CANS- Central Auditory Nervous System: Anatomy and Physiology fully solved 2024/2025

CANS- Central Auditory Nervous System: Anatomy and Physiology Nervous System - correct answer Brain and Spinal Cord Cerebrum - correct answer largest, most complex region, controls thought, learning, sensory information; diff. loves Cerebellum - correct answer Coordinates movement, posture, balance, muscle coordination Brainstem - correct answer Connects cerebrum with spinal cord, responsible for motor and automatic functions Cortex - correct answer Outermost layer of cerebrum -final processing of acoustic stimuli -folded, ridges & depressions Auditory Pathway in CNS - correct answer Major landmarks/stations (from the cochlea) -cochlear nucleus -superior olivary complex (major tract: lateral lemniscus) -inferior colliculus -Medial geniculate body (in thalamus) (tracts: auditory radiations -- deliver to auditory context) -Auditory Cortex (in superior temporal gyrus) Major Auditory Pathways in CNS - correct answer -some tracts ascend ipsilaterally, some contra laterally -some projections skip levels -minimum # of synapses to get from cochlea to primary auditory cortex:
