When pressure is exerted on the vestibular bulbs (3) and the crus of clitoris (4), e.g. by the thrusting of the penis or the reflex- ive contractions of the muscles that surround these structures, blood is forced into the clitoral body and the clitoral glans via the pars intermedia. The increase in pressure leads to a lowering of the sensory receptor ac- tivation threshold and a consequent activation of the numerous senso- ry nerve endings (genital corpuscles and corpuscles of Pacini) dedicated to generating sexual excitation, which ul- timately leads to orgasm.

    Color Code Important Female Perineum Doctors Notes Notes/Extra explanation Please view our Editing File before studying this lecture to check for any changes. Objectives At the end of the lecture, the student should be able to describe the: ✓ Boundaries of the perineum. ✓ Division of perineum into two triangles. ✓ Boundaries & Contents of anal & urogenital triangles. ✓ Lower part of Anal canal. ✓ Boundaries & contents of Ischiorectal fossa. ✓ Innervation, Blood supply and lymphatic drainage of perineum. Lecture Outline ‰ Introduction: • The trunk is divided into 4 main cavities: thoracic, abdominal, pelvic, and perineal. (see image 1) • The pelvis has an inlet and an outlet. (see image 2) The lowest part of the pelvic outlet is the perineum. • The perineum is separated from the pelvic cavity superiorly by the pelvic floor. • The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus muscle, and associated connective tissue. (see image 3) We will talk about them more in the next lecture. Image (1) Image (2) Image (3) Note: this image is seen from ABOVE Perineum (In this lecture the boundaries and relations are important) o Perineum is the region of the body below the pelvic diaphragm (The outlet of the pelvis) o It is a diamond shaped area between the thighs. Boundaries: (these are the external or surface boundaries) Anteriorly Laterally Posteriorly Medial surfaces of Intergluteal folds Mons pubis the thighs or cleft Contents: 1.

    I ANATOMY PELVIC FLOOR & COLORECTAL OVERVIEW Definition of pelvic floor From genitalia to organs, superior endopelvic supportive tissues 3 layers of muscle, different muscles within each layer Intervening layers of fascia surrounding each muscle Fascial thickening = ligaments Endopelvic connective tissue surrounding all viscera Functions of pelvic floor Support of the organs Sphincteric of the outlets (urethra, vagina, rectum) and openings (meatus, introitus, anus) Sexual – providing tone for the vaginal and rectal canals Stabilization “Sump Pump” Lymphatic Terminology Confusing as to what specific anatomical reference Different disciplines emphasize different structures Changing – pubococcygeus is now the pubovesical Mobility versus stability concept Organs and outlets need to expand and be mobile Too much mobility is prolapse or incontinence Too much fixation/stability is painful The concept of organ mobility and stability is key to understanding dysfunctions of the pelvic floor. The organs are sacs that are meant to move, expand and empty. This is true for the bladder, uterus, vagina, rectum and colon. Should they not be able to expand fully because of fibrotic attachments, endometrial adhesions, tissue changes or scarring from surgery, the patient may present with symptoms of pressure, pain, constipation, urinary frequency, dyspareunia, urethral syndrome, to name but a few. Should the organs not be stabilized in their proper positions because of weakened or torn muscles and ligaments, problems such as prolapse, perineal pressure,

  • The Female Reproductive System
    The Female Reproductive System Anatomy of the Female Reproductive System The human female reproductive system contains two main parts: the uterus and the ovaries, which produce a woman’s egg cells. LEARNING OBJECTIVES Outline the anatomy of the female reproductive system from external to internal KEY TAKEAWAYS Key Points An female’s internal reproductive organs are the vagina, uterus, fallopian tubes, cervix, and ovary. External structures include the mons pubis, pudendal cleft, labia majora and minora, vulva, Bartholin’s gland, and the clitoris. The female reproductive system contains two main parts: the uterus, which hosts the developing fetus, produces vaginal and uterine secretions, and passes the anatomically male sperm through to the fallopian tubes; and the ovaries, which produce the anatomically female egg cells. Key Terms ovary: A female reproductive organ, often paired, that produces ova and in mammals secretes the hormones estrogen and progesterone. oviduct: A duct through which an ovum passes from an ovary to the uterus or to the exterior (called fallopian tubes in humans). vulva: The consists of the female external genital organs. oogenesis: The formation and development of an ovum. The human female reproductive system (or female genital system) contains two main parts: 1. Uterus o Hosts the developing fetus o Produces vaginal and uterine secretions o Passes the anatomically male sperm through to the fallopian tubes 2. Ovaries o Produce the anatomically female egg cells. o Produce and secrete estrogen and progesterone These parts are internal; the vagina meets the external organs at the vulva, which includes the labia, clitoris, and urethra. The vagina is attached to the uterus through the cervix, while the uterus is attached to the ovaries via the fallopian tubes.
