The tapetum lucidum (Latin for 'bright tapestry, coverlet'; / təˈpiːtəm ˈluːsɪdəm / tə-PEE-təm LOO-sih-dəm; pl.: tapeta lucida) [1] is a layer of tissue in the eye of many vertebrates and some other animals. Lying immediately behind the retina, it is a retroreflector.

The tapetum lucidum is a biologic reflector system that is a common feature in the eyes of vertebrates. It normally functions to provide the light-sensitive retinal cells with a second opportunity for photon-photoreceptor stimulation, thereby enhancing visual sensitivity at …

2019年11月22日 · The tapetum lucidum is a layer of the eye in some species of animals. This membrane is located behind the retina on the back of the eye. It reflects light and causes the eyes to appear to glow in the dark. Many nocturnal animals have this membrane, including cats, dogs, horses, cattle and fish.

…layer of guanine called the tapetum lucidum, which reflects light and causes the eyes to shine at night when illuminated. Cats have good senses of sight and hearing, but their sense of smell is not as developed as that of the canids, a fact suggested by the cat’s short snout.

The tapetum is a membrane located behind the retina that reflects back the light that has gone through the retinal cell layers, increasing light detection by photoreceptor cells. From: Progress in Brain Research, 2012

The meaning of TAPETUM is any of various reflective membranous layers or areas especially of the choroid and retina of the eye.

The tapetum lucidum is a reflective layer located at the back of the eye in many animal species, which helps improve night vision. It reflects light so that it crosses the retina a second time, increasing the amount of light captured by photoreceptors and …

A tapetum lucidum is a mechanism to enhance visual sensitivity by reflecting or diffusing light back towards the photoreceptors and is common in animals active under low light (scotopic) conditions, either as a consequence of their nocturnal, crepuscular, or arhythmic lifestyle or because they inhabit deep or turbid waters (Rodieck, 1973).

2023年5月29日 · The tapetum lucidum is a layer of tissue in the eye of many vertebrates, e.g. cats, dogs, birds, fish, etc. but not including humans. This membrane makes the eyes of these animals shine or glow when illuminated in the dark. It is found behind or within the retina.

Not all primates have a tapetum lucidum; it is more commonly found in nocturnal species that require enhanced vision in low-light environments. The tapetum lucidum can cause the eyes of animals to appear to glow when light shines on them at …
