This is the name for the membrane of a muscle fiber.
What is sarcolemma?
100
These are the two main myofilaments in a sarcomere.
What are actin and myosin?
100
Muscles attach to bone in at least this many places.
What are 2?
100
The name given to muscle cytoplasm.
What is sarcoplasm?
200
This muscle tissue is found in visceral organs.
What is smooth muscle tissue?
200
This is the sheath surrounding the muscle.
What is the epimysium?
200
A letter name given to the dark bands of the sarcomere.
What is the A band?
200
The muscle attachment to moveable bone.
What is insertion?
200
These are the three muscle tissue types.
What are skeletal, cardiac, and smooth?
300
This muscle tissue (as a muscle) is attached to bone and skin.
What is skeletal muscle tissue?
300
This is the sheath surrounding the fascicle.
What is the perimysium?
300
The smallest unite of contraction; composed of myofilaments.
What is a sarcomere?
300
The muscle attachment to immovable or less movable bone.
What is origin?
300
There are many of these "Powerhouses" spread throughout a muscle fiber to supply ATP.
What are mitochondria?
400
These two types of muscle tissue are striated.
What are cardiac and skeletal?
400
This is the sheath surrounding the individual muscle fibers.
What is the endomysium?
400
This ion is released from the sarcoplasmic reticulum and binds with troponin, causing it to change shape and move tropomyosin off the actin binding site.
What is calcium?
400
A type of attachment where muscle attaches directly to the bone.
What is direct (fleshy) attachment?
400
This smooth endoplasmic reticulum of muscle cells secretes secretes calcium.
What is the sarcoplasmic reticulum?
500
These two types of muscle tissue cells are called muscle fibers because they are elongated.
What are skeletal and smooth muscle tissue cells?
500
Part of a muscle, held together by the perimysium, that holds bundles of muscle fibers.
What is a fascicle?
500
During contraction, the globular heads of myosin bind with the actin site forming these.
What are cross bridges?
500
Rope-like collagen connective tissue used in many indirect attachments due to it's toughness and conservative size.
What is a tendon?
500
These tubes branch off of the sarcolemma, allowing the nerve-initiated electrical impulses to reach every sarcomere.
