What is the primary function of striated muscle?

The primary function of striated muscle is movement of the body. Striated muscles, which include skeletal muscles, are characterized by their banded appearance and are responsible for voluntary movements. These muscles are attached to bones and work in pairs to produce movement through contraction and relaxation. When a muscle contracts, it pulls on the associated bone, resulting in motion. This function is essential for everyday activities such as walking, running, lifting, and any other physical activity that involves voluntary movement.

While striated muscles can also support the body by maintaining posture and stability during movement, their main role is to enable motion. Other functions related to muscle tissue include aiding in the circulation of blood (in the case of cardiac muscle, which is also striated but involuntary) and generating heat, but when considering the primary purpose, facilitating movement is the most significant aspect.
