BIOL 251 ANATOMY AND PHYSIOLOGY EXAM 1 : TISSUES
COMPLETE EXAM REVIEW | VERIFIED & UPDATED 2025–2026
tissues - correct 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 - correct answer -pros: cell specialization allows body to carry out
complicated functions
cons: destruction of one cell type can be catastrophic
4 primary tissue types - correct answer -nervous, muscle, epithelial, connective
nervous tissue - correct answer -regulates and controls body functions, composed of brain,
spinal cord, nerves
nervous tissue type: neurons - correct answer -capable of transmitting electrical impulses
through entire body, can respond to various stimuli
nervous tissue type : supporting cells - correct answer -nonconducting cells
function is to protect, insulate, support neurons
muscle tissue - correct answer -innervated, well vascularized.
actin and myosin - correct answer -found in muscle tissue, microfilaments that interact,
allowing muscles to contract/move
3 types of muscle tissue - correct answer -skeletal, cardiac, smooth
, skeletal muscle - correct answer -
cardiac muscle - correct answer -
cardiac muscle - correct answer -involuntary, striated, found only in walls of heart
epithelial - correct answer -
Epithelial tissue : covering epithelium - correct answer -outer layer of skin, urogenital, digestive,
and respiratory systems.
- covers walls/organs of closed body cavity
epithelial tissue : glandular epithelium - correct answer -makes up the glands of the body
characteristics of epithelial tissue - correct answer -apical basal polarity : apical surface "expose
side" and basal surface "attaches to connective tissue"
apical surface of epithelial tissue - correct answer -
basal surface - correct answer -attaches to connective tissue
- has attached basal lamina (filters what can/cant enter epithelial layer)
basal lamina - correct answer -filters what can/cant enter epithelial layer
types of junctions between epithelial cells - correct answer -tight junctions and desmosomes
