Which type of membrane contains connective tissue?Group of answer choicesMucous membraneSerous membraneSynovial membraneMucous, serous, and synovial membranes

All three types of membranes - Mucous, Serous, and Synovial membranes - contain connective tissue.

1. Mucous Membranes: These are found in areas that are open to the external environment like the respiratory, digestive, and reproductive tracts. They consist of epithelial cells, an underlying basement membrane, and a lamina propria, which is a layer of loose connective tissue.

2. Serous Membranes: These line body cavities that do not open to the external environment, such as the thoracic cavity and abdominal cavity. They consist of simple squamous epithelium (mesothelium) and a thin layer of loose connective tissue (areolar tissue).

3. Synovial Membranes: These line the cavities of joints, tendon sheaths, and bursae. They consist of a layer of connective tissue and produce synovial fluid for lubrication.
