Final Review Part 2

Front 1

compare and contrast lens and cornea:

Back 1

lens can be shaped, cornea is static...both allow light in...both are transparent...not vascular.Lens focuses, cornea Protects

Front 2

function of ciliary muscles

Back 2

pupil diameter and hold and alter shape of lens

Front 3

describe the retina:

Back 3

photoreceptor, bipolar and ganglion (inside to outside)....ganglion layer is surface of retina ****the ganglion consists of unipolar neuron forms optic nerve, T or F ..... answer is FALSE**** function of bipolar layer ****consists of bipolar neurons performs unknown function in mammals, T or F.,.answer is TRUE*****

Front 4

list the major landmarks of the spinal cord

Back 4

cervical enlargement, lumbar enlargement, conus medullaris, filum terminale and cauda equine. Where does conus medullaris end? between L1 and L2.

Front 5

contralateral

Back 5

opposite side

Front 6

ipsilateral

Back 6

same side

Front 7

explain CSF

Back 7

made by coroid plexus in lateral ventricles, runs from brain thru spinal cord, no red blood cells, blood brain barrier(tight junctions around brain capillaries forms the blood barrier, the barrier is selective in what can cross)....has no immune response, so we have no defense in the spinal cord or brain (meningitis)

Front 8

corpus collosom

Back 8

acts as gateway between the two hemispheres of brain

Front 9

what is function of fovea centralis

Back 9

highest concentration of photo receptors’, sharpest image put image there

- optic nerve is conduit out of eye for nerve impulses generated there ....
• -optic disc is the blind spot

Front 10

eye movement:

Back 10

muscles 4 rectus, 2 obliques

Front 11

compare and contrast lens and cornea:

Back 11

lens can be shaped, cornea is static...both allow light in...both are transparent...not vascular.Lens focuses, cornea Protects

Front 12

Front 13

Front 20

eye movement:

Back 20

muscles 4 rectus, 2 obliques

Front 21

decussation

Back 21

contralateralization are the same....cross over.

Front 22

amygdala

Back 22

place for emotional memory normal shapes

Front 23

meningitis

Back 23

inflammation of dura, arachnoid and pia maters

Front 24

spinal cord end at

Back 24

L1

Front 25

encephalitis

Back 25

inflammation of brain and neurons is TRUE
