Anatomical terms of muscle Anatomical terms of muscle Muscles are described using unique anatomical terminology according to their actions and structure. There are three types of muscle tissue in the human body: skeletal, smooth, and cardiac. Skeletal striated muscle, or "voluntary muscle", primarily joins to bone with tendons. Skeletal muscle enables movement of the bones of the human skeleton and maintains posture. Smooth muscle tissue is found in parts of the body where it conveys action without conscious intent. The majority of this type of muscle tissue is found in the digestive and urinary systems where it acts by propelling forward food, chyme, and
Depressor supercilii muscle Depressor supercilii muscle The depressor Supercilii is an eye muscle of the human body. The nature of this muscle is in some dispute. Few printed anatomies include it (Netter, et al.) and many authorities consider it to be part of the orbicularis oculi muscle. On the other hand, many dermatologists, ophthalmologists and plastic surgeons hold that the depressor supercilii is a distinct muscle and has a definite, individual effect on the movement of the eyebrow and skin of the glabella. The depressor supercilii originates on the medial orbital rim, near the lacrimal bone, and inserts on the medial aspect of
