indicates the potential pattern of secondary muscle guarding
If T4 is fully flexed and right side bending is introduced, which rotation will occur?
right
Rotation in the Thoracic spine will ________ if the segments are extended first.
decrease
Contraction of the Pec Minor will create?
Inhalation motions of Ribs 3-5
What position indicates the bilateral closed position of Thoracic facet joints?
extension
Which plane best describes the facet orientation in the majority of the Thoracic Spine?
Frontal Plane orientated
The thoracic spine is rotating to the right. What motion is occurring in the left ribs?
Inferior Torsion
Forced inhalation is created by?
Concentric contraction of agonists
What is a representation of the control of right thoracic sidebending?
EC of Left Erector Spinae
The client is presenting with an ERSrt at T4. What may also be present?
Superior Torsion of Rib 4 on the right
Inferior Torsion of Rib 4 on the left
What motion is most restricted in the thoracic spine due to the orientation of both the Spinous Processes and the Articular Facets?
extension
What direction does rotation occur during non-neutral mechanics in the vertebral column?
rotation occurs to the same side as sidebending
When the client performs forced exhalation at ribs 11 and 12, which muscle is responsible for stabilization?
Quadratus Lumborum
What represents Type 1 mechanics?
vertebra rotating lt and sidebending rt
How many pairs of ribs are there
12
the true ribs are______ they attach to the ______
1-7
sternum
false ribs are_____ They attach to_______
8-10
costal cartilage of rib 7
Floating ribs are______ they have no______
11-12
Ant. attchment
the diaphram is shaped like a
dome
the diaphram inserts
on to its self
when the diaphram contracts it __________interthoracic pressure-which in turn __________ the volume of the lungs. a vaccum is thus created causing air to ______ the lungs. this is called______
Decreases
increases
enter
inspiration
relaxation of the diaphragm _______interthoracic pressure. this is how air is _________from the lungs. this is normal exhalation.
increases
expelled
Normal inspiration
-Diaphragm contracts
-interthoracic pressure decreases
-creates a vaccum
air enters the lungs
Normal exhalation
-diaphragm relaxes
-interthoracic pressure increases
-air is expelled from the lungs
paradoxical breathing
-occurs with elevation and expansion of the rib cage
in paradoxical breathing the abdomen _________ protrude.
does not
paradoxical breathing is most likely done/created for _________reasons
aesthetic
paradoxical breathing may indicate__________
pulmonary disorder like asthma or pulmonary distress.
pulmonary disorders may present with
parasthesia of the diaphram
Paradoxical breathing is
FORCED
paradoxical breathing will
over work the
scalene and intercostal muscles by increasing their contribution to the respiration process
Muscles with an inferior insertion assist with
forced inhalation
muscles with an superior insertion help with
forced exhalation
the rib facets articulate with the bodies of the thoracic vertebrae at the
demifacets
(one above and one below)
The rib tubercle articulates with ______ and serves as attachment for _______
the TPS
ligaments
the shaft of the rib is torsioned along its _________. this creates ______ in the ribs
long axis
tension
Ribs __, ___, and ___ only articualate with the full facet on the corresponding vertebrae
1
11
12
Ribs 1, 11, and 12 ______ articulate with the TPs of thoes vertebrae
DO NOT
At the posterior articulation, the rib ______/______ on the axis passing through the joints.
This relationship changes dependant on the shape of the thoracic vertebrae
Glides/pivots (roll)
in the superior thoracic, the axis is directed more _______ thus the elevation of the ribs increases the__________ of the thoracic cage
lateral
anterior diameter
in the inferior thoracic the axis is directed more _______, thus elevation of the ribs increases the ________of the thoracic cage
posterior
Lateral diameter
Inhalation elevates the thoracic cage and moves the ribs________, articulating surface (tubercle) rolls_______
superior
inferior
Exhalation depresses the thoracic cage and moved the ribs ________, Articulating surface (tubercle) rolls_________.
Inferior
superior
The thoracic vertebrae glide ________on inhalation ________ the thoracic cage with them.
posterior
pulling
The thoracic vertebrae glide _________ on exhalation _______ the thoracic cage with them
anterior
pulling
As the thoracic spine extends, the rib heads ______. This motion is described from neutral position as a __________
torsion
superior torsion
One rib articulates with
2 vertebral bodies and 1 TP
The articular processes of throacic vertebae
help to control and limit movement
upper ribs move in a _____ motion
pump handle
the mid ribs move in a _________ motion
bucket handle
the lower ribs move in a _________ motion
caliper
external inter costals are muscles of_______
inspiration
insertion to the rib below
internal intercostals are muscles of _______
expiration
insertion to the rib above
quiet expiration is
passive
ACCESSORY MUSCLES of inspiration
SCM
SCALENES
Surratus ant.
ACCESSORY MUSCLES of expiration
abdominal muscles
bowals law
Increasing volume = decrease in pressure creating a vaccume and vise versa
Thoracic Flexion KIN
Plane - sagital Axis -X
Translation-Horizontal
Osteo- Vertebrae translated anterior, TPs and SPs distract
Arthro - Disc displaces posterior and fecets open
Force - concentric contration of RA, Obliques then gravity
