|Lab:||5th floor, Radiopoetro|
|Pre-test:||5 questions, multiple-choice.|
|Post-test:||10 questions, multiple-choice.|
|Lab Report:||One report per tutorial group:
- Several questions about the tracts: which ones carry proprioception, temperature, fine and dull touch, auditory/vestibular, etc.
- Several questions about a combination of hearing test results and what they mean.
- The order in which sound travels: round window, stapes, malleus, incus, tympanic membrane, endolymph, perilymph.
- How does sound dissipate? Via the perilymph, via the air, etc.
- How to differentiate between a low-pitched male voice and a high pitched female voice? By different processing areas in the brain, by frequency, by intensity, by amplitude.
- Visible range of light? 400-700 nm.
- Shorter than 400 nm? Ultraviolet.
- Which cranial nerves have nothing to do with the eye? Nerve I.
- What is the visual acuity of somebody that can count fingers from 6 meters away? 6/60, 6/100, 6/30.
- How can the finger discriminate between two points better than the neck? Narrow receptive field, larger area of the brain representing the finger.
- Synapse between second and third order neurons occurs in?
- Sympathetic response: dilator muscle contracts.
- What happens after long periods of being in the dark? Rhodopsin degrades less.
- What structure controls how much light enters the eye? Pupil, iris, ciliary muscle.
- Far vision: Cone.
- Touch receptor uses: mechanically gated channel.
- Third order soma is found in thalamus.
- Fast pain, neothalamic something.
- Sympathetic: dilator muscle contracts.
- Horse hair on arm activates what receptor using what pathway.
- Finger in warm water: lateral spinothalamic tract.
- Synapse of 1,2 order neurons: cornu post.
- Mechanical gated channels for: touch.
- What is the purpose of Rinne Test?
- What is the purpose of Schwabach Test?
- What is the purpose of Weber Test?
- What is the content of endolymph? High potassium, almost no sodium.
- What is the function of hairy cells corti organ? Transform sound waves to nerve impulses.
- Ion which causes depolarization in the ear? Potassium.
- The distance that is used to measure a person's vision? 6 meters.
- A patient is a patient myopia, where will the light converge in the eyes? Before the retina.
- The spherical concave lens is used for patients with what? Myopia.
- What lens do patients suffering from presbyopia use? Bifocals/complex.
- Name of the waves with a length of less than 400 nm? Ultraviolet.
- Vision near and far will be bad, an abnormality of the refraction. Presbyopia.
- What is the minimum angle formed? 1 minute.
- Nucleus in charge of the pupillary reflex? Edinger-Westphal.
- What is the power of the lens in children?
- What is the power of the lens of adults?
- Most common receptors in our body?
- Right hand's fingertips dipped in warm water. Five minutes later, the left hand's fingertips are also dipped into the warm water and feel a different sensation, why? Adaption.
- What causes our bodies to become more adaptive to a stimulus?
- What is an example of proprioception receptors?
- If we put our hands in cold water that is 2 degrees celsius, then the hand will feel? Pain.
- What is a phasic receptor and examples? Pacinian and Meissner.
- How do you compare the sensation of touch in the area of skin with and without hair?
- Impulse delivered by DCML path?
- Impulse delivered by ALS pathways?
- What is the function of nucleus in DCML and ALS tracts?
