kicking a football is accomplished by knee:
pronation.
adduction.
extension.
flexion.
question 20
1 pts
which muscle group extends the vertebral column and also flexes the back laterally and rotates it a little?
errector spinae
levator ani
rectus abdominis
serratus anterior

Explanation:

For Question 19, kicking a football involves straightening the knee joint, which is knee - extension. Pronation is related to forearm or foot movements, adduction is moving a body part towards the mid - line, and flexion is bending the joint.
For Question 20, the erector spinae muscles are responsible for extending the vertebral column, laterally flexing the back, and some rotation. The levator ani is involved in pelvic floor support, the rectus abdominis flexes the trunk, and the serratus anterior is involved in scapular movement.

Answer:

Question 19: C. extension
Question 20: A. erector spinae
