Kilgore Trout, a mortician at Final Rest Funeral Home, prepares a body on Tuesday and must shave it again on Thursday. Why?
the sweat glands released their product, causing the hair to grow
the skin retracted from the hair follicles
during the process of decomposition, the hairs grew out of the follicles
the skin grew out, forcing the hair out of the follicles
The Correct Answer is B
A. the sweat glands released their product, causing the hair to grow
Hair does not grow postmortem, and sweat gland activity ceases after death.
B. the skin retracted from the hair follicles
After death, the skin dehydrates and shrinks, which can cause the hair shaft to appear longer, giving the illusion that hair has grown, even though it hasn't.
C. during the process of decomposition, the hairs grew out of the follicles
Hair cannot grow after death because cellular metabolism and mitosis cease.
D. the skin grew out, forcing the hair out of the follicles
Skin does not grow postmortem; this is scientifically inaccurate.

Explanation
A. thin skin has five strata

B. thin and thick skin have abundant hair follicles
Thick skin lacks hair follicles entirely. Hair is present only in thin skin.
C. thick contains a stratum lucidum, corneum & granulosum
These three layers are prominent in thick skin, providing extra protection in high-friction areas like palms and soles.

Correct Answer is A
Explanation
A. hyaluronic acid + proteoglycan monomers: Hyaluronic acid forms the central stalk (handle of the "toilet brush"), and proteoglycan monomers attach along its length, forming a large aggregate that traps water and gives ground substance its gel-like consistency.
B. reticular fibers + collagen fibers: These are structural protein fibers in connective tissue but are not components of proteoglycan aggregates.
C. chondroblasts and chondroclasts: These are cartilage cells involved in formation (chondroblasts) and resorption (chondroclasts) but not part of the ground substance's molecular structure.
D. collagen fibers + fibroblasts: Collagen fibers are structural; fibroblasts produce extracellular matrix components, but neither directly forms the proteoglycan aggregate.
