Tissue Quiz

B: Mesothelium is simple squamous epithelium that is found in serous membranes.

B: Epithelial is a major tissue type (as is muscle, nervous and connective).

C: Pleura is around the lungs, while visceral refers to the layer of the pleura that is attached to the lung surface. Dura mater is a membrane that surrounds and protects the brain.

C: “Intercellular” means between cells. Matrix is composed of fibres and ground substance (but no cells).

D: Melanocytes produce melanin to protect the skin from ultraviolet radiation, and it results in tanning of the skin.

A: Tendons and ligaments are dense connective tissue. This is strong as there is a high proportion of fibres.

D: The lamina propria is a “basement membrane” attached to epithelial tissue. The others are serous membranes.

C: Keratinocytes produce keratin, the protein of the epidermis, which is epithelial tissue.

D: Adipocytes are found in fat (adipose tissue) which is a type of connective tissue.

D: The word “simple” indicates a single layer of cells. Stratified means several layers (or strata) of cells.

D: The epidermis (on top of the dermis) is epithelial tissue.

B: Glandular tissues are one type of epithelial tissue, and their function is to produce material to secrete.

A: Simple = one layer. Columnar means oblong or shaped like a column.

A: This is a definition of epithelial tissue.

C: Mucosa is a mucous membrane (and secretes mucus).

A: The names of the cells contain a description of their shape: either flat or like columns. Simple refers to a single layer of cells.

D: These cells produce keratin, the protein of the stratum corneum.

A: Epithelial tissue has one surface “open” to the exterior or to the contents of the tube.

C: Keratinocytes are in the epidermis which is epithelial tissue. The other cell types occur in fat, cartilage and bone.

A: Being close packed is a property of epithelial tissue. In connective tissues the cells are widely spaced, being separated by the ground substance.

C: Chondro- refers to cartilage, so chondrocytes are cells found in cartilage. Cartilage is a connective tissue. The other choices are found in epithelial tissue, or nervous tissue.

D: These are the four types. Extracellular fluid is not a tissue. Cartilage is a type of connective tissue.

A: Deep fascia is a fibrous connective tissue that surrounds and penetrates into the muscles, as well as surrounding bones, nerves and blood vessels._x000d_Muscle epimysium is an example of deep fascia. Choice C is referring to superficial fascia.

D: Blood contains cells separated by a liquid matrix. Choices A and B are epithelial and nervous tissues.
