Your baby's sex is set at conception. At around 7 weeks, your baby's internal sex organs – such as ovaries and testes – begin to form in the abdomen. Male and female sex organs and genitalia look the same at this stage because they're derived from the same structures. At around 9 weeks, boys and girls begin to develop differently. In girls, a tiny bud emerges between the tissue of the legs. This bud will become the clitoris. The membrane that forms a groove below the bud separates to become the labia minora and the vaginal opening. By 22 weeks, the ovaries are completely formed and move from the abdomen to the pelvis. They already contain a lifetime supply of 6 million eggs. In boys, the bud develops into the penis and starts to elongate at around 12 weeks. The outer membrane grows into the scrotal sac that will later house the testicles. By 22 weeks, the testes have formed in the abdomen. They already contain immature sperm. Soon they'll begin their descent to the scrotum, but it's a long journey. They'll reach their destination late in pregnancy, or for some boys, after birth. If you're eager to find out whether you're having a girl or a boy, you'll have to wait until you're at least 17 weeks pregnant. That's when the genitals have developed enough to be seen on an ultrasound.

Loyola Breast Examination part 2 Medical breast examination of a female from Loyola University,Chicago

Fertilization of the egg with sperm generally occurs during the two weeks following the first day of your last menstrual period.1 The week of pregnancy that you are entering is dated from the first day of your last period. This means that in the first two weeks or so, you are not actually pregnant - your body will be preparing for ovulation as normal.

This short clinical-skills video demonstrates an intramuscular injection being given to a female patient. Intramuscular injections deliver medication deep into the muscle tissue, and correct site selection and technique are essential parts of everyday nursing and clinical practice.

The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus, and associated connective tissue which span the area underneath the pelvis. The pelvic diaphragm is a muscular partition formed by the levatores ani and coccygei, with which may be included the parietal pelvic fascia on their upper and lower aspects. The pelvic floor separates the pelvic cavity above from the perineal region (including perineum) below.

The right and left levator ani lie almost horizontally in the floor of the pelvis, separated by a narrow gap that transmits the urethra, vagina, and anal canal. The levator ani is usually considered in three parts: pubococcygeus, puborectalis, and iliococcygeus. The pubococcygeus, the main part of the levator, runs backward from the body of the pubis toward the coccyx and may be damaged during parturition. Some fibers are inserted into the prostate, urethra, and vagina. The right and left puborectalis unite behind the anorectal junction to form a muscular sling . Some regard them as a part of the sphincter ani externus. The iliococcygeus, the most posterior part of the levator ani, is often poorly developed.

The coccygeus, situated behind the levator ani and frequently tendinous as much as muscular, extends from the ischial spine to the lateral margin of the sacrum and coccyx.

The pelvic cavity of the true pelvis has the pelvic floor as its inferior border (and the pelvic brim as its superior border.) The perineum has the pelvic floor as its superior border.

Some sources do not consider “pelvic floor” and “pelvic diaphragm” to be identical, with the “diaphragm” consisting of only the levator ani and coccygeus, while the “floor” also includes the perineal membrane and deep perineal pouch. However, other sources include the fascia as part of the diaphragm. In practice, the two terms are often used interchangeably.

Inferiorly, the pelvic floor extends into the anal triangle.

This ophthalmology video documents the drainage of a large cyst affecting a young patient's eye. The recording shows the procedure in a clinical setting, where the cyst is opened and its contents are cleared to relieve the swelling around the eye. The procedure is a common minor operation in eye care.

This dermatology video shows the removal of a large blackhead that has been present on the skin for many years. The recording follows the extraction in a clinical setting, showing how the clogged pore is opened and cleared. Blackheads form when a pore becomes blocked with oil and dead skin cells.

This pediatrics video demonstrates the abdominal examination in a child, using the standard sequence taught at the bedside. The assessment includes inspection, palpation, percussion, and auscultation, adapted for the examination of younger patients. Abdominal examination is a core part of the pediatric physical assessment.

This video shows the removal of an unusually long ingrown hair from the skin. An ingrown hair develops when a hair curls back and grows into the skin instead of outward, and the recording documents the extraction step by step. Ingrown hairs are a common minor skin complaint and can cause local irritation or inflammation.

This pediatrics video demonstrates the examination of the lungs and respiration in newborns and children. The assessment covers the breathing pattern, chest movement, and lung sounds, which are central elements of the respiratory examination in young patients. Respiratory assessment is one of the most frequently performed checks in child health.

This gynecology video demonstrates the rectovaginal examination, a clinical assessment used to evaluate the pelvic structures. The recording shows how the examination is performed as part of a complete pelvic assessment in a medical setting. It is a standard component of specialist gynecological assessment.

This urology video demonstrates Foley catheter insertion in both male and female patients. The recording shows the sterile technique used to place an indwelling urinary catheter, a routine procedure in hospital, surgical, and nursing care. Urinary catheters drain the bladder when a patient cannot pass urine normally.

This video demonstrates the testicular self-examination, a simple check used to detect lumps or changes in the testicles. Regular self-examination supports early detection of testicular cancer, and the recording shows how the check is performed step by step. Testicular cancer mainly affects younger and middle-aged men, which makes regular self-checks worthwhile.

This clinical-skills video demonstrates a range of suturing techniques used to close wounds and surgical incisions. The recording shows several stitch patterns and how each one is placed, making it a practical reference for students learning wound closure. Suturing is one of the fundamental practical skills in medicine and surgery.

This surgical video shows an open appendectomy, the operation to remove the appendix through an abdominal incision. The recording follows the procedure in the operating room, showing the main steps of one of the most common emergency operations. Appendectomy is the standard treatment for appendicitis.

This animation demonstrates endotracheal intubation, the procedure in which a breathing tube is passed into the trachea to secure a patient's airway. Animated demonstrations of this kind are used to teach the sequence of steps before hands-on clinical practice. Airway management is a core skill in anaesthesia and emergency medicine.

This surgical video shows the removal of a hematoma, a localized collection of blood that forms outside the blood vessels. The recording documents the procedure in the operating room, where the collection is opened, cleared, and the area is cleaned. Hematomas can develop after injury, surgery, or bleeding disorders.

Normal Heart Sounds With the aid of a stethoscope you can hear the characteristic sounds of the normal heartbeat, typically described as a "lub-dub." These sounds are produced by the closure of the heart valves. The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall. This "dub" sound is typically heard as a sharp snap because the semilunar valves tend to close much more rapidly than the AV valves. Because diastole occupies more time than systole, a brief pause occurs after the second heart sound when the heart is beating at a normal rate. Therefore, the pattern that one hears is one of: "lub-dub" pause, "lub-dub" pause, and so on. Sometimes, especially in young normal individuals, a third heart sound can be heard. This sound is produced by the very rapid influx of blood into the partially filled ventricle. It is typically very faint and as such difficult to hear.
