Auditory System
What is the middle ear?
This part of the ear is responsible for amplifying sound waves.
What is the gustatory system?
This system is responsible for the sensations and perceptions of taste.
what is the pupil?
This part of the eye regulates how much light enters by changing size.
What is the parietal lobe (somatosensory cortex)?
The brain region responsible for processing touch information is this lobe of the cortex.
What is the olfactory epithelium?
Smell is detected by receptors located in this thin layer of cells in the nasal cavity.
What is the temporal lobe?
This part of the brain processes auditory information.
What are sweet, salty, sour, bitter, and umami? (Any three correct)
Taste buds detect five primary tastes — name three.
What are cones?
These light-sensitive cells in the retina are responsible for colour vision.
What is phantom limb pain?
This condition occurs when amputees feel pain or sensations in a limb that’s no longer there.
What are cilia?
These tiny hairlike projections on sensory receptors bind to airborne molecules to trigger smell perception.
What are the ossicles (malleus, incus, and stapes)?
These three tiny bones in the middle ear amplify sound vibrations
What is multimodal integration?
Taste and smell often work together through this process that combines input from multiple senses.
What is perceptual constancy?
This term describes the brain’s ability to perceive objects as having constant shape, size, and colour despite changes in perspective.
What is chronic pain?
This type of pain lasts for extended periods, often continuing after the injury has healed, and can involve changes in the nervous system.
What is the olfactory bulb?
This brain structure, located at the base of the frontal lobes, processes smell information.
What are the semicircular canals?
The vestibular system helps maintain balance through these three fluid-filled structures in the inner ear.
What are gustatory receptor cells (or taste receptor cells)?
Each taste bud contains clusters of these specialized receptor cells that send signals to the brain about different taste qualities.
What is the optic chiasm?
The point at which optic nerves cross over to opposite sides of the brain is called this.
What are endorphins?
The brain can reduce pain perception by releasing these natural painkillers.
What is synesthesia?
When one sense involuntarily triggers another — like “seeing” colours when hearing sounds — it’s called this.
What is the inferior colliculus?
This midbrain structure helps determine the location of sounds in space.
What are papillae?
These small bumps on the tongue contain the taste buds that let us detect different flavours.
What is the fovea?
This part of the retina contains only cones and provides our sharpest vision, especially when we focus on fine detail.
What is the two-point threshold?
This term describes our ability to tell two nearby points on the skin apart.
What is the olfactory bulb?
This structure on the underside of the frontal lobes receives signals from the nose and is the brain’s main center for processing smell.
