Time room high tide response (figure)

The Breast is the female mature important symbol,is one of feminine most important nature sensitive areas,also secretes the milk,nurtures the descendant the organ. The breast to the child is the maternal symbol; To the male is the object which beautiful and thirsty (wants) to look. Therefore at the movie,the television,the pictorial,in the literary work female always has the plentiful breast. The breast to the female is the important reproductive organ,it is also playing in the natural activity the vital role,but the people have often neglected this point. The breast innervation and nerve ending quantity is very rich,the breast and other reproductive organ relations are extremely close.

In the natural response cycle excitation period,the breast the first evidence which strengthens to the natural intense response is the nipple erection responded that,this is in the nipple the rich smooth muscle fiber after receives the stimulation to have the dependent contraction result.Two nipple responses are not frequently the synchronization appear,a possibility already achieved erects completely and swelling,but another appears the hysteresis actually. In falls the nipple possibly instead protrudes by theirs repose period condition,probably is in half erection position,if in this kind falls is restores with difficulty,that could not see the nipple the response referred drafts.

Before the full erection response may cause the nipple length compared to not to stimulate has the increase,increases 0.5-1.0 centimeter generally,responded also may make the nipple basis diameter to increase 0.25-0.5 centimeter. Usually the nipple big and forward prominent often has the small tumescent erection tendency compared to the size normalcy. The nipple is specially small when very is also difficult to the natural stimulation to make the very strong response,but the nipple specially small situation not much sees.

The excitation period second physiological change is the breast vein tree pattern delimitation and the expansion increase.If the breast has the enough volume underneath,can appear the table shallow vein hyperemia,but very possible to have to arrive the excited later period only then to become more explicit. The big breast usually displays the very obvious vein tree pattern the expansion. Breast vein tree's hyperemia to central expansion when usually does not achieve the areola area.

Is approaching the platform time,the breast actual volume can increase obviously,this is the breast depth portion vein hyperemia response result. Is at the reactive state woman occurs when the erection response,lower part the mastoptosis hyperemia changes in observes,if the bride's side takes time the supine decubitus,the breast volume comprehensive increase will be more obvious. Arrives the obvious areola hyperemia phenomenon obviously in the excited later period. The excitation period responded the performance degree and has the time difference to be very big,because because often human from time to time different. The close neighbor erects the nipple areola in the platform time also to be able to be tumescent,by now frequently caused man-made to become one kind of illusion,probably erected the nipple already the part abated.Until areola swelling after retrogression time retrogression,the people only then might see the retrogression lately still the maintenance erection nipple.

Experiences before the final high tide impulse in the female,has not nursed the feminine breast size may compared to usually increase 1/5-1/4,has nursed the feminine breast usually cannot appear the breast volume the obvious increase. In this anatomy displays the difference possibly is because feeds the milk breast to have the increase in the milk production process median vein divergence. The baby sucks can increase the vein the divergence,and tends to causes the natural tense time in-depth blood vessel the hyperemia response slow-down. Very obvious,not only under natural intense influence breast size increase with blood vessel hyperemia physiological reaction related,but also plays the support role fiber structure ingredient substantial degree with the composition breast small leaf to concern. Expands excessively in the nursing early time common breast,this can damage these support fiber structure the validity. Therefore,after may understand nursing the feminine breast with difficulty makes the obvious natural response to the natural stimulation which should have.
