Question:
The macula situated in the utricle and saccule consists of hair cells and supporting cells. The tips of hair and cilium project into a thick gelatinous sheath called _____ membrane.
The macula situated in the utricle and saccule consists of hair cells and supporting cells. The tips of hair and cilium project into a thick gelatinous sheath called _____ membrane.
Show Hint
The macula of the utricle and saccule is covered by the otolithic membrane containing otoliths.
Updated On: Nov 12, 2026
- tectorial
- otolithic
- basilar
- Reissner's
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
The utricle and saccule each have a sensory patch called the macula, made of hair cells and supporting cells.
Step 2: The covering
The hair tips are embedded in a jelly-like layer with calcium carbonate crystals called otoliths. This layer is the otolithic membrane, and it moves with gravity and linear acceleration.
Step 3: Why the other options fail
The tectorial, basilar and Reissner's membranes belong to the cochlea.
Final Answer:
The gelatinous sheath is the otolithic membrane. \[ \boxed{\text{(B) }\text{otolithic}} \]
