Q

True or False: Movement of head in one axis sets of flow of fluid in semicircular canal that is on the same plane, bending stereo cilia in that particular ampulla + signaling brain that the head moved

Q

What do the utricle and saccule each contain?

A

otolithic membrane that lags slightly when the head moves, causing bending of nearby hair cells

16
Q

What papillae are towards the front of the tongue?

A

fungiform papillae

17
Q

What do different types of papillae detect differently?

A

detect diff kinds of taste more strongly

18
Q

What are the fine fibers that extend from taste receptor cells into a tiny pore?

A

microvilli

19
Q

What are the substances that can be tasted?

A

tastants

20
Q

What is the pathway of taste (starts with papillae)?

A

papillae –> taste bud –> taste cells (microvilli come out of taste cells)

21
Q

How are salty tastes sensed?

A

ionotropic receptors; Na+ going through sodium ion channels –> depolarization –> Ca+2 enters –> ntrans released

22
Q

How are sour tastes sensed?

A

ionotropic receptors; H+ released from acids

23
Q

How are sweet tastes sensed?

A

metabotropic receptors

24
Q

T1R2 and T1R3 receptors are for which taste?

A

sweet

25
Q

How are bitter tastes sensed?

A

metabotropic receptors

26
Q

T2R receptor family is for which taste?

A

bitter

27
Q

Which receptors combine to form umami flavor?

A

T1R1 and T1R3; metabotropic glutamate receptors

28
Q

What is the system that detects taste?

A

gustatory system
