- Panniculus carnosus
The panniculus carnosus is part of the
subcutaneous tissue. It consists of sheets of flat muscle contained in thepanniculus adiposus . The general arrangement is that one end of the muscle sheet is attached toskin 'sdermis and the other is attached to deepfascia orbone . It therefore moves, wrinkles or dimples the skin.Its degree of development varies in different animals. In domestic quadrupeds such as horses and cattle it is evenly distributed over the body wall, and can be seen in action when these animals twitch their skin to discourage flying insects.
In
human s, the panniculus carnosus is highly developed and specialised, primarily to form muscles of thescalp andface . It is also present in other areas of the body wall.Muscles of the panniculus carnosus
