1
Q
patellar reflex
A
stimulus: overstretching of quadricep
response: contraction of quadricep
significance: lack of reflex may indicate damage to lumbar region (L2-L4)
- monosynaptic reflex: no neurons involved
2
Q
achilles reflex
A
stimulus: overstretching of the muscle
response: contraction of the muscle
significance: lack of reflex may indicate damage from L5-S1
3
Q

A
choroid plexus -> lateral ventricle -> interventricular foramen -> third ventricle -> cerebral aqueduct -> fourth ventricle -> apertures -> subarachnoid space -> arachnoid villi -> dural sinuses -> venous system
