Figure 7.1 Lateral View of the Human Skull CHAPTER OBJECTIVES After studying this chapter, you will be able to: The skeletal system forms the rigid internal framework of the body. It consists of the bones, cartilages, and ligaments. Bones support the weight…
Learning Objectives By the end of this section, you will be able to: Tissues of all types are vulnerable to injury and, inevitably, aging. In the former case, understanding how tissues respond to damage can guide strategies to aid repair.…
Learning Objectives By the end of this section, you will be able to: Nervous tissue is characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body with information. Two main classes of cells make…
Learning Objectives By the end of this section, you will be able to: Muscle tissue is characterized by properties that allow movement. Muscle cells are excitable; they respond to a stimulus. They are contractile, meaning they can shorten and generate…
Learning Objectives By the end of this section, you will be able to: As may be obvious from its name, one of the major functions of connective tissue is to connect tissues and organs. Unlike epithelial tissue, which is composed…
Learning Objectives By the end of this section, you will be able to: Most epithelial tissues are essentially large sheets of cells covering all the surfaces of the body exposed to the outside world and lining the outside of organs.…
Learning Objectives By the end of this section, you will be able to: The term tissue is used to describe a group of cells found together in the body. The cells within a tissue share a common embryonic origin. Microscopic observation reveals…
CHAPTER OBJECTIVES After studying this chapter, you will be able to: The body contains at least 200 distinct cell types. These cells contain essentially the same internal structures yet they vary enormously in shape and function. The different types of…
Learning Objectives By the end of this section, you will be able to: Calcium is not only the most abundant mineral in bone, it is also the most abundant mineral in the human body. Calcium ions are needed not only…
Learning Objectives By the end of this section, you will be able to: All of the organ systems of your body are interdependent, and the skeletal system is no exception. The food you take in via your digestive system and…
