Question

At the time of sexual excitation, muscles in penis &ndash;a)Relaxedb)Contractedc)Collapsedd)NoneCorrect answer is option 'A'. Can you explain this answer?

Answer

The correct answer is (A) because :-

Typically after ejaculation or orgasm, sexualarousal wans. As that erection goes down. The same sort of thing happens in people with vaginas as well. During sexual activity, the body and genitals are aroused. This includes extra blood rushing to the genital region, swelling in that area, relaxation and lubrication of the vaginal canal, etc. Once sexual activity ends, those signs of erection will subside. If desired, after a 'refractory period', erection can generally be achieved again.

That's all☺

Answer

As the term says excitement it is before the coitus... So the muscles are relaxed (at the beginning of penis) so that blood could enter the penis easily so that it could be erected... Nitric oxide plays important role here.. If there is nitric oxide in sufficient amount... Blood could easily come and fills the sinuses in penis... Which is the reason for erection :)

Answer

At the time of sexual excitation, muscles in penis are relaxed.
The muscles in the penis play a crucial role in sexual arousal and functioning. When a person becomes sexually aroused, the muscles in the penis undergo certain changes to facilitate an erection. Here is a detailed explanation of what happens to the muscles in the penis during sexual excitation:
1. Smooth Muscles Relaxation:
- Smooth muscles in the walls of blood vessels and cavernous bodies of the penis relax.
- This relaxation is primarily mediated by the release of nitric oxide (NO) in response to sexual stimulation.
- Nitric oxide causes the smooth muscles to relax, leading to vasodilation and increased blood flow to the penis.
2. Corpus Cavernosum Expansion:
- The relaxation of smooth muscles allows the cavernous bodies (corpora cavernosa) of the penis to expand and fill with blood.
- As the cavernous bodies fill with blood, they become engorged and rigid, resulting in an erection.
- The expansion of the corpus cavernosum is essential for maintaining the rigidity of the penis during sexual activity.
3. Corpus Spongiosum Relaxation:
- The corpus spongiosum is another erectile tissue in the penis that surrounds the urethra.
- During sexual excitation, the smooth muscles in the corpus spongiosum also relax.
- This relaxation allows the corpus spongiosum to fill with blood, helping to maintain the rigidity of the penis and ensure the uninterrupted flow of semen through the urethra during ejaculation.
In summary, the muscles in the penis are relaxed during sexual excitation. This relaxation allows for increased blood flow to the penis, leading to an erection and facilitating sexual intercourse.

Answer

Understanding Sexual Excitation in the Penis
During sexual excitation, the physiological changes that occur in the penis are crucial for achieving an erection. Here’s a detailed explanation of why the correct answer is 'A) Relaxed.'
Role of Smooth Muscles
- The penis contains smooth muscle tissue within the corpora cavernosa, which are two columns of erectile tissue.
- During sexual arousal, these smooth muscles relax due to the release of nitric oxide (NO).
Blood Flow Increase
- The relaxation of smooth muscles allows blood vessels to dilate, significantly increasing blood flow to the penis.
- This influx of blood fills the corpora cavernosa, leading to an erection.
Pressure and Rigidity
- As blood fills the erectile tissues, pressure increases, causing the penis to become rigid and erect.
- The relaxation of the muscles is essential, as contracted muscles would restrict blood flow and prevent an erection.
Contrasting Muscle States
- If the muscles were contracted (option B) or collapsed (option C), blood flow would be reduced, and an erection would not occur.
- Therefore, the state of being relaxed is critical for the physiological process of erection.
Conclusion
In summary, during sexual excitation, the smooth muscles in the penis are relaxed, allowing increased blood flow and resulting in an erection. This physiological mechanism is vital for sexual function and reproduction.
