Middle Ear
Tympanic Cavity
Lobule
Earlobe
The pathway through which sounds pass to the middle ear:
- External Aucoustic Media
- Tympanic Membrane
- Malleus
- Incus
- Stapes
- Oval Window
The frequency of soundwaves
Determines the pitch of sound
In the inner ear
The membranous labyrinth lies inside the bony labyrinth
The spiral organ
is situated in the cochlear duct
Accomadation
The adjustment in the eye required for close vision
Refraction
Bending of light rays
Ciliary
Muscles that contract causing tightening of the suspensory ligaments for near vision
Lens
The structure in the eye that changes its refractory power
Iris
The visible colour part of the eye
Rods
Light sensitive cells that convert light rays into nerve impulses
Retina
Innermost layer of the eyeball adapted for stimulation by light rays
Opthalmic
Branch of the carotid artery that supplies blood to the eye
Sclera
Layer of the eyeball that provides attachment for the extrinsic ocular muscles
Extrinsic
Group of muscles that move the eyeball
The structures through which light waves pass when entering the eye
- Cornea
- Pupil
- Anterior chamber
- Lens
- Virteous body
- Retina
Nasolacrimal duct
Drains tears into the nose
Lacrimal duct
Drains that carry tears to the eyes
Eyebrow
Protects the eyeball from sweat and dust
Lacrimal gland
An almond-shaped structure located within the frontal bone
Cornea
Fine transparent fibres that lines the eyelids
Lysozme
An antibacterial enzyme in tears
Meibomian gland
Lies within the tarsal plates
Eyelid
Associated with the orbicularis oculi and levator palpebrae muscles
The olfactory nerves are
The first pair of cranial nerves
Smell stimulates
Chemoreceptors
Chemoreceptors
are found in the roof of the nose
Nerve impulse involved in smell pass to
The olfactory bulb and then to olfactory tract
Perception of smell occurs in
The temporal lobe of the cerebral cortex
The olfactory tract carries impulses associated with
Smell
Both olfactory receptors and taste buds are
Chemoreceptors
A somatic sense would be associated with
Pain
Taste buds can be found:
- In the lining of the mouth
- On the soft palate
- On the tongue
- In the epiglottis

Pharyngotympanic tube
Lobe of the cerebral cortex in which the visual area is located
Occipital
Movement of the eyeballs for near vision
Convergence
Difficulty in accommodation for near vision that accompanys the ageing process
Presbyopia
Part of the cochlear that is connected to the round window
Scala Tympani
Adjustments in the eye required for close vision
Accommodation
Sensory receptors in muscles and joints

Hearing impairment that accompanyies the ageing process
Detachment
Painless condition associated with a hole or tear in the retina
Retinopathy
Visual impairment associated with diabetes mellitus
