Q. Slipped
Disc is one of the frequent causes of Backache. What are the function / purpose
of Disc? What is Sciatica? What is PID?
Ans.: Between two adjacent vertebras is fibro
cartilage (rubber washer like) structure. This is called as Inter vertebral
Disc.
The Function of this disc is
to prevent friction of vertebra on each other, reduce the shocks on the vertebral column, prevent the degeneration
of vertebra; it also gives the Flexibility to the vertebral column.
Q. What is
the component/composition of the vertebral disc?
Ans.:
It is composed of 2 portions the central is called nucleus pulposus &
peripheral or in the outer region the annulus fibroses.
Q. What
occurs in PID?
Ans.: Due to repeated back strains
there is tear in posterior portion of the disc and part of it slide behind
where there are components of nervous system, the spinal cord, nerve roots or
the nerves. This causes pressure on the spinal cord, or nerve roots or on both
.Due to irritation of these structure these is pain and symptoms like loss of
power or sensation.
Ans.: The
brain, spinal cord and nerves form the nervous system. The spinal cord starts
from the skull & extends down in the vertebral column ending just below the
thoracic spine. The spine. The spinal cord is enclosed in the vertebral column
which is a protective frame work for it. From either sides of from the gap
in between 2 vertebras nerve roots come out.
Multiple nerve roots from
various vertebra bodies join together to form a network called nervous plexus
from these plexus emerge out nerves which comes towards the limbs.
In the lower limb – 2 nerves
come down the femoral and sciatic.
In the upper limb -3 nerves
come down-median, ulnar, radial.
When there is pain coming down
along this sciatic nerve. It is called sciatica.
The pain along this nerves run from back of
the thigh into the calf into the foot, this is called Sciatica.
Q. What is
Spinal Instability?
Ans.: A stable structure stands up well, while an
unstable structure tends to fall.
Similarly, the spine also has
to be stable. The human spine is a unique marvel.
It is stable as well as
flexible Because of the stability we can
stand erect our two feet while rest of the animal kingdom has to support
themselves on 4 feet (Quadruped).
It is flexible, so gymnast can
do acrobats and yogi scan do various asanas.
Stability of the spine is due to the inter vertebral joints which are positioned
against each other as two hand , held (clasped ) in SHAKE HAND position.
It prevents one vertebra
gliding on the other vertebra.
Q. Why is
Stability needed? What will happen if one vertebra glider on another?
Ans.: If
one vertebra moves or glides on another. It was cause injury to the delicate
nervous system.
Ambien is generally recommended for short-term use, typically no more than 2-4 weeks. This is because Ambien can lose its effectiveness over time and can also lead to dependence. If you have chronic insomnia, you should talk to your doctor about other treatment options, such as cognitive behavioral therapy or other medications.
