Muscle movement/function

Question 1

Name all the important adductors !

Answer 1

The long head of m. triceps brachii,
The short head of the m. biceps brachii,
Latissimus dorsi,
Pectoralis major,
Teres major,
The clavicular and spinal fibers of the deltoid muscle

Question 2

Name all the abductors of the upper limb

Answer 2

1. Long head of m. biceps brachii
2. The deltoid muscle
3. M. supraspinatus
   (trapezius + serratus m. can help the movement as well)

Question 3

what is the main elevator of the upper limb?

Answer 3

M. serratus anterior, helped by the: m. trapezius + m. pectoralis minor. The movement is dependent on the sternoclavicular + the acromioclavicular joints. This movement is basically a continuation of the previous abduction

Question 4

muscles that perform the anteversion of the upper limb?

Answer 4

those are:

1. The clavicular fibers of the deltoid + some of the fibers of the acromial part,
2. m. biceps brachii
3. m. pectoralis major
4. coracobrachialis
5. serratus anterior muscle

Question 5

The muscles which make the retroversion if the upper arm possible are:

Answer 5

Latissimus dorsi
Long head of the triceps brachii
Teres major
The deltoid

Question 6

Lateral (external rotation) is possible thanks to the

Answer 6

m. infraspinatus (the strongest one)
m. teres minor
spinal part of the deltoid muscle
