Causing a sensor in the brain to react to the spinal cord
What is the sarcolemma?
What is the cytoplasm of the muscle cell?
Actin

Sarcoplasm
What is the Muscular System?
What are the 4 functions of muscles?
Movement, Transportation of fluids, Posture and Joint stability, and Producing Heat
Actins, contractions, Myosins, and Mytosins.
Movement, Transportation, Stability, and Mobility
Stability, Producing heat, regulating body temperature, and transporting fluids.
Isometric contraction occurs when a muscle contracts without causing any movement
True
False
What Is Concentric Contraction?
When a muscle moves and causes a muscle spasm.
When your nerves move apart to create muscle movements, or contractions.
when a muscle contracts without causing any movement
when a muscle shortens as it contracts causing articular movements.
What is an Ecentric Contraction?
when a muscle shortens as it contracts causing articular movements.
When a muscle contracts without causing any movements
When a muscle gradually releases as it elongates.
When a muscle contracts causing a muscle spasm.
What Is an SO Fiber or (oxidative)
Fibers are generated in short-term sprints or "power" activities that fatigue slowly.
Quick and rapid muscle contractions that fatigue quickly
Muscle fibers that cause grip strength.
What Is an FG fiber (Glycolytic)
Muscle movements or contractions that cause the fibers to speed up movement of the muscles.
Generate short-term-sprints, or power that fatigues muscles after a long period of time.
Generate energy rapidly for quick powerful contractions that fatigue the muscle quickly.
The muscle ____ is attached to the immovable or stationary bone (Bicep to Humorous.
Hamstring
Origin
Actin
Type
What Is a muscle Insertion?
Where the bones stretch away from one another when a muscle contraction occurs.
When two bones collide against one another when the body is in motion.
Where the muscle moves near a movable bone.
Where the muscle attaches to a movable bone.
What are the two types of muscle contractions ?
Isometric and Isolated
Isometirc and Isotonic
Isotonic and Isolated
Imperial and Anterial
What Is Muscle Tone?
What is the Sliding Filament theory ?
When triggered by a nerve impulse, the actin filaments slide toward one another, shortening the sarcomeres causing a contraction in the muscle.
When signaled by a nerve impulse, the myosin reactions slide away from one another, elongating the sarcomeres causing a contraction in the muscle.
When a muscle contraction occurs due to im likes in the brain.
Muscle contractions DO NOT require ATP.
True
False
muscles produce movement by _______.
creating actins.
Contracting ATP
colliding with bones
pulling on bones.
About what percentage of your body is made up of muscle ?
30%
25%
50%
65%
What are the characteristics of a muscle tissue ?
Contracting, Extensibility, Elasticity, and Irritability
Contracting, Elongating, and Mobility
Evaporation and contraction
Extensibility, Flexibility, Contraction, and Irribility.
What is the function of Skeletal Muscle?
To keep a stabilized bone figure
Allows movement, and attaches to the bone as well as allows concious control.
Generates and conducts electrical impulses.
Involuntary muscle
Muscle is made up of fibers.
True
False
What is the all or nothing principle ?
What type of exercise results in stronger more flexible muscles with greater resistance to fatigue ?
Isometric Exercise
Aerobic Exercise
Lactic Exercise
Mental Exercise
Muscles attach to bones at _______ or more.
2
3
4
1
Lactic Acid fermentation may occur during rigorous exercise due to low oxygen levels (oxygen debt) in the muscle cells.
True
False
What are the two types of myofilaments?
filament, and anti-filament
Thick Filaments(Myosin) and Thin Filaments(Actin)
Mytosis, and osmosis
