PTI Lec 7&8 Flashcards
Intimately related with
reflex systems associated with stab of the head and eyes,vestibular fn & proprioceptive systems
Distributes load from
head and upper limbs while maintaining mechanical stability of thehead-neck system
Will lead to
- Pain Because of the trigeminal nerve.
- Dizziness Mixed messages, the vestibular and theoccular, and the propioception, all give mixedmessages.
- Unsteadiness Vertebral arteries can also be affected.
- Difficulty swallowing
Ligamentous systems
20% of stability
End range control
Muscular System
80% of stability
Mid range control
More often used
Must work harder if lig. Injury
Superficial
Scalenes Sternocleidomastoid (Upper trap) Sudden movement. Function – Maintaining Equilibrium of external forces so that the load transmitted to the spinalsegments can be controlled by deep muscles
These are the tripple S
Deep
Longus Coli
Multifidi
in wiplash, need to trainthis muscle, the longus coli.
Function
– Create cervical column to support the cervical spine Segmental control.
Synergy
grouping a set of muscles to accomplish a task
•CNS controls a synergy pattern vs individual ms
•Based on direction, spine position, posture and moment arm
Superficial vs Deep cervical spine synergy
•Balance of stability and mobility
•Further divided by direction ie. neck
flexor synergy
Cervicoscapularsynergy
•Relation of the scapula duringcervical spine
motions
Balance between deep neck & superficial (sf) extensor synergy
Deep = multifidi,
semispinalis cervicis, and the longus coli
• Sf = semispinalis capitisand splenius capitis and the SCM.
The cervicis of the splenius is deep and the capitis of splenius is superficial.
The cap is super
The cer is deep
A is before c.
Function of the thoracic
` Accommodates the expansion and recoil of
the lungs
` Provide a stable base for the head and neck ` Provide a stable platform for shoulder girdle attachment and movement
` Required to perform associated movements along with neck, lumbar, and shoulder movement
` Absorb shock from the extremities
Disruption of the thoracic function
` Affects breathing pattern ` Can lead to cramps with running ` Disrupt Cervical movement ` Affect Shoulder function (can lead to impingement) ` Impair shock absorption placing increasedstress to other joints
These are all the things that we did say was.
To aupport the head, to absorb shock, to allow for breathing, and to allow for the connection of the UE to the body,
There are muscle that attach to the upper ribs, and so
the function if the thoracs affects the cervicals. There aredeep muscles which we are not sure what they do. The
intercostals can stablize the thorax, the ribs need a little
bit of back up during breathing, because both the
intercostals are activated while we are breathing.
Stability of each level of the thorax.
Multifidi are also deep muscles.
