In the last lesson, we have learnt about the function of the skin. In this lesson, we are going to learn about the anatomy and physiology of the skin. Skin consists of three layears from the external surace of the body. The names of these three layers are epidermis, corium, and subcutaneous. In these three layers, the first and foremost outer layer epidermis is a thin cellular membrane, but the other middle layer called corium or dermis is fibrous and dense layer that is made up of connective layer, and the innermost layer of the skin is called subcutaneous, which is thicker than the other two layers and is made up of fat tissue. In this post, we will learn specifically about the outermost layer epidermis. Okay. Human skin contains nine parts generally. They are 1. Epidermis layer 2. Corium layer or dermis layer 3. Subcutaneous layer 4. Blood vessels 5. Lymph vessels 6. Nerve fibers 7. Hair follicle 8. Sebaceous glands 9. Sweat glands Skin - Epid...

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 enviro...

Hi all. So far, we’ve discussed about musculoskeletal system anatomy and functions, important medical terminologies and abbreviations.  From this lesson, we are going to deal about integumentary or skin system anatomy and functions i.e. about skin and its partner organs, such as skin glands, nails, and hair.  Integument means an envelope or a wrap or a cover. The weight of skin in human body is approximately 9 pounds and the length of the skin-covered area in the human body is approximately 20 to 23 square feet. Integumentary system consists not only of skin, but also consists of intricate structure of specialized tissues. Skin also has glands in it and these glands produce a number of solutions.  These fluids along with the nervous system accompanied with the integumentory system regulate the temperature state of human body. Primarily skin is a shielding membrane on top of the whole human body. It safeguards the profound body organs alongside too much passing a...

Hi, free online medical transcription learners, have you enjoyed the free course so far.   I need your timely feedbacks about the quality of the lessons and the quality of the site everyday and then only I can improve myself for your needs. Ok.   In this lesson we are going to learn about the last part of the lesson named Musculoskeletal System Important Abbreviations. As I am stressing you all again and again that you should read the lessons again and again and mug up the important terms and revise it once you complete the lessons of any system. You should also gradually increase your typing speed, the minimum need of words per minute for an average MT is 45. Free transcription dummy files for your practice will be added soon. Shall we continue the lesson? Come on. The abbreviations we are going to deal in this article are SLE, L1-L5, T1-T12, and TMJ and also their meanings. 1. SLE:   We should expand this abbreviation into systemic lupus erythematosus. This is...
