Answer:
The correct answer is: is controlled by the somatic nervous system.
Explanation:
The urethra is an organ that is part of the urinary system, and consists of a tube that connects the urinary bladder to the urinary meatus, which is important for the excretion of urine. The urethra has two sphincters, which are muscles with the function to control the exit of the urine: <u>the internal urethral sphincter and the external urethral sphincter</u>.
The external urethral sphincter, unlike the internal one that is composed of smooth muscle, is made of skeletal muscle and is controlled by the somatic nervous system - this is what makes urination voluntary. Being the most external sphincter, it opens after the internal urethral sphincter during the micturition reflex.
Any damage in either sphincter can produce incontinence.
In process
of meiosis. The hypothalamus or the master gland in most animals, including
humans send signals to the ovaries and testes of the reproductive system. In
response to these signals, these ovaries and testes undergoes the sex cells
division which is called meiosis. Spermatogenesis in male gametes, is the
process of sex cell division among sperm cells. On the other hand, oogenesis is
for the female gametes. These cell divisions among respective gametes produces
haploid cell which only contain one pair of chromosomes, in number -23.
In response to this inquiry's question. Simply reproduction.
