The neck contains many vital structures and connects the head to the torso. The skeleton of the neck includes 7 cervical vertebrae, the hyoid bone, manubrium, and clavicles. The neck separates into anterior and posterior triangles divided by the sternocleidomastoid muscle. The triangles contain muscles, vessels, and nerves. Conditions like torticollis can cause neck twisting that is treated with physiotherapy including massage, stretches, and exercises to improve range of motion.

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.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

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
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Introduction
• The neck is the bridge between the head and the rest of the body.
It is located in between the mandible and the clavicle, connecting
the head directly to the torso, and contains numerous vital
structures.
• Structures contained within the neck are responsible for
breathing, speaking, swallowing, regulation of metabolism,
support and connection of the brain and cervical spine, and
circulatory and lymphatic inflow and outflow from the head.
3. Bone of the Neck
• The skeleton of the neck is formed by the cervical vertebrae, hyoid bone,
manubrium of the sternum, and clavicles.
• These bones are parts of the axial skeleton except the clavicles, which are
part of the appendicular skeleton.
4. Cervical Vertebrae
• 7 cervical vertebrae form the cervical region of the vertebral column, which
encloses the spinal cord and meninges.
5. Hyoid Bone (Hyoid)
• Lies in the anterior part of the neck at the level of the C3 in the angle between
the mandible and the thyroid cartilage.
• Suspended by muscles that connect it to the mandible, styloid processes,
thyroid cartilage, manubrium, and scapulae.
• Does not articulate with any other bone.
6. • The hyoid consists of a body and greater and lesser horns and the lesser horn
is the attachment for the stylohyoid ligament).
• Functionally, the hyoid serves as an attachment for anterior neck muscles and
a prop to keep the airway open.
7. Fascia of the Neck
• Structures in the neck are surrounded by a layer of fascia but the two main divisions
are superficial fascia and deep cervical fascia.
The superficial cervical fascia extends
from the head down to the thorax and axillae.
In the neck, it contains the superficial
lymph nodes, cutaneous nerves, external
and anterior jugular veins, and
the platysma muscle. It is arranged loosely to
allow for neck movement.
8. The deep cervical fascia subdivides into the superficial layer of deep cervical
fascia, the middle layer of deep cervical fascia, and the deep layer of deep
layer of deep cervical fascia.
• The superficial layer of deep cervical fascia, or investing layer, lies between the muscles of the
neck and the superficial cervical fascia, encircling the sternocleidomastoid and trapezius muscles. It
attaches inferiorly to the scapula, clavicle, and manubrium. Superiorly, it attaches to the mandible,
mastoid process, superior nuchal line, and external occipital protuberance.
• The middle layer of deep cervical fascia, or the pre tracheal layer, runs from the mediastinum
inferiorly to the skull base superiorly. It has a muscular and visceral division. The muscular division
encloses the strap muscles, sternohyoid, sternothyroid, omohyoid, and thyrohyoid muscles. The
visceral division encloses the larynx, pharynx, esophagus, thyroid, parathyroid glands, trachea, and
recurrent laryngeal nerve.
• The deep layer of deep cervical fascia, or prevertebral layer, runs from the skull base to the
mediastinum. Its two divisions are the alar and prevertebral layers. These layers surround the deep
muscles of the neck and the cervical vertebrae, forming part of the retropharyngeal space.
9. Triangle of the Neck
• The neck separates into two triangles: anterior and posterior, with these
divided into additional triangles and anatomic areas.
• The anterior triangle is surrounded inferiorly by the sternal notch and
clavicle, laterally by the sternocleidomastoid, and medially by the trachea,
thyroid, and cricoid cartilages.
• The posterior triangle is bordered posteriorly by the trapezius muscle,
anteriorly by the sternocleidomastoid muscle, and inferiorly by the clavicle.

33. Clinical Anatomy
Torticollis
• Torticollis, also known as wry neck, is a dystonic
condition defined by an abnormal, asymmetrical head
or neck position, which may be due to a variety of causes.
• The term torticollis is derived from the Latin words
tortus for twisted and collum for neck.
34. Signs and Symptoms
• Torticollis can be a disorder in itself as well as a symptom
in other conditions.
• Other symptoms include:
• Neck pain
• Occasional formation of a mass
• Thickened or tight sternocleidomastoid muscle
• Tenderness on the cervical spine
• Tremor in head
• Unequal shoulder heights
• Decreased neck movement
35. Torticollis may lead to additional problems :
Flattening of the skull (plagiocephaly or brachycephaly) in
infants.
Movement that favors one side of the body, affecting the
arms, trunk, and hips. This can lead to strength imbalances,
such as an elevated shoulder and side- bending of the trunk.
This movement pattern can lead to delayed gross motor
development.
Developmental hip dysplasia.
Scoliosis.
Limited ability to turn the head to see, hear, and interact with
surroundings, which can lead to delayed cognitive
development.
Delayed body awareness or lack of self-awareness and
interaction.
Difficulty with balance.
Asymmetrical vision changes.
36. Diagnosis
• General History taking
• Birth History
• History of Trauma
• Neurological examination
• X-ray of cervical spine
• MRI
• USG - Muscular tissue, Colour Histogram
• Optometrist evaluation
37. Assessment :
• Observation of any asymmetries including facial, cranial, neck and positional preference
and presence of plagiocephaly.
• Observation of skin creases.
• Observation of infant in developmentally appropriate positions to detect asymmetry and
screen developmental milestones.
• Cervical active and passive range of movement testing.
• Upper and lower limb ROM screen, checking for hip dysplasia, which can be associated
with CMT, and spine asymmetry.
• Pain at rest and during movements.
• Palpation of sternocleidomastoid for size and elasticity and presence of mass.
• Screen of visual tracking.
• Screen muscle tone.
• Identification of Red flags and appropriate onward referral:
1. poor tracking
2. abnormal muscle tone
3. other features inconsistent with CMT
4. poor progress with treatment
38. Physiotherapy Management
Goals
• Improve child's ability to turn head between right and left
sides
• Improve child's ability to bring chin to chest
• Improve child's ability to orient their head to midline against
gravity
• Encourage child to lift head against gravity while lying on
stomach
• Allow child to experience proper weight shifting during
developmental activities including sitting, rolling, creeping and
walking
39. Early mild cases
Children with a mild degree of deformity reporting early for
the treatment can be managed with physiotherapy.
The physiotherapy procedures employed are:
I. Evaluation: Careful evaluation of ROM and the degree of
deformity.
II. Massage: Massage can relax the muscle preceding the
stretching maneuvers.
III.Thermo Therapy Modality: Carefully administered thermo-
therapy modality induces relaxation.
IV.Passive movements: The child is placed in supine position
with head beyond the edge of the table with the neck in
extension by positioning a pillow under the thoracic region;
Shoulders are stabilized by an assistant.
40. • To attain relaxation, all the movements of
the cervical spine are done in a form of slow
relaxed passive movements.
• This should be followed by sustained passive
stretching to the affected sternomastoid.
E.g. when the right sternomastoid is
involved the head should be gradually
bent inside flexion to the left, held there for a while
and then rotated gradually to the right. Try to gain as
much overcorrection as possible by applying gradual
traction to gain further stretching.
41. • Maintenance of Correction: Once
the correction is achieved.
It has to be maintained by passively
holding or keeping a sandbag.
E.g: Kineso taping, Cervical Brace,
Cervical collars.
• The same maneuver can be repeated during the subsequent
visits.
Active correction is best achieved by assisting the child head
to follow an object moved in the proper arc of correction. The
bright-colored sound producing object is ideal to attract the
child attention. – PNF: patients with neck extension can be
used to an advantage with emphasis on stretch and traction.
42. Post surgical PT management
• Hot packs for pain relief.
• Active movements of sternocleidomastoid to prevent post
surgery weakness.
• Free active movements in the direction of correction
followed by resistive exercises.
• Self correction in front of mirror.
• Specially molded cervical collar and maintenance of
correction during sleep.
