Dental Anatomy

When calcospherites fail to fuse during calcification of dentin matrix then
1 Interglobular dentin is formed
2 Dead tracts are found in formed dentin
3 Irregular dentin results
4 None

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

Interglobular Dentin:
Sometimes, mineralization of dentin begins in small globular areas that fail to coalesce into a homogenous mass. This results in�zones of hypomineralization between the globules.
These zones are known as globular dentin or interglobular spaces. Thus, demonstrating defect of mineralization and not of matrix�formation, the dentinal tubules pass uninterruptedly through interglobular dentin.

Physiology

What is the osmolarity of the tubular fluid leaving the early distal tubule?
1) Isotonic to plasma
2) Hypertonic
3) Hypotonic
4) Variable

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

The osmolarity of the tubular fluid leaving the early distal tubule is hypotonic, as it has lost solutes while retaining water.
