following ways?
a. Between the tendons of the extensor digitorum longus and fibularis (peroneus)
tertius muscles
b. Between the tendons of the extensor hallucis and extensor digitorum muscles
c. Between the tendons of the tibialis anterior and extensor hallucis longus
muscles
d. Immediately anterior to the lateral malleolus
e. Immediately posterior to the medial malleolus
494.Why is the sacral hiatus notused as an access point for spinal taps?
a. Because it is covered by a thick anterior sacrococcygeal ligament
b. Because CSF only flows down as inferiorly as S2, and thus is too cranial to be
reached

increasing the chances of unintentional contamination
d. Because the filum terminale would likely be damaged
e. Because the caudal posterior sacral foramina would be easier points of access
to CSF
