    Study Notes

    Classification of Senses

    • Hearing is a mechanoreceptor.
    • Sight is classified as a photoreceptor.
    • Golgi tendon receptors function as proprioceptors.
    • Free nerve endings in the skin primarily respond to pain.
    • General sense organs are concentrated in the skin.

    Anatomy of the Eye

    • The white part of the eye is known as the sclera.
    • Conjunctiva is a mucous membrane covering parts of the eye.
    • The colored part of the eye is the iris.
    • The cornea is the clear front portion of the sclera.
    • The pupil allows light to enter the eye.
    • The choroid layer prevents scattering of incoming light rays.
    • The retina is the innermost layer of the eye.

    Photoreceptors in the Eye

    • Rods enable vision in dim light conditions.
    • Cones are part of the retinal layer and detect red, green, and blue colors.
    • The fovea centralis has the highest concentration of cones.
    • The "blind spot," or optic disc, is where no photoreceptors are present.

    Eye Components

    • Vitreous humor is located in the posterior chamber of the eye.
    • The external ear consists of the auricle (or pinna).
    • Eardrum is also referred to as the tympanic membrane.

    Middle and Inner Ear Structure

    • The sequence of ossicles from eardrum to inner ear: malleus, incus, stapes.
    • Tympanic membrane rests against the incus in the middle ear.
    • The oval window separates the middle ear from the inner ear.
    • The inner ear features the vestibule, semicircular canals, and endolymph.

    Fluids in the Ear

    • Perilymph is found within the bony labyrinth.
    • Endolymph is found inside the cochlea and semicircular canals.

    Balance and Hearing

    • The sense of balance is classified as a mechanoreceptor.
    • Balance is primarily associated with the semicircular canals and vestibule.
    • The organ of Corti is the specific organ of hearing.

    Taste and Smell

    • Taste is classified as a chemoreceptor; gustatory cells are responsible for taste sensations.
    • The four primary taste sensations are sweet, salty, bitter, and sour.
    • Smell, another chemoreceptor, plays a role in taste as well.
    • Olfactory receptors are sensitive and can adapt easily, responding to chemicals in water.
    • The olfactory tract passes through the limbic system, linking smell to vivid memories.

    Sensory Limitations

    • Taste and smell do not respond to four primary stimuli simultaneously.
    • Equilibrium is not sensed by general sense organs.
    • Smell, taste, and equilibrium sensations are not detected by special sense organs.
    • General sense organs are not limited to localized areas.

    Functional Characteristics of Sense Organs

    • All sense organs must detect a stimulus and changes in stimulus intensity.
