Question | Answer |
muscle cells | muscle fibers |
the ability of skeleton muscle to shorten with force | contractility |
raises the eyebrows | occipitofronatals |
moves the tongue | extrinsic tongue muscles |
neck muscles | sternocleidomastoid |
thin myofilaments | actin myofilaments |
a connective tissue located outside the epimysium | fascia |
the ability to be stretched | extensibility |
the capacity of skeletal muscle to respond to a stimulus | excitability |
ability to recoil to original resting length after being stretched | elasticity |
skeletal muscles are surrounded by a connective tissue called | epimysium |
single muscle cells are called | fibers |
each fiber is surrounded by a connective tissue | endomysium |
a threadlike structure that extends from one end of the fiber to the other | myofibrils- |
think myofilaments | myosin myofilaments |
actin and myosin myofilaments from highly ordered units | sarcomeres |
charge difference across the membrane | resting membrane potential |
the brief reversal back of the charge | action potential |
nerve cells that carry action potentials to skeletal muscle fibers | motor neurons |
connection to the muscle forms a, blank, near the center of the cell | neuromusclular junction or synapse |
one single motor neuron and all the skeletal muscle fibers it innervates | motor units |
many motor units from how many muscles | single muscle |
is formed by an enlarged nerve terminal | neuromuscular |
the enlarged nerve terminal is called | presynaptic terminal |
the spaces between the presynaptic terminal and the muscle cell is the | synaptic cleft |
and the muscle fibers are called | postsynaptic terminal |
each presynaptic terminal contains | synaptic vesicles |
the synaptic vesicles that secrete a | neurotransmitter |
the synaptic vesicles that secrete a neurotransmitter called | acetylcholine |
when an action potential reaches the nerve terminal it causes the synaptic vesicles to releases | acetylcholine |
when an action potential reaches the blank it causes the synaptic vesicles to releases | nerve terminal |
when an action potential reaches the nerve terminal it causes the blank to releases acetylcholine | synaptic vesicles |
the blank diffuses across the synaptic cleft | acetylcholine |
the acetylcholine defuses across the | synaptic cleft |
the combination of acetylcholine with its receptor causes an | influx |
the combination of acetylcholine with its receptor causes an influx of what | sodium ions |
the sodium ions reflects into the | muscles fibers |
is a contraction of an entire muscle in response to a stimulus | muscle twitch |
closes the eyelid | orbiculoris oculis |
puckers the mouth | orbicularis oris |
flattens the cheek | buccinator |
smiling muscle | zygomatics |
sneering muscles | levator labii superiors |
frowning | depressor anguli oris |
chewing | mastication |
4 pair of muscles used for chewing | temporalis, masseter, 2pterygoid |
changes the shape of the tongue | intrinsic tongue muscle |
moves the tongue | extrinsic tongue muscle |
prime mover of the neck | sternocleidomastoid |
wry neck | torticollis |
single sheet like a muscle that covers the antero lateral neck | platysma |
platysma single sheet like a muscle that covers the antero lateral neck | antero lateral neck |
group of muscle that is on each side of the spine | erctor spinal |
draw scpaula toward veit column | rhomboids |
flexs, extends and abducts the arm | deltiod |
contract durning fored expiration | internal intercostal |
"abs" | rectus abdominis |
muscles that work together are called | synergists |
what does oblique mean | at a 45 degree angle |
2 types of contraction | isotonic and isomatric |
