the long, slender cells that make up muscles
a muscle that is connected at either or both ends to a bone and so move parts of the skeleton
a muscle that is under conscious control
Connective tissue surrounding a fascicle
A discrete bundle of muscle cells
Connective tissue surrounding a muscle fiber
tissue that connects muscle to bone
broad, fibrous sheets of connective tissue
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)
the muscle tissue of the heart
enables movement of the body and internal organs
an extensible membrane enclosing the contractile substance of a muscle fiber
Micorsopic, fiber-like structures that occupy most cytoplasm in skeletal muscle cells
both actin and myosin
The smallest functional unit of muscle tissue
AKA thick filaments, A Protein that makes up nearly half of the proteins in muscle cells
AKA thin filaments, A globular protein that links into chains, two of which twist helically about each other, forming microfilaments in muscle and other contractile elements in cells.
are formed when tail of myosin molecule, which consists of 2 intertwined helical polypeptide heavy chains, contract and link the thick and thin filaments together; the gobular heads, are business end of myosin;
corresponds to endoplasmic reticulum, network of membranous channels that surround each myofibril and runs parallel to it
