Vision
This part of the eye focuses light onto the retina.
What is the lens?
This membrane vibrates when sound waves enter the ear.
What is the tympanic membrane?
Another name for the the tympanic membrane is ___.
These structures in the inner ear detect rotational movement.
What are the semicircular canals?
This structure transmits smell signals to the brain.
What is the olfactory bulb?
This type of receptor detects stretch in muscles.
(Based on modality)
These photoreceptors allow you to see in low-light conditions.
What are rods?
This inner ear structure converts sound waves into nerve impulses.
What is the cochlea?
These small calcium carbonate crystals help detect head position.
What are otoliths?
This type receptor detects odorant molecules.
What are chemoreceptors?
Receptors classified by this criterion are categorized as exteroceptors, interoceptors, and proprioceptors.
What is location?
This part of the retina provides the sharpest vision due to a high density of cones.
What is the fovea centralis?
These three small bones amplify sound waves in the middle ear.
What are the auditory ossicles?
(malleus, incus, stapes)
Fluid buildup in the inner ear that causes dizziness is called this.
What is endolymph?
What is the cribiform plate?
This type of receptor structure is found in free nerve endings.
What are unencapsulated nerve endings?
Damage to this cranial nerve can result in loss of vision.
What is the optic nerve?
(Cranial nerve II)
This part of the cochlea detects high-pitched sounds.
What is the base?
This structure detects linear acceleration and head tilt.
What is the vestibule?
Loss of smell after a head injury is often due to damage to this structure.
What is the olfactory nerve?
Sensory receptors that detect stimuli inside the body are called this.
What are interoceptors?
This term describes the adjustment of the lens shape to focus on near or far objects.
What is accomodation?
This cranial nerve transmits auditory information to the brain.
What is the vestibulocochlear nerve?
(Cranial Nerve VIII)
This branch of cranial nerve VIII transmits equilibrium information to the brain.
What is the vestibular branch?
Odorant molecules bind to receptors located here.
What is the olfactory epithelium?
These SPECIFIC mechanoreceptors detect pressure and are deep in the skin.
What are Pacinian corpuscles?
