3.Ca2+ diffuses into the
sarcomere and binds to
troponin (A). The binding
causes tropomyosin (B) to
move and expose binding sites
(C) on actin (D). This allows the
myosin heads (E) to bind onto
actin forming a crossbridge (F).
4.When ADP and P (G) are
released it causes the myosin
head to move and pull actin
(H), called the power stroke.
ATP
5.ATP (I) causes the myosin
heads to release actin (J).

6.ATP releases energy and reverts
to ADP and P (K).
7.Ca2+ is released from troponin
(L), which causes tropomyosin
to cover the binding sites on
actin (M).
8.The muscle contraction will
continue until the nerve impulse
stops and Ca2+ is no longer
released.

Answer Key
A. Amyotrophic Lateral Sclerosis (ALS)
AKA Lou Gehrig’s disease; hereditary
disease in which motor neurons waste and
die leading to muscle weakness and
eventual death.
B. Leiomyomas
Benign muscle growths that most
commonly form in the uterus, intestines, or
esophagus. The large majority are
harmless, painless, and benign.
C. Myasthenia gravis
Autoimmune disorder that causes the body
to produce antibodies that interfere with
muscles cells receiving messages from
motor neurons.
D. Botulism
Clostridium botulinum bacteria produce a
toxin that blocks the release of
neurotransmitters at neuromuscular
junctions. This results in an inability of
muscles to contract.
E. Tetanus
A
B
C
D
E
Colostridium tetani bacteria that enters the
blood stream through a wound and causes
muscles to constantly contract. This causes
painful muscle spasms and often leads to
death
F. Muscular Dystrophy
Hereditary disorder that causes muscle
weakness and atrophy. There are many
different types that affect different portions
of the body. The image shows Duchenne
or Becker MD (A), Emery-Dreifuss MD (B),
Limb Girdle MD (C), Facioscapulohumeral
MD (D), and Oculopharyngeal MD (E).
