2. INTRODUCTION OF JOINTS
Joint (or articulation)-
the junction
between two or more bones.
With the exception of the
hyoid bone, every bone in the
body is connected to or forms a joint.
There are 230 joints in the body
3. JOINT FUNCTIONS
1. Hold the skeletal bones together
2. Allow the skeleton some flexibility so gross
movement can occur
3. Make bone growth possible
4. JOINT CLASSIFICATION
Joints are classified by:
movement or tissue type
Movement
1. Immovable
2. Slightly Movable
3. Freely Movable
Tissue (more common)
1. Fibrous
2. Cartilaginous
3. Synovial
5. THREE GENERAL GROUPS OF
JOINTS
Fibrous: classified by Sutures,
Syndesmosis, and Gomphosis.
eg skull bones, pelvic bones and
sternum.
6. THREE GENERAL GROUPS OF JOINTS
Cartilaginous: Connected
entirely by cartilage
E.g. vertebral column,
pubic bones, diaphysis
and epiphysis, ribs
joining the sternum.
7. THREE GENERAL GROUPS OF JOINTS
Synovial: Most common and
most movable joint.
Eg knee, hip, elbow joints
8. SYNOVIAL JOINTS
Articular ends covered in hyaline
cartilage and held together by dense
connective tissue
Joint capsules made up of ligaments
(outer layer) and synovial
membranes (inner layer)
Some synovial joints have shock-
absorbing pads called menisci and
fluid filled sacs called bursae.
9. THERE ARE SIX TYPES OF
SYNOVIAL JOINTS…
Ball-and-Socket Joint
Condyloid Joint
Gliding Joint
Hinge Joint
Pivot Joint
Saddle Joint
11. Structures within the Synovial Joints
Joint Capsule - Is made up of tough, fibrous connective tissue running from one bone to another -
completely surrounding and enclosing the joint like a sleeve. It provides stability to the joint and is
reinforced by ligaments.
Ligaments - Ligaments cross over joints, joining bone to bone. They are designed to assist the joint capsule
and maintain stability by limiting specific movements and can also control the degree and direction of
movement that occurs. Joint can become unstable with injury (eg overstretching).
Synovial Membrane - Is a thin sheet that lines the interior of a joint capsule. It secretes synovial fluid into
the cavity.
Synovial Fluid - Acts as a lubricant, keeping the joint well oiled ant the moving surfaces apart. The fluid
forms a cushion like protection between joints that don’t always fit together, as well as removes waste
and provides nutrition for the cartilage. The viscosity of the fluid can vary according to the physical
activity of the joint. A decrease in temperature increases the viscosity of the joint while an increase in
temperature decreases the viscosity.
Hyaline Cartilage - This cartilage is smooth, shiny elastic tissue that covers the ends of bones in synovial
joints. It allows them to move freely over each other.
Tendons - Tendons are inelastic and strong tissue that attaches muscle to bone. They assist in movement –
helping muscles pull across the joints on the bones.
Bursae - They are closed sacs, which are lined with synovial membrane. Bursae can be found in spaces
where friction is likely to occur such as between tendons and ligaments. They also secrete synovial
fluid in order to reduce friction and prevent wear and damage.
12. Ball-and-Socket Joint: consists of a
bone with a ball-shaped head that
attaches with the cup-shaped cavity
of another bone. This type of joint
allows for a wider range of motion
than any other kind. It permits
movement in all planes, and a
rotational movement around a
central axis. Two examples of this
type of joint would be the hip and
shoulder joints.
BALL-AND-SOCKET JOINT
13. Condyloid Joint: an oval-shaped
condyle of one bone fits into an
elliptical cavity of another bone.
This type of joint permits a variety
of movements in different planes.
It however, does not permit
rotational movement. Examples of
this type of joint would be the
joints between the metacarpals
and the phalanges.
CONDLYOID JOINT
14. GLIDING JOINT
Gliding Joint: has nearly flat or slightly
curved articulating surfaces. This type
of joint allows sliding and twisting
movements. Some examples of this
type of joint include, the joints within
the wrists and the ankles, the joints
between the articular processes of
adjacent vertebrae, the sacroiliac
joints, and the joints formed by ribs
(2-7) connecting with the sternum.
JOINTS WITHIN THE
WRISTS AND THE ANKLES
15. Hinge Joint: the convex surface of
one bone fits into the concave
surface of another. This type of
joint permits movement in one
plane only. This movement
consists of flexion and extension.
Two examples are the elbow and
the phalanges.
HINGE JOINT
16. Pivot Joint: the cylindrical surface
of one bone rotates within a ring
formed of bone and ligament.
Movement is limited to the
rotation around a central axis.
Examples of this type of joint are
the joints between the proximal
ends of the radius and ulna.
PIVOT JOINT
17. Saddle Joint: forms between bones
whose articulating surfaces have both
concave and convex regions. The surface
of one bone fits the complementary
surface of the other bone. This type of
joint permits a variety of movements. An
example would be the joint between the
trapezium and the metacarpal bones of
the thumb.
SADDLE JOINT
18.
19. EXAMPLES
EXTENSION—THE NECK IS EXTENDED,
AS IN LOOKING UPWARD TOWARD
THE CEILING (LEFT)
FLEXION—THE MOVEMENT IN
WHICH THE CHIN IS LOWERED DOWN
TOWARD THE CHEST (RIGHT)
LATERAL FLEXION MAY BE BEST
DESCRIBED AS TRYING TO PLACE THE
EAR UPON THE SHOULDER THROUGH
A SIDEWAYS MOVEMENT OF THE
NECK, DIRECTING THE EAR TOWARD
THE SHOULDER TIP ON BOTH SIDES
LATERAL ROTATION TO THE LEFT AND
TO THE RIGHT—THESE ARE SIMPLY
DIRECT LATERAL ROTATION TO
EITHER SIDE
These six movements may be slowly performed occasionally to stretch the neck
ligaments if they tend to feel tight. The movements can be performed at any time

the correct ROM exercises. Not all of these exercises
will be appropriate for all pts

34. Lubricate the joints
Increase the blood flow to the muscles / Joint
Increase muscle elasticity
Speed up the nerve message system from the brain to the limbs
Gently raise the heart rate

AN EFFECTIVE SUKSHMA VYAYAM SHOULD
35. SUKSHMA VYAYAMA
Group of exercise concerned with loosening up the
joints of the body.
Voluntarily giving slow movement to the joints with
awareness.
Each and every part of the body including the organs
& muscles are taken into consideration.
36. PROPER WORKOUT OF JOINTS ---
Stiffness in the physical level
Energy blockages in the pranic level
37. IMPORTANCE OF THE EXERCISE
Peace, balance and one pointed awareness which inturn brings
harmony in the physical level.
Since the movement is done slowly it slows down the brain
waves, further enhancing relaxation and awareness.
It has a great influence at the physical and pranic levels and
useful for harmonizing and improving the function of the
internal organs.
38. SITHILIKARNA VYAYAMA/STHULA VYAYAMA
Loosening exercises which are done very fast.
Principles –
To flex the back portion by stretching and relaxing
the spine.
39. EXERCISES / PRACTICES
Forward bending
Backward bending
Bending and twisting
Twisting
Side bending
40. RULES TO BE FOLLOWED ----
To be practiced step wise.
Be aware of your breathe and the parts of the body.
Be aware of your thoughts and feeling.
Count the steps.
Learn to synchronize each step in a group.
After every two – three movements relax quietly in
leg stretch position with eyes closed.
41. Stretch your muscle beyond the point of pleasant comfort
Vyayama vigorously in a very humid of very hot climate
Hold your breath during physical activity
Hyperventilate during Vyayama or at rest
Work through pain
Vyayama through illness or injury
NEVER
42. Start Asana immediately after vigorous activity
