Cells that do not have a nucleus
Retinal cancer is a cancer that arises in the cells of the retina. The retina is the layer of cells in the back of the eye where light is converted to nerve impulses.
radiation and convection and nerve cells in the skin
High doses of radiation exposure lead to higher chances of having cancer later in life. A dose of 100 rems will cause some initial signs of radiation sickness, such as loss of white blood cells, nausea, vomiting, and headache. Some loss of hair may occur, and nerve cells and those that line the digestive tract will be damaged.
either the light sensitive cells in the retina are not working or the optical nerve is damaged
nerve tissue
Nerve tissue
a nerve tends to refer to a group of nerve cells.
Connector nerve cells connect the sensory nerve cells with motor nerve cells and allow for decision making.
X, Number 10- the Vagus Nerve is the one that is connected with abdominal organs."The vagus nerve (n. vagus) (X pair) is mixed. Its motor fibers from the cells start motor nucleus, and sensitive - sensitive ganglion cells from occurring in the jugular orifice. From the brain of the vagus nerve goes behind the olive tree, and the skull - through the jugular hole and is divided into many branches, bound to the organs of the head, neck, chest and abdominal cavities. "-from my Atlas of Human Anatomy
The retina has two types of light-sensitive nerve cells. They are called rods and cones. Cones are more sensitive, so they can respond to lower light levels (and there are more of them). However, the rods are responsible for color vision. They come in three different varieties, each sensitive to different wavelengths (colors) of light. Since the rods are represented more heavily in the center of the visual field, we have little color vision on the periphery.
