ayy just took notes on this last night!
Thyroglobulin is synthesized in a follicle cell and is then transported into the follicle lumen. Iodide is actively transported into the follicle cell and then diffuses into the lumen, where it is oxidized into iodine. One iodine atom is joined with the tyrosine molecules within the thyroglobulin to make monoiodotyrosine (MIT), and two iodine atoms are joined with the tyrosine to make diiodotyrosine (DIT). Two DIT molecules are then joined to make T4, or one MIT and one DIT molecule are joined to form T3. T3 and T4, still attached to thyroglobulin, are then endocytosed into the follicle cell, where they are separated from thyroglobulin by lysosomes. T3 and T4 then diffuse into the bloodstream.

1. Name the six types of generalized seizures and their corresponding signs and symptoms.
2. What is status epilepticus?
Answer
1a. "Grand Mal"/Tonic-clonic seizures: loss of consciousness, muscles suddenly tense and tighten, hard to breathe, rapid muscle contractions/spasms/jerks 2a. "Petit Mal"/Absence seizures: stare with no movement, return to alertness within 20 seconds, confuse with daydreaming, may blink/chew/hand gestures, impairment of consciousness 3a. Myoclonic seizures: increase in muscle tone, sporadic jerking movements, shock-like, brief 4a. Clonic seizures: repetitive, jerking movements, rapidly alternating contractions 5a. Tonic seizures: muscle stiffness/tense, muscle tone enhanced, falls down if standing, may turn blue/stop breathing 6a. Atonic seizures: muscles go limp/sudden loss of tone, slump or crumple to ground, drop attacks/seizures, may get injured upon falling b. Status epilepticus is an epileptic seizure > 5 minutes or more than one seizure in 5 minutes with impairment of consciousness throughout. Commonly a serious medical condition. Does anyone know in which of the above 6 consciousness is lost? Is it only in 1a and 1b?

Yeeup that's correct; your turn!
bhavjain,
I believe that consciousness is usually lost in all 6 generalized seizures.

bhavjain,

mangothecat,
Sources? I've looked and every source seems to agree that consciousness is lost in grand mal and petit mal, but they disagree on the other 4. According to the Epilepsy Foundation, for instance, consciousness is "usually preserved" in a tonic seizure. http://www.epilepsy.com/learn/types-seizures/tonic-seizures
Is a virus, bacterium, or fungi responsible for conjunctivitis? Which specific virus, bacterium, or fungi is by far the most common cause?

answer
Conjunctivitis can be caused by all three, though fungal infections are rare. The most common cause of conjunctivitis is the adenovirus (I think :? )
bhavjain,
Here's where I got that info from: http://www.merckmanuals.com/professional/neurologic-disorders/seizure-disorders/seizure-disorders. Looks like medical professionals disagree on many things lol

mangothecat,
Even that site says that consciousness is usually not lost in tonic and myoclonic seizures...?

bhavjain,
ehehehehehe sorry :oops: yeah it says that consciousness is usually not lost in myoclonic seizures. However it said that most tonic seizures occur during sleep, so they aren't conscious to begin with. (Did I skip over anything saying that consciousness is not lost in tonic seizures occuring when one is awake? ahhh sorry) http://www.hopkinsmedicine.org/neurology_neurosurgery/centers_clinics/epilepsy/seizures/types/tonic-and-clonic-seizures.html also states that consciousness is lost in tonic seizures.
1. How would damage to the optic chiasma affect one's field of vision?
2. How would damage to the right optic tract affect one's field of vision?
3. ________ sparing is a vision field phenomenon that may occur after a posterior cerebral artery stroke.

Thanks. I agree, consciousness is only preserved in myoclonic.
Answer
1. Damage to the optic chiasma would lead to bitemporal hemianopsia; the outer half of both left and right eyes loses vision. 2. Damage to the right optic tract would lead to left homonymous hemianopsia; the left half of both left an right eyes loses vision. 3. Macular sparing is a vision field phenomenon that may occur after a posterior cerebral artery stroke.
