Explanation / Answer
1.Spinous process is the elongated process present in the posterior aspect of vertebra. Various segments of vertebra contains spinous process of characteristic shape however all of them are common is their direction i.e. they are posteriorly directed.
When vertebral column is flexing or extending spinous process moves in superior or inferior plane
In spinal flexion, spinous process moves in superior direction
In spinal extension spinous process moves in inferior direction
Q2. ASIS is anterior superior iliac spine
PSIS is posterior superior iliac spine
ASIS and PSIS moves on hip flexion or extension
Hip flexion/extension is achieved via thigh movement
During hip flexion thigh is moved forward, and during hip extension hip moves backward
Q3.when femur is adducted
The long axis of femur moves in there fore greater troachenter which is on the upper portion of femur moves outward
There is external rotation of greater trochanter
