Mouth Palates Essay

1097 Words5 Pages

During the development of the mouth palate, two palate formations can be differentiated, namely the Primary palate and the Secondary palate. The purpose of the palates is to provide a division between the oral and the nasal cavities. Primary palate: Between the embryological period of week six and seven, formation of the primary palate takes place. The primary palate develops due to the merging of the medial and lateral nasal prominences with each other, and then the merging of the maxillary and the medial nasal prominences which pinches an epithelium layer which gives rise to the superior nasal epithelium and the inferior oral epithelium. The core of the primary palate is formed by the two epithelium layers mentioned above. The two layers …show more content…

The short oesophagus will grow quickly with the all over growth of the embryo. Splanchnic mesenchyme surrounds the oesophagus. The upper two-thirds of the oesophagus are striated and innervated by the vagus nerve. However, the lower third is smooth and is innervated by the splanchnic plexus. Stomach: During the 4th week of development the stomach appears. It appears first as a fusiform dilation of the foregut. The stomach undergoes certain rotations during its growth. When describing the rotations below, imaginary vertical and anteroposterior axis are used. First rotation: 90° clockwise This rotation occurs around the imaginary vertical axis. It results in the left side of the stomach changed to an anterior position and the right side in a posterior position. This also leads to a change in the innervation. The left vagus nerve innervates the left anterior stomach wall and the right vagus nerve innervates the right posterior stomach wall. During the 5th week the posterior wall keeps on growing and leads to the greater and lesser curvatures of the stomach. It develops because the dorsal border grows faster than the ventral

Entering the through the Lower esophageal Sphincter (LES) wasn’t entertaining but once you get in it’s like rippled effect of the water except that is a combination of red and pink. We’re finally in the stomach we will just hang in here an hour or two. Once we travel through the Rugae it will produce the enzyme Pepsin. So I can be prepared for the small intestine. First we will be going to the small intestine but first we will go to the duodenum.

Empathy Belly Project I underwent several discomforts and sensations while doing the empathy belly project. One of which was restricted breathing caused by the tightness of the belly which wasn’t enjoyable. Also the baby’s “feet” were sticking into my ribs, creating irritation when I walked or moved around a lot. I felt more fatigue with the belly on than I normally do since I exerted more energy trying to do everyday things thanks to the extra weight and figure. While buttoning my jacket and tying my shoes, I felt a little annoyed because it was more difficult to do than I thought it would be since I couldn’t look over my stomach.

The primary phases of the gastrointestinal tract of a horse include the foregut, which incorporates the mouth, esophagus, stomach, and small intestines. The adventure starts when the horse utilizes its teeth to tear grass from the earth or uses its lips to get bits of hay or grain starting from the earliest stage. The nourishment is exchanged to the back of the mouth by the tongue for biting by the molars and is blended with saliva. The blending of the sustenance with spit is the initial phase in the digestive procedure. Once the nourishment is chewed, the base of the tongue pushes it past the soft palate and into the pharynx.

The nasal septum bisects the nasal cavity and comprises three portions: the bony perpendicular plate of the ethmoid (superoanterior) and the vomer (posterior and anteroinferior), a cartilaginous anterior triangle, and an inferior membranous columella that divides the nares anteriorly. Laterally, the nasal wall has three or more horizontal ridges termed turbinates, with a corresponding meatus below each (Figure 1.4). During the sixth week of embryologic development, before cartilage forms in the walls of the primitive nasal cavities, linear outgrowths of the lining epithelium occur on the sides and roof of each nasal side. Each outgrowing gutter becomes a meatus, whereas the ridges left behind form the turbinates.8,16 The inferior turbinate is the largest, arising from the medial wall of the maxillary sinus.

As some may or may not know, a person 's tongue can show a lot about one 's health status.

The food then travels into the oesophagus. Your oesophagus is located near your trachea (windpipe). The epiglottis separates the nasal cavity and the lower airway from the passage of food whilst swallowing. The contractions of the muscles in your oesophagus push the food down your oesophagus and into your stomach. Your stomach is a hollow organ that holds food whilst it is being broken down by the enzymes.

Relations with the diaphragm and heart liver supplement neighboring organs. The base of the liver opens into the hepatic hilum, which is but the entrance area of the omentum (omentum) lower with the portal vein, hepatic artery and hepatic duct outlet. The omentum (omentum) lower (fixed at a protrusion of the lower side omental called tuber) lining the bottom of the grooves of the base of the liver (venous ligament sulcus, groove round ligament) and reaches the rear edge of the bottom face where the peritoneum overlying coating passes the diaphragm and the back wall forming hepatorenal ligament. Ahead of the peritoneum lining the diaphragmatic surface to its upper limit, where jumps take the abdominal surface of the diaphragm. Between the two folds of peritoneum onto the surface of the liver to the diaphragm is comprised bare surface of the liver, an area in which the peritoneum covering the liver capsule.

You know how gum commercials always boast that their product can give you a fresher, cleaner mouth, well, that’s not entirely a lie. But is chewing gum good for your teeth? When we eat, little bits of food get stuck between our teeth or behind those permanent retainers that a lot of people have these days. If that food gets to hang out long enough, it will become a breeding ground for bacteria. That bacteria can lead to cavities and infections, and really, isn’t an infection in the main hole in your face that’s pretty close to your brain about the last thing you want?

The digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment.
