TMJ surgical anatomy and applied aspectsJoel D'silva
The temporomandibular joint (TMJ) allows for hinge and gliding motions that facilitate functions like chewing and speech. It is a synovial joint containing features like bone, fibrocartilage discs, fluid-filled cavities, and ligaments. The TMJ is unique in that its surfaces are covered by fibrocartilage instead of hyaline cartilage and it is the only joint with a rigid closure point provided by tooth occlusion. Development of the TMJ occurs relatively late in utero, beginning with the formation of cartilaginous condyles that later ossify and fuse to the mandible.
The temporomandibular joint (TMJ) is a synovial joint that connects the mandible to the temporal bone. It has two articulating surfaces: the condylar head of the mandible and the glenoid fossa and articular eminence of the temporal bone. Between these surfaces is the articular disk which divides the joint cavity into upper and lower compartments. The joint is surrounded by a fibrous capsular ligament lined with synovial membrane. The synovial membrane secretes synovial fluid to lubricate and nourish the articulating surfaces. Common clinical issues involving the TMJ include ankylosis where the condyle fuses to the temporal bone, and

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic.

Nano-gold for Cancer Therapy chemistry investigatory projectSIVAVINAYAKPK
chemistry investigatory project
The development of nanogold-based cancer therapy could revolutionize oncology by providing a more targeted, less invasive treatment option. This project contributes to the growing body of research aimed at harnessing nanotechnology for medical applications, paving the way for future clinical trials and potential commercial applications.
Cancer remains one of the leading causes of death worldwide, prompting the need for innovative treatment methods. Nanotechnology offers promising new approaches, including the use of gold nanoparticles (nanogold) for targeted cancer therapy. Nanogold particles possess unique physical and chemical properties that make them suitable for drug delivery, imaging, and photothermal therapy.
Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

18. Glenoid Fossa
• 1.2-1.3cm – eruption of deciduous dentition
• Anterior inclination increases drastically as teeth
erupt & becomes 3 times steeper in permanent dentition
Articular Eminence
• Outline and inclination dos not change markedly from
deciduous to permanent dentition
• Growth increases after complete eruption of lateral and
central incisors
Articular Disc
• The intermediate zone – vascularity reduces as the age
progresses
19. Stop growing at 20 years of age - continuous
adaptational responses.
Condylar head –
Decrease in convexity
Decrease in condylar height
Resorption more on lateral aspect than medial
In extreme cases, drastic changes may produce
disappearance of condyle

40. INNERVATION OF TMJ
- The trigeminal nerve , that provides both motor & sensory innervations to
muscles that control it.
- Afferent innervation – branches of mandibular nerve.
- Also by auriculo-temporal nerve as it leaves mandibular nerve behind joint &
ascends laterally & superior to wrap around posterior region of joint.
- Additional nerves – temporal & masseteric .
41. VASCULARIZATION
- predominantly
i) from posterior- superficial temporal artery
ii) from anterior- middle meningeal artery
iii) from inferior- internal maxillary artery
iv) others :
- the deep auricular
- anterior tympanic
- ascending pharyngeal arteries
- condyle, receives through its marrow spaces by “feeder vessels” from inferior alveolar
artery.
