Peter is 10 years old and Paul is 34. Where would you find hyaline cartilage in Peter's long bones but not in Paul's?
medullary cavity
epiphyseal line
ends of the bones
epiphyseal plate
in periosteum
The Correct Answer is D
A. medullary cavity
This cavity holds marrow (red or yellow), not cartilage.
B. epiphyseal line
The epiphyseal line in adults is a remnant of the epiphyseal plate, but does not contain cartilage.
C. ends of the bones
Both Peter and Paul have articular hyaline cartilage at the ends of long bones for joint function.
D. epiphyseal plate
Only children like Peter have an epiphyseal plate (growth plate), which is made of hyaline cartilage. This area allows for bone lengthening during growth and becomes the epiphyseal line in adults like Paul.
E. in periosteum
The periosteum is a connective tissue membrane around bone-not cartilage.

Correct Answer is B
Explanation
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.
Correct Answer is B
Explanation
A. transitional epithelium - specialized for stretch: This is correctly matched. Transitional epithelium lines the urinary bladder and stretches to accommodate urine volume changes.
B. pseudostratified epithelium - multiple layers for protection: This is mismatched. Pseudostratified epithelium appears to have multiple layers due to nuclei at different levels, but all cells touch the basement membrane, so it is a single layer and not primarily for protection.
C. simple cuboidal - found in kidneys, glands, liver: Correctly matched. Simple cuboidal epithelium is commonly found in these organs and is involved in secretion and absorption.
D. keratinized stratified squamous - epidermis of skin: Correctly matched. This type of epithelium forms the outer layer of skin and provides protection against abrasion and water loss.
