The lateral fragment (including the whole upper limb) will be: ⬇️↗️ a. Depressed ⬇️--------------------------------------------- By gravity. (الجاذبية الأرضية) b. Pushed forwards + Medially rotated ↗️----- By the muscles attached to the bicipital groove of the humerus. 2. The medial fragment is elevated ⬆️-------------- By the sternocleidomastoid muscle. 💠💠💠💠💠💠💠💠💠💠 𝐀𝐥𝐰𝐚𝐲𝐬 𝐫𝐞𝐦𝐞𝐦𝐛𝐞𝐫: 👇 1. The clavicle is the first bone to ossify, around the fifth to seventh weeks in utero (Moseley, 1968; Ogata and Uhthoff, 1990). It is also the last bone to fully unite, typically between the 22nd and 25th years (Rockwood et al., 2006; Kim and McKee, 2008). 2. Intramembranous ossification directly converts the mesenchymal tissue to bone, forming the flat bones of the skull, clavicle, and most cranial bones. 💠💠💠💠💠💠💠💠💠💠 𝐌𝐂𝐐: 🤔💪 👋 1. ًWhich muscle is attached to the inferior surface of the clavicle?
