|
|
|
Only in the heart, moves through chambers and into the circulatory system. |

40-45% |
|
|
|
Limited capillary blood flow for a runner means? |
Give a pre-event massage for optimal performance. Progressive knee pain is a build up of toxins. |
|
|
|
Looks like a long worm structure and are also referred to as muscle fibers. |
Muscle cell |
|
|
|
Four characteristics or functions of muscles. |
Contractility, extensibility, excitability/ irritability |
|
|
|
Contractility |
To contract or shorten as a result, exert force |
|
|
|
Contractility |
To contract or shorten as a result, exert force |
|
|
|
Extensibility |
The ability of the muscle to stretch |
|
|
|
Elasticity |
Muscles ability to return to its original state |
|
|
|
Excitability/irritability |
(Mechanical, thermal, chemical, nervous impulses) ability to receive and react to stimuli |
|
|
|
How many types of muscle contractions? |
2 |
|
|
|
Isometric |
Contraction generates force without changing the length of the muscle |
NO MOVEMENT |
|
|
Isotonic |
When the muscle shortens (concentric), when the muscle lengthens (eccentric) |
MOVEMENT |
|
|

3 |
Cardiac, skeletal, smooth smoothe |
|
|
A muscle that moves food through intestines, blood etc... |
Smooth |

Smooth |
|
|
|
Muscle only found in the heart |
Cardiac |
|
|
|
This muscle moves bones at joints, and the whole body |
Skeletal |
|
|
|
Non-striated muscle |
Has no stripes but a nucleus (digestive system) key word |
It’s a smooth muscle |
|
|
Is striated (has stripes) has nuclei, contracts 3 billions times involuntary |
Cardiac muscle |
|
|
|
A striated (has stripes) has nuclei and is connected to bones, fibers aka tendons |
Skeletal |
|
|
|
Superficial muscle is where |
Not deep lol |

|
|
Skeletal muscles have two fibers. Name the two |
Type 1- slow twitch- posterior Type 2- fast twitch- only in arms and legs |
|
|
|
Tendons connect to? |
Like glue and connect muscle to bone |
|
|
|
Tendons connect to? |
Like glue and connect muscle to bone |
|
|
|
Ligaments connect? |
Bone to bone |

Covers an individual muscle with connective tissue |
|
|
|
(Skeletal) Epimysium |
Covers an individual muscle with connective tissue |
|
|
|
(skeletal) Perimysuim |
Extends inward from epimysium and separates muscles into bundles called fascicles |
|
|
|
(Skeletal) endomysium |
Covers each muscle fiber within the fascicles with a delicate connective tissue |
|
|
|
(Skeletal) endomysium |
Covers each muscle fiber within the fascicles with a delicate connective tissue |

|
|
Easy sources to get food for muscle contraction? |
ATP (oxygen, glucose and fats or protein) |
|
|
|
“Power Plant” |
Mitochondria |
|
|
|
Forms ATP for muscle cell contraction |
Mitochondria |
|
|
|
When an impulse from the brain or spinal cord reaches the end of the motor neuron? |
Contraction |
|
|
|
Neurotransmitter aka |
Neuron chemical or acetylcholine |
|
|
|
Acetylcholine does what? |
Stimulates the muscle cell membrane resulting in an impulse |
|
