Tissues Flashcards
Do epithelial tissue contain blood vessels?
No, avascular
What does endothelium and mesothelium cover in simple squamous epithelial tissue
Endothelium: Inner covering for cardiovascular system; capillaries has this tissue for exchange of nutrients
Mesothelium: middle covering for pleura, peritoneum, pericardium
Where are the non-ciliated simple columnar epithelial tissues located? and the ciliated?
Non-ciliated: lines most of the digestive tract
- has dense microvilli to increase SA
Ciliated: Lines bronchi
What are goblet cells
secrete a protective lubricating mucus in digestive tract
- unicellular exocrine gland
Where are nonkeratinized stratified squamous found? keratinized?
- in moist linings
- in a dry membrane (skin)
- cutaneous membrane
Where are the non-ciliated PSEUDOSTRATIFIED columnar epithelial tissues located? and the ciliated?
nonciliated: sperm-carrying ducts
ciliated: lines the trachea and most of upper respiratory tract
Where do the nuclei of pseudostratified columnar sit
basement membrane
Which tissue typically has 2 cell layers
stratified cuboidal
What is a key feature of stratified columnar
only its apical layer is columnar
What line up body cavities open to exterior (mouth, nasal, urinary tract)
mucous membrane
What type of membranes are around parietal & visceral peritoneum (hand in balloon)
serous fluid
Where does the endocrine gland secrete onto? exocrine?
Endocrine: ductless gland secrete into blood stream
Exocrine: secrete onto body surfaces or body cavities
What ducts contain:
1. Compound tubular
2. Compound alveolar
- Brunners glands ducts
- Milk ducts
How is merocrine and holocrine secreted
merocrine: exocytosis (ex. pancreas, sweat, saliva)
Holocrine: cell is ruptured, structure lost; (ex. oil (sebaceous) glands of skin)
What type of tissue is the most abundant
connective tissue
What does areolar loose connective tissue do?
Reservoir of water and salts
wraps around cushions
What do adipose loose connective tissue have?
a lot of mitochondria to heat blood
what tissue forms a fascia (fibrous membrane that wraps around muscles, BV, nerves)
dense regular connective tissue
What tissue forms a fibrous joint capsules?
dense irregular connective tissue
What type of cartilage is articular cartilage that covers the ends of long bones?
hyaline cartilage
- connects ribs to sternum, support most of respiratory system
Where is fibrocartilage cartilage found
intervertebral discs, pubic symphasis, and spongy cartilages of knee
- where strong support is needed
which connective tissue develops from mesenchyme
connective tissue proper, cartilage, bone, blood
What type of nucleii in skeletal? and cardiac tissue? and smooth?
Skeletal: multinucleate
Cardiac: uninucleaete
Smooth: uni
What is the difference between inflammatory response and immune response in tissue trama?
Inflammatory: nonspecific, develops quick
Immune: very specific, develops slow
