Anatomical Directional Terms and Body Planes

body planes and directional terms

Regions and Quadrants of the Peritoneal Cavity. Directional Terms Applied to the Human Body. A plane is an imaginary two-dimensional surface that passes through the body. Anatomical planes are hypothetical flat surfaces that go through the body dividing it into sections. Ipsilateral means on the same side—the left arm is ipsilateral on the same side to the left leg. Your intestines are posterior to your abdominal muscles.

The pleura is the serous membrane that surrounds the lungs in the pleural cavity; the pericardium is the serous membrane that surrounds the heart in the pericardial cavity; and the peritoneum is the serous membrane that surrounds several organs in the abdominopelvic cavity. If it divides the body into unequal right and left sides, it is called a parasagittal plane or less commonly a longitudinal section. Anatomical directions help avoid confusion, prevent further injury and prevent mistakes. The three basic planes intersect at right angles to each other. Some examples include the anterior and posterior , superior and inferior , the median cerebral artery, and the axial skeleton. Anatomical position and directional terms The healthcare industry has its own terminology, especially anatomy and physiology. Both cavities are bound on the back by the spine.

The muscles are deep to the skin, and the skin is superficial to the kidneys. Anatomical Position To further increase precision, anatomists standardize the way in which they view the body. In directional terms, the coronal plane creates anterior and posterior body sections. The serous fluid produced by the serous membranes reduces friction between the walls of the cavities and the internal organs when they move, such as when the lungs inflate or the heart beats. In directional terms, body structures toward the midsagittal plane tend to be medial while structures farther away tend to be distal.

Understanding anatomical directional terms and body planes will make it easier to study anatomy. As you read the examples, look at Figure above to see the location of each structure. Affixes word parts that are attached to base words are also useful in describing the position of anatomical structures. Your femur bone in your upper leg would be proximal to your ankle bones tarsals. These terms are essential for describing the relative locations of different body structures. Palmar describes the palm side of the hand. Body Regions Body regions describe areas of the body that have a special function or are supplied by specific blood vessels or nerves.

The regions are named below and the corresponding regions are labeled 1-9. A deep wound is going to penetrate far below the surface of the skin! Also, an increase in volume of the abdominal cavity decreases the volume in the thoracic cavity—you can take in less air. The parietal layers of the membranes line the walls of the body cavity pariet- refers to a cavity wall. The next pair of directional terms relate to the front or back of the body or structure, relative to another structure. Directional Terms Applied to the Human Body.

Anatomical Planes of the Body Fans of horror films will understand how the anatomic planes divide the body because scary movies love to show the scary effect. The upper limbs are held out to each side, and the palms of the hands face forward as illustrated in. We strive for 100% accuracy, but nursing procedures and state laws are constantly changing. In order to provide exquisite care and understand the inner workings of the human body, anatomical terminology is a necessity. The word ventral literally means belly! In the pleural cavities, pleural fluid prevents friction between the lungs and the walls of the cavity. The image above shows how the body is cut into corresponding planes.

Prone describes a face-down orientation, and supine describes a face up orientation. Even though their location is defined, the shape of these cavities can change. The feet are spaced slightly apart with the toes pointing forward. The serous membranes form fluid-filled sacs, or cavities, that are meant to cushion and reduce friction on internal organs when they move, such as when the lungs inflate or the heart beats. Dorsal describes the back side of the hand.

The ventral cavity includes the thoracic and abdominopelvic cavities and their subdivisions. Body planes and sections For anatomical purposes, the body is often sectioned into flat surfaces called planes. The most widely used terms are those that describe the 9 abdominal regions shown in the image to the right. Your fingers phalanges would be distal to your wrist bones carpals. In order to describe body parts and positions correctly, the medical community has developed a set of anatomical positions and directional terms widely used in the healthcare industry. When the three basic planes intersect in the center of the body as seen in the image to the right they can be used to describe various relationships within the body. An oblique plane can be at any angle that is between the horizontal and vertical planes.
