What Are Branches And Thies Affect The Skins Of Human Skin

➢ After leaving the pharynx, air enters the ;larynx, where two pairs of ligaments, together with the mucosa covering them, forms the vestibular and vocal folds. These folds help prevent foreign particles, including food, from entering the lower respiratory system.

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

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

The face should consist of cut-out sections. These can be sections for the eyes, nose, and mouth for example.

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

In the article “Skin Pathology in the Cretaceous: Evidence for Probable Failed Predation in a Dinosaur” written by Brice M. Rothschild and Robert Depalma, they report their findings on the observation of the skin of a duck billed dinosaur regarding its’ scaled pattern and forming of scar tissue (Rothschild and Depalma 2013). Rothschild and Depalma introduce the issue of dinosaur skin pathology through the finding of damaged dinosaur skin through Lingham-Soliar ‘s (2008) report on the damaged skin and bite impression of the Psittacosaurus skin, which did not heal from the bite; indicating that the Psittacosaurus had died from either a scavenger or a predator (Rothschild and Depalma 2013). However Rothschild and Depalma (2013) focus their research

The name of the above diagram is called the Buccal Cavity. I am going to talk about each labelled structure in detail.

shape of our face is the shape of our skull, our lips retreat back from

The epiglottis is a flap that is made of elastic cartilage tissue covered with a mucous membrane, attached to the entrance of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally. There are taste buds on the epiglottis.

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.

Folds running from the mouth to the chin and/or the nose to the mouth (melolabial and nasolabial folds)

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.

Stratum Corneum this layer is the outer most layers; it is formed from numerous layers of compressed scale- like, overlapping cells. What makes up the surface of the skin is corneocytes, which are commonly called ‘dead skin cells’. Keratinocytes are found in the epidermis they travel up through the layer where they are formed into corneocytes. The stratum corneum layer protects against lights, chemicals, water loss, heat and bacteria.
