EXAMINATION TEST 2026 FULL QUESTIONS
AND CORRECT ANSWERS
◉Muscles can only pull on bones. Pushing actions can occur only
because of
the interactions of different ---- pulling on bones. Answer: muscles
◉The ---- of muscle contraction is basically when actin
and myosin slide over each other as the muscle contracts, shortening
the
sarcomere. In order for this to happen, there is a bridge formed
called a
---- from myosin to actin and when this bridge forms, it allows the
actin to be pulled toward the myosin. This "cross bridge cycling"
occurs
over and over to continue the muscle contraction. Answer: "sliding
filament theory"; cross bridge
◉Can we run out of ATP? Answer: No; unless we die
, ◉Concentric is the Answer: shortening of muscle-contraction phase
(positive)
◉What are muscles stimulated by? Answer: Nerves
◉What does a motor unit refer to? What happens when it is
stimulated? Answer: a motor neuron(a brain cell or nerve) and all
the muscle cells that it directly stimulates; all of its associated
muscle fibers contract
◉Eccentric is the Answer: lengthening of muscle during contraction
(negative)
◉The heart is a ---- that is responsible for pushing blood through the
CV
(cardiovascular) system. Answer: pump
◉What is the source of oxygen and nutrients? Answer: Blood
◉Normal BP guidelines Answer: <120/80
◉Prehypertension BP guidelines Answer: 120/80-139/89
