Uterine contraction. Uterine contractions are muscle contractions of the uterine smooth muscle that can occur at various intensities in both the non-pregnant and pregnant uterine state. The non-pregnant uterus undergoes small, spontaneous contractions in addition to stronger, coordinated contractions during the menstrual cycle and orgasm.
The key is to differentiate Braxton Hicks contractions from true labor contractions (see Table 1 above). Most commonly, Braxton Hicks contractions are weak and feel like mild cramping that occurs in a localized area in the front abdomen at an infrequent and irregular rhythm (usually every 10-20 minutes), with each contraction lasting up to 2 ...
Uterine Tachysystole is a condition of excessively frequent uterine contractions during pregnancy. [1] It is most often seen in induced or augmented labor, though it can also occur during spontaneous labor, [2] and this may result in fetal hypoxia and acidosis. This may have serious effects on both the mother and the fetus including ...
A vaginal delivery is the birth of offspring in mammals ( babies in humans) through the vagina (also called the "birth canal"). [1] It is the most common method of childbirth worldwide. [2] It is considered the preferred method of delivery, as it is correlated with lower morbidity and mortality than caesarean sections (C-sections), [3] though ...
Anatomical terminology. [ edit on Wikidata] The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes [1]) but also of supporting stromal and vascular tissue. [2] Its main function is to induce uterine contractions .
Pain management during childbirth is the partial treatment and a way of reducing any pain that a woman may experience during labor and delivery. The amount of pain a woman feels during labor depends partly on the size and position of her baby, the size of her pelvis, her emotions, the strength of the contractions, and her outlook. [1]
Cardiotocography ( CTG) is a technique used to monitor the fetal heartbeat and uterine contractions during pregnancy and labour. The machine used to perform the monitoring is called a cardiotocograph . Fetal heart sounds were described as early as 350 years ago and approximately 200 years ago mechanical stethoscopes, such as the Pinard horn ...
Fergusson reflex. The Fergusson reflex (also called the fetal ejection reflex) is the neuroendocrine reflex comprising the self-sustaining cycle of uterine contractions initiated by pressure at the cervix, more precisely, the internal end of cervix, or vaginal walls. It is an example of positive feedback in biology.
