Body Planes, Regions, Cavities, and Directional Terms

The fundamentals of learning the body in the medical field are body planes, regions, cavities, and directional terms. First up are the body planes, which the definition of a body plane is simply a two-dimensional surface. The dimensions of the body plane are both of length and of width and the body planes are used to describe the different locations that are located in the body or are just used for the point of location. There are three common planes that are used in medical practices. One is the sagittal plane, which is a vertical plane, or one that goes from top to bottom, that divides the body in half, right and left. Another plane is the coronal plane, which is also a vertical plane

These 2 regions are located on either side of the umbilical region and contain portions of the large and small intestines, and also the kidneys. Following the right and left lumbar regions, we have the umbilical region, which is the area around the umbilicus, or belly button, hence the name. The umbilical region includes sections of the large and small intestines, the inferior vena cava, and the abdominal aorta. After the umbilical region comes the right and left iliac region, which is on either side of the hypogastric region and inferior to the right and left lumbar regions. These regions include fractions of the large and small intestines. To round up the regions of the abdomen, there is the hypogastric region, which is located inferior to the umbilical region. This region of the abdomen contains parts of the sigmoid colon, the urinary bladder, the ureters, and portions of the small intestines. In women, this region contains the uterus and the ovaries. To follow the body regions, there are the body cavities. There are two main body cavities, which are the dorsal and the ventral cavities. The dorsal cavity is posterior of the body. This cavity contains both the cranial cavity and the spinal cavity. The …show more content…
The structure and function of the cell are very important to be able to carry on all forms and systems of life. The basics of the animal cell structure begin with the cell wall. The cell wall's function is to help protect the plasma membrane and it also plays an important role in not only supporting but protecting the cells, with its thick outer layer made out of cellulose. Next is the cell membrane, which is a double-layered, thin barrier. The cell membrane does a job of surrounding the cell to control both the entry and exit of specific substances. Up next is the cytoplasm, which is a membrane that defends the cell by keeping the cell organelles separate from each other. This structure of the cell helps keep the cell secure. The next cell structure is the nucleus. The nucleus is the membrane bound organelle, which is found in the all of the eukaryotic cells. This is a very important organelle, as it controls the complete activity of a cell. It also plays a key role in reproduction. Next up is the nuclear membrane, which is a bilayer membrane. This membrane guards the nucleus by surrounding around it and acting as a barrier between the cell nucleus and other organs of the cell. The nucleolus is the next cell structure that is going to be discussed. The nucleolus is a necessary membrane found inside the nucleus. It plays an important role in the production of the cell's membranes. Endoplastic reticulum follows, as it helps in
