Epithelial Membranes
Serous Mucous Cutaneous Synovial
Types of Membranes
Serous Membrane
Mucous Membrane
Cutaneous Membrane
Synovial Membrane
Types of Membranes
Serous Membrane
• Lines cavities not open to outside
• Thoracic cavity & abdominal cavity
• Mesotheilial Cells
• Specialized simple squamous epithelium
• Secretes serous fluid (watery)
• Reduces friction between organs
Figure 1.11 Serous membranes of the heart and lungs
Serous Pericardium = serous membrane surrounding the heart
Pleura = serous membrane surrounding the lungs
Figure 1.12 Serous membranes of the abdomen
Peritoneum – Serous membrane that surround several
abdominal organs
Serous Membrane
Mucous Membrane
• Lines cavities & tubes open to outside
Types of Membranes
Serous Membrane• Lines cavities & tubes open to outside
• Nasal & oral cavity
• Digestive, respiratory, and reproductive tracts
• Goblet Cells – Secrete Mucus
Cutaneous Membrane
• Skin
Types of MembranesTypes of Membranes
• Skin
• Protective covering
Mucous Membrane
Synovial Membrane
• Composed entirely of connective tissue
Types of MembranesTypes of Membranes
Mucous Membrane• Composed entirely of connective tissue
• Lines joints
• Secretes synovial fluid = clear viscous fluid
Muscle Tissues
Muscle Tissue
• Designed to contract
Muscle Tissues
Skeletal Muscle Smooth Muscle Cardiac Muscle
Skeletal Muscle
• Moves Skeleton = voluntary
• Characteristics
• Long tubular cells
• Several peripheral nuclei
• Striated
Smooth Muscle
• Involuntary
• Within walls of viscera
• Stomach, intestines, uterus, blood vessels, ect.
• Tapered cells, form broad sheets
• Single central nucleus
Cardiac Muscle
• Located only within wall of the heart
• Involuntary control
• Striated
• Branched cells with central nuclei
• Intercalated discs
Nervous Tissue
• Locations = brain, spinal cord, and peripheral nerves
• Regulates, coordinates, and integrates body activities
• Cells = Neurons & Neuroglia
• Neurons transmit impulses
• Neuroglia support neurons
