Hello students, in this video we will discuss about retina.
00:06
The retina is the light sensitive tissue that lines the back of the eye.
00:28
It is made up of several layers of cells including photoreceptor cells, bipolar cells and ganglion cells.
00:54
The photoreceptor cells are responsible for converting light into electrical signals that are sent to the brain.
01:15
The bipolar cells and ganglion cells process these signals and send them to the brain.
01:33
The retina has a layered appearance with the photoreceptor cells being the most superficial layer and the ganglion cells being the deepest layer.
01:57
The bipolar cells are located in between the photoreceptor cells and the ganglion cells.
02:06
The retina is responsible for vision.
02:11
It converts light into electrical signals that are sent to the brain where they are interpreted as images.
02:40
The tapetum lucidum is a refractive layer of tissue that is found in the retina of some mammals.
02:49
It is located behind the rods and cones and it reflects light back through the retina increasing the amount of light that is available for vision.
03:18
Tapetum lucidum is most prominent in nocturnal animals such as cats and dogs.
03:26
It helps these animals to see better in low light conditions.
03:39
In humans, the tapetum lucidum is not well developed.
03:50
It is only present in a small area of the retina and it does not play a significant role in vision...
