Does spinal cord affect reflexes?

The spinal cord transmits nerve impulses to and from the brain and mediates several important reflexes. It also coordinates more complex motor sequences (e.g. those required for walking).

How does spinal cord injury affect swallowing?

What are examples of spinal reflexes?

Spinal reflexes include the stretch reflex, the Golgi tendon reflex, the crossed extensor reflex, and the withdrawal reflex.

What is spinal reflex excitability?

Increased spinal reflex excitability is associated with enhanced central activation during voluntary lengthening contractions in human spinal cord injury. J Neurophysiol.

Can spinal problems cause difficulty swallowing?

Cervical spine disorders which can cause swallowing difficulties (cervicogenic dysphagia; CD) are: chronic multisegmental/MS dysfunction (dysfunction=functional blockade) of the facet joints, changes in physiological curvature of the cervical spine, degenerative changes (anterior osteophytes, anterior disc herniation.

Is it possible to suppress the gag reflex?

For most people, a continuation of the gag reflex can be suppressed with varying degrees of success once the initial gag happens, and with things like brushing the back of one’s tongue, holding it out for the 10 seconds needed without throwing up isn’t normally too difficult [1].

What cranial nerves are involved in the gag reflex?

The gag reflex is an example of a cranial nerve reflex which is mediated by the glosopharyngeal (CN IX) and vagus (CN X) nerves. Afferent sensory information is conveyed by cutaneous stimulation of Aδ and C fibres on the caudal base of the tongue and/or the caudal soft palate.
