We discuss the superficial layer of skin, the epidermis, including its accessory structures i.e. glands, nerves, cell types, and tissue types.

We discuss an introduction to the integumentary system (your skin), including the epidermis and dermis, as well as the hypodermis.

We discuss the process of tissue injury (inflammation and regeneration) and the effects of aging on tissues.

We briefly review the types of nerve tissue, including neurons and glial cells.

We briefly review the three types of muscle tissues (skeletal, cardiac, and smooth).

We discuss the other types of connective tissues, fluid (blood and lymph), and supporting (bone and cartilage). We further discuss the three types of cartilage: hyaline, elastic, and fibrocartilage.

We discuss the types of connective tissue proper, including loose (reticular, adipose, areolar) and dense (regular, elastic, irregular) connective tissue proper.

We discuss the connective tissues of the body, including loose connective tissue proper (reticular, areolar, adipose), and dense connective tissues proper (regular, irregular, and elastic).

We discuss the different types of epithelial glands, including eccrine, apocrine, and holocrine glands.

We review epithelium classifications, including simple and stratified categories of squamous, cuboidal, and columnar epithelium. We also discuss pseudostratified ciliated columnar epithelium and transitional epithelium.
