Why does the testes pull closer to the body when hitting cold water?
cause your body cells come close to each other
Why is it important for the testes be outside the body?
Sperm production requires an environment that is neither too hot or too cold. The cremaster muscles are those that will raise or lower the scrotal sac. If the testes are too warm, the cremaster muscles loosen and the scrotal sac will hand lower. If the testes are too cold, the cremaster muscles will control and draw them up closer to the body for warmth. So it's all about temperature control.
How do the scrotal muscles help maintain temperature homeostasis of the testes?
This is an interesting question. Sperm do best at temperatures slightly below the temperature of the body. This is why the testes are located outside of the abdomen. The scrotal muscles tense and relax to control the distance of the testes from the body. If it is colder they will pull the testes closer to take advantage of body heat. If it gets hotter they will relax to allow the testes to get further from the warmth of the body. Hope this helps! (BTW, they also have a reflexive action that pulls the testes close to the body when something touches the inner thigh. This does nothing to maintain a constant temperature but it does help protect them from injury.)
Why must the testes be outside of the abdominal cavity?
The temperature needed for the sperms to survive and thrive is lower than the optimum body temperature , hence it is not possible to maintain a lower temperature inside the body hence the testes are located outside the body.
How can a tendon pull a bone?
When it contracts
When you close the lid and your laptop goes to sleep How does the laptop know the lid was closed?
well you see the computer has a magnet that has a cable that contracts when you pull it (pull it = close the computer ) it make the computer automatically say oh time to go to sleep either that or the technology is really cool these days. Haha! :)
Which part of the arm contracts to pull up the lower arm?
the musle at the front of your upper arm contracts to pull up your lower arm
Can an F5 tornado pull the flesh from off the human body?
No, because there really isn't a way to "pull" it from your body. They can actually scour grass and pavement off the ground, but if you were that close to one chances are you'd just be thrown through the air.
What is a slit mehod of castrating piglet and kids?
A knife is used to make a slit in the scrotal sac to squeeze out and expose the testicles, which enable being able to crimp or cut the spermatic cord attached to the testes, or pull the testes out.
How far do your balls drop?
It varies from boy to boy and also depends on the temperature and the state of sexual arousal. The testes produce sperm better at a slightly lower temperature than the rest of the body so if it is warm the scrotum will tend to hang lower to keep the testes further away from the heat of the body. Colder temperatures and an erection tend to pull the scrotum closer to the body.
How does a figure skater spin fast?
pull arms close to your bodykeep a 'secure' position (don't make your body 'loose')skate faster into the spinpractice
What do rabbit testes look like?
In between your rabbits back legs you will see 2 ball-shaped protuberances that have no fur on them: these are the testes. Sometimes they are hidden behind fur. Actually, these are the scrotums: the testes are inside the scrotums, and you can't actually see them. Keep in mind that rabbits can draw their testes up into the body cavity so they are not always visible. This is an adaption that helps prevent injury while digging/fighting/running etc. Especially when a rabbit is frightened, he will pull his testes into his abdomen. You may still be able to locate the scrotums, but when they're empty they can be hard to find. Also, baby rabbits are born with the testes in their abdomen, and they don't descend into the scrotums until they grow a little older (around 4 months of age, they are usually descended, but it can take up to 5 months).
