Document Summary
Hair cells long cell that has hair on the top. Outer hair cells (lateral) sensory cells elongated in shape with small hairs (cilia) attached to the top and embedded into the tectorial membrane, which covers the. Organ of corti: cilia are embedded into the tectorial membrane, tectorial membrane is kind of part of the organ of corti. Jelly like: 3 rows of 13,000 out hair cells. Kinocilium longest hair: oae tests outer hair cell function. Inner hair cells (medial) sensory cells elongated in shape with cilia in close proximity to the tectorial membrane: 1 row of 3,500 inner hair cells. Vibration of the stapes oval window fluid motion in cochlea membranous labyrinth moves. Sensory cells stimulated neural impulses to cn viii auditory cortex (need to know this order) which of the following is the correct physiologic order? (could be a test question) Traveling wave wavelike motion of the basilar membrane (membranous labyrinth moving) that.
