Chapter 17, Problem 11
Receptors in the saccule and utricle provide sensations of
(a) Angular acceleration
(b) Hearing
(c) Vibration
(d) Gravity and linear acceleration and deceleration
Verified step by step guidance1
Step 1: Understand the function of the saccule and utricle, which are parts of the vestibular system located in the inner ear.
Step 2: Recognize that the saccule and utricle contain specialized sensory receptors called maculae that detect changes in head position relative to gravity.
Step 3: Know that these receptors respond to linear acceleration and deceleration, as well as the pull of gravity, helping maintain balance and spatial orientation.
Step 4: Differentiate these sensations from angular acceleration, which is detected by the semicircular canals, and from hearing and vibration, which are detected by the cochlea and other structures.
Step 5: Conclude that the correct sensation provided by the saccule and utricle is related to gravity and linear acceleration and deceleration.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Saccule and Utricle Function
The saccule and utricle are otolith organs in the vestibular system that detect linear acceleration and head position relative to gravity. They contain hair cells embedded in a gelatinous layer with otoliths that shift with movement, stimulating the receptors to provide sensory input about balance and spatial orientation.

Functional Groups
Types of Acceleration Sensation
Angular acceleration refers to rotational movement detected by semicircular canals, while linear acceleration involves straight-line movement sensed by the saccule and utricle. Understanding the distinction helps identify which receptors respond to specific motion types.

Vestibular vs Auditory Sensations
Hearing and vibration are detected by the cochlea and other auditory structures, not the saccule or utricle. Differentiating vestibular sensations (balance and acceleration) from auditory sensations is essential to correctly attribute sensory functions to the appropriate receptors.
