What does panniculus carnosus meaning?

: a thin sheet of striated muscle lying within or just beneath the superficial fascia, serving to produce local movement of the skin, and well developed in many lower mammals but in humans represented primarily by the platysma.

Which one is an example of panniculus carnosus?

The panniculus carnosus is a part of the subcutaneous tissues in vertebrates. It is a layer of striated muscle deep to the panniculus adiposus. In humans the platysma muscle of the neck, palmaris brevis in the hand, and the dartos muscle in the scrotum are described as a discrete muscle of the panniculus carnosus.

Where does panniculus adiposus occur in the body?

The panniculus adiposus is the fatty layer of the subcutaneous tissues, superficial to a deeper vestigial layer of muscle, the panniculus carnosus. It includes structures that are considered fascia by some sources but not by others. Some examples include the fascia of Camper and the superficial cervical fascia.

What is the platysma?

The platysma is a broad muscle which arises from the fascia that covers the upper segments of the deltoid and pectoralis muscles. Its thin muscle fibers cross over the clavicle and proceed obliquely superiorly, laterally and medially over the neck.

What is the medical definition of panniculus carnosus?

Medical Definition of panniculus carnosus. : a thin sheet of striated muscle lying within or just beneath the superficial fascia, serving to produce local movement of the skin, and well developed in many lower mammals but in humans represented primarily by the platysma.

How is the panniculus carnosus retractor muscle removed?

Using a stereomicroscope a 15-mm circular area of skin, subcutis (with the panniculus carnosus), and retractor muscle are completely removed. This is essentially a full-skin-thickness removal. Next, remove the retractor muscle from the inner surface of the opposite side of the tented skin.

What kind of muscle is the panniculus adiposus?

panniculus carno´sus a muscular layer in the superficial fascia, well developed in certain animals; represented in humans mainly by the platysma.

When did Charles Darwin describe the panniculus carnosus muscle?

Charles Darwin, ‘The Descent of Man’ (1875). As described in Darwin’s beautiful words, the cutaneous panniculus carnosus (PC) muscle has long been considered a vestigial (Turner, 1870; Perrin, 1871) and ‘absolutely useless’ organ in humans; a remnant of evolution (Darwin, 1879 ).
