23 Blood insulin levels were highest 1 hour post meal Production of ketones occur when blood glucose levels are low The amount of ADH that is secreted by the posterior pituitary glands varies with blood osmotic pressure Sperm are produced in the seminal tubules of the testes Secondary Spermatocytes represent the first haploid stage of spermatogenesis Testicular temperature control is accomplished through the actions of the dartos and cremaster muscles. Which of the following cells may become spermatozoa? Spermatogonia Which cells secrete testosterone? Leydig cells Which hormone stimulates the Leydig cells to secrete testosterone? LH (Luteinizing hormone) The function of the epididymis is sperm maturation Which structure is formed by the union of the duct from the seminal vesicle and the ampulla of the vas deferens? Ejaculatory duct A patient with chronic skeletal muscle spasms was placed on an anticholinergic medication. After taking the medication, the patient’s muscle spasms ceased, but now the patient reports a loss of muscle strength. In addition, the patient’s resting heart rate has increased. Explain the effects of the medication the patient received. Acetylecholine causes skeletal muscle contraction. Anticholinergic medication inhibits the Acetylcholine, therefore limiting muscular contraction and thus ceasing involuntary muscle spasms. The patient’s heart rate is slightly increased due to the parasympathetic vagal stimulation being blocked.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
