Describe myosin. correct answers Myosin is a myofilament that is known as the "thick filament".

, micrometers). The myosin filaments consists of a globular head, a hinge point, and a fibrous tail
(Ch. 1)
Describe actin. correct answers Actin is a myofilament that is known as the "thin filament". It is
about 6 nanometers in diameter (0.006 micrometers) and is arranged in a double helix (Ch. 1)
What is a sarcomere? correct answers The smallest contractile unit of a skeletal muscle made up
of actin and myosin myofilaments (Ch. 1)
About how big is a sarcomere? correct answers About 2.5 micormeters in length (Ch. 1)
Where do adjacent myosin filaments meet? correct answers At the M-bridge of the sarcomere
(Ch. 1)
Where do adjacent actin filaments meet? correct answers At the Z-line of the sarcomere (Ch. 1)
How many actin filaments surround each myosin filament? correct answers Six (Ch. 1)
How many myosin filaments surround each actin filament? correct answers Three (Ch. 1)
What does a sarcomere look like? correct answers There are five main components: the A-band,
the I-band, the Z-line, the M-line, and the H-zone (Ch. 1)
Describe the A-band of a sarcomere. correct answers This component corresponds with the
alignment of the myosin filaments. Both myosin and actin are present (Ch. 1)
Describe the I-band of a sarcomere. correct answers This is the line where two adjacent
sarcomeres meet. Only actin is present (Ch. 1)
Describe the Z-line of a sarcomere. correct answers Sits in the middle of the I-band and anchors
actin filaments (Ch. 1)
Describe the M-line of a sarcomere. correct answers Sits in the middle of the H-zone and anchors
myosin filaments (Ch. 1)
Describe the H-zone of a sarcomere. correct answers The area of the sarcomere where only
myosin is present (Ch. 1)
What is the sarcoplasmic reticulum? correct answers Lie parallel to each myofibril as an intricate
system of tubules. It terminates as vesicles in the vicinity of the Z-lines (Ch. 1)
What do the vesicles at the end of the sarcoplasmic reticulum contain? Why is this important?
correct answers They contain calcium, whose regulation controls muscle contraction (Ch. 1)
