Ch 8--Muscular System Flashcards
Involuntary muscle
Heart.
Performs without conscious command
Muscle types
Skeletal muscles-movement
Cardiac muscles-heartbeat
Visceral muscles-breathing, digestion
Ligaments
Connective tissue that connects bones to other bones
Tendons
Connective tissue that connects muscles to bones
Biceps brachii
Muscle that moves the forearm.
Lies over the humerus and is attached at one end to the scapula
Origin
The point of attachment of the biceps to the scapula. Term is used for muscles attachment to the bone that does not move when muscle contracts
Insertion
