|
when dissecting a muscle, what is the outermost conenctive tissue wrapping that is encountered?
|
epimysium
|
|
|
what band of striation has only thin (actin) myofilamentes?
|
I band
|
|
|
what is tetanus?
|
means different things/in reference to muscle contraction, is a wave summation that produces a steady contraction/or a disease called "lockjaw"/ or a condition caused by deficiency of calcium ions in the extracellular fluid.
|
|
|
when is an isotonic muscle contraction + isometric muscle contraction.
|
isotonic:when is movement/ isometric is no movement. both requieres energy
|
|
|
what effect would a drug that inactivated acetylcholinesterase have on skeletal muscle contraction?
|
prolonged contraction or spastic paralysis because there would be not acetylcholinesterase to inactivate the acetylcholine which would remain bound with receptors to provide stimulus x contraction
|
|
|
what ion is necessary for myosin heads to bind with receptor sites on actin? why?
|
calcium ions because the presence of Ca changes the configuration of troponin + exposes the myosin binding sites on actin myofilaments
|
|
|
if muscle fibers + motor units obey the all-or none- principle, what accounts x the difference in contraction strenght when picking up a feather as compared to a book?
|
multiple motor unit summation where additional motor units are recruited to counteract the increased load
|
|
|
which is more effective in terms of ATP produced -anaerobic or aerobic respiration?
|
aerobic pathway yields nearly 20 times more ATP than anaerobic pathway
|
|
|
what are the horse rider's muscle?
|
the adductor muscles in the medial compartment
|
|
|
what is a powerful knee extensor?
|
the quadriceps femoris group that is used in climbing, running, raising from a chair.
|
|
|
what is the site for intramuscular injection
|
the gluteus medius
|
|
|
what superficial muscle is a synergist of the temporalis when chewing food?
|
masseter muscle
|
|
|
what muscle is an antagonist to the biceps brachii
|
triceps brachii
|
|
|
the muscle group on the posterior thigh region has what effect on movement at the knee? what is this muscle group? what group acts as an antagonist to this group?
|
the mastring muscle group on the posterior surface of the thigh flexes the knee,+ the antagonist is the quadriceps femoris group on the anterior surface of the thigh
|
