Answer:
The best answer to the question: When the corpus luteum degenerates:___, would be, E: All of the above.
Explanation:
The process of human female reproduction is a very complex one. But center in it is the corpus luteum, a structure that develops from a follicle in the ovaries and which will be responsible for producing estrogens and progesterones to maintain pregnany in case there is egg fertilization, or, the dismantling of everything by decaying and thus stopping the outpour of these gonadal steroids. When fertilization occurs, the corpus luteum, by producing estrogen and progestorone, inhibits the further production of LH and FSH, and thus the entire process for a successful pregnancy takes place. But when this does not occur, LH and FSH increase again, progesterone, most especially, decreases, and as a result, the endometrium, which had been prepared for implantation, sloughs off. This is why the answer is E.
Answer: B. Sarcoplasmic reticulum
Explanation: The sarcoplasmic reticulum is the name given to the organelle in the muscle cell, in charge of the storage and regulation of the intracellular calcium levels. It is the smooth endoplasmic reticulum in muscle cells, it means that it does not have ribosomes in its surface.
Option A. Incorrect. A SARCOMERE is the functional and anatomic unit of the striated muscle (skeletal muscle and heart muscle). This word comes from the greek: <em>sarkos (meat), meros (part). </em>That is reason you could find other structures of the muscle cell with this root (SARCO...).
Option C. Incorrect. "Arcolemma" this word does not exist. But if it refers to SARCOLEMMA, this word means: <em>sarko (meat), lema (cortex) </em>in greek<em>. </em>It is the plasma membrane of the muscle cells.
Option D. Incorrect. The SARCOPLASM, comes from the greek: <em>sarko (meat), plasm (matter). </em>This structure is the citoplasm of the muscle cells.
In conclusion, the word SARCOPLASMIC RETICULUM, refers to a <em>structure of the muscle cell, </em>that in this case, is the RETICULUM or the SMOOTH ER.
