Buccal Cavity Research Paper

The oral cavity enabled us to identify and locate the following: the hard palate, the soft palate, the tongue, and the taste buds. This procedure taught us that mammals have two types of teeth, incisors located in the front and cheek teeth located in the back of the oral cavity. We were also asked to locate the

1. Oral cavity, pharynx, (must also include accessory organs such as salivary glands, tongue, and teeth)

Consist of oral cavity, esophagus, gallbladder, liver, stomach, duodenum, pancreas, colon, cecum, appendix, jejunum, and rectum.

Further back is a set of posterior cheek teeth also capable in shearing and processing food.

Also known as the oral cavity. Another opening of the respiratory system and can also take air in and out

As you can see, it is a tubelike structure made of muscle and lined with mucous membrane. The pharynx functions as part of the respiratory and digestive system because it is located behind the nasal cavities and the mouth. It is the structure that we refer to as the throat. It is about twelve and a half centimeters long and consists of three parts; the nasopharynx, oropharynx and the laryngopharynx. (Anatomy.tv, n.d.) The esophagus branches off of the pharynx which carries food to the stomach. Swallowing takes place in the pharynx partly as a reflex and partly under voluntary control. The tongue and soft palate pushes food into the pharynx, which closes off the trachea. The food then enters the esophagus. The esophagus is a muscular tube extending from the pharynx to the stomach. . (Mohan, 2010). It is about 25 centimeters long. The production of mucus by glands in the mucosal lining as you can see lubricates the tube to permit easier passage of food moving toward the stomach. (Thibodeau & Patton, 2008). Food is pushed through the esophagus and into the stomach by a series of contractions called peristalsis. The lower esophageal sphincter is just before the opening to the stomach. It opens to let food pass into the stomach and closes to keep it there. (Mohan, 2010).

Unlike human saliva, this mucus does not contain digestive enzymes, and only purpose is to aid the process of swallowing. The food then progresses into the pharynx, where the gill clefts are located. The pharynx acts as a passageway between the mouth and the oesophagus. Constructed of two layers of non-striated muscle, the oesophagus carries the food through to the gizzard, making use of mucus cells which assist in this process. Digestion begins in the gizzard, as it is a muscular modification of the first section of the stomach. The gizzard grinds coarse foods into smaller pieces, and secretes digestive enzymes into the

Mouth:-It contains the teeth, gums, soft palate, hard palate, the tongue and the lip. The soft and hard palate`s functions of prevent the large pieces to enter the body and mainly separate from trachea and esophagus. The tongue is where the saliva is mixed with enzymes and watery content to moist the food and allow the movement during mastication. The teeth breaks down food.

Wisdom teeth are a third set of molars; they are large, extraneous, impacted teeth that sometimes have to come out. Around the tenth birthday the last set of molars begin forming. These teeth are the last set of teeth to come in and do not erupt until the ages of 17 and 25. Although, some individuals have them appear many years later. The nickname “wisdom teeth,” comes from the belief that people are wiser around these ages.

I chose the oral cavity to describe for this discussion board. The oral cavity ingests, chews, and swallows the food so that it may enter our bodies. The oral cavity is the place where digestion begins. Before it goes anywhere in the body it has to enter our mouths first so that it may be mechanically broken down with the help of our teeth and saliva. Saliva contains digestive enzymes that help break down the food particles so that it's easier for us to swallow. Hanging at the back of the throat is the uvula which is there to serve for more than one purpose. The first purpose being it has a role in speech production, and the second one being the gag reflex. The reflex is stimulated when food enters the throat without swallowing. This prevents

Attachment points for the muscles of the head and neck are located on the exterior surfaces of the skull and allow for important movement like chewing, speech, and facial expressions. Teeth are rooted into deep sockets in the mandible and maxillary bones. The upper portions of the digestive and respiratory tracts are also housed within the hollow oral and nasal cavities of the skull.

the tissues above the upper jaw or between the nose and the upper corner of the lip and

Additionally, the jaw muscles: masseter, temporalis, medial pterygoid, and the lateral pterygoid are involved in mechanical digestion. The change of tooth size also influenced the jaw muscles’ length. The primary function of the jaw muscles is to aid the process of breaking down food into smaller particles to make food digestion more effortless. As the size of teeth decreased, the amount of

Inside your mouth is what is known as your tongue and it has the job of pushing around your food while you chew, in order to help out with the process. Once you have completely dissolved the food and are prepared to swallow what is at this point known as bolus, your tongue pushes it to the back of your throat and into the opening of your esophagus.
