Study Notes
SEXUAL RESPONSE CYCLE
- Sexual response cycle characterized by increased heart rate, muscle tension, and vasocongestion leading to heightened sensitivity and excitement. This is the excitement phase.
- Positive psychological states enhance sexual pleasure, while stress or anxiety diminish arousal during the plateau phase.
- Males typically experience more intense, shorter orgasms, while females can have multiple orgasms with varying intensity.
- Hormones like oxytocin and prolactin promote relaxation and bonding, helping the body return to a baseline state during the resolution phase.
- External factors like relationship dynamics and stress can negatively affect arousal and enjoyment in any phase of the cycle.
FERTILIZATION
- Sperm preventing polyspermy is primarily done via the cortical reaction.
- Fertilization enhances genetic diversity through random allele combination from two parents.
- The zona pellucida acts as a barrier for sperm penetration during fertilization.
IMPLANTATION
- The endometrium thickens and secretes nutrients and signaling molecules to prepare for implantation.
- Inadequate progesterone may lead to embryo expulsion.
- Presence of uterine abnormalities can negatively influence implantation.
- Cytokines and growth factors promote communication between the growing embryo and endometrium, facilitating attachment and implantation.
- The blastocyst stage allows embryo implantation into the uterine wall.
- Invasion and remodeling of maternal tissue by the trophoblast occurs.
- Maternal immune system response supports embryo implantation by suppressing activity to tolerate it.
- Human Chorionic Gonadotropin (hCG) helps maintain progesterone production in early pregnancy and is an indicator of potential pregnancy.
- A failed implantation can result in a chemical pregnancy.
- Ectopic pregnancy can result from abnormal fallopian tubes.
- Endometrial receptivity timing and success of embryo attachment are important factors in successful implantation.
- Implantation is crucial for embryonic development because of the transfer of nutrients.
- A proper maternal diet during implantation can enhance endometrial receptivity.
ESTIMATED DATE OF CONFINEMENT (EDC)
- Naegele's rule is useful for calculating an estimated date of confinement using a woman's last menstrual period (LMP).
FUNDAL HEIGHT
- A measurement of the size of the uterus at different stages of pregnancy can help doctors assess fetal growth.
- Fundal height measurements in centimeters should accurately reflect fetal development during pregnancy.
- McDonalds rule and Bartholomews rule are useful ways to understand normal fetal growth.
LABOR
- Maternal anxiety and stress can affect labor progression.
- Obesity during pregnancy increases the risk of complications during labor.
- Staying mobile and changing positions during labor can improve progression.
- Risk of post-term complications increase as pregnancy lengthens beyond 41 weeks.
- Supportive partners can impact successful coping mechanisms and emotional support.
- Braxton Hicks contractions are intermittent, irregular uterine contractions and are not true markers of labor.
- Regular, consistent contractions are associated with the start of active labor.
