1
What are the 4 basic tissue types in all animals?
1. Epithelial
2. Neural
3. Muscular
4. Connective
2
Name some properties of Epithelial Tissue.
Line ALL body cavities, organ surfaces and blood vessels
Partly Avascular therefore dependent upon diffusion for nutrients
3
Name some properties of Neural Tissue.
Excitability
Conductivity
Resistance to Fatigue
"All or None"
4
Name some properties of Muscle tissue
Contractility
Extensibility
Elasticity
Excitability
Highly vascularized
5
Name some properties of Connective tissue
Vascular and Avascular
More extracellular matrix than cells
Can Replicate
6
Name the 3 important cell to cell junctions
1. Desmosomes
2. Tight (adherens) junctions
3. Gap junctions
7
_____ Anchor cells together
Desmosomes
8
_____ Block movement of molecules between cells
Tight junctions
9
_____ Allow communication between cells
Gap junctions
10
_____ is maintenance of a relatively constant condition in the internal environment.
Homeostasis
11
_____ is dynamic state of homeostasis with capacity to shift the parameters of homeostasis during specific states such as growth, severe immune challenge, pregnancy, lactation, aging.
Homeorrhesis
12
_____ can be subdivided into two categories: Anabolism and Catabolism
Metabolism
13
_____ uptake and storage of substrates by tissue for growth, adding to reserves (protein synthesis, lipid synthesis, glycogen synthesis)
Anabolism
14
_____ utilization and mobilization of nutritional substrates through breakdown of complex compounds to smaller more simple compounds.
Catabolism
15
_____ is the ambient temp range when circulatory adjustments are sufficient to maintain a steady homeothermic state
Thermoneutral zone
16
What is the thermoneutral zone of cattle?
-20 degrees C to +20 degrees C
