Where are the saccule and utricle located quizlet?
Where are the saccule and utricle located? Within the vestibule of the inner ear.
What is the inner ear region called that contains the utricle and saccule?
the vestibule
Within each structure, and filling only a fraction of the available space, is a corresponding portion of the membranous labyrinth: the vestibule contains the utricle and saccule, each semicircular canal its semicircular duct, and the cochlea its cochlear duct.
What is the function of the utricle and saccule quizlet?
– They are both organs for static equilibrium, which maintains the stability of the head and body when they are motionless or during linear (straight) movements. – Both the utricle and saccule have a small area of hair cells called the macula.
Are utricle and saccule involved in hearing?
The utricle and saccule are the two otolith organs in the vertebrate inner ear….Utricle (ear)

What does the macula in the utricle detect quizlet?
The smaller of the two membranous sacs in the vestibule of the inner ear; it contains a specialized mechanoreceptor, a maculae, for the detection of static equilibrium.
What are the tiny crystals found within the macula of the utricle called quizlet?
3 layers of macula: the bottom layer is made of sensory hair cells which are embedded in a gelatinous layer. top layer lie carbonate crystals called statoconia or otoliths.
What type of movement do the saccule and utricle respond to respectively?
Answer: They detect different directional movement because the saccules are oriented vertically, while the utricles are oriented horizontally.
What does the macula in the utricle detect?
The macula of the utricle is in a horizontal position and detects horizontal acceleration. The coordinated sensory perception of acceleration both vertically and horizontally along the vestibular nerve, allow for the perception of linear acceleration in any direction.
Where are the utricle and saccule located?
the inner ear
The utricle is a small membranous sac (part of the membranous labyrinth) and paired with the saccule lies within the vestibule of the inner ear. It has an important role in orientation and static balance, particularly in horizontal tilt.
Are the semicircular canals involved in hearing?
The bony labyrinth itself has three sections. 1) The cochlea is responsible for hearing, 2) the semicircular canals have function associated with balance, and 3) the vestibule which connects the two and contains two more balance and equilibrium related structures, the saccule and utricle.
What does the utricle do?
The utricle is a small membranous sac (part of the membranous labyrinth) and paired with the saccule lies within the vestibule of the inner ear. It has an important role in orientation and static balance, particularly in horizontal tilt.
