The body contains over 650 different muscles…
Skeletal muscle is composed of striated tissue that can actually shorten or contract pulling the bone to which they are attached, thus causing movement…
Muscle is attached to bone by fibrous connective tissue called tendons…
Tendons are attached to the outer "skin" of the bone called pereostem…
Muscles usually work in groups…
Each muscle is made up of thousands and thousands of individual cells called muscle fiber.
while the number of muscle cells/fibers do not increase, each individual muscle fiber has the potential to increase in size density and efficiency.
FUNCTIONS OF MUSCULAR SYSTEM
Producing Movement: Just about all movements of the human body and its parts are a result of muscle contraction. Skeletal muscles are responsible for all locomotion and manipulation.
Maintaining Posture: Muscle functions almost continuously, making one tiny adjustment after another that enables us to maintain an erect posture despite the never ending downward pull of gravity.
Stabilizing Joints: They stabilize and strengthen the joints of the skeleton.
Generating Heat: Muscles generate heat as they contract. This heat is vitally important is maintaining normal body temperature.
