COMPREHENSIVE REVIEW
What is positive feedback system? - answer strengthens or reinforces a change in one
of the body's controlled conditions. (childbirth, breastfeeding, clotting)
What is negative feedback? - answer A response to a change in the body that
counteracts or opposes the initial change.
What is an example of negative feedback? - answer Temperature, Blood glucose levels,
Blood volume/ pH/ composition
What is an example of positive feedback? - Answer-Blood clotting. The initial clotting
triggers the formation of more clots.
- child birth
What is avascular? - answerlack of blood vessels
No blood supply
What is vascular ? - answerblood vessels (pulmonary division and systemic system)
epithelial tissue - answerA body tissue that covers the surfaces of the body, inside and
out
What are the four types of tissues? - answerepithelial, connective, muscular, nervous
Muscular tissue is - answerContracts and moves the various parts of the body.
- involuntary
Muscular tissue is - answercontractile
Connective tissue is - answerA body tissue that provides support for the body and
connects all of its parts
Nervous tissue is - answerhighly cellular
An example of nervous tissue - answerbrain
An example of epithelial tissue - answerskin (epidermis)
An example of a connective tissue is the - answerblood
, What are the three muscular tissues? - answerskeletal, cardiac, smooth
What is skeletal muscle? - answerlong, thin, cylindrical in shape, multinucleated,
attached to bone and skin, voluntary movement, striated
What is cardiac muscle? - answershort, fat, branched, uninucleated, found in the heart,
attached to intercalated discs, involuntary, striated
What is smooth muscle? - answerfound in hollow organs, uninucleated, involuntary, lack
striations
What are the functions of muscles? - answerExcitability, conductivity, extensibility,
elasticity, contractility
What is excitability? - answerability to receive and respond to stimuli
What is conductivity? - answerThe ability of an object to transfer heat or electricity to
another object.
What is extensibility? - answerthe ability to be stretched or extended
What is elasticity? - answerability of muscle to recoil to original resting length after
stretched
What is contractility? - answerNormal ability of muscle to contract at a given force for a
given stretch. It is independent of preload/afterload
What is polar? - answerunequal sharing of electrons
Why are epithelial cells polarized? - answerpolarization allows epithelial cells to
transport molecules across the surface in a directional manner
Three protein fibers of connective tissue - answerCollagen, reticular and elastic fiber
What is a collagen fiber? - answerStrong fiber that gives tissues high tensile strength
What is reticular fiber? - answerFibers that branch to form a supporting network
What is elastic fiber? - answerNetworks of long, thin, elastin fibers that allow for stretch
What is chondroitin sulfate? - answerprovides support and adhesiveness in cartilage,
bone, skin, and blood vessels
Where is chondroitin sulfate located in the body? - answerCartilage, bone , skin,
ligaments and tendons
