QUESTIONS AND
ANSWERS 2026 - 2027
The medullary cavity is filled with ______________ and is located in
the ___________ of the long bone
A. red marrow, diaphysis
B. red marrow, epiphyses
C. yellow marrow, diaphysis
D. yellow marrow, epiphysis
C. yellow marrow, diaphysis
- Yellow marrow, or fat, is found in the medullary cavity within the shaft
of the long bones. Remember that epi means above or upon, so the
epiphysis is the ends of the bone and the diaphysis is the shaft.
This works for epidermis as well! The epidermis is the layer above the
dermis.
Individuals affected with Marfan syndrome tend to be tall, with
disproportionately long arms. Which of the following types of
connective cells divide and push the epiphysis away from the
diaphysis in the course of human growth?
a. Osteocytes
b. Fibrocytes
c. Keratinocytes in the stratum basale
d. Chondrocytes
e. Both a and d are correct
d. Chondrocytes
paracrine signaling are...

QUESTIONS AND
ANSWERS 2026 - 2027
Cholesterol is a lipid and is hydrophobic. Even though thyroid hormone
is made from the hydrophilic tyrosine, the change in structure balances
charges and makes it hydrophobic.
Progesterone and aldosterone are hydrophobic steroids derived
from
A. Tyrosine
B. Peptides
C. Catecholamines
D. Cholesterol
D. Cholesterol
-All steroid hormones are cholesterol based. Any time you see a
hormone with STERONE in the name, it is a STERoid hormONE.

A. hydrophobic
B. ester
C. ionic
D. peptide bond
D. peptide bond
