Nhazi nke larynx mmadụ

Nkọwa na ebe anatomical

Larynx bụ akụkụ nke ikuku nke nwere ihe olu ma jikọta pharynx na trachea. Nkọlọ udọ jikọọ na hyoid ọkpụkpụ na bụ iwepụ na 4, 5 na nke 6 cervical vertebrae si n'ihu n'akụkụ nke n'olu. Ọ bụ a oghere ahụ kpụrụ nke ụdọ, cartilage na skeletal muscle. Ọdịdị nke ogwooro na-enye ohere iji nwalee onye akụkụ ahụ, dị ka ndị ikom na ndị inyom na Adam apple cricoid. N'akuku ya, enwere ọnụ ụzọ nke oghere, lee larynx jikọtara na pharynx, na mpaghara ala ọ na-agafe na trachea. Na-esote larynx bụ akwara ụbụrụ na-arịa ọrịa vascular, na n'akụkụ ọ bụla nke ya bụ ụrọ thyroid gland. N'anụ ahụ, akụkụ a dị ezigbo mkpa, n'ihi na larynx na-emepụta olu. Ọ bụkwa ebe a na-ebugharị maka ikuku n'ime akpa ume.

Akpu cartilaginous

Nhazi nke larynx gụnyere ọtụtụ ụdị na ụdị cartilage. Akpụkpụ cartilaginous, nke bụ ọkpọ ya, nwere ọtụtụ cartilages mobile, nke njikọta njikọta, akpụkpọ anụ na njikọta njikọta. Ọdịdị nke larynx gụnyere ọnụọgụ abụọ (obere) na ihe a na-adịghị akwụ ụgwọ (nnukwu) cartilages.

A na-akpọ cartilage a na-akwụghị ụgwọ a na-akpọ thyroid. O nwere efere abụọ nwere anọ jikọtara n'otu akụkụ, nke dị 45 Celsius maka ụmụ nwoke na 120 Celsius maka ụmụ nwanyị. Abụọ abụọ nke mpi elu na mpi ala site na azụ n'akụkụ nke efere ndị a. Akụkụ bụ isi nke larynx bụ cartilage cricoid, na-eche ihu na arc, na azụ na efere. Akụkụ nke ala nke akụrụngwa a jikọtara ya na mgbanaka mbụ nke trachea. Na nkwonkwo abụọ nke abụọ, a na-ejikọta cartilage cricoid na arytenoid na thyroid cartilages.

Ọdịdị ọzọ nke larynx mmadụ na-aga n'ihu na-arụ ọrụ carrolage. Ọ dị obere na nha ma dị na n'elu cartilage arytenoid. Ebubo a na-ejikọta ọnụ osisi na-enweghị ihe ọ bụla na-adịgide adịgide, ọ na-abụkarị na ọnọdụ na-adịghị mma. A na-ekpuchi larynx site na epiglottis n'elu, ma, n'aka nke ya, ejikọtara ya na sublingual-epiglottis na ligaments shchitoadagortan, nakwa na ị na-eme ka cartilage gị.

Njikọ nke larynx na mmeputakwa ụda

A na-ewere ụdị cartilage ndị yiri nke a na-ahụ anya dị ka ihe ndabere nke larynx. Maka ubughari nke uro ogwu etu na nkwonkwo abuo bu oru:

1. Ejikọtara nkwonkwo arthritic, ọ na-ejikọta akụkụ ndị dị n'akụkụ akụkụ nke cimento cricoid na akụkụ ala nke cartilage thyroid. Ogo nke nkwonkwo a na-apụta na ọdịda ihu, n'oge a na mgbagha nke akwara ahụ cartilage thyroid na-aga n'ihu ma laghachi azụ.

2. Ejikọtara nkwonkwo mkpịsị aka aka, ọ na-agụnye ihe ndị a na-ahụ anya na-adabere na efere nke cartilage cricoid ma na-adabere na cartilage arytenoid. Na nkwonkwo a, ụzụ na-adabere na axis axis, ụda olu na ụda olu dị iche iche na-agagharị ma na-abịarịtara ibe ha, si otú a na-agbasawanye ma na-emechi ọnụ ụzọ nke ụzọ.

Ngwa olu

E mere ndokwa nke larynx na pharynx ka ha wee nwee ngwá olu, ihe dị ezigbo mkpa maka mmadụ. The akwara ụda olu na-mmasị ka arytenoid na thyroid cartilage. N'oge mgbochi nke akwara akpịrị, ọdịdị nke glottis na ogo nke nrụgide nke ligaments gbanwere. N'oge inhalation emee ihe vibration nke akwara ụda olu, si otú, na-guzobere ụdaume. Consonants nwetara na òkè nke egbugbere ọnụ, ire na okpo ọnụ, nkọlọ kamakwa pụrụ isonye na guzobere "na-elo" consonants. Ọtụtụ n'ime ụda ahụ, dị iche na primates, otu nwoke na-ekwu banyere iwepụ.
