Answer: Subarachnoid
Explanation:
The space in the meninges below the arachnoid membrane and above the pia mater contains the cerebrospinal fluid. Cerebrospinal fluid is produced by choriod plexus( a cluster of capillaries) from the blood. Blood vessels traveling within the subarachnoid space deliver oxygen and nutrients to the spinal cord.
Some unicellular organisms are similar to animals because they have the ability to move.
Third option
Assessing flexibility, strength and movement patterns is therefore always a good idea.
1) Lying Pelvic Tilt
2) Standing Pelvic Tilt (SPT)
3) Learn and Ingrain the Hip Hinge Pattern
4) Strengthen the Posterior Pelvic Tilt Movement Pattern/Muscles that Produce Posterior Pelvic Tilt
5) Incorporate squats, deadlifts, presses, and other compound lifts with good technique
