Diaphragm is the the prime mover for the inhalation. It is a dome shaped partition between the thorax and the abdomen. It gets some what flat as it contracts. The volume of the thorax increases. There by the air is pulled in the thorax.
While there are a lot of muscles involved, the most important muscle of respiration is the diaphragm.
it is the diaphragm
a prime mover is the main muscle that causes movement. In the case of the hip flexion, the prime mover would be the rectus femoris or the ilopsoas

Antagonist: A muscle that opposes a prime mover

The Diaphragm.
A prime mover is the muscle that has the most influence in one direction on the joint it acts on. For example the prime mover in extension of the forearm is the triceps.
An agonist (prime mover)
Prime mover in medical terms means the muscle that is mainly responsible for a given motion.
a prime mover is the main muscle that causes movement. In the case of the hip flexion, the prime mover would be the rectus femoris or the ilopsoas
Quadricepts
antagonist
The Gastrocnemius (calf muscle) is the primary mover. The Synergist (or assistor) muscle is the Soleus.
Prime mover is the bicep and the antagonist is the tricep.
The fixator of a muscle stabilizes the muscle at the point of origin.
