Difference Between Proximal and Distal Convoluted Tubule
- Diameter of proximal tubule is larger than that of distal tubule.
- Epithelium of proximal tubule contains a brush boarder, whereas that of the distal tubule contains few short microvili.
- Proximal tubule has an irregular or star shaped lumen. ...

Are the phalanges distal or proximal to the ulna?
The distal phalanges of ungulates carry and shape nails and claws and these in primates are referred to as the ungual phalanges.. History of phalanges Etymology. The term phalanx or phalanges refers to an ancient Greek army formation in which soldiers stand side by side, several rows deep, like an arrangement of fingers or toes.. In animals. Most land mammals including humans have a 2-3-3-3-3 ...
What is proximal medial tibia?
- Aching along the front of the shin with activity.
- The pain may begin as a dull aching sensation after running.
- The aching may become more intense, even during walking, if ignored.
- Pain along the inside (medial) part of the lower leg.
- Generally, develops gradually over weeks/months
- May have swelling in lower leg
Why are kidney tubules lined with simple cuboidal epithelium?
Urinary: Tubules of the Nephron, and collecting tubules/ducts.
- proximal convoluted tubule (red: found in the renal cortex)
- loop of Henle (blue: mostly in the medulla)
- distal convoluted tubule (purple: found in the renal cortex)
- collecting tubule (black: in the medulla)
- collecting duct black: (in the medulla)
Is the pharynx distal or proximal to lung?
The pharynx is the region posterior to the nasal cavity, oral cavity, and larynx that extends from the base of the skull inferiorly until it becomes continuous with the esophagus. The pharyngeal muscles include an external layer: the superior, middle, and inferior constrictor muscles.
How can you tell the difference between proximal and distal convoluted tubules?
0:031:50Proximal vs distal convoluted tubules, histology - YouTubeYouTubeStart of suggested clipEnd of suggested clipSo remember that we just said that the proximal tubules have low columnar epithelium and have a wideMoreSo remember that we just said that the proximal tubules have low columnar epithelium and have a wide brush border. So the distance have low the distal convoluted tubule.
What is difference between DCT and PCT?
PCT: Proximal convoluted tubule (PCT) refers to the convoluted portion of the nephron between Bowman's capsule and the loop of Henle. DCT: Distal convoluted tubule (DCT) refers to the convoluted portion of the nephron between the loop of Henle and the collecting duct.
How is the distal convoluted tubule DCT different from the proximal convoluted tubule PCT in structure or function?
How is the distal convoluted tubule (DCT) different from the proximal convoluted tubule (PCT) in structure or function? The PCT is mainly involved in reabsorption, while the DCT is mainly involved in secretion.
What is the function of the proximal and distal tubules?
The function of the proximal tubule is essentially reabsorption of filtrate in accordance with the needs of homeostasis (equilibrium), whereas the distal part of the nephron and collecting duct are mainly concerned with the detailed regulation of water, electrolyte, and hydrogen-ion balance.
What is the difference between tubular reabsorption and secretion?
The key difference between tubular reabsorption and tubular secretion is that tubular reabsorption involves the removal of some solutes and water from the tubular fluid and their return to the blood, while tubular secretion involves the removal of hydrogen, creatinine, and drugs from the blood and return to the ...
Which is more coiled PCT or DCT?
Ask questions and help others by answering questions....Question Bank, Mock Tests, Exam Papers.The cells present in the Proximal Convoluted Tubule (PCT) have brush border which is capable of absorption.Distal Convoluted Tubule (DCT) is the highly coiled part found in the medulla of the kidney.URINE8 more rows
Why are the proximal and distal segments of the tubule convoluted?
The distal convoluted tubule continues into the cortex from the ascending limb of the loop of Henle. Like the proximal convoluted tubule, this segment of the tubule is called convoluted because it twists about. It is distal because it is further "downstream" from the starting point, the renal corpuscle.
Is DCT longer than PCT?
Histology. The DCT is lined with simple cuboidal cells that are shorter than those of the proximal convoluted tubule (PCT). The lumen appears larger in DCT than the PCT lumen because the PCT has a brush border (microvilli).
