very big, very large, very great


a muscle that neutralizes or counteracts the effects of another muscle

Cardiac muscle

the muscle tissue of the heart


movable attachment of a muscle

I band

The region of the sarcomere made up only of thin filaments. The I band is bisected by a Z line. I bands alternate with A bands to give skeletal and cardiac muscle a striated appearance. I bands get shorter (and may disappear completely) during muscle contraction.


the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When its level is low, we feel hunger.

Immovable bone

origin of muscle??


A protein present in muscle fibers that aids in contraction and makes up the majority of muscle fiber; A type of protein filament that interacts with actin filaments to cause cell contraction.

Smooth muscle

a muscle that contracts without conscious control and found in walls of internal organs such as stomach and intestine and bladder and blood vessels (excluding the heart). involuntary muscle, not striated


attachment of a muscle that remains relatively fixed during muscular contraction


Connective tissue layer surrounding an individual muscle

Lactic acid

product of fermentation in many types of cells, including human muscle cells, causng the muscles to get sore

Movable bone

muscle's insertion


a contractile protein of muscle

Skeletal muscle

Voluntary, striated muscle that moves bones, works in pairs and is attached to bones by tendons

Oxygen debt

Respiration in the absence of sufficient oxygen leads to a build up of lactic acid that has to be cleared when sufficient oxygen is available.


thin connective tissue surrounding each muscle cell. (fiber?)

ATP (adenosine triphosphate)

main energy source that cells use for most of their work


muscles that contract simultaneously with the prime mover to facilitate more effective movement(helps execute movement or steady a part)


a band of fibrous tissue that connects muscle to bone


a neurotransmitter that triggers muscle contraction and affects learning and memory

Z band

actin attached to the ends of the sarcomere- the muscle fiber does not move but follows the contraction of the actin


cell membrane of a muscle cell
