7 biceps: striated

8 trapezius: striated

9 stomach: smooth

10 gastrocnemius: striated

Explanation:

Striated muscle is a type of tissue composed of repeated functional units called sarcomeres, which are the basic contractile unit of the muscle fiber. The striated appearance is caused by repeating bands of actin and myosin proteins. Striated muscle tissue is subdivided into two major parts: 1-cardiac muscle and 2-skeletal muscle. Skeletal muscle is a highly dynamic tissue that is mostly attached by tendons to the bones in the skeleton. This voluntary tissue (skeletal muscle tissue) is composed of multiple fascicles or bundles of muscle fibers. Moreover, cardiac muscle tissue, also known as myocardium, is a type of striated muscle that contracts and releases involuntarily, composed of cells called myocytes present in the heart. Finally, smooth muscle is a type of involuntary and non-striated muscle tissue localized within the walls of organs/structures (i.e., intestine, esophagus, stomach, uterus, urethra, bladder, blood vessels, etc.).
