Use the key to classify each of the following described tissue types into one of the four major tissue categories. Key: connective tissue epithelium muscle nervous tissue  _________    (1) Tissue type composed largely of nonliving extracellular matrix; important in protection and support  _________    (2) The tissue immediately responsible for body movement  _________    (3) The tissue that enables us to be aware of the external environment and to react to it  _________    (4) The tissue that lines body cavities and covers surfaces

Verified step by step guidance

1. Identify the tissue type that is composed largely of nonliving extracellular matrix, which is important in protection and support. This is characteristic of connective tissue.
2. Determine the tissue type that is immediately responsible for body movement. This is a function of muscle tissue.
3. Recognize the tissue type that enables awareness of the external environment and reaction to it. This is a function of nervous tissue.
4. Identify the tissue type that lines body cavities and covers surfaces. This is characteristic of epithelium.
5. Use the key provided to classify each tissue type based on the descriptions given.

Key Concepts

Connective Tissue

Connective tissue is characterized by its composition of a large amount of extracellular matrix, which provides structural support and protection to organs and tissues. It includes various types such as bone, blood, and adipose tissue, each serving distinct functions in the body. The matrix can vary in consistency, influencing the tissue's properties and roles.

Muscle Tissue

Muscle tissue is specialized for contraction and is responsible for body movement. There are three types: skeletal muscle, which moves bones; cardiac muscle, which makes up the heart; and smooth muscle, found in walls of hollow organs. Each type has unique structural features that enable its specific functions in movement and control.

Nervous Tissue

Nervous tissue is essential for communication within the body, consisting of neurons and glial cells. Neurons transmit electrical signals, allowing for rapid responses to stimuli, while glial cells support and protect neurons. This tissue is crucial for processing sensory information and coordinating bodily responses to the environment.
