Answer:The vagina and the penis are the last passageway out of the reproductive system.
The testes and the ovaries perform similar function.
The Sperm duct and the Fallopian tube perform similar function
Explanation:The penis is the exit out of the male reproductive system,it is through the penial opening that seminal fluid leaves the male reproductive system into a female vagina during coupulation.
The testes is the home for the production of the male spermatozoa while the ovaries contains the ovules( the (sex cell).
The Sperm duct does the job of transportation of the seminal fluid as the Fallopian tube also transports the fertilized egg for implantation.
These are used as Potentiate pain relief.
Medications that might possibly affect painful symptoms including opioid analgesics, anticonvulsants , tricyclic antidepressants, capsaicin, benzodiazepines and skeletal muscle relaxants were gradually withdrawn during the study‐washout period. Paracetamol was allowed as rescue medication.
Tricyclic antidepressants are the most common type of antidepressant used for pain. These antidepressants inhibit the reuptake of serotonin and norepinephrine at the synapse, but do so differentially according to chemical structure.
<h3>How Antidepressants Work in Pain Management?</h3>
The explicit way in which antidepressants are effective in pain management remains unknown, but multiple mechanisms are likely to be involved.
Perhaps the most popular theory is that antidepressants exert their effects on serotonin and norepinephrine, particularly along the descending spinal pain pathways. Antidepressants may also exert adjunctive therapeutic influences through histamine receptors as well as modulation of sodium channels.
