What is not one of the main tissue types found in the human body? | Myocardial |
These types of cell junctions anchor adjacant cells together and resist their separation during contractile activities. | adherens junctions and desmosomes |
The thin extracellular layer, consisting of the basal and reticular lamina that anchors epithelial cells to underlying connective tissue is called the? | basement membrane |
Epithelial tissue | EVERYTHING! |
This type of epithelial tissue is found lining the heart, blood vessels and lymphatic vessels. | simple squamous |
This type of epithelial tissue forms the most superficial layer of the skin | stratified squamous |
This type of epithelial tissue lines the ducts of sweat glands and esophageal glands. | Statified cuboidal |

in which of the following locations would you most likely find transitional epithelial cells? | lining of the urinary bladder |
what glands are categorized by whether their ducts are branched or unbranched? | multicellular exocrine glands |
This type of multicellular exocrine gland has a branched rounded secretory part attached to a single unbranched duct and is found mainly in sebaceous glands. | simple branched acinar gland |
simple tubular exocrine glands have | a straight tubular secretory portion attached to a single unbranched duct. |
functional classification of exocrine glands is based on | how the glands release its secretory product |
This type of exocrine gland accumulates its secretory product in the cytosol of its cells until the cell ruptures and becomes part of the secretory product. | Holocrine |
