Machende ndiwo gondolas (genital gland) murume. Iwo anowanikwa pazasi uye pamativi ese emboro. Iwo anobatwa panzvimbo nesaga rinotsemuka rakaita seganda uye mamwe mashoma mashoma kuti ridzivirire. Tsandanyama Ndiyo imwe yezvikamu zvinoita kuti bhegi rinenge raumbwa rakakwinyana, richisiya machende akanyanya kugadzikana kana kuunganidzwa.
Matumbu aya ndivo vanogadzira urume uye mahomoni epabonde kusanganisira iyo testosterone. Pasina kupokana tiri kutaura nezvenhengo dzegonhi dzakati kurei mukuenzana neicho chiri gadziriro yokubereka nayo yechirume.
Machende akaita sei?
Nhengo idzi ane oval shape nehukuru huri pakati pemasendimita mana kusvika masere pakureba uye masendimita maviri kana matatu paupamhi. Vakakomberedzwa ne bhegi reganda rinonzi scrotumIyo yakaoma kwazvo uye yakanyatso elastic, iyo ichaita kuti tembiricha yayo irambe yakadzikira pane iyo yese yemuviri, pakati pe1 kusvika 3 ° zvishoma. Chitarisiko chayo, vhudzi kana ruvara zvinoenderana nezvakawanda kubva kumurume kuenda kune mumwe zvakapihwa dzinza rake kana zera.
Munhu, semune dzimwe mhuka dzinoyamwisa, dzine machende ayo kubva mudumbu chikamu, kurudyi nekuruboshwe kwe lumbar spine uye pedyo neitsvo. Pakuzvara kwaamai, mwana wechirume anomera machende mudumbu, asi anosiya dunhu iri kudzika kunzvimbo yezvidya, achizvuzvurudza nawo mabhegi akaipoteredza uye achidzokorora chimiro chekupedzisira.
Machende dzakatsvuka kana bhuruu-chena muruvara, zvese zvinoenderana nekuti urikugezesa sei ropa rako. Zvakajairika kuwana madiki emafuta cysts pazera rekukura uye kwete paudiki, angiomas inoratidzika sekuda, varicose tsinga, kunyangwe vese vasina kuudza chero rudzi rwedambudziko rakakura.
Scrotal region
Ndiyo nzvimbo yese inovhara kana kutenderedza machende, Akaita saga uye akareba. Inowanikwa pasi pe pubic area, pamberi peperineum uye kuseri kwepeni. Iyi nharaunda yese yakakamurwa kuita zvidimbu zvinoverengeka:
- Ganda kana scrotum: ndiyo chikamu chakanakisisa uye chokunze, panokura bvudzi.
- Darts: Iro ndiro rinoramba richienda kune scrotum, zvakare rakatetepa uye rinoumbwa neakatsetseka mhasuru fibers.
- Seros tunic kana Cooper's fascia: ine anatomy yakafanana nefibers dzinobva kune yakakura oblique tsandanyama yedumbu. Mafiibha aya anodhonzwa nemachende kuti adzike kubva mudumbu akananga kuscrotal area.
- Muscular tunic: Iyo inoumbwa nekuwedzera kweiyo cremaster muscle, iyo inoperekedza spermatic cord. Fiber dzayo dzinobva mumhasuru dzemhasuru dzemhasuru dzakafara dzedumbu dzinokweverawo kudzika pasi pechende.
- Fibrous tunic: Yakaumbwa sesaga uye inotenderedza nzvimbo yespermatic cord uye testicle.
- Vaginal tunic: is a serous membrane inopeta mukati me testicle uye epididymis
Mufananidzo wakatorwa kubva kuWikipedia neGoogle Sites. Testicle, epididymis and spermatic funiculus of a domestic cat: 1. Front, 2. Rear, 3. Edge of the epididymis, 4. Outer edge, 5. Testicular mesentery, 6 Epididymis, 7. Network of arteries and veins of the testicle, 8. Vas deferens.
Bumbiro rechende mukati
The testicle uye epididymis dzakaumbwa nezvikamu zviviri zvakasiyana zvikuru. Chimwe chikamu chinonzi fibrous kana albuginea chinovhara chinonzi 'testicular albuginea' uye ndiyo inofukidza chibereko. Uye pane 'epididymal albuginea' kuvhara epididymis.
The testicular albuginea Inhengo ine fibrous yakanyanya yakatenderedza testicle, iyo yekunze yakaumbwa ne 'visceral leaflet' yehembe yemukadzi. Uye chikamu chayo chemukati chinoenderana nenyama ye testicle pachayo.
Muchikamu chekupedzisira chepamusoro muganhu ndeye iyo 'Highmore body' panoitwa network yesperm ductules inonzi 'Haller's network'. Nhevedzano yelamellae kana septum inotanga kubva kune imwe yezvikamu zveHighmore iyo inokura yakananga kunharaunda yetesticle, ichikamura kuita lobules.
Testicles inoshanda
Basa rechende kunyanya nderokuti kugadzira nekuchengeta urume, asi ngatitarisei zvakanyanya pane zvimwe zvaanogona kugadzira:
- Kugadzirwa kwesperm: Iyo seminiferous tubules inogadzirwa, muchikamu chekunze chemadziro etubules, uko masero. Masero aya anoita denderedzwa rekutanga uye anozorebeswa, zvekuti anozopedzisira ave urume hwakura. Kubva pano vanozopfuura nemumachubhu kushambira vakananga kune epidymis, vas deferens uye seminal vesicles, kwavanozopedzisira vachengetwa.
- Testosterone kugadzirwa: Inowanikwa mune inopindirana tishu iyo panguva imwechete inogara pakati petubules, nzvimbo yakapfuma mumasero eLeydig ane basa rekugadzira. testosterone. Iyi hormone ichagoverwa mumuviri wose kuburikidza neropa kuitira kuti iite mabasa ayo. Kana testosterone inodonha nemukana, inogona kunge yakakonzerwa nekuti machende ari madiki kubva pakuzvarwa (testicular atrophy), kana nekuti testicular tishu yakarasika, kana nekuda kwekupinda kwemurume kuenda kumwedzi kana kushandiswa zvisina kunaka kwevanabolic steroid. .
