Corrugator Supercilii Muscle
The corrugator supercilii muscle is a small, narrow, pyramidal muscle of the face. It arises from the medial end of the superciliary arch; it inserts into the deep surface of the skin of the eyebrow. It draws the eyebrow downward and medially, producing the vertical "frowning" wrinkles of the forehead. It may be thought as the principal muscle in the facial expression of suffering. It also shields the eyes from strong sunlight. Structure The corrugator supercilii muscle is located at the medial end of the eyebrow. Its fibers pass laterally and somewhat superiorly from its origin to its insertion. Origin It arises from bone at the medial extremity of the superciliary arch. Insertion It inserts between the palpebral and orbital portions of the orbicularis oculi muscle. It inserts into the deep surface of the skin of the eyebrow, above the middle of the orbital arch. Innervation Motor innervation is provided by the temporal branches of facial nerve (CN VII). Vasculatu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corrugator Cutis Ani Muscle
The corrugator cutis ani is a muscle of the human body, also known as the Ellis' muscle, after the anatomist George Viner Ellis. Around the anus is a thin stratum of involuntary muscle fiber, which radiates from the orifice. Medially the fibers fade off into the submucous tissue, while laterally they blend with the true skin Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other animal coverings, such as the arthropod exoskeleton, have different .... By its contraction it raises the skin into ridges around the margin of the anus. The name of this muscle is primarily limited to older texts. External links * References Muscles of the torso {{muscle-stub ...

Corrugated Fiberboard
Corrugated fiberboard, corrugated cardboard, or corrugated is a type of packaging material consisting of a fluted corrugated sheet and one or two flat linerboards. It is made on "flute lamination machines" or "corrugators" and is used for making corrugated boxes. The corrugated medium sheet and the linerboard(s) are made of kraft containerboard, a paperboard material usually over thick. History Corrugated (also called pleated) paper was patented in England in 1856, and used as a liner for tall hats, but corrugated boxboard was not patented and used as a shipping material until 20 December 1871. The patent was issued to Albert Jones of New York City for single-sided (single-face) corrugated board. Jones used the corrugated board for wrapping bottles and glass lantern chimneys. The first machine for producing large quantities of corrugated board was built in 1874 by G. Smyth, and in the same year Oliver Long improved upon Jones' design by inventing corrugated board with lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
