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.

Lab #23 Anal Triangle
THE BONY PELVIS AND ANAL TRIANGLE (Grant's Dissector [16th Ed.] pp. 141-145) TODAY’S GOALS: 1. Identify relevant bony features/landmarks on skeletal materials or pelvic models. 2. Identify the sacrotuberous and sacrospinous ligaments. 3. Describe the organization and divisions of the perineum into two triangles: anal triangle and urogenital triangle 4. Dissect the ischiorectal (ischioanal) fossa and define its boundaries. 5. Identify the inferior rectal nerve and artery, the pudendal (Alcock’s) canal and the external anal sphincter. DISSECTION NOTES: The perineum is the diamond-shaped area between the upper thighs and below the inferior pelvic aperture and pelvic diaphragm. It is divided anatomically into 2 triangles: the anal triangle and the urogenital (UG) triangle (Dissector p. 142, Fig. 5.2). The anal triangle is bounded by the tip of the coccyx, sacrotuberous ligaments, and a line connecting the right and left ischial tuberosities. It contains the anal canal, which pierced the levator ani muscle portion of the pelvic diaphragm. The urogenital triangle is bounded by the ischiopubic rami to the inferior surface of the pubic symphysis and a line connecting the right and left ischial tuberosities. This triangular space contains the urogenital (UG) diaphragm that transmits the urethra (in male) and urethra and vagina (in female). A. Anal Triangle Turn the cadaver into the prone position. Make skin incisions as on page 144, Fig. 5.4 of the Dissector. Reflect skin and superficial fascia of the gluteal region in one flap to expose the large gluteus maximus muscle. This muscle has proximal attachments to the posteromedial surface of the ilium, posterior surfaces of the sacrum and coccyx, and the sacrotuberous ligament. -

J Orthop Ther: JORT-139. DOI: 10.29011/JORT-139.000039 Received Date: 3 June, 2017; Accepted Date: 8 June, 2017; Published Date: 15 June, 2017 Abstract We provide an anatomical review of the femoral triangle, its application to the anterior surgical approach to the hip, and a useful mnemonic for remembering the contents and relationship of the femoral triangle. The femoral triangle is located on the anterior aspect of the thigh, inferior to the inguinal ligament and knowledge of its contents has become increasingly more important with the rise in use of the Smith-Petersen Direct Anterior Approach (DAA) to the hip as well as ultrasound and fluo- roscopic guided hip injections. A detailed knowledge of the anatomical landmarks can guide surgeons in their anterior approach to the hip, avoiding iatrogenic injuries during various procedures. The novel mnemonic “NAVIgate” the femoral triangle from lateral to medial will aid in remembering the borders and contents of the triangle when performing surgical procedures, specifically the DAA. -

You examine the patient and find her to be alert but pale and sweaty, with breathing that is rapid and shallow. You see that she has distension of her right internal jugular vein visible to the jaw and neck. Her trachea is deviated 3 cm to the right of midline. She has tender contu- sions on her left anterior chest wall with minimal active bleeding over one of the ribs. During the brief period of your examination, the patient exhibits more respiratory distress, and her blood pressure begins to drop. You urgently insert a large-gauge needle into her left hemitho- rax and withdraw 20 cc of air. This results in immediate improvement in the patient’s breath- ing and blood pressure. Why does the patient have a distended internal jugular vein on the right side of her neck? Could this be related to a rapid drop in blood pressure? What is the clinical situation of this patient? Hint: As you read this chapter, note that knowledge of normal surface anatomy is vital to the FIGURE: In order to effectively administer medical treatment, it is imperative for a recognition of abnormal surface anatomy, and that the latter may be an easy clue to the pathol- physician to know the surface anatomy of each ogy lying deep within the body. -

Ana Tomical Triangles J
43 ANA TOMICAL TRIANGLES J. LESLIE PACE, M.D. Department of Anatomy, Royal University of Malta Anatomical description is given of certain areas in the human hody which have :.l triangular sha!)e and which are of anatomical or surgical importance. There are at lea;,t 30 describe,d ,anatomical triangles, many of which receive eponymous names. Some are of nUlrked importance and well known e.g. Scarpa's femoral triangle, Hesselbach's inguinal triangle, H!ld Petit '5 lumbar triangle; others arc of relative1y minor importance and n.ot so well-known e.g. Elau's, Friteau's and Assezat's triangles. Anatomical trianlfles are described in various regions .of the body e.g. Macewen's ana Trautmann's in the head regiml, Beclaud's and PirDgoff's in the neck region, He'lSelbach '5, Henke '5, Petit's amI Grynfeltt's in the ,abdominal wall region and Searpa's Hnd Weber's in the lower limb Tf~gion. Their size varies, some being large e.g. Scarpa's triangle, others being very small e.g. Macewen's triangle.
