Sensory perception Flashcards
1
Q
What does hearing help with? (5)
A
- equilibrium
- orientation
- balance
- direction of gravity
- detection of vibrations
2
Q
What does the lateral line system help with? (2)
A
- detection of vibrations/water movements
- orientation to direction of disturbance, prey detection/predator avoidance
3
Q
How much faster does sound travel in water compared to air?
A
- 4.8x
- 330 vs 1500 m/s
4
Q
What are vibrations of molecules picked up by?
A
- inner ear
5
Q
What kind of transduction does the inner ear use?
A
- mechanico-electric
6
Q
What does the swim bladder do in herring and carp?
A
- connection to inner ear that amplifies perception of higher frequency sounds
7
Q
What does the swim bladder do in ostariphysans?
A
- connected to inner ear via weberian apparatus to improve hearing (like inner ear bone)
8
Q
What detects water movements on the lateral line? What are the water movements?
A
- mechanoreceptors (neuromasts)
- vibration/pressure
