Body Membranes

What are the functions of body membranes

cover body surfaces, line body cavities, form protective sheets around organs

What are epithelial membranes?

cutaneous, mucous, serous

What are the connective tissue membranes

synovial membranes

cutaneous membrane

Skin

-dry membrane, outermost protective boundary

Type of cells in epidermis

stratified squamous

Type of cells in dermis

Dense fibrous connective tissue

T/f sweat glands go straight to the pore

True

mucous membrane

-moist membrane

-lines all body cavities that open to the exterior body surface (gi, reproductive, and urinary)

-absorption and secretion

What type of connective tissue is found in the mucous membrane

Loose connective in the lamia propria

How many layers of the skin

2, epidermis and dermis

serous membrane

Lines all body cavities that are closed to the exterior

-visceral and parietal layer

Difference between the visceral and parietal layer

Visceral: direct contact with the organ

Parietal: cavity contact

What's in between the visceral and parietal layer

Fluid

Type of tissue in the serous membrane

Simple squamous and areolar connective tissue

What is the purpose for the parietal and visceral layer

Protects against friction, heat, and death of cells

peritoneum serous membrane

Abdominal cavity

pleura serous membrane

Around the lungs

pericardium serous membrane

Around the heart

synovial membrane

lines fibrous capsules surrounding joints

-Bursae

-tendon sheath

• secrete a foiled to cushion organs moving against eachother during muscle activity

Type of tissue in the synovial membrane

Loose areolar connective tissue
