Causes of Pale Skin, Pallor, Paleness, Grey Skin. Pallor, aka pale skin, paleness, grey skin, is the loss of color in comparison to your normal skin color. Pale skin is not a concern if your skin paleness is caused by a fair complexion or lack of sun exposure. However, paleness may be a health concern if your usual skin pigment goes grey.
The inside of your nose is lined with a moist, thin layer of tissue called a mucous membrane (say: MYOO-kus MEM-brayne). This membrane warms up the air and moistens it. The mucous membrane makes mucus, that sticky stuff in your nose you might call snot.
The inner lining of the nose consists of mucus membrane that contains mucus-secreting glands. Mucus is a thin secretion made up of water, antibodies and proteins. The mucus helps to keep the nasal passages moist and prevent dust or infective particles suspended in the air from reaching the lungs. In some conditions, the mucus production increases and manifests in the form of a running nose.
