Flashcards in chapter 13 - the senses Deck (19)
list the 5 sensory receptors
each type of receptor is most sensitive to a distinct type of stimulus
what are sensations
sensations are feelings resulting from sensory stimulation
general senses are associated with receptors in:
general senses are:
special senses have receptors in:
large, complex sensory organs of the head
the special senses are:
olfactory organs consist of:
receptors and supporting cells in the nasal cavity
taste receptors consist of:
taste cells and supporting cells
the five basic types of taste sensation
Sound perception is received by vibrations in?
Outer, middle and inner ear work together to receive vibrations which are perceived as sounds.
Middle ear is connected to throat via eustachian tubes
The inner ear gives sense of equilibrium.
The outer ear consists of?
External acoustic meatus (external auditory canal)
Eardrum (tympanic membrane)
The middle ear (tympanic cavity) contains?
Auditory ossicles (malleus, incus, stapes) and is connected to the throat via the auditory (eustachian) tube
The complex inner ear is important to establish the sense of?
It contains Chambers and tubes that form it’s bony labyrinth, which lies above and membranous labyrinth. The semicircular canal is a in equilibrium, whereas the cochlear functions in hearing.
The sense of equilibrium consists of static and dynamic equilibrium.
In static equilibrium, the position of the head is sensed while the head and body are still.
In dynamic equilibrium, motion is detected when the body and head move all rotate, aiding in balance.
What is the dominant sense
Vision. The sense of sight.
The eye has three distinct layers - outer layer
The outer layer is fibrous and anterior imposition, bulging forward to form the transparent cornea. The cornea and lens of each eye refract light waves to focus an image on the retina, which transmits visual perceptions to the brain.
The white coloured sclera makes up most of the outer layer.
The eye has three distinct layers - middle layer
The middle layer of the eye called the uvea, is vascular And includes the choroid coat, ciliary body, and iris.
The lens is held in position by many suspensory ligament’s behind the iris and pupil.
