Answer:
Coracobrachialis muscle.
Step-by-step explanation:
Coracobrachialis muscle is attached with the scapula through the coracoid process. This is the smallest of the three muscles that are involved in the coracoid process.
The corachobrachialis muscle helps in the flexion of the arm. This muscle also adducts the arm at shoulder point along with the pectoralis major muscle. This muscle helps in the internal rotation of the shoulder.
