Classification of body membranes

Peritoneum — lines abdominal cavity and covers organs there Pleura — surrounds the lungs and isolates lungs from the heart in the thorax Pericardium — surrounds the heart Connective tissue — synovial — composed of soft areolar connective tissue and no epithelial cells at all — line the fibrous capsules surrounding joints where they provide a smooth surface and secrete a lubricating fluid and they line small sacs of connective tissue called bursae and the tube-like tendon sheaths to cushion organs moving against each other during muscle activity.

Serous membranes have special names given according to their location.

cutaneous membrane

It is a stratified squamous epithelial membrane resting on top of connective tissue. Connective Tissue Membranes Connective tissue membranes contain only connective tissue. Synovial Membranes Synovial membranes are connective tissue membranes that line the cavities of the freely movable joints such as the shoulder, elbow, and knee.

Meninges The connective tissue covering on the brain and spinal cordwithin the dorsal cavityare called meninges.

body membranes function

This synovial fluid readily exchanges water and nutrients with blood, as do all body fluids. Epithelial membranes — include the cutaneous membrane skinthe mucous and serous membranes — they all contain an epithelial sheet and are combined with an underlying layer of connective tissue — these membranes are actually simple organs Cutaneous — Outermost protective boundary, skin that is waterproof, stretchable, washable — exposed to air and is a dry membrane — superficial epidermis is composed of keratinizing stratified squamous epithelium and underlying dermis is mostly dense fibrous connective tissue.

They provide protection for these vital structures.

Classification of body membranes chapter 4 answers

Mucous, produced by the epithelial exocrine glands, covers the epithelial layer. Serous fluid lubricates the membrane and reduces friction and abrasion when organs in the thoracic or abdominopelvic cavity move against each other or the cavity wall. Other examples include the respiratory , excretory, and reproductive tracts. Serous membranes are covered by a thin layer of serous fluid that is secreted by the epithelium. This synovial fluid readily exchanges water and nutrients with blood, as do all body fluids. These membranes line cavities that do not open to the outside, and they cover the organs located within those cavities. They can be categorized into epithelial and connective tissue membrane. Connective Tissue Membranes Connective tissue membranes contain only connective tissue. Tissue Membranes The two broad categories of tissue membranes in the body are 1 connective tissue membranes, which include synovial membranes, and 2 epithelial membranes, which include mucous membranes, serous membranes, and the cutaneous membrane, in other words, the skin. Like serous membranes, they line cavities that do not open to the outside. For example, the serous membrane that lines the thoracic cavity and covers the lungs is called pleura. Classification of Body Membranes Classification of Body Membranes List the general functions of each membrane type-cutaneous, mucous, serous, and synovial-and give its location in the body. Fibroblasts in the inner layer of the synovial membrane release hyaluronan into the joint cavity. These membranes, sometimes called mucosae , line the body cavities that open to the outside. Sometimes called mucosae, these epithelial membranes line the body cavities and hollow passageways that open to the external environment, and include the digestive, respiratory, excretory, and reproductive tracts.

Sometimes called mucosae, these epithelial membranes line the body cavities and hollow passageways that open to the external environment, and include the digestive, respiratory, excretory, and reproductive tracts.

These membranes encapsulate organs, such as the kidneys, and line our movable joints. Synovial membranes secrete synovial fluid into the joint cavity, and this lubricates the cartilage on the ends of the bones so that they can move freely and without friction. They can be categorized into epithelial and connective tissue membrane.

Epithelial membranes

Epithelial membranes — include the cutaneous membrane skin , the mucous and serous membranes — they all contain an epithelial sheet and are combined with an underlying layer of connective tissue — these membranes are actually simple organs Cutaneous — Outermost protective boundary, skin that is waterproof, stretchable, washable — exposed to air and is a dry membrane — superficial epidermis is composed of keratinizing stratified squamous epithelium and underlying dermis is mostly dense fibrous connective tissue. Synovial membranes and meninges belong to this category. Synovial Membranes Synovial membranes are connective tissue membranes that line the cavities of the freely movable joints such as the shoulder, elbow, and knee. Fibroblasts in the inner layer of the synovial membrane release hyaluronan into the joint cavity. Like serous membranes, they line cavities that do not open to the outside.

Synovial membranes secrete synovial fluid into the joint cavity, and this lubricates the cartilage on the ends of the bones so that they can move freely and without friction. Serous fluid secreted by the cells lubricates the membrane and reduces abrasion and friction between the two layers.
