Touch + Pain
This cortex receives touch information from the contralateral side of the body.
What is the primary somatosensory cortex?
What is the extrapyramidal tract?
This process causes hair cells to convert sound waves into electrical signals.
What is mechanotransduction.
These types of taste are conveyed by ion channels on taste receptor cells.
What are salty (Na+) and sour (H+)
This visual problem is characterized by the focal point falling behind the retina due to the eyeball being too short.
What is hyperopia (farsightedness)
These free nerve endings respond to stimuli relating to pain.
What are nociceptors?
This structure controls the initiation and ending of movement.
What is the basal ganglia?
This structure detects rotation and angular acceleration.
What is the ampulla?
These papillae are characterized by having no taste buds.
What are filiform papillae?
This happens to photoreceptors in the light.
What is hyperpolarization due to K+ efflux
These fibers have large myelinated axons and are used for proprioception.
What are A-alpha fibers?
These sensory receptors involved in sensory feedback detect changes in muscle length.
What are muscle spindles?
What is cochlear tonotopy?
This structure is responsible for detecting specific odorants.
What are olfactory glomeruli?
This category of fibers cross over at the optic chiasm.
What are nasal retinal fibers?
This pathway involves deccusation in the medulla.
What is the dorsal column pathway.
This muscle (1) is contracted during pain withdrawal reflex, and the other (2) is relaxed during pain withdrawal reflex.
1. flexor muscles
2. extensor muscles
This structure is the main sound localization area.
What is the superior olive?
This phenomena is characterized by olfactory hallucinations.
What is phantosmia?
These retinal ganglion layers process the details of an object (ex. shape, size, and color)
What are parvocellular layers?
These ion channels function as temperature sensors.
What are TRP channels?
These neurons use acetylcholine as their primary neurotransmitter.
This post-cortex pathway identifies what the sound is.
What is the ventral stream?
This cranial nerve carries information to the brain from the anterior 2/3 of the tongue
What is the facial nerve/CN VII
These bipolar cells are depolarized by glutamate.
What are off-center bipolar cells?
