Document Summary
Unit three study guide nrsc 2100: anatomical terms, posterior (caudal) v. anterior (rostral, ventral (stomach) (top) v. doral (back) (bottom, medial (middle) v. lateral (sides) Trochlear: eye movement (motor: v. trigeminal: jaw muscles, facial touch, and pain (both, vi. Glossopharyngeal: taste, muscles of the throat, pharynx, and larynx (both: x. vagus: internal organs (both, xi. Auditory system: sound properties, propagates through gases, liquids, and solids (metals, cycle: successive compression and rarefaction of medium, frequency (pitch): cycles/ second; hertz (hz, human audio range: 20 20,000 hz. Inner and outer hair cells embedded in deiter"s cells and rods of corti. Interaural time delay: time taken for sound to reach ear to ear: some neurons detect microsecond delay. Interaural intensity difference: can only detect 200 20,000 hz, vertical plane: precise shape of pinna provides slightly different echo times from sounds coming from vertical angles, central auditory pathway, 1. Superior olive (lateral meniscus) decussates here crossing of axons: 4.
