This video explains the anatomy
This video explains the anatomy of the scapular region, including the deltoid muscle, subdeltoid bursa (subacromial), deltopectoral groove, axillary nerve, shoulder extension, serratus anterior muscle, and intermuscular spaces. (including MCQ, practical, and interactive questions).

- What are the 𝗮𝗰𝘁𝗶𝗼𝗻𝘀 of the muscles that act on the shoulder? 🤷♂️🤷♀️
𝒜𝓃𝓈𝓌𝑒𝓇: ⇊
1. Deltoid
- Anterior fibers ----- Flexion + Medial rotation.
- Middle fibers ------- Abduction from 18º to 90º.
- Posterior fibers ---- Extension + Lateral rotation.
(deltoid produces 𝐀𝐋𝐋 movements of the shoulder joint 𝑬𝑿𝑪𝑬𝑷𝑻 adduction)
2. Subscapularis - Adduction and medial rotation of the shoulder.
3. Supraspinatus - Abduction (0º – 18º)
4. Infraspinatus - Lateral rotation.
5. Teres minor - Lateral rotation + Adduction.
6. Teres major - Medial rotation + Adduction + Extension.
7. Serratus anterior - Protraction of the scapula (forward movement of the scapula).
- The lower fibers of the serratus anterior + upper fibers of the trapezius rotate the scapula to produce abduction 𝟗𝟎º 𝐭𝐨 𝟏𝟖𝟎º (to elevate the arm above the head).
* 𝐌𝐂𝐐: 💪
1. Paralysis of the deltoid muscle results in which of the following?
A. Loss of abduction of the arm from zero to 18°
B. Loss of abduction of the arm from 18° – 90°
C. Loss of abduction of the arm from zero to 90°
D. Loss of abduction of the arm from 90° – 180°
2. A patient injured the muscle that is an antagonist (has an opposing action) to the serratus anterior muscle, which is the primary protractor of the scapula. Which muscle is injured?
A. Levator scapula
B. Rhomboid major
C. Pectoralis minor
D. Supraspinatus
3. The root value of the axillary nerve is which of the following?
A. C. 5,6,7,8 & T. 1
B. C. 5,6,7
C. C. 5,6
D. C. 5
4. Which nerve is probably damaged if a patient can’t abduct the arm up to 900?
A. Axillary
B. Radial
C. Musculocutaneous
D. Median
5. Which of the following nerves gives a motor supply to the deltoid muscle?
A. Axillary nerve
B. Ulnar nerve
C. Musculocutaneous nerve
D. Radial nerve
