Neuro Exam 2

Conveys info about light touch and conscious proprioception

DCML

Conveys discriminative info about nociception and temperature

Spinothalamic

medial tracts that arise in brainstem

reticulospinal, medial and lateral vestibulospinal

Medial tracts that arise in cortex

Medial corticospinal

Facilitates bilaterl LMN innervating postural and proximal limb movements; manages synergies

Reticulospinal

Signals to muscles of head and neck; mainly in cervical region

Medial vestibulospinal

Responds to gravity info, helps with COG for rest of body except head and neck

Lateral vestibulospinal

Voluntary control to neck, shoulder, and trunk muscles

Medial corticospinal

Primary body mover arising in pre-motor areas

Lateral corticospinal

Inhibition of antagonist muscles during agonist contraction

Reciprocal inhibition

fine motor output by inhibit agonist and synergists

Recurrent inhibition
