Explanation / Answer

21.true - the temporary lobe contain the primary auditory cortex.

22.true - in making a saccade to the right of is imperative that the left lateral lateral rectus is activated and the right medial rectus is activated

23.true - the medial geniculate nucleus is part of auditory thalamus it relays information from sensors .

24.True - VPL (ventral posterolateral nucleus ) receive information from body and VPM ( ventral posteromedial nucleus) receive information from face.

25.false - influx of sodium ion is from Scala vestibule is not critical.

26.true - k+ ion stimulate glutamate release from astrocytes by activating voltage dependent calcium channel.

27.true - ventral posterior nucleus receive projection from vestibular nuclie. Which is also known as ( vpl - vpm)

28.true.- the basilar membrane displacement useful for high frequency sounds.

29.false - meissner corpuscles fuction is human sensory reception.

30.true - periaqueductal gray send descending pain modulation it is primary control center for descending axon.

31.true - vestibular system contribute to sensory information to cerebellum.
