List the Serous membranes
Parietal peritoneum, visceral peritoneum, parietal pericardium, visceral pericardium, parietal pleura, visceral pleura
What do serous membranes consist of?
simple squamous epithelium, thin layer of loose connective tissue
What are some mucous membranes?
mucosa of nasal cavity, mucosa of mouth, esophagus lining, mucosa of lung bronchi
Mucous Membrane
The epithelial membrane that lines body cavities open to the exterior
Endothelium
Lines blood vessels and the heart.
Makes up the pleura and pericardium.
Serous Membrane
Serous Membrane
Found lining the digestive and
respiratory tracts --> Mucous Membrane
The epithelial membrane that lines the closed ventral cavities of the body
Mucous (epithelial membrane)
lines body cavities open to the exterior (e.g. digestive and respiratory tracts)
- is a water-soluble, complex glycoprotein that is secreted by goblet cells.
- Like mucous cells, goblet cells are unicellular exocrine glands that secrete mucin, a protein that combines with water to form mucus. In goblet cells, the cuplike accumulation of mucin distends the top of the cell, making these cells look like a glass with a stem, thus "goblet" cell. This distortion does not occur in mucous cells.
Cutaneous Membrane
Consists of keratinized stratified squamous epithelium
- Which tissue is correctly paired with its primary cell type?
- Osteoblasts/cytes are the primary cell type for bone.
- use ducts to secrete substances into the external environment (onto the surfaces of the cutaneous and mucous membranes). Note: "exo" means outside. Endocrine glands are ductless; they secrete hormones into the extracellular fluid of our internal environment. Note: "endo" means inside.
- Exocrine glands
- The shape of the external ear is maintained by ________.
- elastic cartilage
What tissue has lacunae, calcium salts, and blood vessels?
osseous tissue
- Why are adipose, blood, and bone all considered to be connective tissues?
- They have a common origin, mesenchyme Adipose, bone, and blood (like all connective tissues) are derived from mesenchyme, an embryonic tissue. Also common to all connective tissues is the presence of cells and an extracellular matrix that consists of fibers bathed in ground substance.
- What are the three main components of connective tissue?
- ground substance, fibers, and cells
- Aunt Jessie woke up one morning with excruciating pain in her chest. She had trouble breathing for several weeks. Following a visit to the doctor, she was told she had pleurisy. What is this condition and what did it affect?
- Pleurisy is an inflammation of the pleura, the serosal membranes covering the lungs and lining the thoracic wall. Pain is caused by the irritation and friction as the lungs rub against the walls of the cavity.
- Aunt Jessie woke up one morning with excruciating pain in her chest. She had trouble breathing for several weeks. Following a visit to the doctor, she was told she had pleurisy. What is this condition and what did it affect?
- Pleurisy is inflammation of the serous membranes covering the lungs. Inflamed pleural serous membranes create friction, resulting in pain as the lungs move during breathing.
An infection may occur in a tissue injury. Why?
- The increased availability of nutrients allows microorganisms to replicate. The skin and mucous membranes are body's first line of defense and are mostly impenetrable to microorganisms, unless broken or damaged by tissue injury.
- Which of the following is a single-celled layer of epithelium that forms the lining of serous membranes?
- simple squamous
- A many-layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as
- stratified squamous
- epithelium appears to have two or three layers of cells, but all the cells are in contact with the basement membrane.
- Pseudostratified columnar
- Select the correct statement regarding tissue repair.
Granulation tissue is highly susceptible to infection.
Inflammation causes
capillaries to dilate and become permeable.
Granulation tissue is another
name for a blood clot.
The clot is formed from dried blood and transposed collagen fibers.
- Pseudostratified columnar epithelium ciliated variety
- lines most of the respiratory tract
