36
Structure 11.
Outer Ear (Pinnae)
37
Pinnae | Function
Funnels sound waves Localises sounds vertically
38
Tympanic Membrane | Function
Identifies movement of air - Vibrations
39
Auditory Ossicles | Function
Transmits + amplifies signal to oval window (Inner ear is full of fluid, so amplification of the signal has to occur)
40
Oval + Round Windows | Functions
Separates the inner and middle ear
41
Eustachean Tube | Function
Pressure release
42
Proprioception
The body's awareness of other components (e.g. limbs)
43
Golgi Tendon
Detects changes in muscle tension
44
Muscle Spindle
Detects changes in muscle length
45

56
Rods
Dim light + peripheral vision receptors
57

Bright light + high resolution colour vision
58
Information From Balance Receptors Destination
Brain stem reflex centres
59
60
What Causes Motion Sickness
A mismatch between visual and vestibular inputs
61
How Are Gustatory Cells Stimulated?
By substances dissolved in solution | (Saliva)
62
Has 70% Of All Sensory Receptors
The Eye
63
Special Sense Not Fully Functional At Birth
Vision
64
Receptor For Static Equilibrium
Vestibule
65
Receptor Membranes of Gustatory Cells
Gustatory hairs
66
Volume Of Sound Is Detected By What
Greater movement of the basilar membrane resulting in greater deflection of the hair cells
67
Head Rotational Movements, and Linear Acceleration/Deceleration Is Signalled By The...
Vestibule
68
Lost Ability to Hear High Frequency Sounds Cause
Damage to the hair cells near the oval window in the cochlear duct
69
Why Is Night Vision Fuzzy and Indistinct?
The foveae are densely packed with cones, which struggle to work in dim light
