The following sections provide a basic framework for the understanding of gross human muscular anatomy, with descriptions of the large muscle groups and their actions. The various muscle groups work in a coordinated fashion to control the movements of the human body.
The muscle and skeletal systems, for example, act together to move the body. The skeletal system also protectively houses internal organs, such as the brain, heart, and lungs, while the muscle system aids in breathing and interacts with the nervous system to coordinate sensory and muscle responses.
The nine major organ systems in the human body are the integumentary system, the musculoskeletal system, the respiratory system, the circulatory system, the digestive system, the excretory system, the nervous system, the endocrine system, and the reproductive system.
Human muscle system - Abdominal Muscles, Anatomy, Function: There are three muscular layers of the abdominal wall, with a fourth layer in the middle anterior region. The fourth layer in the midregion is the rectus abdominis, which has vertically running muscle fibres that flex the trunk and stabilize the pelvis.
Human muscle system - Evolution, Anatomy, Function: The arrangement of striated muscle in modern humans conforms to the basic plan seen in all pronograde quadrupedal vertebrates and mammals (that is, all vertebrates and mammals that assume a horizontal and four-legged posture).
The human body contains 11 major organ systems: immune, digestive, endocrine, nervous, urinary, cardiovascular, lymphatic, respiratory, integumentary (skin), muscular, and skeletal. Each system includes one or more organs or structures that work together to maintain a given function.
Human muscle system - Shoulder Muscles, Joints, Movements: The shoulder is a complex ball-and-socket joint comprising the head of the humerus, the clavicle (collarbone), and the scapula. The shoulder’s main motions are flexion, extension, abduction, adduction, internal rotation, and external rotation. Shoulder flexion is movement of the ...
human skeleton, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue—the ligaments and the tendons—in intimate relationship with the parts of the skeleton.

Scientists find it useful to divide the human body into 11 major systems: skeletal, muscular, circulatory, respiratory, digestive, urinary (excretory), endocrine, nervous, integumentary, reproductive, and immune. The principal parts of each of these systems are described and illustrated in this article.
