Elka chigali (plexus brachialis) — bu yuqori qo‘lning motor va sezuvchi innervatsiyasini ta’minlovchi nerv tolalarining murakkab tarmog‘idir.Abstract
Ushbu maqolada elka chigali (plexus brachialis)ning anatomik tuzilishi, uning qisqa va uzun shoxlari, shuningdek qo‘l terisining innervatsiyasi haqida ma’lumot berilgan. Elka chigali bo‘yin nervlarining (C5–C8) va birinchi ko‘krak nervining (Th1) oldingi shoxlaridan hosil bo‘lib, qo‘lning barcha mushaklari va terisini nerv tolalari bilan ta’minlaydi.Qisqa shoxlar asosan elka va kurak mushaklarini innervatsiya qiladi, ular orasida nervus dorsalis scapulae, nervus suprascapularis va nervus thoracicus longus kabi nervlar muhim o‘rin tutadi. Uzun shoxlar esa nervus musculocutaneus, medianus, ulnaris, radialis va axillaris kabi nervlar orqali qo‘l va bilak mushaklariga hamda terisiga sezuvchi va harakatlantiruvchi impulslar yetkazadi.
