Identify the four types of tissue in the body, and describe the major functions of each tissue.

The zygote is described as totipotent because it ultimately gives rise to all the cells in your body including the highly specialized cells of your nervous system. Describe this transition, discussing the steps and processes that lead to these specialized cells.

What is the function of synovial membranes?

The structure of a tissue usually is optimized for its function. Describe how the structure of individual cells and tissue arrangement of the intestine lining matches its main function, to absorb nutrients.

One of the main functions of connective tissue is to integrate organs and organ systems in the body. Discuss how blood fulfills this role.

Why does an injury to cartilage, especially hyaline cartilage, heal much more slowly than a bone fracture?

You are watching cells in a dish spontaneously contract. They are all contracting at different rates; some fast, some slow. After a while, several cells link up and they begin contracting in synchrony. Discuss what is going on and what type of cells you are looking at.

Aspirin is a non-steroidal anti-inflammatory drug (NSAID) that inhibits the formation of blood clots and is taken regularly by individuals with a heart condition. Steroids such as cortisol are used to control some autoimmune diseases and severe arthritis by downregulating the inflammatory response.

As an individual ages, a constellation of symptoms begins the decline to the point where an individuals functioning is compromised. Identify and discuss two factors that have a role in factors leading to the compromised situation.

Discuss changes that occur in cells as a person ages.
