There are two true statements here. First, the prostate gland encircles the urethra. It circles around the first part of the urethra, the prostatic urethra. This is why urinary retention is one symptom of prostatic hypertrophy--if the prostate is enlarged, it may close around the urethra, occluding this passage and preventing urine from exiting the bladder. The prostate gland is also ...

Chronic renal failure
Ca2 deficiency (low Ca 2+ diet or hypocalcemia) activates lahydroxylase, which catalyzes the conversion of vitamin D to its active form, 1,25-dihydroxycholecalciferol. Increased parathyroid hormone (PTH) and hypophosphatemia also stimulate the enzyme. Chronic renal failure is associated with a constellation of bone diseases, including osteomalacia caused by failure of ...

37 mm HgGlomerular filtration will stop when the net ultrafiltration pressure across the glomerular capillary is zero; that is, when the force that favors filtration (47 mm Hg) exactly equals the forces that oppose filtration (10 mm Hg + 37 mm Hg).

Mycobacterial meningitis21. The correct answer is D. This patient suffered from tuberculous meningitis, which is demonstrated by the characteristic acid-fast bacilli present in the patients brain tissue. Immunocompromised patients are at risk for developing tuberculous meningitis, which occurs after the central nervous system (CNS) is seeded with mycobacteria that subsequently produce a thick, ...

Rapidly progressive glomerulonephritisThe correct answer is F. The image shows a crescent of epithelial cells and fibrin as well as a hypercellular glomerulus, which together are characteristic of rapidly progressive glomerulonephritis (RPGN). Furthermore, the clinical scenario demonstrates a nephritic syndrome, with hematuria, oliguria, and hypertension, which one would expect with RPGN. In ...

Monozygotic twinsThe correct answer is D. This woman has had a normal delivery of monozygotic (identical) twins. Monozygotes may also develop separately, producing two amniotic sacs, two placentas, and two chorions, but this would not be distinguishable from dizygotic twins. In the case of a single chorion and placenta, the pregnancy must have developed from a single zygote, and in the womb the ...

NADH:NAD+The correct answer is B. This patient is suffering from hypoglycemia related to his alcohol use. Ethanol is metabolized to acetaldehyde, which is then metabolized to acetate (acetaldehyde dehydrogenase). During both steps of ethanol metabolism, NADH is generated from NAD+. With an elevated NADH:NAD+ ratio in the liver, pyruvate is diverted to lactate, PIGwhile oxaloacetate is diverted ...

SplicingThe correct answer is D. Introns are noncoding regions of RNA that are spliced out of mature mRNA. Almost all introns begin and end with 5 GUAG 3. A mutation in one of those nucleotides affects splicing. This type of mutation is one of those found in thalassemia
Answer A is incorrect. Capping of the mRNA occurs at the 5 end as it is being transcribed. A mutation at the 5 end of an ...
