YELKA MUSKULLARI

Yelka muskullari uzun muskullardan iborat bo‘lib, joylashishiga ko‘ra old va orqa guruhlarga ajratiladi.

Yelkaning oldingi tomonidagi muskullar. 49, 50-rasmlar Yelkaning ikki boshli muskuli (m. biceps brachii) teri ostida yaqqol ko‘rinadi. Uning uzun boshi (caput longum) kurak suyagi bo‘g‘im yuzasi tepasidagi g‘adir-budur (tuberculum

Bilak g‘adir-buduri bilan muskul payi oralig‘ida – bursa bicipitoradialis joylashgan.
