Comprised of skeletal, visceral, and cardiac muscle tissue. There are more than 600 muscles in the human body.
The muscles in the body, usually applied only to striated muscles.
The more than 600 muscles that are attached to and supported by the bones of the skeleton. These muscles shorten or lengthen to move the bones to which they are attached. These movements are voluntary, or under conscious control. Together, the muscles and bones form the moving framework of the body referred to as the musculoskeletal system.
The system that includes the skeletal muscles and their tendons.
Body system that covers, shapes, and holds the skeleton system in place; muscular system contracts and moves various parts of the body.
The muscles connected to the skeleton enable voluntary movement and provide support and stability to the bones. Typically, a muscle is attached to one bone, often through a tendon, and extends across a joint to connect to another bone.
Muscles create motion by contracting and pulling on the bones they’re connected to. They are designed to pull but not push, so they are often paired with other muscles or muscle groups to counteract or reverse a movement. While the actions of skeletal muscles are mostly consciously controlled, they can also perform reflex actions in reaction to specific triggers.
The body has over 600 muscles, grouped by the kind of motion they facilitate. Extensors expand a joint while flexors contract it. Adductors pull a body part inward, while abductors push it outward. Levators lift a part, and depressors bring it down. Meanwhile, constrictor or sphincter muscles encircle and seal openings.
