Fundamentals of Oral Anatomy and Tissue Types Quiz

Keratinised stratified squamous epithelium is a type of tissue that is tough and waterproof, making it ideal for protecting the underlying layers from abrasions and water loss. It is commonly found in the epidermis of the skin.

Filiform papillae are the most numerous type of papillae found on the human tongue and do not contain taste buds. Fungiform, circumvallate, and foliate papillae contain taste buds and are involved in the sense of taste.

The hard palate is the bony front part of the roof of the mouth, the soft palate is the soft, flexible back part, the epiglottis is a flap of tissue that prevents food from entering the windpipe during swallowing, and the uvula is the dangly piece of tissue at the back of the throat.

Desmosomes and hemidesmosomes are specialized structures that help in cell-cell adhesion and attachment to the extracellular matrix. Gap junctions and tight junctions are involved in intercellular communication and barrier formation, respectively. Lysosomes, endosomes, ribosomes, and Golgi apparatus are cellular organelles with different functions unrelated to cell adhesion.

The sulcus terminalis is a groove on the dorsal surface of the tongue where the circumvallate papillae are located, making it the correct answer. The other options are not anatomical structures associated with the sulcus terminalis.

The correct answer refers to the gingival epithelium, which can be either free (unattached) or attached to the tooth structure. Toothpaste, dental floss, and mouthwash are not examples of structures that can be described as free or attached in the context of dental anatomy.

The question asks for the specific type of epithelium that fits the description of being non-keratinised, stratified, and composed of three layers. The correct answer, non-keratinised stratified squamous epithelium, matches these criteria perfectly, making it the right choice. The other three options do not align with the given characteristics, hence they are incorrect.

Taste buds are sensory organs on the tongue that allow individuals to perceive different flavors. They are not related to nose hair, eye sockets, or ear lobes.

Keratinocytes are the predominant type of cells in the epidermis, responsible for producing keratin. Melanocytes, on the other hand, are responsible for producing melanin, the pigment that gives skin its color. Fibroblasts are connective tissue cells, macrophages are immune cells, and lymphocytes are a type of white blood cell, none of which are non-keratinocytes.

The arrow is indicating the reticular ridges and connective tissue papillae in the skin. Rete ridges are the downward projections of the epidermis into the dermis, while connective tissue papillae are the upward projections of the dermis into the epidermis.
