What are the 4 membrane types?
The four types of membranes are: 1) cutaneous membranes; 2) serous membranes; 3) mucous membranes; and 4) synovial membranes. The cutaneous membrane is skin. Skin consists of a layer of stratified squamous epithelium (epidermis) firmly attached to a thick layer of dense connective tissue (dermis).
Where is skin the thickest?
Skin is thickest on the palms and soles of the feet (1.5 mm thick), while the thinnest skin is found on the eyelids and in the postauricular region (0.05 mm thick). Male skin is characteristically thicker than female skin in all anatomic locations.
What are the three types of membranes?
There are three types of epithelial membranes: mucous, which contain glands; serous, which secrete fluid; and cutaneous which makes up the skin.

What membrane makes up the largest organ in the body?
Skin is the largest organ in the body and covers the body’s entire external surface. It is made up of three layers, the epidermis, dermis, and the hypodermis, all three of which vary significantly in their anatomy and function.
What membrane covers the outside of the heart?
The Pericardium. The pericardium is the fibrous sac that surrounds the heart. It can be divided into three layers, the fibrous pericardium, the parietal pericardium, and the visceral pericardium. The parietal and visceral pericardia together form the serous pericardium.

What is the thickest layer of skin?
The squamous cell layer is the thickest layer of the epidermis, and is involved in the transfer of certain substances in and out of the body. The squamous cell layer also contains cells called Langerhans cells.
What type of epithelial membrane covers the outside surface of the body?
skin– the epithelial membrane that covers the body surface.
How can the skin be both a membrane and an organ?
The integumentary system (skin) has been called a membrane and an organ but, it is generally considered a system because it has organs that work together as a system. It is sometimes considered an organ because it contains several types of tissues and a membrane and it covers the body.

Which is the hardest connective tissue?
Bone is the hardest connective tissue. It provides protection to internal organs and supports the body. Bone’s rigid extracellular matrix contains mostly collagen fibers embedded in a mineralized ground substance containing hydroxyapatite, a form of calcium phosphate.
Why skin is an organ not a tissue?
The skin is an organ because it is made up of different tissues that work together to perform the functions of the skin. A tissue is made up of cells generally. However it is more appropriate to describe the skin as an organ as the cells have been organised into different tissues that make up an organ.

What are the 6 serous membranes?
Name the six serous membrane layers the blade passes through as it moves from the body surface into the heart. Parietal pleura, visceral pleura, (lung), visceral pleura, parietal pleura, parietal pericardium, visceral pericardium, (heart).
Is skin a tissue or organ?
The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature.
Which serous membrane is closest to the surface of the heart?
There are three serous cavities and their associated membranes. The pleura is the serous membrane that encloses the pleural cavity; the pleural cavity surrounds the lungs. The pericardium is the serous membrane that encloses the pericardial cavity; the pericardial cavity surrounds the heart.
What membrane covers the surface of the heart quizlet?
Visceral pericardium/ Epicardium– serous membrane that covers the surface of the heart and secretes serous fluid to lubricate the heart.
Are Narcissists thin skinned?
