     Anatomical Features of Human Ear   

    1. Pick up the Ear model. Locate each of the structures on your terminology sheet.
    2. Fill in the chart to help you summarize the information you learned.
    3. Carefully observe and Identify the anatomical features of the human ear indicated by numbers: Auricle, External Acoustic meatus, Pharyngotympanic tube, Vestibule, Semicircular canals, Tympanic membrane, Middle ear, Cochlea.
    Outer, middle, and inner ear models.

    Figure \(\PageIndex{1}\) is an anatomical model of the human ear with various parts labeled from 1 to 7. These labels identify key components of the ear: pinna, ear canal, eardrum, malleus, incus, stapes, cochlea, vestibule, semicircular canals, Eustachian tube, and outer ear. The detailed labeling supports understanding of the ear’s structure and auditory function. The numbers are used as prompts to fill Table\(\PageIndex{1}\).

    Carefully observe Figure \(\PageIndex{2}\) and Identify the anatomical features of the human ear indicated by numbers: Cochlea (uncoiled), Round window, Scala vestibuli, Scala tympani, Scala media, Spiral ganglion, Cochlear nerve (part of the vestibulocochlear nerve), Vestibular membrane, Basilar membrane, Tectorial membrane, Organ of Corti.
