A
  1. Semicircular Canals
  2. Vestibular
  3. Cochlea
27
Q

When 2 layers and 3 parts are formed together it makes what 6 structures?

A

Membranous : semicircular canal, cochlea, vestibulae

Bony semicircular canals, cochlea, vestibulae

28
Q

What nerve connects with the membranous cochlea ONLY?

A

Cochlea nerve

29
Q

What does the Membraneous cochlea include?

A
  • Scala vestibulae ( perilymph )
  • scala media ( endolymph)
  • Scala Tympani ( Perilymph)
30
Q

The tectorial membrane, hair cells, & Basilar membrane are structures of ___?

A

Spiral Organ

31
Q

What 2 structures connect with the cochlear nerve ONLY

A
  • Spiral organ ;Membranous cochlea
32
Q

What is the base of the cochlea ?

A

High frequency

33
Q

What is the Apex of the cochlea ?

A

Low Frenquency

34
Q

Where is the cochlea located?

A

Superior Temporal Gyrus

35
Q

What is the process of the spiral organ?

A
  • basilar membrane (vibration) bends hair cells and generates action potential
  • action potential goes to ( cochlear Nerve) and travels to the cranial nerve and brain cortex
36
Q

What are the two parts of the vestibulae?

  1. Utricle

2. Saccule

37
Q

What part of the vestibulae connects to the semicircular canals ?

A

U.S

38
Q

What part of the vestibulae connect to the cochlea?

A

-Saccule

C.S.

39
Q

The Utricle & Saccule both travel through the _____ Nerve ?

A

Vestibular Nerve ONLY

40
Q

What is within the utricle and saccule?

A

Maculae

41
Q

What connects with the vestibular nerve?

A

Maculae

42
Q

What is within the endolymph and right angle to each other ?

A

Maculae

43
Q

What is the sandwich structure of the Maculae?

A
  1. Otolithic membrane
  2. Hair cells
  3. Basilar Membrane
44
Q

What is the function of the Maculae?

A
  • Static equilibrium receptor region

2D movement ( no rotation

45
Q

A

Vestibular nerve

47
Q

Semicircular canals and the vestibule go to what nerve ONLY?

A

Vestibular nerve

48
Q

What are three pairs of the semicircular canal and the plane that correlates with each?

A
  1. Anterior (Sagittal plane)
  2. Lateral (Transverse plane )
  3. Posterior (Frontal plane)
49
Q

Where is the ampulla located ?

A
  1. Gelatinous Cup (Cupula)
  2. Hair Cells
  3. Basilar membrane
52
Q

Cochlear, Vestibule and Crista ampullaris all generate ?

A

Action Potential

53
Q

What creates static equilibrium?

A

Vestibule

54
Q

What generates Dynamic equilibrium ?

A

Semicircular Canals

55
Q

How does action potential travel through semicircular canals

A
  • angular head position changes gelatinous cup , then bends hair fibers to generate action potential
  • actions potential transmits to ( vestibular nerve) and is sent to to cranial nerve 8 (vII) TO BRAIN CORTEX
