GENERAL HISTOLOGY

Detailed explanation-1: -The main muscles that shoulder shrugs target are the trapezius muscles. These muscles are located on either side of your neck. They control the movement of your shoulder blades as well as your upper back and neck.

Detailed explanation-2: -Like most resistance training exercises, the shoulder shrug will help you build more strength. The upward pulling motion of the shrug contracts the traps, which relax again once the weight is lowered. The shrug fully activates the upper traps, as well as the shoulders which can build a full and strong physique.

Detailed explanation-3: -Dumbbell shrugs, also known as dumbbell shoulder shrugs, are an isolation exercise targeting your upper trapezius muscles. Perform dumbbell shrugs by grabbing a pair of dumbbells and holding them by your sides with a neutral grip. Keep your arms straight as you lift your shoulders toward your ears.

Detailed explanation-4: -The trapezius muscle controls the action of shrugging the shoulders, and the sternocleidomastoid the action of turning the head. Like most muscles, control of the trapezius muscle arises from the opposite side of the brain. Contraction of the upper part of the trapezius muscle elevates the scapula.
