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.
1 The nose has two cavities, separated from one another by a wall of cartilage called the septum. 2  The shape of the nasal cavity is complex. 3  In the olfactory (smelling) portion of the nose, most of the lining is mucous membrane. A small segment of the lining contains the nerve cells that are the actual sensory organs. Fibres, called dendrites, which project from the nerve cells into the nasal cavity, are covered only by a thin layer of moisture.
