Study Notes
Eye Anatomy
- Retina: Innermost layer of the eye responsible for light detection.
- Aqueous and Vitreous Humors: Fluids that fill the eyeball, maintaining its shape.
- Tympanic Membrane: Also known as the eardrum, equalizes pressure through the Eustachian tube.
- Optic Nerve: Transmits visual signals from the retina to the brain's occipital lobe.
- Cones: Retina's sensory cells that detect bright light and enable color vision.
Sense of Taste
- Umami: One of the five basic tastes, alongside sweet, salty, sour, and bitter.
- Taste Buds: Located in tiny bumps called Papillae on the tongue, responsible for taste sensation.
- Taste Sensation: About 75% to 90% of taste is influenced by smell.
Auditory System
- Auditory Canal: Tubular structure connecting outer ear to the eardrum.
- Vestibule: Inner ear chamber containing three semicircular canals, important for balance.
- Amusia: Condition characterized by singing off-key; linked to auditory processing.
Ear Health and Conditions
- Earwax (Cerumen): Secreted by ceruminous glands, protects against bacteria and debris.
- Labyrinthitis: Clinical term for inner ear infections.
- Tinnitus: Ringing sound in the ear; dizziness is not the primary cause.
- Rhinitis: Common cold is a frequent cause of nasal inflammation and blockage.
Nasal and Olfactory Function
- Histamines: Molecules that cause nasal congestion and irritation reactions.
- Olfactory Region: Tiny area at the top of each nasal cavity containing smell sensors.
- Olfactory Nerve: Pathway transmitting smell signals from the nasal cavity to the brain.
Other Notable Structures
- Lacrimal Glands: Located above each eye, responsible for tear production.
- Auricle: Irregularly shaped outer part of the ear crucial for sound collection.
