The question is incomplete as it does not have the options which are:
- estradiol; pituitary gland
-
testosterone; hypothalamus
-
leptin; hypothalamus
-
leptin; pituitary gland
Answer:
leptin; hypothalamus
Explanation:
Gonadotropin hormones are the peptide hormones released by the nerve cells of the hypothalamus which stimulates the anterior hormone to release the gonadotropins like the LH and FSH hormones.
The GnRH hormone is released when the leptin, a protein hormone secreted by the adipocytes stimulates the GnRH neurons of the hypothalamus to release the hormone in both males and females.
Thus, leptin; hypothalamus is the correct answer.
Answer:
The correct option is;
-Eccentric Contraction
Explanation:
The releasing of the muscles slowly to become longer under the effect of a load is known as eccentric contraction
An example of eccentric contraction is the elongation of the curl biceps as the load of the dumbbell is lowered down after lifting, such that while in the process of lowering rather than dropping the dumbbell down the biceps remain in contraction so as to maintain control of the descent
Along with eccentric contraction, isometric contraction and concentric contraction make up the three phases of muscles and tendon movement.
