PSYC 207 Study Guide - Final Guide: Public Knowledge, Proprioception, Frontal Lobe
Document Summary
Can tell a lot about a patient in case of emergencies. No time to run extensive tests in emergencies. Cranial nerve testing: olfactory (scent, optic (vision, occulomotor (testing eye movement, trochlear (eye movement, trigeminal (sensations on face, touch, abducens (eye movement, facial (facial expressions) 8: glassopharyngeal (voice, vagus (internal organs, accessory (neck movement, hypoglossal (tongue movement) Multiple tracts control various movements: important for voluntary movement, other pathways may take over when original tract is damaged but will not be as good as original. Somatosensory pathway: touch, vibration, proprioception (knowing where body is in space, pain, temperature. Information go from sensory neuron, to interneuron in spinal cord, to motor neuron. Damage to upper motor neurons = bigger reflexes: lower motor neurons = no reflexes. Snouting: extending toes when tickled under foot (should contract, puckering up when touched on upper lip (shouldn"t happen) These reflexes exist in young infants, due to underdeveloped frontal cortex.
