The muscle that inserts on the acromion and scapular spine is the Trapezius.
The trapezius muscle inserts into the scapular spine acromion and posterior superior lateral clavicle. Contraction of its various parts thus allows the scapula to be lifted, suspended, stabilized, and rotated. inserted. The deltoid muscle inserts into the acromion process, the main muscle that raises and extends the arm.
In humans, the acromion process can be flat curved hooked, or convex depending on the shape. The intrinsic muscles of the scapula include the rotator cuff teres major subscapularis teres minor and infraspinatus. These muscles attach to the surface of the scapula and assist in the abduction and external and internal rotation of the glenohumeral joint.

Answer:
The plus end for all actin filaments.(Ans. A)
Explanation:
All three types of muscles (cardiac, smooth, and skeletal) utilize actin filaments to generate force which leads to cell contraction. Actin filaments is organized into sarcomeres which function as the fundamental unit of contraction.
Sarcomeres are approx 2.4 micro meter in length, and they are bounded at both end with the help of Z-disks. Plus end of the Z-disks are oriented with actin filaments and their minus ends to the direction of center of the sarcomeres. Z-disk consist an actin capping protein, which is known as cap-Z. Cap-Z helps to bind plus end of the actin filaments.
