Sesamoid bones are small, seed-shaped bones that form within certain tendons where they rub against bone. They develop to minimize friction, act as pulleys for muscle contraction, and alter the direction of muscle pull. The largest sesamoid bone is the patella at the front of the knee. Others form at the back of the knee, in the hand, and below the big toe. Sesamoid bones lack periosteum and ossify after birth, differing from true long bones.

knee joint
Functionally, the knee joint is a condylar & modified hinge joint.
Transverse axis of movement is not fixed, & moves forward during extension & translates backward in flexion;
Along with extension & flexion, there is a conjunct rotation of femur on tibia(or vice versa) around a more or less vertical axis.

2. Synovial membrane
3. Ligamentum patellae
4. Tibial collateral ligament
5. Fibular collateral ligament
6. Oblique popliteal ligament
Arcuate popliteal ligament
Medial & lateral menisci
TIBIAL COLLATERAL LIGAMENT
The ligament consist of superficial & deep part . Both part are attached above to the medial epicondyle of femur. The superficial part extends downward & forward as a flattened band & is attached to the medial condyle & upper part of medial border of shaft of tibia along a rough strip of bone.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
2. SESAMOID BONES
• Sesamoid bones are seed like bony nodules.
• They develop in certain muscle tendons where
they rub against convex bony surface during
the movement of the joint.
• The rubbing surface of the sesamoid bone is
covered with an articular cartilage.
3. SITES OF SESAMOID BONES
1. Patella-in tendon of quadriceps femoris in front of knee joint.
2. Fabella-in lateral head of gastrocnemius behind the knee joint.
3. Pisiform-in the tendon of the flexor carpi ulnaris.
4. One sesamoid bone on the ulnar side of head of 1st metacarpal bone in
the tendon of abductor pollicis
5. One sesamoid bone in the tendon of peroneus longus where it binds
around the cuboid bone
6. Two sesamoid bones below the head of 1st metatarsal bone in the
tendon of flexor hallicis brevis.
4. FUNCTIONS OF SESAMOID BONES
1. Acts as pulleys for muscle contraction
2. Alter the direction of the pull of the muscle.
3. Minimize the friction of tendon against the bone to
prevent it’s attrition.
5. CHARACTERISTICS OF SESAMOID BONES
1. Develop in the tendon of the muscles.
2. Devoid of periosteum.
3. Ossify after birth by multiple centers.
4. They lack haversian system.
6. 🔹patella is the largest sesamoid bone in the body and the
cartilage covering,its articular surface is the thickest
articular cartilage.
🔹sesamoid bones are not true bones.(Not covered by
periosteum)
