Orqaning serbar muskuli Kurakni ko‘taruvchi muskul

Ko‘krakning kichik muskuli (m. pectoralis minor) ko‘krakning katta muskuli ostida yotadi. II–V qovurg‘alardan boshlanib, kurakning tumshuqsimon o‘sig‘i (processus coracoideus)ga yopishadi.
F u n k s i y a s i. Muskul qisqarib yelka kamarini pastga tortsa, qo‘l qimirlamay turganda qovurg‘alarni ko‘tarib, ko‘krak qafasini kengaytiradi, nafas olishga yordamlashadi. I n n e r v a t s i y a s i: nn. pectorales medialis et lateralis (C_VII–th_I)dan.
Q o n t o m i r l a r i: a. thoracoacromialis.
O‘mrov osti muskuli (m. subclavius) o‘mrov suyagidan boshlanib I qovurg‘aga yopishadi.
F u n k s i y a s i. O‘mrov suyagini pastga tortadi.
I n n e r v a t s i y a s i: n. subclavius dan.
Q o n t o m i r l a r i: a. transversa scapulae, a. thoracoacromialis.
Oldingi tishli muskul (m. serratus anterior) keng, to‘rt qirrali muskul, yuqori qovurg‘alarning 8 va 9 tasidan alohida tishlar (bo‘laklar) shaklida boshlanib, kurakning medial chetiga yopishadi.
F u n k s i y a s i. Muskul qisqarib kurakning pastki burchagini oldinga buradi va qo‘lni yuqoriga ko‘taradi. Qo‘l qimirlamay turganda qovurg‘alar ko‘tarilib, nafas olish yengillashadi.
I n n e r v a t s i y a s i: n. thoracicus longus (C_V–_VIII)dan.
Q o n t o m i r l a r i: a. thoracodorsalis, a. thoracica lateralis, aa. Intercoctales posteriores.
