Visual System
The colored part of the eye that changes shape allowing pupil to constrict.
What is the Iris?
Sound waves beat on this structure with a frequency and altitude consistent with the sound that made it. Also known as the ear drum.
What is the Tympanic Membrane?
Damage to these (general) area does not result in dramatic symptoms because they are bilateral.
What are Motor Command Givers?
This motor planning area is internally driven.
What is the Supplementary Motor Area (SMA)?
What are cones?
This structure helps relieve pressure in the middle ear.
What is the Eustachian tube?
These structures have a receptor known as Crista Ampularis and can detect angular acceleration.
What are Semicircular Canals?
This cranial nerve innervates the stylopharangeus muscle.
What is CN 9?
This area of the cortex helps us visual recognize an object and has to do with memory.
What is the Temporal Visual Assoc. Cortex?
This area of the cortex allows us to visually discriminate basic characteristics of objects.
What is the Primary Visual Cortex?
This structure is the sensory receptor for the auditory system that moves when a sound wave enters into the cochlea.
What is the Organ of Corti?
The inner component of semicircular canals is the membranous labyrinth filled with this fluid that has high K+ and low Na+.
What is endolymph?
Damage to this motor nuclei can result in autonomic dysfunction, possible heart rhythm irregularities, constipation, and diminished gut motility.
What is the Dorsal Motor Nuclei of CN 10?
This area helps us form a spatially accurate map of the environment in order to act on an object.
What is the Parietal Visual Assoc. Cortex?
This is damage to the rostral occipital cortex resulting is loss of peripheral vision on the opposite side.
This interferes with transition of sound from the outer ear to the inner ear and can occur when there is damage to the middle ear, tympanic membrane, or ear canal.
What is Conduction Deafness?
This Otolithic Organ is most helpful for sensing straight forward and back head movement because it is positioned horizontally.
What is the Utricle?
This sensory nucleus is responsible for taste of CN 7, 9, and 10.
What is the Solitary Nucleus?
In order to say the name of an object with correct articulation and intonation we see we must go to this area of the cortex.
What is Broca's area?
This is damage to the optic chiasm resulting in loss of vision in both temporal visual fields. Also known as tunnel vision.
When stereocilia embedded in the tectorial membrane bend towards this structure, an action potential is created.
What is the kinocilium?
This occurs when otoconia (crystalized calcium) from the utricle are displaced into the semicircular canal causing deflexion of the cupula (gelatinous membrane of SC).
Begnin Paroxysmal Positional Vertigo
This nerve provides taste from posterior 1/3 of tongue.
What is CN 9?
In order to recognize/comprehend the name of an object we must go to this area.
What is Wernicke's Area?
