The musculoskeletal system comprises the bones, muscles, cartilage, tendons and ligaments in the body. It provides form, support and movement. The muscular system includes voluntary and involuntary muscles that enable movement and maintain posture. The skeletal system comprises bones and joints, including 206 bones that make up the framework of the body. Bones are classified as flat, irregular, long or short. Joints include fibrous, cartilaginous and synovial joints like the ball and socket hip joint that allow movement. Together the musculoskeletal system provides structure, movement and protection to the body.

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.
BONE – AN INTRODUCTION
A bone is a rigid organ that constitutes part of the vertebrate skeleton.
There are around 270 to 300+ bones in Infants which gets reduced to 206 bones in adults.
Bones are dynamic structures that are undergoing constant change and remodelling in
response to the ever-changing environment.
Bones support and protect the various organs of the body, produce red and white blood cells,
store minerals, provide structure and support for the body, and enable mobility.
It has a honeycomb-like matrix internally, which helps to give the bone rigidity.
The largest bone in the body is the femur or thigh-bone, and the smallest is the stapes in
the middle ear.
The topic includes:
definition and function bone
classification of bone according to shape, development, region and structure
gross structure of long bone
parts of a bone (epiphysis, diaphysis, metaphysis and epiphysial plate of cartilage)
blood supply of bone
growth of a long bone
Tunica Interna – innermost endothelium of simple squamous epithelium + basement membrane
Arteries – have an “internal elastic lamina” of elastic CT to allow for expansion under pressure
Veins – may have “valves” (folds of endothelium + CT) to prevent backflow of blood due to low pressure Microscopic, very thin-walled vessels comprised of endothelium with basement membrane; allows for filtration and reabsorption Found in all tissues of the body except for those that are “avascular” Usually form branching networks (“capillary beds”) within tissues for increased surface area blood flow into capillaries may be regulated by “pre- capillary sphincters” may have a central or “thoroughfare” channel that provides direct connection between “metarteriole” (terminal end of arteriole) & venule
The musculoskeletal system is made up of bones, cartilage, ligaments, tendons and muscles, which form a framework for the body. Tendons, ligaments and fibrous tissue bind the structures together to create stability, with ligaments connecting bone to bone, and tendons connecting muscle to bone.
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
A detail account of Bones, their histological features, classification, composition, Formation, blood and nerve supply, functions, plus some interesting facts about bones.

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.
How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. Musculoskeletal system
• The musculoskeletal system is made up of the body's bones (the
skeleton), muscles, cartilage, tendons, ligaments, joints, and other
connective tissue that supports and binds tissues and organs
together.
• This system provides form, support, stability & movement to the
body
• It comprises of Muscular System and the Skeletal System
4. Functions of Muscular system
• Locomotion
• Movement
• Posture formation and its maintenance
• Assistance in blood circulation and respiration
• Protection and support to the viscera
• Production of strength by converting chemical energy to mechanical
energy.
• Contribution to the functions of digestion, defecation, urination and the
process of child birth.
• External expression of emotions
6. Muscle:
a band or bundle of fibrous tissue in a human or animal body that has the ability to contract,
producing movement in or maintaining the position of parts of the body.
Classification of muscles
on the basis of structure and function
Smooth muscles
1.Maintain flow of fluids
along tissue walls.
2.Fatigue slowly.
3.Found in lungs,
stomach,oesophagus and
intestines.
Cardiac muscles
1.Controlled by central
nervous system and
“Pacemaker” cells.
2.Donot fatigue.
3.Found only in heart and tips
of blood vessels.
Skeletal muscles
1.Aid in voluntary movement.
2.Fatigue more rapidly than
other muscles.
3.attached to skeleton.
10. The Skeletal System
• Forms framework of the body.
• Bone is the hardest part of the body.
• No. of bones in adult human body =206
• Total weight of skeletal system = 15% of total
body weight.
• The skeletal system =Bones + Joints.
11. The bones
• Each bone is supplied by nerves, blood vessels & lymphatic vessels.
• Composition of bone - Calcium & Phosphorus.
• Bone Marrow - Soft core of the bone . Blood cells are produced in the
marrow.
• Cartilage - Softer than bone . e.g. Ear lobe ,nose .
13. Classification of bones
Flat bone Irregular bone Long bone Short bone
1.They are thin like
plate.
2.They protect organs
as they cover them.
3.Cranial bones of the
skull, Sternum, Ribs &
Scapulae
1.Complex and
irregular in shape
2.Example: Vertebrae
1.Length is greater
than the width
2.Slightly curved for
better strength
3.Bones of hands and
thighs
1.Cubical in shape
2.Equal in length &
width.
3.Bones of wrist &
ankles
15. Joints
• A point where two bones or bone and a cartilage contact each
other is called Joint or an Articulation.
• Two bones are held together by a flexible connective tissue
• Most of the joints permit the movement within particular limit.
• While some joints restrict the movement.
17. Types of joints
Fibrous joints Cartilaginous joints Synovial joints
1.The articulating bones are
held very close
to each other by a fibrous
connective tissue.
2.Very limited movement is
possible or there is no
movement at all.
3.Joints between shafts of the
ulna & radius or tibia and fibula,
Joint of the skull.
1.The joining material is
cartilaginous tissue.
2.Immovable in nature.
3.Joint between first rib and the
sternum.
4.Portion of intervertebral disc is
cartilaginous.
5.Vertebral joints are slightly
movable.
1.Joints of the bones move
freely upon each other.
2.Synovial cavity – space
between two articulating bones
3.Sleeve like articular capsule,
covers the joint.
4.The outer fibrous layer of the
capsule prevents dislocation.
5.The inner membrane secrets
synovial fluid, lubricating &
nourishing the joint
19. Classification of Synovial Joints
1) Gliding Joint - e.g. carpel & tarsal bones.
2) Hinge Joints - e.g. elbow & knee joints.
3) Pivot Joint - e.g. Between first vertebra (atlas) & second vertebra (axis).
4) Ball & socket Joints- e.g. hip & shoulder jt.
5) Ellipsoidal Joint - e.g.wrist joint.
6) Saddle Joint – e.g. thumb.
*Synovial fluid- Synovia, more often called synovial fluid, is a viscous fluid found in
the cavities of synovial joints.
*The functions of the synovial fluid include: reduction of friction —synovial
fluid lubricates the articulating joints.

21. Functions of skeletal system
1) Forms framework of the body & gives to the shape to the
body .
2) Protection of vital organs
3) Movement - mobility & stability.
4) Production of R.B.C.
5) Calcium metabolism
