Membranes = Thin Sheets of Cells/Simple Organs

Thin sheets of flexible tissue that line or cover parts of the
body are called membranes.

Epithelial membranes contain an epithelium and an
underlying connective tissue:




mucous membranes
serous membranes
cutaneous membrane
Synovial membranes contain only connective tissues, and
line the cavities of synovial joints

Mucous Membranes (or Mucosa)

Mucous membranes line body cavities open to the outside

mucosa are important in preventing infection of the body

The epithelial layer secretes mucus, a thick slippery fluid

The epithelium rests on an areolar tissue layer, the lamina
propria

Serous Membranes


Serous membranes cover the surface of organs that are
not exposed to the outside, and secrete a watery fluid
Serous membranes have two layers:



the parietal layer attaches to the body wall around the
organ
the visceral layer attaches to the organs themselves
Prominent examples: the pleura surround the lungs, the
pericardium surrounds the heart, peritoneum in
abdomen

Cutaneous Membrane and Synovial Membrane

The cutaneous membrane is the skin, covering the outer
surface of the body

Synovial membranes line the cavities of freely movable joints,
and contain only connective tissues

Nervous Tissue
Nervous tissue is highly variable and complex, it
includes two broad groups of cells:

neurons collect, send and receive, and process
information
 neuroglial cells nourish and protect the neurons

Healing of Injured Tissues

Tissue repair is required when cells die due to injury, or when
cells get old and “wear out”

Different tissues vary considerably in their capacity for repair

Replacement of damaged cells depends on:


cell division (of stem cells or migrating cells) to create new cells

differentiation of the new cells to their mature phenotype
Healing of tissues is very dependent on their blood supply,
and on adequate nutrition
