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.
