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.
