Indicate all communicating regions and primary landmarks along the path and BE SPECIFIC naming the relevant structures. ewilliamshatala2 https://padlet.com/ewilliamshatala2/qtv2ahfzydgko588/wish/1743130002 ANSWER:
Abdominal aorta (bifurcates @ L4/L5) / common iliac artery (bifurcates @ SI joint) / external iliac artery (deep to inguinal ligament) / femoral artery (through triangle in the femoral sheath, adductor canal, then thru the adductor hiatus) / popliteal artery (popliteal fossa, thru tendinous arch of soleus) / posterior tibial artery (posterior deep compartment of the leg) / anterior tibial (thru proximal aperature of interosseous membrane, between Tib anterior and EDL, deep retinacula, superior and inferior) / dorsalis pedis]]> 2021-09-15 15:20:03 UTC https://padlet.com/ewilliamshatala2/qtv2ahfzydgko588/wish/1743130002 Multiple Choice #3 ewilliamshatala2 https://padlet.com/ewilliamshatala2/qtv2ahfzydgko588/wish/2712973291 The following statement(s) is/are true regarding the walking gait:
