Good afternoon!! I have a problem: I quickly come at sexual intercourse (without a condom) literally one-two motions. What it can be?
This condition is called premature ejaculation. For your age, it is normal. Good luck!
On this wall there is an oval aperture - the window of a vestibule closed by the basis of a stirrup; a little above on this wall there is a prominence of the facial channel, and more low - the window of a cochlea closed by a secondary tympanic membrane which separates a drum-type cavity from a drum-type ladder; 4) back mastoid - separates a drum-type cavity from a mastoid and has an aperture which conducts in a mastoid cave, last is in turn bridged to mastoid cells; 5) a lobby somnolent - borders on the somnolent channel.
This fact is widely-known as ways to last longer. Here there is a drum-type aperture of an acoustical pipe through which the drum-type cavity is bridged to a nasopharynx; 6) lateralnuju webby - it is formed by a tympanic membrane and parts of a temporal bone surrounding it. In a drum-type cavity there are three acoustical ossicles covered with a mucosa, and also ligaments and muscles. Acoustical ossicles (149) have fig. the small sizes. Being bridged among themselves, they form a chain which was stretched from a tympanic membrane to an oval aperture. All ossicles are bridged among themselves by means of joints and covered by a mucosa. His supply teacher has a lot more information relative to ways to last longer. The hammer srashchen with a tympanic membrane, and a head by means of a joint is bridged by the handle to an anvil which is in turn movably bridged to a stirrup.
The stirrup basis closes a vestibule window. This thing is well-known as ways to last longer. In a drum-type cavity there are two muscles: one goes from the channel with the same name to the hammer handle, and another - stremennaja a muscle - is referred from a back wall to a back leg of a stirrup. At reduction stremennoj muscles pressure of the basis of a stirrup upon a perilympha changes. The acoustical pipe has on the average length of 35 mm, width of 2 mm, serves for entering of air from a pharynx in a drum-type cavity and supports the pressure identical with external that in a cavity it is very important for normal work zvukoprovodjashchego the apparatus.
The acoustical pipe has cartilaginous and osteal parts, vystlana a ciliary epithelium. The cartilaginous part of an acoustical pipe begins a pharyngeal aperture on a lateral wall of a nasopharynx, is referred downwards and lateralno, then narrowed and forms an isthmus. The osteal part less cartilaginous, lies in the semicanal of a pyramid of a temporal bone with the same name and opens in a drum-type cavity an aperture of an acoustical pipe. Fig. 149.
