ANHB2214 Week 10

What makes up the Juxtaglomerular apparatus?

Juxtaglomerular cells, Macula densa

What is the projection of the medulla into the renal cortex called?

Medullary ray

What type of tissue lines the bladder?

Transitional epithelium

What vessel is a branch of the interlobular artery?

Afferent arteriole

What are the foot processes on podocytes?

Pedicels

What is a renal pyramid and its associated cortex referred to?

Lobe

The region of the kidney containing glomeruli is called the:

Cortex

The region of the kidney containing proximal convoluted tubules and distal convoluted tubules is called the:

Cortex

The region of the kidney containing long loops of Henle and larger collecting ducts is called the:

Medulla

Regions of cortex with texture similar to that of the medulla, containing straight distal tubules and collecting ducts, are called:

medullary rays

The end of each medullary pyramid through which collecting ducts open into a calyx is called a:

Papilla

The space into which one medullary pyramid drains is called one:

Calyx

A principle function for the proximal convoluted tubule is:

Active resorption of nutrients from ultrafilrate back into the blood.

A principal function for the loop of Henle is:

establishment of the medullary concentration gradient

Epithelial cells lining the proximal convoluted tubule:

Have an apical brush border of microvilli for active absorption from the lumen.
Have basal infoldings and interdigitations with adjacent cells for increased basal membrane surface area.
Have many mitochondria to provide energy for active transport against a concentration gradient .
Are cuboidal.

The proximal convoluted tubule is:

several times longer than the distal convoluted tubule.

Epithelial cells lining the thin limb of the loop of Henle:

simple squamous.

Epithelial cells lining collecting ducts:

simple cuboidal.

The macula densa consists of:

closely-packed nuclei in the epithelium of the distal convoluted tubule.

Arteries which form arches along the border between the cortex and the medulla of the kidney are called:

arcuate arteries
