Musculoskeletal System Abbreviations - 3- Lesson 239

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 a systemic autoimmune disease. Due to the consequences of this disease tissue injury and inflammation occur, as the immune system once affected by SLE affects the cells and tissues of the body.  The disease flares up in remissions and also affects many organs in the body such as nerves, urinary system, liver, blood arteries and veins, skin, cardiovascular system, and joints. Corticosteroids and other immunosuppressants are needed to relieve from SLE symptoms. SLE disease occurs mostly in women for about 90% and 10% men.

2. L1-L5: This abbreviation represents five lumbar vertebral bones of the spinal cord.  These five lumbar bones present in between the thoracic and lumbar bones. The special feature of these bones is the nonexistence of foramen transversarium inside the transverse processes and also the facets on the surfaces of the bone body.

3.  T1-T12:  This abbreviated form stands for the twelve vertebral bones of the spinal cord that presents between cervical bones and lumbar bones. The special feature of these bones is they joined with 12 rib bones and so they combine to form the thoracic cage.

4.  TMJ:  This musculoskeletal system abbreviation is signified as temporomandibular joint. This TMJ area attaches the skull bone to the mandible area.

That’s all readers.  From the next lesson, we are going to introduce a new system called Integumentary system or Skin. Okay.
