Tissue Types and Epithelial Functions

Major Types of Tissues in the Body

• Four major types of tissues: epithelial, connective, muscle, and nervous tissue.
• Epithelial tissue covers body surfaces and lines body cavities, providing protection and secretion.

Connective Tissue

• Establishes the framework of the body, providing support and structure to organs and tissues.
• Responsible for supporting and protecting organs, such as bones and cartilage.

Muscle Tissue

• Responsible for contraction and enabling movement of body parts.
• Three types of muscle tissue: skeletal (voluntary movement), cardiac (heart muscle), and smooth (involuntary movement).

Nervous Tissue

• Coordinates body activities by transmitting electrical signals throughout the body.
• Composed of neurons and supporting cells, facilitating communication between different body parts.

Tissue Membranes

• Epithelial tissue combines with connective tissue to form various types of tissue membranes, such as mucous, serous, and synovial membranes.
