Hello toothfairy,

Thank you for your reply.Where did you get the answer #2 from? Which resource? I was looking everywhere and was hard to find. #1, still looking, and no luck yet. Here you go some others:

1- Optic nerve fibers from the nasal half of the retina cross the midline and enter the optic tract of the opposite side by way of the
a. optic chiasma
b. lateral geniculate body
c. bipolar cells of the retina
d. brachium of the superior colliculus
e. geniculocalcarine tract (optic radiations)

2-Sensation from the left face and teeth are interpreted in which of the following lobes
a. left frontal
b. right frontal
c.left parietal
d. right parietal
e. right temporal.

These ones i'm not sure about the answers:

3-In a histologic section through the spiphyseal plate of the femur of an 18 years old male, which of the following is the zone in which cartilage lacunae appear swollen and the condrocytes are large? 1 proliferation creo que esta es la respuesta , but not sure.
2. bone deposition
3. reserve cartilage
4. cartilage calcification
5 hypertrophy and maduration.

4- Inability to move the diafragm is consistent with a total section of the espinal cord at wich of the following spinal levels?
a. C2 maybe this.
b. C6
c. C7
d. C8
e. T2

i hope this diagram helps!!!!!

 

[faddawe]

i can guarantee the no.2 ,i had atlas infront of me and i checked it because the ant scalene is belonging to the neck muscles and it is wraped in the prevertebral fascia
but please can you tell me does these questions come in the exam

 

[faddawe]

hope this helps..

diaphram inner. is by phrenic and phrenic is from c3,c4,c5 so the cut should be in c2 to stop the phrenic nerve which is the answer

diaphram inner. is by phrenic and phrenic is from c3,c4,c5 so the cut should be in c2 to stop the phrenic nerve which is the answer for question no.4

for question no.2 i think it will be the left parietal because cranial neres o ot decssate
if you have any other opinion let me know
