Sweat Glands and Sebaceous Glands - Lesson 241

-
In this blog post, we are going to deal about integumentary system functions. As we’ve already studied, integumentary system consists of hair, nails, and some glands in it. Apart from protecting the body from outside, skin is also enclosed of two sorts of glands and those glands give off important discharges or secretions.

There are two types of glands under the skin, such as sweat glands and sebaceous glands. The main duty of these sweat glands is to produce dilute water like solution called sweat. Sebaceous glands create a slippery or greasy discharge called sebum. These two skin fluids are passed on to the external brinks of the skin through channels of tiny tube-like structures called ducts and send out from the skin via cavities or minute openings called pores. The liquid sebum makes easier to oil the outside of the skin. The sweat facilitates to cool the body as it disperses from the surface of the skin.

Whenever the body feels excessive heat stimulation from the environment, it kindles the heat centre of the brain and sends impulses from the nerve fibers of the skin from the surface of the body. These nerve impulses from the nerve fibers of the skin cause the blood vessels of the body to dilate and so they bring the blood to the outside of the body, and so allow the sweat glands to produce the watery secretion called sweat.  By this way, excessive heat from the body is carried away and balances the over heat or chillness of the body.

Palliative- Means just soothing or painkilling, not curing completely that is not possible. 6. PET scan or positron emission tomography- Radioactive materials are administered using intravenous route and these substances give out positrons. They generate a cross-sectional picture of the metabolism of the body. These images symbolize local concentration of the radio...

Today, we will know about an interesting medical term in medical language. This post is just to know about a different thing in the medical language, though this word is used very rarely in our day-to-day medical transcription work. The longest medical word is "Pneumonoultramicroscopicsilicovolcanoconiosis"!!!!!. Can you read at least Pneumonoultramicroscopicsilicovolcanoconiosis.  Now, we will see the meaning of this word.  To know the meaning shall we split the word by word. Okay.  1.  Pneumono 2.  Ultramicrosopic 3.  Silico 4.  Volcano 5.  Conosis. So, Pneumonoultramicroscopicsilicovolcanoconiosis comprises of 5 medical words and in combination, they give a meaning of a certain kind of disease condition related to lungs.  Now, we will see the meaning of each to get the combined understanding of the longest medical word. Pneumono means lungs, ultramicroscopic - means minute, silico means silicon, volc...
