the cervical spine has an important role in providing the proprioceptive input
this is reflected in the abundance of cervical mechanoreceptor
their central and reflex connections to the
cervical region are found in high densities especially in the suboccipital
where there are up to 200 muscle spindle per gram
the number is considerable when compared to the first lumbical in the thumb where there are 16 muscle spindle per gram

cervical afferent are also involved in three reflexes influencing head, eye and postural stability
these reflexes work in conjunction with other reflexes, which are influenced by vestibular and vistual input for coordinated stability of the head, eye and posture
the ccr activates neck muscles in response to stretch to assist in the maintenance of head position
work with the
vestibulooculay reflex and
acting on the extraocular muscles
to assist clear vision with movement
TNR is integrate with
to achieve postural stability
the importance of the ... connections can be realized from response to artificial disturbances to the cervical afferents in asymptomatic individuals
Sectioning of the
anaesthetic injectios into the neck cause nystagmus
which is thought to stimulate muscle spindle afferent
Induce several disturbances in asymptomatic individuals including changes to eye and head position
alterations to body sway.
