Answer:
The correct option is : a. The phrenic nerve from the cervical plexus
Explanation:
The diaphragm is a thin skeletal muscle which separates the thoracic cavity and the abdominal cavity.
The phrenic nerve is a nerve present in the thoracic region, that passes down between the heart and the lung and reaches the diaphragm.
The phrenic nerve innervates the diaphragm from the C3–C5 of cervical plexus.
The available options are:
a) Push-up plus off a wall → shoulder IR/ER → seated DB press
b) Shoulder IR/ER → push-up plus → seated DB press
c) Shoulder IR/ER → seated DB press → push-up plus
d) High-rep bench press → shoulder IR/ER → abdominal crunch
Answer:
A. Push-up plus off a wall -> shoulder IR/ER -> seated DB press
Explanation:
A push-up plus off a wall is an example of a closed chain exercise as the arm is fixated to a stationary surface.
It also make your shoulder blades to move freely, making serratus anterior stronger, a vital muscle that keeps scapula stable and helps it rotate upward. This in turn reduces shoulder impingement when push-ups plus off a wall is done.
Shoulder IR/ER also helps to correct the imbalance in the rotator muscles of the shoulder.
Also, seated DB press strengthens all muscles of the shoulder in a functional way.
