What is the smooth semitransparent membrane that adheres tightly to the outer surface of the kidney?

Renal CapsuleRenal CapsuleRenal CapsuleThe renal capsule is a tough fibrous layer surrounding the kidney and covered in a layer of perirenal fat known as the adipose capsule of kidney. The adipose capsule is sometimes included in the structure of the renal capsule. It provides some protection from trauma and damage.

What is the membrane that surrounds a kidney?

renal capsule, thin membranous sheath that covers the outer surface of each kidney. The capsule is composed of tough fibres, chiefly collagen and elastin (fibrous proteins), that help to support the kidney mass and protect the vital tissue from injury.

What is the name of the smooth muscle layer of the renal artery?

The innermost layer, the tunica intima (also called tunica interna), is simple squamous epithelium surrounded by a connective tissue basement membrane with elastic fibers. The middle layer, the tunica media, is primarily smooth muscle and is usually the thickest layer.

What usually attaches the kidney to the Retroperitoneum?

adipose capsules

Usually, adipose capsules attach the kidneys to the retroperitoneum (the space behind the peritoneum).

What are the calyces?

Your calyces are where urine collection begins. Each kidney has 6 to 10 calyces. They’re on the outer edges of your kidneys. With caliectasis, the calyces become dilated and swollen with extra fluid. It’s usually caused by another condition that affects the kidneys, such as a urinary tract infections (UTI).

Is the smooth inner tissue of the kidney?

The renal medulla is the smooth, inner tissue of the kidney. It contains the loop of Henle as well as renal pyramids.

What surrounds and protects each kidney?

The fibrous capsule is a layer of adipose tissue that surrounds the kidney.

Where is the tunica media?

The tunica media is the middle portion of the vessel wall and contains smooth muscle cells and connective tissue, whereas the tunica adventitia is composed of connective tissue that is often continuous with the surrounding soft tissues.

What is the hilum of the kidney?

The hilus is the point of entry and exit of the renal arteries and veins, lymphatic vessels, nerves, and the enlarged upper extension of the ureters.

What is the afferent arteriole?

The afferent arteriole is an arteriole that feeds blood into the glomerulus. The renal arterioles play a central role in determining glomerular hydraulic pressure, which facilitates glomerular filtration.

What is the outside of the kidney called?

The kidneys are under the ribcage in the back, one on each side. Each adult kidney is about the size of a fist. Each kidney has an outer layer called the cortex, which contains filtering units. The center part of the kidney, the medulla (pronounced: meh-DUH-luh), has fan-shaped structures called pyramids.

What do you call the outermost connective tissue wrapping that surrounds the kidney?

What do you call the connective tissue wrapping that surrounds the kidney? Renal capsule.

Does the kidney have smooth muscle?

There is no a-smooth muscle actin immunoreactivity in the kidney.

Is ureter a smooth muscle?

The ureter is a muscular tube, composed of an inner longitudinal layer and an outer circular layer of smooth muscle.

What is a Trigone?

noun. Also trigonum. Anatomy. a triangular part or area. the area on the floor of the urinary bladder between the opening of the urethra in front and the two ureters at the sides.

How are smooth muscle cells connected?

Smooth muscle cells are connected to each other through regions called adherens junctions. These regions contain many fibrous proteins for strength when the cells pull against each other. The junctions also contain small gaps, which allow the cell membranes of two neighboring cells to join.

What is smooth muscle tissue?

smooth muscle, also called involuntary muscle, muscle that shows no cross stripes under microscopic magnification. It consists of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike striated muscle, contracts slowly and automatically.

Where is smooth muscle tissue found?

Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control.
