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.
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
An antagonist muscle reverses the action of a prime mover. When the prime mover contracts to produce a movement, the antagonist muscle relaxes to allow that movement to occur in the opposite direction. This coordination between prime movers and antagonists is essential for controlled and coordinated movement.
brachialis
The muscle that is primarily responsible for bringing about a particular movement is called the prime mover or agonist muscle. It is the main muscle that contracts to create the desired movement at a joint. Antagonist muscles work in opposition to the prime mover to control the movement and prevent injury.
The prime mover in ankle dorsiflexion is the tibialis anterior muscle, which is located at the front of the shin. This muscle contracts to pull the foot upward, allowing for dorsiflexion of the ankle joint.
The diaphragm is the prime mover of inspiration, as it contracts and flattens during inhalation, creating a vacuum in the chest cavity that allows air to be drawn into the lungs.
Diaphragm
Antagonist: Controls movement, opposite of prime mover Prime Mover: Main muscle that is directly responsible for movement Synergist: Aids in movement of muscle
Prime mover is the bicep and the antagonist is the tricep.
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
antagonist
The Gastrocnemius (calf muscle) is the primary mover. The Synergist (or assistor) muscle is the Soleus.
An antagonist muscle reverses the action of a prime mover. When the prime mover contracts to produce a movement, the antagonist muscle relaxes to allow that movement to occur in the opposite direction. This coordination between prime movers and antagonists is essential for controlled and coordinated movement.
The fixator of a muscle stabilizes the muscle at the point of origin.
