inner renal medulla, and a renal pelvis. Blood is filtered in the renal cortex.
What is the importance of the fatty tissue surrounding the kidneys quizlet?
The fatty tissue surrounding the kidneys is important because: it ensures adequate energy for the adrenal glands to operate efficiently. it stabilizes the position of the kidneys by holding them in their normal position.
Which part of the nephron can be found in the medulla of the kidney?
The glomerulus and convoluted tubules of the nephron are located in the cortex of the kidney, while the collecting ducts are located in the pyramids of the kidney’s medulla.
Which of the listed tissues lines a calyx in the pelvis of a kidney?
Urine drains from the ducts in the papilla into a renal calyx. Each calyx is lined by transitional epithelium, or urothelium. The calyces merge into the renal pelvis. The renal pelvis narrows at the ureteropelvic junction to join the ureter.
What are the two main parts of the nephron quizlet?
What are the two main parts of a Nephron? Glomerulus, and Renal Tubule.
What type of receptors embedded in the urinary bladder wall initiates the micturition reflex?
Normal micturition is a result of stretch receptors in the bladder wall that transmit nerve impulses to the sacral region of the spinal cord to generate a spinal reflex. The resulting parasympathetic neural outflow causes contraction of the detrusor muscle and relaxation of the involuntary internal urethral sphincter.
Which of the following is the inner layer of the kidney?
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 muscles surround kidneys?
- Anterolateral Abdominal Wall.
- Posterior Abdominal Wall.
Where do structures and vessels enter and exit the kidneys?
The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney; it is also the point of exit for the ureters.
What type of connective tissue is renal fascia?
The renal fascia, commonly known as Gerota’s fascia, is a collagenous connective tissue sheath which separates the perirenal fat from the pararenal fat. It may be visualized radiographically and is helpful in the precise localization of abdominal masses.
Where is Gerota's fascia located?
Gerota’s fascia, otherwise known as renal fascia, is collagen-filled, fibrous connective tissue that encapsulates the kidneys and adrenal glands. Gerota’s fascia separates perinephric fat from paranephric fat—the fat in the front and back of the kidney.
What tissue protects the inner lining of the ureter?
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.
What is filtrate and how is it formed in the kidney?
As discussed earlier, filtrate is produced when in the high-pressure glomerulus, plasma components are driven through the filtration membrane and collected in Bowman’s capsule.
What tissue are renal corpuscles found?
Renal corpuscles are only found in the cotex of the kidney. Kidney (400x) Renal corpuscles are circled in black. Surrounding the corpuscles are the convoluted tubules (three of them are circled in blue) made of simple cuboidal epithelial tissue.
Which vein drains into the renal vein?
Renal veinDrains toinferior vena cavaArteryRenal arteryIdentifiersLatinvenae renales
How is the renal vein formed?
The renal vein is formed by the union of two-to-three renal parenchymal veins in the renal sinus. It emerges from the renal hilum anterior to the renal artery and drains into the inferior vena cava at the level of L2.
