What are the soft tissues of the oral cavity?


What are the soft tissues of the oral cavity? The tongue, cheeks, gum, and lips are the soft tissues in the mouth. Each area is sensitive and contains a large number of blood vessels; hence whenever they are injured they bleed easily and profusely.

What type of tissue is in the oral cavity? The oral cavity is lined by a mucous membrane (the oral mucosa) consisting of a stratified squamous epithelium, which may or may not be keratinized, and an underlying connective tissue layer, the lamina propria.

What is the thinnest tissue in the oral cavity? According to its location within the oral cavity, the epithelium showed highest values in the region of the buccal mucosa (659.79 µm) and the thinnest one was observed in the mouth’s floor (100.07 µm).

What are hard and soft tissues? Hard tissue is usually referring to bones, while soft tissue refers to muscle, ligaments, tendons, or connective tissue. Hard tissue damage can affect any bone in the body, including the head or spine.

What is the difference between the vestibule and the oral cavity?

The oral cavity is arbitrarily divided into two parts: the oral cavity proper which is the region medial to the teeth that houses the tongue and the oral vestibule, which is the space that separates the lips and cheeks from the teeth.

What are the 3 types of oral mucosa?

Histologically, the oral mucosa is classified into three categories, lining, masticatory, and specialized.

What kind of tissue lines the insides of your cheeks?

The tissue that lines the inside of the mouth is known as the basal mucosa and is composed of squamous epithelial cells. These structures, commonly thought of as cheek cells, divide approximately every 24 hours and are constantly shed from the body.

What is the hardest tissue in the human body?

Enamel, in anatomy, the hardest tissue of the body, covering part or all of the crown of the tooth in mammals. Enamel, when mature, consists predominantly of apatite crystals containing calcium and phosphate. Enamel is not living and contains no nerves.

What type of epithelium is found in the lining of the oral cavity?

The type of epithelium that covers the lining mucosa is a non-keratinized stratified squamous epithelium [1]. The rigid mucosa tightly bound to the underlying bone in the attached gingiva and hard palate is known as masticatory mucosa.

What is hard tissue example?

Hard tissue (also termed calcified tissue) is tissue which is mineralized and has a firm intercellular matrix. The hard tissues of humans are bone, tooth enamel, dentin, and cementum. The term is in contrast to soft tissue.

What are the 2 main divisions areas of the oral cavity?

The oral cavity is surrounded by the lips and is composed of two separate regions, the vestibule, the area between the cheeks, teeth, and lips, and the oral cavity proper.

What are the two parts of the oral cavity?

The oral cavity includes the lips, hard palate (the bony front portion of the roof of the mouth), soft palate (the muscular back portion of the roof of the mouth), retromolar trigone (the area behind the wisdom teeth), front two-thirds of the tongue, gingiva (gums), buccal mucosa (the inner lining of the lips and

What is the main function of the oral cavity?

The oral cavity represents the first part of the digestive tube. Its primary function is to serve as the entrance of the alimentary tract and to initiate the digestive process by salivation and propulsion of the alimentary bolus into the pharynx.

What does a healthy oral mucosa look like?

Normal tissues of the buccal mucosa appear moist and pink/dark pink. They are soft and pliable on palpation with no discernible indurations. Stensen’s duct should be identified with or without the presence of a parotid papilla.

What color is oral mucosa?

Oral mucosa is generally pink in colour. Highly keratinized, firm, stippled and pale masticatory mucosa cover the hard palate, dorsal surface of tongue, and gingiva. Thin, less keratinized and more pinkish non-masticatory mucosa cover the remaining intra-oral structures.

Which type of oral mucosa covers the inside of the cheeks?

Nonkeratinized squamous epithelium covers the soft palate, inner lips, inner cheeks, and the floor of the mouth, and ventral surface of the tongue. Keratinized squamous epithelium is present in the gingiva and hard palate as well as areas of the dorsal surface of the tongue.

How long do cheek cells live?

Our cheek cells are an incredible reminder of how our body is constantly working and regenerating. Over the course of about 24 hours, cheek cells cells divide and regenerate. The old cells get shed from the body to make way for the new ones, displaying how quickly human cell regeneration can work.

What are the characteristics of your cheek cells?

This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape. Like most eukaryotic cells, this cell is very large compared to prokaryotic cells.

What is the strongest tissue in our body?

The enamel covering of our teeth also withstands extreme acid-base fluctuations, some of which come from various populations of bacteria that grow in our mouths. Overall, enamel is by far the toughest material in our bodies, and scientists have been examining its structure and composition for decades.

Which is the hardest part in teeth?

Tooth enamel is the hardest substance in the body.

The shiny, white enamel that covers your teeth is even stronger than bone. This resilient surface is 96 percent mineral, the highest percentage of any tissue in your body – making it durable and damage-resistant.

What is the strongest muscle in the body?

The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.

What is the difference between the oral mucosa and epithelium?

Even though both oral mucosa and skin are stratified epithelium, structural differences between these two sites do exist. The presence of hair follicles and sweat glands occurs in skin but not in mucosa, while taste buds are found in mucosa but not in skin.

What is the oral epithelium?

The oral mucosal epithelium is a barrier that separates the underlying tissues from their environment. It consists of two layers, the surface stratified squamous epithelium and the deeper lamina propria.

Is soft tissue cancerous?

Soft tissue sarcomas are cancerous (malignant) tumors that originate in the soft tissues of your body. This illustration shows a soft tissue sarcoma of the thigh muscle just above the knee. Soft tissue sarcoma is a rare type of cancer that begins in the tissues that connect, support and surround other body structures.

How bad is soft tissue damage?

As another factor – and one of the reasons Grade 3 injuries can end athletic careers – soft tissue injuries may permanently change the muscle, tendon or ligament. In turn, that body part may no longer function like it used to, which then affects how well an athlete performs.
