Examples include the superior and inferior vena cava, which carry deoxygenated blood away from the head superior and from the lower body inferior to the heart. Umbilical The umbilical region contains the umbilicus navel , and many parts of the small intestine, such as part of the duodenum, the , and the illeum. Vertebral The vertebral cavity is the posterior portion of the dorsal cavity and contains the structures within the vertebral column. This includes the limbs and appendages. The abdomen and its external surface, divided into nine regions by four imaginary planes: two horizontal, one at the level of the ninth costal cartilage or the lowest point of the costal arch and the other at the level of the highest point of the iliac crest; two vertical, through the centers of the inguinal ligaments or through the nipples or through the centers of the clavicles or curved and coinciding with the lateral borders of the two abdominal rectus muscles.
These quadrants are defined by the intersection of the saggital plane with the umbilical plane the through the navel. Left Iliac : Small intestine, descending colon, sigmoid colon; F- left ovary, left Fallopian tube. The Upper Abdomen Now let's explore the three regions of the upper abdomen. Most organs are part of multiple regions, including the gallbladder, duodenum, stomach, kidneys, spleen, small intestine and colon. Anatomists and medical personnel divide the abdominopelvic cavity into smaller regions to facilitate study and discussion. In this position, a person is standing upright with the lower limbs together or slightly apart, feet flat on the floor and facing forward, upper limbs at the sides with the palms facing forward and thumbs pointing away from the body, and head and eyes directed straight ahead. The perineum the area beneath the hypogastric region at the bottom of the pelvic cavity is sometimes considered to be a tenth division in this system.
Right Iliac The right iliac region contains the appendix, cecum, and the right iliac fossa. These divisions are often used to categorize the individual abdominal organs by their location and function and are used by clinicians to help diagnose the source of abdominal pain and determine appropriate treatment. The adrenal glands and the first part of the small intestine, the duodenum, are also found in region 2. Serous membranes secrete a watery lubricating fluid Select the most correct statement A. This region pushes out when the diaphragm contracts during breathing.
Right Iliac The right iliac region contains the appendix, cecum, and the right iliac. Dorsal The dorsal cavity is a continuous cavity located on the dorsal side of the body. The perineum the area beneath the hypogastric region at the bottom of the pelvic cavity is sometimes considered to be a tenth division in this system. Cytology: study of structures in a particular region D. It means that someone is totally preoccupied with minor health or physical symptoms that have no real underlying illness or disease. In humans, the standard anatomical position of the skull is called the Frankfurt plane.
The most common divisions for the abdominopelvic region are the four quadrants and nine regions. On the other hand, despite the name, those with antisocial personality disorder are not always antisocial; they can actually be rather talkative people. Left Lumbar The left lumbar region consists of the descending colon, the left kidney, and part of the spleen. Umbilical The umbilical region contains the umbilicus navel , and many parts of the small intestine, such as part of the duodenum, the jejunum, and the illeum. When looking at the abdomen from the front of the body, it can be broken down into nine main regions, almost like a criss-cross board with lines running both horizontally and vertically.
Pain in this region is generally associated with colitis inflammation of the large intestine as well as pelvic inflammatory disease and ovarian cysts in females. Anatomical terminology for body cavities: Humans have multiple body cavities, including the cranial cavity, the vertebral cavity, the thoracic cavity containing the pericardial cavity and the pleural cavity , the abdominal cavity, and the pelvic cavity. To flip the current card, click it or press the Spacebar key. A Cytology: study of the structures in a particular region. When describing appendages, the proximal end of the appendage connects the appendage to the body, while the distal end is away from the body.
The X, Y, and Z axes of the Cartesian coordinate system are used describe the specific location of an axis in standard anatomical position. For example, the outer layers of skin are superficial to deeper layers of skin. These include bladder, part of the sigmoid colon, the anus, and many organs of the reproductive system, such as the uterus and ovaries in females and the prostate in males. B Blood glucose levels are regulated by positive feedback mechanisms. It houses the primary organs of the cardiovascular and respiratory systems, such as the heart and lungs, but also includes organs from other systems, such as the esophagus and the thymus gland. In comparative embryology, body planes provide a basis for comparing the ways in which different types of organisms develop anatomically within the womb. Cranial The cranial cavity is the anterior portion of the dorsal cavity consisting of the space inside the skull.
Positive feedback mechanisms always result in excessive damage to the host B. Proximal refers to a point closer to the reference point while distal refers to a point farther away. A Negative feedback mechanisms work to prevent sudden severe changes within the body. Regions 1-3 comprise the upper abdomen, regions 4-6 are the middle abdomen, and the regions 7-9 make up the lower abdomen. Visceral pericardium covers the surface of the heart, and parietal pericardium lines the walls of the heart D.
Right Hypochondriac : Liver, gall bladder, small intestine, ascending colon, transverse colon, right kidney. D The endocrine system is not a true structural organ system. This is the most narrow of all body cavities, sometimes described as threadlike. In the lower abdomen, we have the right iliac fossa, hypogastric, and left iliac fossa regions. Overview of the Abdomen Have you ever played tic-tac-toe? C Organ systems can be composed of cells or tissues, but not both.
