Planes, Regions, and Quadrants Planes, Regions, and Quadrants •Anatomy – Shape and structures of an organism’s body and the relationship of one body part to another •Physiology – Function of each body part and how the functions of the various body parts coordinate to form a complete living organism In Anatomical Position, the body is assumed to be standing, the feet together, the arms to the side, and the head and eyes and palms of the hands facing forwards. Anterior or ventral – Front or in front of Posterior or dorsal – Back or in back of Cranial and caudal – Refer to direction of either toward the “head end” or “tail end” Superior and inferior – Above or below another Medial and lateral – Toward the midline or away from the midline Proximal and distal – Toward or away from the point of attachment or origin Superficial or external – On or near the surface or deep (internal) Sagittal plane – Right and left parts Midsagittal plane – Equal right and left parts Coronal (frontal) plane – Vertical at right angles to the sagittal plane Transverse or cross section – Horizontal; divides body into upper and lower parts Left Upper Quadrant (LUQ) - One of the four quadrants that the abdominopelvic area can be divided into. Located in the left upper portion of the abdomen it includes a view of the stomach, spleen, the left kidney, and parts of the duodenum, pancreas, left ureter, small intestine, and transverse and decending colon. Left Lower Quadrant (LLQ) - One of the four quadrants that the abdominopelvic area can be divided into. Located in the left lower portion of the abdominopelvic area and provides partial views of the small intestine, descending and sigmoid colon, rectum, left ureter, and urinary bladder. Right Lower Quadrant (RLQ) - One of the four quadrants that the abdominopelvic area can be divided into. Located in the right lower portion of the abdominopelvic area and includes a view of the appendix, cecum, and partial views of the ascending colon, small intestine, right ureter, urinary bladder, and rectum. Right Upper Quadrant (RUQ) - One of the four quadrants that the abdominopelvic area can be divided into. Located in the right upper portion of the abdomen it provides a view of the gallbladder, most of the liver, and partial views of the pancreas, small intestine, and ascending and transverse colon. Dorsal cavity – Brain and spinal cord – Cranial cavity – Spinal cavity Thoracic cavity Abdominopelvic cavity – Abdominal cavity – Pelvic cavity Epigastric region (upper) – Just below sternum Right and left hypochondriac – Just below ribs Umbilical (middle) – Located around the navel Right and left lumbar – Extend from anterior to posterior Hypogastric (lower) – Pubic area Right and left iliac – Also called right and left inguinal areas Do you know what the ant abbreviations on the AP right stand for?

Anatomy of the Dog – Fully illustrated with color line diagrams, including unique three-dimensional cross-sectional anatomy, together with radiographs and ultrasound scans – Includes topographic and surface anatomy – Tabular appendices of relational and functional anatomy “A region with which I was very familiar from a surgical standpoint thus became more comprehensible. […] Showing the clinical rele- vance of anatomy in such a way is a powerful tool for stimulating students’ interest. […] In addition to putting anatomical structures into clinical perspective, the text provides a brief but effective guide to dissection.” vet vet The Veterinary Record “The present book-atlas offers the students clear illustrative mate- rial and at the same time an abbreviated textbook for anatomical study and for clinical coordinated study of applied anatomy. Therefore, it provides students with an excellent working know- ledge and understanding of the anatomy of the dog. Beyond this the illustrated text will help in reviewing and in the preparation for examinations. For the practising veterinarians, the book-atlas remains a current quick source of reference for anatomical infor- mation on the dog at the preclinical, diagnostic, clinical and surgical levels.” Acta Veterinaria Hungarica with Aaron Horowitz and Rolf Berg Budras (ed.)

  • The Digestive System
    69 chapter four THE DIGESTIVE SYSTEM THE DIGESTIVE SYSTEM The digestive system is structurally divided into two main parts: a long, winding tube that carries food through its length, and a series of supportive organs outside of the tube. The long tube is called the gastrointestinal (GI) tract. The GI tract extends from the mouth to the anus, and consists of the mouth, or oral cavity, the pharynx, the esophagus, the stomach, the small intestine, and the large intes- tine. It is here that the functions of mechanical digestion, chemical digestion, absorption of nutrients and water, and release of solid waste material take place. The supportive organs that lie outside the GI tract are known as accessory organs, and include the teeth, salivary glands, liver, gallbladder, and pancreas. Because most organs of the digestive system lie within body cavities, you will perform a dissection procedure that exposes the cavities before you begin identifying individual organs. You will also observe the cavities and their associated membranes before proceeding with your study of the digestive system. EXPOSING THE BODY CAVITIES should feel like the wall of a stretched balloon. With your skinned cat on its dorsal side, examine the cutting lines shown in Figure 4.1 and plan 2. Extend the cut laterally in both direc- out your dissection. Note that the numbers tions, roughly 4 inches, still working with indicate the sequence of the cutting procedure. your scissors. Cut in a curved pattern as Palpate the long, bony sternum and the softer, shown in Figure 4.1, which follows the cartilaginous xiphoid process to find the ventral contour of the diaphragm.

(ECA): pp. 118 and 135­141 Grant's Atlas Figures listed at the end of this syllabus. OBJECTIVES:Today's lectures are designed to explain the orientation of the abdominopelvic viscera, the peritoneal cavity, and the mesenteries. LECTURE OUTLINE ­ PART 1 I. The abdominopelvic cavity contains the organs of the digestive system, except for the oral cavity, salivary glands, pharynx, and thoracic portion of the esophagus. It also contains major systemic blood vessels (aorta and inferior vena cava), parts of the urinary system, and parts of the reproductive system. A. The space within the abdominopelvic cavity is divided into two contiguous portions: 1. Abdominal portion ­ that portion between the thoracic diaphragm and the pelvic brim a. The lower part of the abdominal portion is also known as the false pelvis, which is the part of the pelvis between the two iliac wings and above the pelvic brim. Sagittal section drawing Frontal section drawing 2. Pelvic portion ­ that portion between the pelvic brim and the pelvic diaphragm a. The pelvic portion of the abdominopelvic cavity is also known as the true pelvis. B. Walls of the abdominopelvic cavity include: 1. The thoracic diaphragm (or just “diaphragm”) ­ located superiorly and posterosuperiorly (recall the dome­shape of the diaphragm) 2. The lower ribs ­ located anterolaterally and posterolaterally 3. The posterior abdominal wall ­ located posteriorly below the ribs and above the false pelvis and formed by the lumbar vertebrae along the posterior midline and by the quadratus lumborum and psoas major muscles on either side 4.
