Biology Questions and Answers
- Of which cells is the
nervous tissue constituted?
How is the generic function of
this tissue related to the
characteristics of the main cell
type that forms it?
The nervous tissue is formed of neurons
and glial cells.
The function of the nervous tissue is to
receive (reception anand to transmitd transmission of neural imp ulses
information). characteristic morphology oThis function jf neurons,ustifies the
with membrane projections (dendrites)
to get information membrane projection (axoand an elongatedn, or nerve (^)
fiber) to transmit information at
distance.support the neurons and facilitate In their turn, the glial cells their (^)
work (sometimes acting as insulators).
- What are muscle tissues?
How is the function of this
tissue related to the typical
characteristics of its cells?
Muscle tissuesable to perform contractions are tissues made of cells and thus to (^)
generate movement.
The function of the muscle tissue is to
pull bones (skeletal striated mcontract and move viscera and vesselsuscle), to
(smooth muscle) and to make the heart
to beat (carmuscle cells have internal diac striated muscle). Tstructureshe
called sarcomeres where there are
myosin create contraction anand actin moleculd distensiones disposed to
(movement).
- What is the typical
biological function of the
connective tissues? How is
this function associated to the
main features of its cells?
The typicaltissues is to fill e function mpty spaces amof the connectiveong
other body tissues.
This function is relatecapability of the cells of the connectived to the great (^)
tissue to constitutesecrete s extracellularubstances that material, like (^)
collagen and elastic fibers, creating a
significant spacing between these cells.
(There are other important biological
features of the connective tissues,as substance transportation, defense of such (^)
the organism, etc.)
- Of which type of tissue are
cartilages and bones made?
Bones and cartilages, tissuesamount of intercellular material, ar with greate
formed of connective tissue. - Are the cells of the
connective tissue far or near
to the others?
The relative gis a typical feature of the connectivereat spacing between cells
tissue. Tmaterial ghere are much inteenerally secreted by thercellular
tissue cells.
