Capitolo 17, Problema 5
The basic receptors in the internal ear are the
(a) Utricles
(b) Saccules
(c) Hair cells
(d) Supporting cells
(e) Ampullae
Guida verificata passo dopo passo1
Understand that the internal ear contains specialized sensory receptors responsible for detecting sound and balance.
Recognize that the basic sensory receptors in the internal ear are specialized cells that convert mechanical stimuli into nerve impulses.
Recall that hair cells are the primary sensory receptors in the internal ear, located within structures such as the cochlea and vestibular apparatus.
Note that utricles, saccules, and ampullae are parts of the vestibular system that contain hair cells but are not themselves the receptors.
Conclude that the correct answer is (c) Hair cells, as they are the fundamental receptor cells responsible for detecting auditory and balance stimuli.

Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Structure of the Internal Ear
The internal ear consists of the cochlea, vestibule, and semicircular canals. It houses sensory organs responsible for hearing and balance, including specialized receptor cells that detect sound vibrations and head movements.

Internal Anatomy
Hair Cells as Sensory Receptors
Hair cells are the primary sensory receptors in the internal ear. They have hair-like projections called stereocilia that convert mechanical stimuli from sound waves or head movements into electrical signals sent to the brain.

Role of Utricles, Saccules, and Ampullae
Utricles and saccules detect linear acceleration and gravity, while ampullae in semicircular canals detect rotational movements. These structures contain hair cells embedded in gelatinous material that respond to motion, aiding in balance and spatial orientation.
