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

17

What are some examples of Thermoregulatory behaviors in hot weather?

Grazing cattle, sheep and horses seek out shade
Pigs look for mud holes
Increase fluid intake
