Biol 251 Anatomy and Physiology:
Tissues Test Questions and Correct
Answers.
tissues - Answer any grouping of cells that are similar in structure and carry out a similar or
common function in the body
pros and cons of tissues - Answer pros: cell specialization allows body to carry out
complicated functions
cons: destruction of one cell type can be catastrophic
4 primary tissue types - Answer nervous, muscle, epithelial, connective
nervous tissue - Answer regulates and controls body functions, composed of brain, spinal
cord, nerves
nervous tissue type: neurons - Answer capable of transmitting electrical impulses through
entire body, can respond to various stimuli
nervous tissue type : supporting cells - Answer nonconducting cells
function is to protect, insulate, support neurons
muscle tissue - Answer innervated, well vascularized.
actin and myosin - Answer found in muscle tissue, microfilaments that interact, allowing
muscles to contract/move
3 types of muscle tissue - Answer skeletal, cardiac, smooth
skeletal muscle - Answer
cardiac muscle - Answer
cardiac muscle - Answer involuntary, striated, found only in walls of heart
epithelial - Answer
, Epithelial tissue : covering epithelium - Answer outer layer of skin, urogenital, digestive, and
respiratory systems.
- covers walls/organs of closed body cavity
epithelial tissue : glandular epithelium - Answer makes up the glands of the body
characteristics of epithelial tissue - Answer apical basal polarity : apical surface "expose side"
and basal surface "attaches to connective tissue"
apical surface of epithelial tissue - Answer
basal surface - Answer attaches to connective tissue
- has attached basal lamina (filters what can/cant enter epithelial layer)
basal lamina - Answer filters what can/cant enter epithelial layer
types of junctions between epithelial cells - Answer tight junctions and desmosomes
basement membrane in epithelial tissue (support) - Answer lies between epithelial layer and
connective tissue
function: reinforces epithelial sheet to resist stretching/tearing/ defines epithelial boundary
basement membrane layers - Answer basal lamina and reticular lamina (contains fibers
belonging to connective tissues)
avascular - Answer has no blood supply, receives nourishment through diffusion
innervated - Answer supplied with nerve fibers
Regeneration - Answer high capacity for regeneration
epithelial tissue characteristics - Answer avascular, innervated, regeneration capability
classification of epithelial cells based on - Answer thickness (number of cells present in
epithilia), shape
