◉ What composes the muscular system? Answer: Skeletal muscles
only
◉ What is the study of the muscular system called? Answer: Myology
◉ What are the 4 functions of muscles? Answer: 1. Movement
2. Stability
3. Control of body openings and passages
4. Heat production
◉ Muscular movements also serve various roles in ______________.
Answer: Communication
◉ Describe stability. Answer: Prevents unwanted movements, there
are some muscles known as the antigravity muscles that fight against
gravity that help us not fall over or slump.
◉ What percent of body heat is produced by skeletal muscles?
Answer: 85%
,◉ What is the endomysium layer? Answer: Thin sleeve of loose
connective tissue that surrounds each muscle fiber.
◉ The endomysium layer provides room for two things, what are
they? Answer: 1. Blood capillaries
2. Nerve fibers
◉ The endomysium also provides an __________ ______________
environment for the muscle fiber. Answer: extracellular chemical
◉ Relate the endomysium tissue and excitation. Answer: Excitation
of the muscle fiber depends on exchange of calcium, sodium, and
potassium ions across the endomysial tissue and the nerve end.
◉ What is the perimysium layer? Answer: Thicker connective tissue
sheath that wraps muscle fibers together in bundles called fassicles.
◉ What are fassicles? Answer: Bundles of muscle fibers together
◉ Are fassicles visible to the naked eye, and if so what do they look
like? Answer: Yes fassicles are visible to the naked eye, and they
appear as parallel strands.
◉ What does the perimysium carry? Answer: Larger blood vessels,
larger nerves, and muscle spindles
, ◉ What is the epimysium layer? Answer: The fibrous sheath that
surrounds the entire muscle
◉ What is the fascia? Answer: Sheet of connective tissue that
separates neighboring muscles or muscle groups from each other and
from the subcutaneous tissue.
◉ What are the two types of muscle attachments? Answer: 1. Indirect
2. Direct
◉ What is an indirect attachment? Answer: The muscle ends short of
its bony destination and the gap is bridged by a tendon.
◉ What is a tendon? Answer: Fibrous band or sheet
◉ What is direct attachment? Answer: There is so little separation
between muscle and bone that to the naked eye, the red muscular
tissue seems to emerge directly from the bone.
◉ What is the origin? Answer: The bony site of attachment at the
relatively stationary end.
◉ What is the insertion? Answer: Attachment site at its more mobile
end
