Integumentary

The entire spine is covered with a thin layer of skin called the integumentary sheath, in which venom is concentrated. ❋ Unknown (2007)

As the stinger enters the flesh, the integumentary sheath surrounding the spine is ruptured and the venom escapes into the victim's tissues. 5Stingray venom is one of the most powerful vasoconstrictors found among the natural toxins. ❋ Unknown (2010)

The function of the integumentary system is to protect, nourish, insulate, and cushion the body from the harmful substances of the outside world. ❋ Inna Segal (2010)

The integumentary system consists of the skin, hair, nails, and certain exocrine glands. ❋ Inna Segal (2010)

So what should you avoid smearing all over the largest largest organ of the integumentary system? ❋ Unknown (2009)

In 1999, they first described the find in "A therizinosauroid dinosaur with integumentary structures from China," published in Nature ❋ Unknown (2009)

In a phylogenetic analysis of skeletal, integumentary and soft-tissue characters, Livezey (1996) concluded that the members of Aythyini fell into four major groups, which in branching order are: the stem or narrow-billed pochards, the redheads, the white-eyes, and the scaup. ❋ Darren Naish (2006)

It is preserved with simple quill-like integumentary structures that seem antecedent to the true complex feathers that evolved later. ❋ Darren Naish (2006)

Furthermore, probable ‘proto-feathers’ (rather simple quill-like integumentary structures, almost certainly the morphological ancestors of true, complex feathers) were present in compsognathids, basal tyrannosauroids and alvarezsaurids. ❋ Darren Naish (2006)

True feathers, so far as we know, were restricted to maniraptorans (the theropod clade that includes oviraptors, dromaeosaurs and birds), but simpler, filament-like integumentary structures appear to have evolved much earlier within theropod history, probably at or around the base of Coelurosauria. ❋ Darren Naish (2006)

Having mentioned tyrannosauroids, I might also note that basal forms combine proportionally small premaxillary teeth with quill-like integumentary structures that would have needed preening (or is grooming the correct term here?). ❋ Darren Naish (2006)

The current data from theropods shows that quill-like integumentary structures were present in theropods before one lineage gave rise to scansorial proto-birds. ❋ Darren Naish (2006)

The Yixian Formation is the now famous unit that has produced all those little coelurosaurs with feathers and other integumentary structures preserved, and Dilong is no exception. ❋ Darren Naish (2006)

Basal tyrannosauroids and other basal coelurosaurs that possess specialised premaxillary teeth that might have been used in preening/grooming of quill-like integumentary structures. ❋ Darren Naish (2006)

Similarly, while it is known that the effects inhibitors have on the thyroid can in turn lead to adverse effects on the digestive, cardiovascular and integumentary systems, it is not yet known what effect current concentrations of perchlorate have in the body. ❋ Unknown (2008)
