Study Notes
- The auditory and equilibrium systems are two vital sensory systems in the human body.
- The auditory system is responsible for hearing and is primarily located in the temporal lobe of the brain, specifically in the auditory cortex.
- The ear consists of three parts: outer, middle, and inner.
- The outer ear, including the pinna and external auditory canal, is involved in collecting sound and channeling it inward.
- The middle ear, or tympanic cavity, is an air-filled cavity that transmits sound vibrations to the inner ear. It contains three bones: the malleus, incus, and stapes, which help to transfer sound.
- The inner ear, or bony labyrinth, is a complex structure that includes the organs of hearing and balance. It is filled with perilymph and contains the cochlea, home to the organ of Corti and the hair cells responsible for hearing.
- The cochlea works by converting sound vibrations into electrical impulses that are transmitted to the brain via the cochlear nerve.
- The equilibrium system is responsible for maintaining balance and is primarily located in the cerebellum. It includes the vestibule and semicircular canals, where receptor cells send information via the vestibular nerve regarding head position.
- The vestibule's maculae detect static equilibrium, while the semicircular canals detect dynamic equilibrium through the stimulation of hair cells by endolymph movement.
- The chemical senses, including taste and smell, are stimulated by chemicals in solution and are detected by olfactory receptors in the nasal cavity and gustatory cells in taste buds located primarily on the tongue.
- Taste buds have gustatory hairs and are stimulated by chemicals dissolved in saliva, while the olfactory system interprets smells in the cortex.
- Both the auditory and equilibrium systems, as well as the chemical senses, are functional at birth and are essential for survival.
