Answer:
Trace the sperm from where they are produced to where they are ejaculated.
Explanation:
<u>The testicles</u> <em>are the site of the scrotum where semen is produced</em>. <u>The epididymis</u> <em>is a coiled structure that crowns the testicles and receives immature sperm from the testicles and stores them for several days. </em><u>When ejaculation occurs</u>,<em> semen is expelled from an</em> <u>extremity of the epididymis</u> <em>into the</em> <u>vas deferens</u>. <em>Subsequently, semen travels through the</em> <u>vas deferens</u> <u>to the spermatic cord</u> <em>in the pelvic cavity beyond the ureter and behind the bladder</em>. <em>There</em>, <em>the</em> <u>vas deferens</u> <em>join with the</em> <u>seminal vesicle</u> <em>to form the ejaculatory duct, which crosses</em> <u>the prostate</u> <em>and empties into</em> <u>the urethra</u>. When ejaculation occurs, <em>rhythmic muscle movements propel sperm forward.</em>
Answer:
B. Serotonin is a biogenic amine but not a catecholamine.
Explanation:
Catecholamines are the molecules which have an aminolaterral chain with a chatecol and an amino group on their structure. Also, catecholamines are derived from an aminoacid called tyrosine. Instead, Serotonin is derived from an aminoacid called tryptophan and its structure does not contain the chemical compounds to be a catecholamine.
