It is a free tool for creating visual schedules.
In humans the whole sclera is white, contrasting with the coloured iris, but in other mammals the visible part of the sclera matches the colour of the iris, so the white part does not normally show. In the development of the embryo, the sclera is derived from the neural crest. The thickness of the sclera varies from 1mm at the posterior pole to 0.3 mm just behind the rectus muscle insertions. The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. Picto Selector is a free tool that makes it easy to choose and create pictograms for any purpose. You can choose from thousands of free pictos and combine them by theme, style, or usage into picto sheets, or create new pictos from your own images and text. From MC van der Kooij: Select from over 28000 pictos and combine them into picto sheets. Fast search options and categories to select from. Create you're own pictos from photo's and text. Create clock and time timer pictos. The sclera is perforated by many nerves and vessels passing through the posterior scleral foramen, the hole that is formed by the optic nerve. At the optic disc the outer two-thirds of the sclera continues with the dura mater (outer coat of the brain) via the dural sheath of the optic nerve. The thickness of the sclera varies from 1mm at the posterior pole to 0.3 mm just behind the rectus muscle insertions. The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. Picto-Selector is a free tool for creating visual schedules. It is used by many teachers and parents. But there are also reports of people using it in daycare for elderly people. The download contains over 28000 pictos (images) translated to English, Dutch, German, French, Danish and Spanish. The sclera website came to be because there was a need for new pictograms in Terninck, a day centre and home for adults with a mental disability. The people there used the pictogenda to offer them structure from day to day. The pictograms used in pictogenda are black and white. blue sclera A hereditary defect in which the sclera has a bluish appearance. The sclera is thinner than normal and is susceptible to rupture if the person engages in contact sports. n the opaque, fibrous, protective layer of the eye containing collagen and elastic fibers. It is commonly known as the white of the eye. Because the sclera is thinner in children, some of the underlying eye pigment is visible, making the eye appear slightly bluish. The sclera (from the Greek skleros, meaning hard), also known as the white of the eye, is the opaque, fibrous, protective, outer layer of the eye containing collagen and elastic fiber. The thickness of the sclera varies from 1mm at the posterior pole to 0.3 mm just behind the rectus muscle insertions. The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. blue sclera abnormal blueness of the sclera; it is a prominent feature of osteogenesis imperfecta and is also seen in certain other conditions. (See Atlas 1, Part B.). , pl. n the opaque, fibrous, protective layer of the eye containing collagen and elastic fibers. It is commonly known as the white of the eye. Because the sclera is thinner in children, some of the underlying eye pigment is visible, making the eye appear slightly bluish. Flexible Sheets, Picto Creator and Sclera Pictos = version 1.6. Posted on December 12, 2011 by Picto Selector. The version with all the new stuff is progressing nicely. A lot of changes needs to be tested but all the new features are added and complete now.
