Chapter 4 Flashcards
What is an example of simple cuboidal tissue?
Kidney tubules, ovary surface.
What are some examples of simple squamous tissue?
Air sacs, lining of heart, blood vessels, lymphatic vessels, and the lining of the central cavity.
What is an example of simple columnar tissue?
Galbladder, small intenstine.
What is an example of pseudo-stratified columnar tissue?
Trachea, upper respiratory tract
What is an example of stratified squamous epithelium?
Mouth and vag.
What is an example of transitional epithelium?
Bladder; changes shape on a regular basis, stretches.
Name the primary tissues and their function
Connective: supports
Epithelial: covers
Muscle: movement
Nerve: controls
Name the locations of these different types of muscle:
Smooth
Cardiac
Skeletal
Smooth: hollow organs
Cardiac: heart
Skeletal: bones
Name the functions of epithelial tissue.
Protects Absorbs Filtration Excretion Secretion Sensory reception
What is the difference between simple and stratified tissue?
Simple is single layered, while stratified is two or more layers.
Name the differences between these tissue types:
Squamous
Cuboidal
Columnar
Squamous: flat (nucleus flat)
Cuboidal: cube (hexagon shape)
Columnar: column (nucleus elongated)
Name 4 duct-less glands.
Glucose
Insulin
Epinephrine
Adrenaline
What is a multi-cellular exocrine gland composed of?
A duct and a secretory unit.
Types of unicellular exocrine glands:
Goblet cells
Mucous cells
3 different types multicellular glands:
- Merocrine (most): excrete by exocytosis
- Holocrine: accumulates products within and ruptures
- Apocrine: accumulates products within and ruptures at apex.
3 types of connective tissue fiber
- Collagen: strongest, most abundant.
- Elastic: Networks of long, thin elastic fibers that allow for stretch and recoil.
- Reticular: short, fine, highly branched collagenous fibers.
What is the purpose of osteoblasts?
To create bone
What is the purpose of osteoclasts?
To destroy bone.
Function of fat cells.
Store nutrients
Function of white blood cells.
Tissue response to injury
Function of mast cells.
Initiate local response to inflammatory response.
Function of macrophages.
Cells that eat dead cells.
3 steps in regeneration of tissue.
1) inflammation
2) clotting
3) organization restores blood supply; repairs damage
What are tissues?
Individual body cells that perform common or related functions.
