This document discusses the skeletal system and different types of joints in the human body. It begins by defining a joint and describing the three structural classifications of joints: fibrous joints, cartilaginous joints, and synovial joints. It then discusses the functional classification of joints based on their range of movement. The majority of the document focuses on describing the different types of synovial joints in more detail, including ball-and-socket, hinge, gliding, pivot, condyloid, and saddle joints. It concludes by outlining some common characteristics of synovial joints, such as hyaline cartilage, joint capsules, synovial fluid, ligaments, pads of fat, and articular discs.
All human joints including axial and appendicular skeleton will clear all the concepts and doubts of learner related to joints and different classification of joints with detail. Also, help student, learner, reader to communicate.

A joint is an articulation between two bones in the body and are broadly classified by the tissue which connects the bones. The three main types of joints are: synovial, cartilaginous and fibrous.
oint: The area where two bones are attached for the purpose of permitting body parts to move. A joint is usually formed of fibrous connective tissue and cartilage.

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.
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.

Joints
A joint is the site at which any two or more bones articulate or come
together. Joints allow flexibility and movement of the skeleton and
allow attachment between bones.

Structural classification
of joints
• Structural classification names and divides joints
according to the type of binding tissue that connects the
bones to each other. There are three structural
classifications of joints:
• Fibrous Joints - joined by dense regular connective
tissue that is rich in collagen fibers
• Cartilaginous Joints - joined by cartilage
• Synovial Joint - not directly joined the bones have a
synovial cavity and are united by the dense irregular
connective tissue that forms the articular capsule that is
normally associated with accessory ligaments. 4

Functional classification
of joints
Functional classification (movement)
Joints can also be classified functionally according to the type
and degree of movement they allow:
Synarthrosis - permits little or no mobility. Most synarthrosis
joints are fibrous joints(e.g., skull sutures).
Amphiarthrosis - permits slight mobility. Most
amphiarthrosis joints are cartilaginous joints (e.g.
intervertebral discs)
Diarthrosis - freely movable. All diarthrosis joints
are synovial joints (e.g., shoulder, hip, elbow, knee, etc.), and
the terms "diarthrosis" and "synovial joint" are considered
equivalent.

The bones forming these joints are linked with tough, fibrous
material. Such an arrangement often permits no movement. For
example, the joints between the skull bones, the sutures, are
completely immovable, and the healthy tooth is cemented into the
mandible by the periodontal ligament. The tibia and fibula in the
leg are held together along their shafts by a sheet of fibrous tissue
called the interosseous membrane. This fibrous joint allows a
limited amount of movement and stabilises the alignment of the
bones.
Fibrous joints

Cartilaginous joints
7
These joints are formed by a pad of tough
fibrocartilage that acts as a shock absorber.
The joint may be immovable, as in the
cartilaginous epiphyseal plates, which in
the growing child links the diaphysis of a
long bone to the epiphysis.
Some cartilaginous joints permit limited movement, as between the
vertebrae, which are separated by the intervertebral discs, or at the
symphysis pubis, which is softened by circulating hormones during
pregnancy to allow for expansion during childbirth.

Synovial joints
Synovial joints are characterized by the
presence of a space or capsule between
the articulating bones. The ends of the
bones are held close together by a sleeve
of fibrous tissue, and lubricated with a
small amount of fluid. Synovial joints are
the most moveable of the body.

Movements at synovial joints
Movement at any given joint depends on various
factors, such as the tightness of the ligaments
holding the joint together, how well the bones fit
and the presence or absence of intracapsular
structures. Generally, the more stable the joint,
the less mobile it is. The main movements
possible are summarized in the given table.

Types of synovial joint
Synovial joints are classified according to the range of movement
possible or to the shape of the articulating parts of the bones
involved.
Ball and socket joints
The head of one bone is ball-shaped and articulates with a cup-
shaped socket of another. The joint allows for a wide range of
movement, including flexion, extension, adduction, abduction,
rotation and circumduction. Examples include the shoulder and hip.
Hinge joints
The articulating ends of the bones fit together like a hinge on a
door, and movement is therefore restricted to flexion and extension.
The elbow joint is one example, permitting only flexion and
extension of the forearm. Other hinge joints include the knee, ankle
and the joints between the phalanges of the fingers and toes
(interphalangeal joints).

Gliding joints
The articular surfaces are flat or very slightly curved and glide over
one another, but the amount of movement possible is very restricted;
this group of joints is the least movable of all the synovial joints.
Examples include the joints between the carpal bones in the wrist,
the tarsal bones in the foot, and between the processes of the spinal
vertebrae.
Pivot joints
These joints allow a bone or a limb to rotate. One bone fits into a
hoop-shaped ligament that holds it close to another bone and allows
it to rotate in the ring thus formed. For example, the head rotates on
the pivot joint formed by the dens of the axis held within the ring
formed by the transverse ligament and the odontoid process of the
atlas.

Condyloid joints
A condyle is a smooth, rounded projection on a bone and in a
condyloid joint it sits within a cup-shaped depression on the other
bone. Examples include the joint between the condylar process of
the mandible and the temporal bone, and the joints between the
metacarpal and phalangeal bones of the hand, and between the
metatarsal and phalangeal bones of the foot. These joints permit
flexion, extension, abduction, adduction and circumduction.
Saddle joints
The articulating bones fit together like a man sitting on a saddle.
The most important saddle joint is at the base of the thumb, between
the trapezium of the wrist and the first metacarpal bone. The range
of movement is similar to that at a condyloid joint but with
additional flexibility; opposition of the thumb, the ability to touch
each of the fingertips on the same hand, is due to the nature of the
thumb joint.

Common characteristics of
synovial joints
13
Hyaline (articular) cartilage
The articular surfaces of bones are covered with hyaline cartilage. This
protects the bones tissue by smoothing and facilitating gliding movements
between the bone ends. It also helps to reduce friction between the bones.
Joint/articular capsule
This is a fibrous tissue encasing the joint, forming a capsule. It adds
stability to the joint and prevents unwanted material from entering the
joint.
Synovial membrane
The synovial membrane acts as a lining to the inside of the joint capsule
and secretes synovial fluid.
Synovial fluid
Synovial fluid fills the joint capsule; it nourishes and lubricates the
articulating surfaces and protects the joint by reducing friction. Synovial
fluid becomes less viscous (thick and sticky) with exercise.

Ligaments
Ligaments are tough non elastic, fibrous connective tissue joining
bone to bone. They restrict the amount of movement that can occur
at a joint and provide stability.
Pads of fat
Pads of fat fill the gaps in and around the joints helping to protect
the bones from wear and tear.
Articular discs (menisci)
Articular discs lie between the articular surfaces and are attached to
the capsule at the outer edge. Their function is to absorb shock,
protect the bones surfaces and maintain joint stability.
