this presentation describes the detail anatomy of Temporo-mandibular joint with respect to its articulating surfaces, ligaments, muscles and blood and nerve supply.
The temporomandibular joint is the joint of the jaw and is frequently referred to as TMJ. The TMJ is a bilateral synovial articulation between the mandible and temporal bone. The name of the joint is derived from the two bones which form the joint: the upper temporal bone which is part of the cranium (skull), and the lower jawbone or mandible.
There are six main components of the TMJ.
Mandibular condyles
Articular surface of the temporal bone

Temporomandibular joint, a facial joint commonly undergoes internal derangement due to the abnormal position of the articular disc in relation to the condyle. Internal derangement of the TMJ is explained in detail in this presentation.
Detailed discussion on diagnosis and management of TMJ ankylosis. Surgical anatomy and applied aspects of TMJ is discussed. Reconstruction of ramus-condyle unit is also discussed. Compications of TMJ surgery are also discussed

A medical document is a comprehensive written record used in the healthcare industry to capture and communicate important information about a patient's health and medical care. It typically includes:
Patient Information: Basic details like the patient's name, age, gender, contact information, and identification number.
Medical History: A summary of the patient's past medical conditions, surgeries, allergies, medications, and any relevant family medical history.
Diagnoses: Any medical conditions or diseases diagnosed by healthcare professionals, along with details about their severity and progression.
Treatment Plans: Information about prescribed treatments, medications, surgeries, therapies, and other interventions, including dosages and frequencies.
Progress Notes: Regular updates on the patient's condition, responses to treatment, and any changes in their health status.
Lab Results and Imaging: Recordings of laboratory tests, blood work, imaging (such as X-rays and MRI scans), and their interpretations by medical professionals.
Consultations: Notes from consultations with specialists or other healthcare providers, along with their recommendations.
Informed Consent: Documentation that the patient or their legal guardian has been adequately informed about potential risks and benefits of procedures or treatments and has given their consent.
Discharge Summaries: A summary of the patient's stay in a healthcare facility, detailing their diagnosis, treatment, and any follow-up instructions.
Legal and Ethical Documents: Any legal or ethical documents related to the patient's care, such as advance directives, do-not-resuscitate (DNR) orders, or living wills.

The temporomandibular articulation is composed of bilateral, diarthrodial, temporomandibular joints (TMJs). Each joint is formed by a mandibular condyle and its corresponding temporal cavity (glenoid fossa and articular eminence),

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
