DIFFERENT VIEWS OF X-RAY FILMS-LESSON 133

-








In order to take the best possible view of the part of the body being radiographed, the patient, film, and x-ray tube must be positioned in the most favorable alignment possible. There are special terms used by radiologists to designate the position for direction of the x-ray beam, the patient's position, and the motion and position of the part of the body to be examined. Some of the important x-rays terms are as follows:
AP view or anteroposterior view: In this view the patient is usually supine i.e. lying on the back and the x-ray tube is aimed from above at the frontal side of the body and the beam is passed from the anterior to posterior. The film lies underneath the patient. The AP view may also be taken with the patient in the upright position.

PA view or posteroanterior view: In this view, the patient is upright with back to the x-ray machine and the film to the chest. The x-ray machine is aimed horizontally at a distance of about 6-feet from the film.
Lateral view: In this view, the x-ray beam passes from one side of the body toward the opposite side. In taking a right lateral view, the right side of the body is held closely against the x-ray film and the x-ray beam passes from the left to the right through the body.
Oblique view: In this view, the x-ray tube is positioned at an angle from the perpendicular plane. Oblique views are used to show regions that would be hidden and superimposed in routine AP and PA views.

BODY POSITION RELATED TERMS USED IN THE X-RAY EXAMINATION:
1. Abduction: Moving the part of the body away from the midline of the body or away from the body.
2. Adduction: Moving the part of the body toward the midline of the body or toward the body.
3. Eversion: Turning outward.
4. Extension: Lengthening or straightening a flexed limb.
5. Flexion: Bending a part of the body.
6. Inversion: Turning inward
7. Lateral decubitus: Lying down on the side with x-ray beam horizontally positioned. Another term for this is cross-table lateral.
8. Prone: Lying on the belly i.e. face down.
9. Recumbent: Lying down i.e. prone or supine.
10. Supine: Lying on the back i.e. face up.

Abdominopelvic Quadrants and Regions - Lesson 5

-
Abdominopelvic quadrants and regions are divided into 9 regions as per the division of the abdominal and pelvic cavities to explain the regions in which internal organs are found. They are as follows: Hypochondriac, epigastric, lumbar, umbilical, inguinal, and hypogastric. Now we will see about all abdominopelvic quadrants and regions one by one now. 1. Hypochondriac regions (2): The two upper right and left regions below the cartilage (chondr/o) of the ribs that extend over the abdomen. 2. Epigastric regions (2): This is the region above the stomach. 3. Lumbar regions (2): The two right and left regions near the waist part of the body. 4. Umbilical regions (1): The region of the umbilicus or navel portion of the body. 5. Inguinal regions (2): The two lower right and left regions of the body, inguin/o means groin that is the area where the two legs join together with the trunk of the body. This region is also called iliac regions because they are near the ilium part

Body Cells and Differentiation-Lesson 1

Body cells are different types. We often may read about stem cell types. Like in a movie there are many actors to do their different roles to establish a story, in our body there are different kinds of cells to do different roles to keep the body stable and active. The cells in our body are of two types: 1. Somatic cells. Our body contains Muscle cells, Nerve cells, Skin cells, and Fat cells. These kind of cells performing mainly body related functions and so they are called Somatic cells. There are varieties of cells inside the body. Every cell is different or specially created to do their special role inside the body throughout. Fat Cell: For example in body cells a FAT CELL has in it empty and large spaces for fat storage, and a muscle is slender and long and has in it fiber material that help in relaxing and contracting, as well as a skin cell is square in shape and also flat in structure to give protection to our body and a nerve cell which is long in struct
