Epithelial cells are the building blocks of epithelial tissue. Like every other cell, they are surrounded by cellular membranes. Epithelial cell membranes have three regions (domains) different in structure and function; apical, lateral and basal.
Surface epithelium consists of one or more cell layers, stacked over a thin basement membrane. Based on the cell shape, epithelial tissue is classified into squamous, cuboidal or columnar. Depending on the number of layers, the tissue is divided into simple or stratified. Subclassifications include pseudostratified, ciliated or transitional.
Bodytomy provides a labeled diagram to help you understand the structure and function of simple columnar epithelium. Did You Know?

Structure of Bone Tissue. There are two types of bone tissue: compact and spongy. The names imply that the two types differ in density, or how tightly the tissue is packed together. There are three types of cells that contribute to bone homeostasis.
A typical long bone shows the gross anatomical characteristics of bone. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone. Red marrow fills the spaces in the spongy bone.
Compact bone is the denser, stronger of the two types of bone tissue ( (Figure) ). It can be found under the periosteum and in the diaphyses of long bones, where it provides support and protection. (a) This cross-sectional view of compact bone shows the basic structural unit, the osteon.

Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. It is made up of thin and elongated cells called muscle fibers.

Last Updated: Jul 16, 2019 The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.
