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.

Explanation
A. arrector pili muscles; skeletal
Arrector pili muscles are not voluntary, and skeletal muscle is under voluntary control.
B. apocrine pili muscles; smooth
“Apocrine pili” is not a valid term. Apocrine glands are sweat glands, not muscles.
C. arrector pili muscles; cardiac
Cardiac muscle is found only in the heart and is not associated with skin or hair.
D. arrector pili muscles; smooth
These small involuntary muscles are attached to hair follicles and made of smooth muscle, which contracts to produce goosebumps (piloerection) in response to cold or emotional stimuli.
Correct Answer is D
Explanation
A. growth hormone
Deficiency in GH during childhood leads to dwarfism or delayed growth, so it’s definitely a suspect in short stature.
B. thyroid hormone
Thyroid hormone plays a critical role in metabolism and skeletal growth. Its deficiency can cause growth delays.
C. sex hormones
Estrogen and testosterone influence growth plate closure and stimulate growth during puberty. Imbalance can lead to short stature or delayed puberty.
D. calcitonin
Calcitonin helps regulate calcium levels, but it has a minor role in growth. Deficiency or excess does not cause short stature.
