(n.) The superficial layer of cells lining the alimentary canal and all its appendages, all glands and their ducts, blood vessels and lymphatics, serous cavities, etc. It often includes the epidermis (i. e., keratin-producing epithelial cells), and it is sometimes restricted to the alimentary canal, the glands and their appendages, -- the term endothelium being applied to the lining membrane of the blood vessels, lymphatics, and serous cavities.

Squama
Definition:
(n.) A scale cast off from the skin; a thin dry shred consisting of epithelium.
Example Sentences:
(1) The Indians have the lowest, longest squamae, differing most from the whites.
(2) Both sides of temporal squama were found to be quite thin.
(3) Nevertheless, a very recently published study has shown, using cat squamae, clinical efficacy on bronchial, nasal and ocular symptoms.
(4) The monitor is fitted flush with the inner table through a burr hole in the temporal squama.
(5) While the facial skeleton is reduced only by 10-15% if compared with the norm, the cerebral part is striking by its extraordinarily small dimensions (smaller by 30-40% in comparison with the norm), particularly in the area of the frontal bone squama.
(6) The shock caused a fall with severe craniocerebral injury with fracture of occipital squama and subacute epidural haematoma in the posterior cerebral fossa.

(8) There are few studies on the efficacy of desensitization to animal squamae (epithelial debris).
(9) The pars basilaris is biometrically independent of the squama; it could well be described with, and regarded as an extension of, the body of the sphenoid if it were morphologically separated from the rest of the occipital bone; there is thus good cause to describe in Man a spheno-occipital 'clivus'.
(10) The study of the curvatures of the squama shows that fossil Man agrees with present day Man in that when the occipital is rounded, the parietal is not, and the skull is low and elongated.
