Reproduction – parturition, neonatal physiology, lactation
Parturition – control • Parturition requires myometrial contractions and cervical softening. • The myometrium is a functional syncytium (coupled by gap junctions) so contractions are coordinated. Contractions occur because action potentials cause Ca influx; oestrogen-primed myometrium shows pacemaker potentials, which initiate APs if they are large enough. Prostaglandins liberate Ca from intrac...
