Actions involving stimulation of a motor neuron by a sensory neuron in the spinal cord without involvement of the brain are called

reflexes

shoulder abduction

a classic sign of an acute burner is muscle weakness in actions involving

shoulder abduction and external rotation

an acute process in which the nucleus pulposus herniates through the posterior annulus, resulting in signs and symptoms of cord or nerve root compression is termed

soft-disk disease

In an injury involving the spinal cord, a transient loss of somatic and autonomic reflex activity below the level of neurological damage is called

spinal shock

the dermatome for C3 is the

supraclavicular fossa

which of the following characteristics would suggest a cervical sprain rather than strain

symptoms that persists for several days

true

trie of false? fractures and dislocations commonly occur at the 4th, 5th, and 6th cervical vertebrae

true

true or false? chronic burners are characterized by episodes that may not produce areas of numbness

true

axial loading of the cervical spine occurs when the neck is in a position of

flexion

spinal stenosis
