(25 cards)
The blind spot of the eye is:
where only cones occur
where more rods than cones are found
where the optic nerve leaves the eye
why some people cannot see
where the maduca lutea is located
where the optic nerve leaves the eye
Which of the following structures of the eyeball contains photoreceptors?
choroid sclera retina iris cornea
retina
Which of the following statements describes a task that is accomplished using the intrinsic eye muscles?
changing the nshape of the lens for near vision
rolling your eyes after taking a ridiculously easy test
turning the auricle towards the source of the sound
changing the size of the pupil for light and dark conditions
inreasing or decreasing the amount of aqueous humor
rolling your eyes after taking a ridiculously easy test
During dark adaptation
the eyes can’t see
the sensitivity of the retina decreases
the cones are activated
the rate of rhodopsin breakdown is accelerated
rhodopsin accumulates in the rods
rhodopsin accumulates in the rods
The sensation of itch results from the stimulation of
lamellated corpuscles proprioceptors thermoreceptors free nerve endings corpuscles of touch
free nerve endings
Which of the following are found in the middle ear?
Qqq tympani bony labyrinth vestibule cochlea auditory ossicles
auditory ossicles
Cochlear implants are
A neuro-prosthetic device with an external component, a transducer and a intracochlear catheter for electrical signal conduction
A microscopic electronic chip placed in the round window of the cochlea
A surgical procedure to implant a replacement synthetic cochlear
A hearing aid with muliple transducers and a microphone for electrical signal conduction
A surgical procedure to implant a replacement synthetic tectorial membrane
A neuro-prosthetic device with an external component, a transducer and a intracochlear catheter for electrical signal conduction
Olfaction is related to emotional memory, this is because the sensory fibres are associated with the
limbic system pineal gland Frontal lobe somatory sensory cortex Occipital lobe
limbic system
The sense that tells us which muscles are contracted, the amount of tension in a joint, the position of the joints, and orientation of the head is called
nociception touch reception adaptation gustation proprioception
proprioception
There are two types of major functional categories of hearing loss, they are …
Conductive and sensorineural Conductive and congenital Sensorineural and genetic Sensorineural and adaptive Congenital and genetic
Conductive and sensorineural
The structure that regulates the amount of light entering the eye is the
lens aqueous humour iris cornea retina
iris
The cranial nerve associated with olfaction is
II IV V I X
I
The muscle responsible for changing the shape of the lens to improve near vision is the
ciliary muscle iris superior oblique muscle arrector pili muscle superior rectus mescle
ciliary muscle
When you sniff the air to detect or identify odours, you are
reducing adaptation of the olfactory sense
increasing the osm otic pressure on the olfactory mechanorecptors
forcing gases into solution
forcing air to the back of the throat toward the olfactory nerves
forcing air to the top of the nasal cavity where olfactory chemoreceptors are located
forcing air to the top of the nasal cavity where olfactory chemoreceptors are located
Hypermetrophia is a form of
refractive abnormality raised pressure index degeneration of the retina cataract formation Glaucoma
refractive abnormality
Photopigment in rods is called
chorophyll melanin rhodopsin retinal opsin
rhodopsin
Which of the following conditions is the most common, which can present with a significant speech impediment?
Cervical vertebral defects Stroke Asthma Laryngeal spasm Dental abscess
Stroke
The structure that carries tears from the lacrimal gland onto the surface of the eye is called the
lacrimal canal nasolacrimal duct lacrimal sac lacrimal duct auditory tube
lacrimal duct
Presbyopia is
Double vision
The loss of close vision, that progressively exacerbates with age
Long sightedness from childhood
The multiple focal spread at the back of ther retina caused by spherical deviation
Short sightedness
The loss of close vision, that progressively exacerbates with age
Glaucoma is frelated to the impaired drainage of
Vitreous humour Aqueous humour Tear duct atresia Lacrimal secretions CSF
Aqueous humour
The most common form of congenital hearing loss is …
Autosomal dominant genetic mutations
Syndromic hearing loss
External auditory atresia
Mitochondrial gene mutations
Autosomal recessive genetic mutations
Autosomal recessive genetic mutations
Lens opacity is a feature of …
Diabetic retinopathy Macular degeneration Refractive focal anomaly Glucoma Cataract development
Cataract development
Congenital atresia is
A malformation that forms a dead end in a canal that should be patent or an absent entrance
An extended growth within the basilar membrane
A missing limb or external appendage like the pinna of the ear
A missing or malformed nerve
An embolism formed in utero
A malformation that forms a dead end in a canal that should be patent or an absent entrance
Loss of speech or loss of tone in speech can occur because of damage to the following cranial nerve
Facial nerve Trochlear nerve Olfactory nerve Abducent nerve Oculomotor
Facial nerve
