Which hormone shows the highest peak during the luteal phase?
Progesterone
LH
FSH
Estrogen
The Correct Answer is A
A. Progesterone: During the luteal phase, the corpus luteum produces the highest levels of progesterone, which is crucial for preparing the uterine lining for potential implantation.
B. LH: Luteinizing hormone (LH) peaks just before ovulation, not during the luteal phase.
C. FSH: Follicle-stimulating hormone (FSH) is primarily active during the follicular phase and has lower levels during the luteal phase.
D. Estrogen: While estrogen levels do rise during the luteal phase, they do not peak as high as progesterone does.

Correct Answer is D
Explanation
Trabeculae: These are thin connective tissue strands that extend from the capsule of the lymph node into the interior. They help to divide the lymph node into distinct compartments or regions, which include the cortex (outer area) and medulla (inner area). This compartmentalization is important for the organization and function of the lymph node, allowing it to efficiently filter lymph and facilitate the immune response.
