in the male, lh:
stimulates the seminiferous tubules to produce sperm more rapidly.
inhibits the secretion of fsh from the anterior pituitary.
stimulates the interstitial cells to increase their secretion of testosterone.
is referred to as the anabolic hormone because of its marked stimulating effect on protein anabolism.

Explanation:

Question 1 (Top Question - Lymph Structure)

The structure that first receives lymph from lumbar and intestinal trunks, located on \( L_1 \) and \( L_2 \) vertebrae, is the cisterna chyli. Assuming the illustration labels (A - E) have the cisterna chyli at a specific letter (commonly related to lymphatic anatomy, but since the illustration isn't fully visible, if we follow standard anatomy: the cisterna chyli is the first to receive these trunks. However, for the multiple - choice with options A - E, if we assume the correct letter (e.g., if the illustration has cisterna chyli as, say, B (common in some diagrams), but this depends on the illustration. But since the user provided the question, and we need to answer, but without the illustration, we can't be sure. Wait, no, the user's first question is about identifying the letter for the structure (cisterna chyli) that receives lymph from lumbar and intestinal trunks on \( L_1/L_2 \). In standard lymphatic anatomy, the cisterna chyli is that structure. Now, for the second question (Question 148):

Question 148

The tube connecting ovaries to uterus is called uterine tubes, oviducts, or fallopian tubes. So "All of the above are correct" is the right choice.

In males, LH (Luteinizing Hormone) stimulates interstitial cells (Leydig cells) to secrete testosterone. The first option: FSH stimulates seminiferous tubules for sperm production. The second option: Inhibin (not LH) inhibits FSH. The fourth option: Anabolic hormone is more related to growth hormone. So the correct option is "stimulates the interstitial cells to increase their secretion of testosterone".

Answer:

All of the above are correct.
