Patellar (stretch reflex) monosynaptic Purpose: Procedure: Autonomic or somatic? Cranial or spinal? Normal response: Abnormal response: |
Purpose: test peripheral nerve and ventral horn (L2-L4) Procedure:strike patellar ligament Autonomic or somatic? somatic Cranial or spinal? spinal Normal response: knee extension (ipsilateral) Abnormal response: no knee extension or exaggerated extension |
|
|
Achilles tendon (stretch reflex) monosynaptic Purpose: Procedure: Autonomic or somatic? Cranial or spinal? Normal response: Abnormal response: |
Purpose: test peripheral nerve and ventral horn (S1-S2) Procedure: strike Achilles tendon Autonomic or somatic? somatic Cranial or spinal? spinal Normal response: plantar flexion (ipsilateral) Abnormal response: no planter flexion or exaggerated flexion |
|
|
Plantar (superficial cord reflex) polysynaptic Purpose: Procedure: Autonomic or somatic? Cranial or spinal? Normal response: Abnormal response: |
Purpose: test L4-S2 nerves and corticospinal tract (upper-motor pathways and cord-level reflex) Procedure: stimulate cutaneous receptors on sole of foot (by stroking lateral border of subject's sole with metal end of reflex hammer starting at heel and continuing toward big toe) Autonomic or somatic? somatic Cranial or spinal? spinal but brain advised Normal response: downward flexion of toes (ipsilateral) Abnormal response: Babinski's sign- big toe hyperextension, other toes abduct (normal in infants under 2 years due to incomplete mylination) |
|
|
Crossed extensor Purpose: Procedure: Autonomic or somatic? Cranial or spinal? Normal response: Abnormal response: |
Purpose: tests for damage to C5-C8 spinal cord and pathways to cerebellum Procedure: relax arms on table, prick arm (finger)/sharp object Autonomic or somatic? somatic Cranial or spinal? spinal- but brain advised Normal response: pricked arm withdraws, opposite arm extends (contralateral) Abnormal response: no response by 1 or both arms |
|
|
Corneal Purpose: Procedure: Autonomic or somatic? Cranial or spinal? Normal response: Abnormal response: |
Purpose: test cranial nerves V (trigeminal) and VII, and brainstem Procedure: blow air or touch subject's eye Autonomic or somatic? somatic Cranial or spinal? cranial Normal response: close eye Abnormal response: doesn't close eye |
|
|
Pupillary Purpose: Procedure: Autonomic or somatic? Cranial or spinal? Normal response: Abnormal response: |
Purpose: test cranial nerves II (optic) and III (oculomotor), brainstem Procedure: dim room, shine light into eyes, may have subject shield either eye with hand vertically between Autonomic or somatic? autonomic (parasympathetic) Cranial or spinal? cranial Normal response: pupils constrict (consensual) Abnormal response: no constriction |
