(on eye) shield the eyes, and
(on the nose) hairs filter particles from entering the lungs.
Ossification Right Ans - The process of new bone development.
Appendicular Right Ans - The skeletal system associated with shoulders,
arms, and legs.
MInerals Right Ans - Stored in bones (where red blood cells are located)
Skeletal Muscles Right Ans - Use bones as levers to move the different parts
of the body.
Bones Right Ans - Provide a hard framework that supports the body and
cradles the soft organs.
Organs Right Ans - Protected by bones (i.e rib cage)
Axial (Skeletal System) Right Ans - Includes the bones from the head to the
base of the spine.
Fascicules Right Ans - Bundles of muscle fibers grouped together.
Myofibrils Right Ans - A protein strand made up of contractile proteins.
Sarcomeres Right Ans - The basic unit of the myofibril, which contains
myosin and actin.
,Myosin Right Ans - (thick, dark protein) that contributes in the making of a
sarcomere. myofilaments
Actin Right Ans - (thin, light protein) that contributes in the making of a
sarcomere. myofilaments
Cross Bridges Right Ans - Projections extending from the myosin to the
actin
Visceral muscle tissue Right Ans - Smooth muscles found in the organs. An
involuntary type of tissue because we do not consciously contract our organ
or digestive system functioning.
Cardiac muscle tissue Right Ans - Type of tissue found in the heart. It is
responsible for pumping blood through the body. This pumping is, of course,
done through involuntarily contracting.

Electrochemical messengers
Sensory neurons Right Ans - Carry impulses from the periphery nervous
system (arms and legs) to the central nervous system (brain and spinal cord)
Motor Unit Right Ans - Carries impulses from the CNS to the PNS, which
includes one motor neuron and the muscle cells that it stimulates.
Pathway Right Ans - Created between the brain and muscles. You can liken
it to a road under construction...
Artery Right Ans - A blood vessel that carries oxygenated blood from the
heart to any part of the body.
Vein Right Ans - A blood vessel that conveys blood from various parts of
