Hearing
What bone is middle ear inside of
Temporal bone
The anatomical name for the eyelid
Palpebral
The receptor which controls equilibrium
Vestibular apparatus
The process of receiving smells
Olfaction
The process of taste
Gustation
The region of the ear which uses the bony system to amplify sound vibrations
Middle ear
What is the condition where the light rays which are coming in from close objects are focused behind the retina
Hyperopia (farsightedness)
The small elevation within each ampulla
Crista
The condition hyposmia
Having a reduced ability to smell
The life span of each gustatory epithelial cell
10 days
What are the two divisions which the inner ear consists of
Outer bony labyrinth and inner membranous labyrinth
What occurs when a stimuli causes the parasympathetic fibres of the ocular motors to trigger the sphincter papilla
the circular muscles of the iris contract making everything dimmer
What each crista within dynamic equilibrium contains.
Hair cells and supporting cells covered with gelatinous materials
The three kinds of cells within Olfaction epithelium
Olfaction epithelium, basal cell, supporting cells
The 5 primary tastes
Sweet, sour, bitter, salty and umami (savoury)
The three auditory ossicles in the air filled cavity of the middle ear
Stapes (stirrup), Incus (anvil), Malleus (hammer)
The name of the middle layer tunic and the 3 things it contains
Vascular Tunic, containing the choroid, ciliary body and the iris
What is the name of the columnar supporting cells that are scattered among the hair cells in the cupula
Ololithic membrane
Name 3 things that epithelial cells provide to olfaction
Physical, support, nourishment, electrical insulation for sensory neuron's, help detoxify chemicals that contact olfaction epithelium
What protrudes form gustatory epithelial cells from the external surface through the taste pore?
Gustatory microvill/gustatory hairs
The part of the ear that is a flap of elastic cartilage covered with skin, and contains ceruminous glands and its region
Auricle (pinna) within the external ear
What the fluid within the eye cavity is needed for, using the production of aqueous humor
The fluid inflates the walls of the eyeball (maintaining constant intraocular pressure),and supports the vitreous body
The two types of equilibrium and what they are each controlled by
Static equilibrium - is controlled by the sensory hairs within the macula of utricle and saccle. Dynamic equilibrium – is controlled by sensory hairs within the ampulla of semicircular canals
The process of olfactory sensory pathways
The pathways adapt rapidly by decreasing activity by 50% within the first second of a scent being smelt, but after 1-2 minutes it has accommodated
Name one of the three cells that taste buds are composed of, and explain what they do
Gustatory receptors cells, which have gustatory hairs projecting to the external surface through the taste pore. Supporting cells which surround and support receptor cells. Basal cells, which multiply and differentiate.
