Just question 16
Just question 16
Muscle is a delicate tissue found in many creatures. Muscle cells consist of protein fibers of actin and myosin that slide past each other, delivering a constriction that changes both the length and the state of the cell. Muscles work to deliver strength, stability and movement.
The levator ani emerges, in front, from the back surface of the superior pubic ramus lateral than the symphysis; behind, from the inward surface of the spine of the ischium; and between these two focuses, from the obturator sash. The filaments pass descending and in reverse to the centerline of the floor of the pelvis. The most posterior are embedded into the side of the last two portions of the coccyx. Hence the first option is incorrect as the origin (A) is right but the insertion (B) is incorrect. Levator ani is only inserted into coccyx and not sacrum.

The filaments pass descending and in reverse to the centerline of the floor of the pelvis. The most posterior are embedded into the side of the last two portions of the coccyx. Hence the third option is incorrect as the origin (A) is incorrect though the insertion (B) is correct.
