Impulses for the vestibular sense begin in theMultiple choice question.semicircular canal.temporal cortex.medulla.auditory nerve.

To answer this multiple-choice question regarding the vestibular sense, let's analyze each of the options provided:

1. Semicircular Canal: The semicircular canals are part of the inner ear and play a crucial role in detecting rotational movements and maintaining balance. They are directly involved in the vestibular system.

2. Temporal Cortex: The temporal cortex is involved in processing auditory information and aspects of memory and language, but it is not the origin point for impulses related to the vestibular sense.

3. Medulla: The medulla oblongata is involved in various autonomic functions and relays sensory information, but it does not directly generate the impulses for the vestibular sense.

4. Auditory Nerve: The auditory nerve transmits sound information from the cochlea to the brain, and while it is vital for hearing, it is not responsible for vestibular impulses.

Final Answer

The correct answer is semicircular canal. The impulses for the vestibular sense begin in the semicircular canals, which detect changes in head rotation and help maintain balance.
