What muscles can flex the forelimb?
corabrachialis, biceps brachii, deltoid, pectoralis major
Identify the upper limb muscles used to play the cymbals in a band?
pectoralis major, biceps brachii, deltoid
What muscles involved in shoulder joint adduction act as fixators?
The muscles that perform adduction to the shoulder include the pectoralis major, lattissimus dors, but these are the primary movers. The fixators that do adduction are the subscapularis and teres major.
What muscles abducts the humerus?
The major muscle that abducts the humerus is the Deltoid. (all muscles move in conjuction, there may be more muscles that contribute to the abduction of the humerus) pectoralis major and latissimus dorsi
What abducts the humerus?
The major muscle that abducts the humerus is the Deltoid. (all muscles move in conjuction, there may be more muscles that contribute to the abduction of the humerus) pectoralis major and latissimus dorsi
What are the antagonist in a seated row?
The primary antagonist muscles in a seated row are the pectoralis major, anterior deltoid, and biceps brachii. These muscles lengthen as the back muscles contract during the rowing motion.
Which of the muscle is the largest chest muscle?
shoulder: deltoid. Chest: Pectoralis major
Which muscle abducts the shoulder?
The middle part of the deltoid abducts the shoulder, as well as shoulder abduction at the supraspinatus and biceps brachii muscles.
What muscles cause horizontal adduction in the shoulder?
The major muscles involved in horizontal adduction or flexion is the anterior deltoid fibres, pectoralis major and minor. Bicep complex(bbicep brachii, brachioradialis and forearm flexor) comes into action as synergists, if the leverage is long.The antagonists of horizontal flexion is posterior deltoid fibres,teres major, minor, lats and the associated rotator cuff muscle(infraspinatus)
