Isolated function
Action of a muscle when generating an eccentric contraction - example lowering an arm after a bicep curl to prevent gravity from pulling it off
Eccentric function
Division of the nervous system
comprising the brain and the
spinal cord; primary function
is to coordinate activity of all
parts of the body.
Central Nervous System
All of the nerve fibers that
branch off from the spinal
cord and extend to the rest
of the body
Peripheral Nervous System
Functional unit of the nervous system
Neuron
Sensory receptors responsible for sensing change of
position in body tissues.

Golgi tendon organs
Tubular component of muscle cells containing sarcomeres and protein filaments
Myofibrils
Slow-twitch that have high aerobic capacity. They are more resistant to fatigue. They do not respond well to muscle growth, are smaller in size, and produce less force
Type I
Individual contractile units
made up of actin (thin) and
myosin (thick) filaments
Sarcomeres
Meaning “with oxygen,” the
long-term energy production
cycle that occurs when
sufficient oxygen is present
Aerobic

prime mover of a joint
exercise. - example: gluteus maximus at the hip during a squat
Agonist
Muscles that assist the prime
mover in a joint action. Example - piriformis at the hip during a squat
Synergists
Fast-twitch that have less oxygen delivery due to less capillaries. Considered to be anaerobic and more susceptible to enlargement. Produce more speed and strength, but the burst of intensity is short-lived. Quick to fatigue
