powers
Last reviewed 05/2021
There are primary and secondary powers:
- the primary power is the process of uterine contraction, relaxation and retraction
- the secondary powers are the voluntary contraction of the muscles of the diaphragm and abdominal wall
There are several disorders of uterine action:
- hypotonic contraction
- hypertonic contraction
- constriction ring formation
Voluntary contractions are disrupted by exhaustion, dehydration, and emotional distress.
