BIO 210 - FINAL EXAM REVIEW
QUESTIONS AND ANSWERS; 100%
PASS GUARANTEED; GRADED A+
2 divisions of the ANS - correct answer- Somatic - Skeletal
Muscle
ANS - smooth muscle, cardiac muscle, and glands
2 regions of ANS - parasympathetic nervous system and
sympathetic nervous system
2 layers of periosteum - correct answer- Fibrous Layer -
Outer layer dense irregular CT
Osteogenic Layer - Inner layer containing osteoblasts (which
secrete bone matrix, Osteoclast (bone destroying cells) and
Osteogenic stem cells (give rise to osteoblasts)
2 types of covalent bonds - correct answer- Polar - unequal
sharing of electrons
Nonpolar - equal sharing of electrons
3 regions of the skin - correct answer- epidermis (outermost)
dermis (vascular layer)
,hypodermis - subcutaneous
3 stages of interphase - correct answer- G1 - Growth and
metabolism
S - DNA replication
G2 - Preparation for division
3 types of muscle tissue - correct answer- skeletal
cardiac
smooth
4 elements that make up 96% of the human body - correct
answer- Oxygen, hydrogen, carbon and nitrogen
5 cell layers of the epidermis - correct answer- stratum
corneum - keratinized - waterproof sloughs off cells are dead
stratum lucidum - only in thick skin - soles of feet and palms of
hands - cells are dead here
stratum granulosum - keratinization begins here
stratum spinosum - tension resisting bundles of pre-keratin
filaments
, stratum basale - actively mitotic stem cells
A band - correct answer- shortens when the muscle
contracts
abdominopelvic cavity - correct answer- stoach digestive
organs
abduction - correct answer- limb moves toward the midline
of the body
Acetylcholine (ACh) - correct answer- neurotransmitter
released at the neuromuscular junction, depolarizes the muscle
cell
actin - correct answer- thin filaments, I band, light colored
Action Potential - correct answer- Graded potential is below
threshold
When NA+ enters cell - depolarization occurs
When K+ exits teh cell repolarization occurs
K+ continues to exit the cell and it becomes hyperpolarized
