Which epithelial membranes line the body cavities and cover organs that lie in them, that are not open to the exterior of the body?

A. Mucous: Mucous membranes line cavities that open to the exterior, such as the respiratory, digestive, and urinary tracts.

B. Serous: Serous membranes line body cavities (such as the peritoneum, pleura, and pericardium) that do not open to the outside and produce serous fluid to reduce friction between organs.

C. Cutaneous: The cutaneous membrane is the skin, which covers the external body surface.

D. Synovial: Synovial membranes line joint cavities and secrete synovial fluid to lubricate the joints.

A. Types of muscle tissue: skeletal, cardiac, adipose: This group is incorrect because adipose (fat) is not a type of muscle tissue. The three correct types of muscle tissue are skeletal, cardiac, and smooth.

B. Types of tissue: epithelial, connective, nerve, muscle: The four main types of tissues in the human body are epithelial, connective, nervous, and muscle tissue.

C. Types of nervous cells: neurons, neuroglia. The nervous system consists of neurons (which transmit electrical signals) and neuroglia (which support and protect neurons).

D. Serous membranes: pleura, peritoneum, pericardium. The pleura (lungs), peritoneum (abdominal organs), and pericardium (heart) are all serous membranes.
