The antagonist of teres minor is:
To medial rotation: latissimus dorsi, long head of triceps, pectoralis major, subscapularis.
In Extension of humerus: latissimus dorsi, posterior deltoid and long head of triceps
There are more than one: The deltoid, supraspinatus, infraspinatus, teres major and minor and the subscapularis.
Anterior deltoid
i believe its tibialis anterior
It is the middle deltoidIt is the Deltoid Muscle .
Serratis anterior
The deltoid muscle is the big muscle on the shoulder. It has three parts; the front or anterior, middle and back or posterior. It involves the shoulder joint.
The primary agonist muscle in a lateral dumbbell raise is the deltoid, specifically the lateral (side) head of the deltoid. The antagonist muscle is the latissimus dorsi, which performs the opposite movement by extending the shoulder while the deltoid is lifting the dumbbell.
Tibialis anterior
The deltoid muscle looks like a large "D" covering the shoulder. There are three parts to it: The anterior deltoid which is commonly called front delts, The lateral deltoids or side delts, and the posterior deltoid or rear delts. The anterior deltoid's (front delts') origin is the clavicle, the lateral's (side delts') origin is the acromion process of the scapula and the posterior's (rear delts') origin is the spine of the scapula. The insertion for all is the deltoid tuberosity on the humerus.
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.
the supraspinatus ...I think Deltoid muscle(acromial part)
The antagonist to the gastroc and soleus muscles is a combination of muscles, primarily the tibialis anterior and fibularis (peroneus) tertius.
