Vision
2 types of photoreceptors
Rods and Cones
Sound is
what we experience when we hear something
pressure changes in air or other medium
the olfaction sense is a _________ sense
chemical
____ and smell interact to produce "flavour"
Taste
Registers body position and movement
Light enters the eye through
The cornea
The three psychological characteristics of sound are
Amplitude/loudness
Frequency/Pitch
Complexity/Timbre
the olfactory sense is the only sense in which
the nerves go directly to the brain
We have 5 taste receptors and a possible 6th
Sour, Sweet, Salty, Bitter and Umami
Possibly fattiness
Where are the vestibular sacs and vestibular rings located
the inner ear
You cannot see anything at your blind spot because
there are no receptors in this area
The outer ear consists of
The pinna, auditory canal and tympanic membrane (eardrum)
neurogenesis in the olfactory system means that
new neurons are created (approximately every 5-7 weeks)
Touch is processed by
The somatosensory system
Which sense works alongside the vestibular system to play a key role in balance
vision
What is the role of Bipolar cells
receive information from the retinal cells and distribute information to the ganglion cells
The ossicles consist of the
malleus, incus, stapes
For the olfactory sense, transduction occurs in the...
olfactory epithelium where the olfactory receptors reside
Touch is a mix of which three qualities
pressure, temperature and pain
The vestibular system reports to
the cerebellum
How does light reflection affect our perception of colour?
Objects that reflect light appear brighter, and objects that absorb most of the light appear darker.
place theory of hearing proposes that
different areas of the basilar membrane respond to different frequencies
Many animal species communicate through scent messages known as what?
Pheromones
Name 2 or more of the types of skin receptors
Merkel cells / Merkel's disk, detect Steady pressure
Tactile corpuscles / Meissner's corpuscles - light touch
Krause's end bulb - Detect cold
Pacinian corpuscles, detect vibration
Free nerve endings - pain, temperature
The Vestibulo–ocular reflex is
an involuntary reflex that stabilizes the visual field and retinal image during head motion - by producing eye movements in a counter direction
Helps you to see clearly even when , eg running or riding a bike on a bumpy track
