The tissue level of organization - Tissue membranes made from epithelia and connective tissue make up four types of physical barriers

8 important questions on The tissue level of organization - Tissue membranes made from epithelia and connective tissue make up four types of physical barriers

What is a mucous membrane?

Mucous membranes, or mucosae, line passageways and chambers that open to the exterior, including those in the digestive respiratory, urinary, and reproductive tracts.
Many mucous membranes contain simple epithelia that perform absorptive or secretory functions, such as the simple columnar epithelium of the digestive tract.

What is a serous membrane?

Serous membranes line the sealed, internal cavities of the trunk, cavities that are not open to the exterior. These membranes cover the organs.

What are the two categories of serous membranes?

  • Parietal portion; lines the inner surface of the cavity
  • Visceral portion (or serosa); covers the outer surfaces of visceral organs
  • Higher grades + faster learning

What is a cutaneous membrane?

The cutaneous membrane is the skin that covers the surface of your body. It consists of a keratinized stratified squamous epithelium and a layer of areolar tissue reinforced by underlying dense irregular connective tissu.

What is a synovial membrane?

A synovial membrane consists of two layers: areolar tissue and an atypical or unusual epithelium. It is located in between bones, in the joints.

Identify the four types of tissue membranes found in the body.

  • Mucous membrane
  • Serous membrane
  • Cutaneous membrane
  • Synovial membrane

Which cavities in the body are lined by serous membranes?

The pleural, peritoneal, and pericardial cavities are all lined by serous membrane.

Which type of tissue membrane typically lines body passageways (such as the urinary tract) that open to the exterior?

Mucous membrane.
