Back 6

1 Allows movement via attachment of bone to muscle. 2 Nervous system 3 Rapidly. 4 Single, Striated and very long multinucleate cells. 5 Large amounts of force

Front 7

1. What is the function of the cardiac muscle? 2 Describe the regulation and contraction. 3 Describe its cell shape and appearance. 4 How fatigue is it? 5 describe the force of this muscle?

Back 7

1 Pumps blood for oxygenization as well as systemic circulation. 2 self excitatory but influenced by nerves and hormones. 3 Branching striated uninucleate or binucleate ;all cells are connected directly or indirectly. 4 Less fatigue than skeletal muscle. 5 left ventricle strong enough to pump blood to all parts of body during exercises

Front 8

1. What is the function of the smooth muscle? 2. Describe the regulation of contraction. 3 Describe the cell shape and appearance. 4 how is its fatigue levels? 5 how much force does it produce

Back 8

1. Regulates pressure in blood vessels; allows for peristalis in digestive system. 2 contracts and relaxes slowly and is able to sustain contraction. 3 uninucleate;single fusiform cells. 4 Generally does not fatgue. 5 generates the least amount of force

Front 9

1 Define the sacromere. 2 what are the seven sacromere components.

Back 9

1 The basic unit of skeletal muscle tissue. 2 Actin, Myosin, Z band, Isotropic band, anisotropic band h-zone, and m line.

Front 10

1 Define actin. 2 what is the function of myosin? 3 what is located along the sacromere border? 4 The isotropic band contains what only? 5 what does the anisotropic band contain? 6 What is the function of the m line?

Back 10

1 primary component of thin filaments along with trypomyosin and troponin. 2 Slide between actin filaments during contraction. 3 Z band. 4 Actin. 5 actin and myosin. 6 connects neighboring strands of myosin.

Front 11

1 what are myofibrils made of? 2 what are muscle fibers (myocyte/muscle cells) made of? 3 what are fasicles made of and what surrounds it? 4 what is made of several fasicles in parallel?

Back 11

1 Several sacromeres in series. 2 several myofibrils in parallel; multinucleated; surrounded by endomysium. 3 multiple muscle fibers in parallel; perimysium. 4 muscle

Front 12

1 Describe endomysium. 2 what surrounds the fasicle. 3 Describe the epimysium. 4 The tendon is the site of what attachment? 5 what are the four functions of muscles?

Back 12

1 sheath of dense connective tissue that surrounds each muscle fiber. 2 perimysium. 3 surrounds muscle; thickens into tendons at site of connection to bone. 4 muscle attachment to bone. 5 Movement, generation of force, storage of glycogen, and orientation in space via muscle spindles and golgi tendon organs

Front 13

1 Define hypertrophy. 2 define hyperplasia. 3 blank is gradual muscle wasting. 4 Define rhabdomyosis, what can it result in, who can it be seen in?

Back 13

1 muscle growth via an increase in the size of muscle fibers and is common in humans. 2 Muscle growth via an increase in the number of fibers and is common in cats. 3 Atrophy. 4 Extremely rapid breakdown of muscle tissue, victims of earthquakes and bombings.

Front 14

1. Where can the catch muscle be found, what does it specialize in? 2 what type of insect uses the asychnous muscle and what for? 3 How does the asynchnous muscle contract? 4 what does asynchnous muscle contraction result? 5 Does the asynchnous muscle have more or less power output and describe its restriction in function?

Back 14

1. Molluscs, maintaning tension with low ATP expenditures. 2 Beetle for flapping its wings. 3 more than one contraction per nerve pulse. 4 attachment to resonant structure . 5 More efficient power output but less restricted in function

Front 15
