CSF Pathway
|
CSF is secreted by choroid plexus in each lateral ventricle
> CSF flows through interventricular foramina into third ventricle > Choroid plexus in 3rd ventricle adds more CSF > CSF flows down cerebral aqueduct to 4th ventricle > Choroid plexus in 4th ventricle adds more CSF; fluid also can continue down the central canal of the spinal cord from the 4th ventricle > CSF flows out two lateral apertures and one median aperture > CSF fills subarachnoid spaces and bathes external surface of brain and spinal cord > At arachnoid granulations CSF is reabsorbed into venous blood of dural venous sinuses |
|
|
vertebral canal penetration from outer to inner
|
epidural space > dura mater > arachnoid > subarachnoid space > pia mater
|
|
|

what tissue is dura mater
|
dense irregular ct
|
|
|
what is arachnoid
|
avascular, modified loose ct w/ weblike extensions of collagen and elastic fibers
|
|
|

|
csf made by ependymal cells
|
|
|
what is lumbar cistern
|
a sub arachnoid space inferior to medullary cone
|
|
|
tissue of pia mater
|
collagen and a few elastic fibers
|
|
|
pathway of sound
|
pinna > auditory canal > tympanic membrane > ossicles: malleous > incus > stapes > oval window > perilymph in cochlea > endolymph in cochlear duct > hair cells in spiral organ of corti
|
|
|
path of light to central fovea
|
cornea > anterior chamber filled with aqueous fluid > pupil > posterior chamber filled with aqueous fluid > lense > posterior cavity filled with vitreous humor > central fovea
|
|
|
layers of retina light passes
|
nerve fiber > ganglion cells > photo receptors > pigment epithelium > choroid
|
|
|
visual information pathway
|
reception of photon by photoreceptor cell > ganglion cells > nerve fibers > optic nerve (ganglion cell axons) > optic chiasm (1/2 cross to other side) > optic tracts > thalamus > cerebrum
|
