Anatomy: Introduction to Myology Flashcards
the connection between a muscle and a tendon is called
musculotendinous junction (MTJ)
the connection between a tendon and a bone is called the
tendoperiosteal junction (PTJ)
the ______ is the central portion of the muscle (the meat of it)
belly
_____: one of at least 2 extensions of a particular muscle belly that attaches via its own tendon
head
___________: A sheet-like tendon
Aponeurosis
when the tension is greater than the resistance, the muscle undergoes a shortening or _____________________
concentric contraction
a _________________ pulls the two attachments closer together
concentric contraction
when a muscle contracts against a resistance and there is no visible change in the muscle length (its attachments are NOT drawn together or pulled apart), it is called an _________________
isometric contraction
when a muscle is generating force but is unable to overcome the force, the muscle will undergo a lengthening or _________________
eccentric contraction
Muscle attachment reference: the attachment that is fixed is sometimes called the _____
origin
Muscle attachment reference: the attachment that is moving is sometimes called the__________
insertion
the primary muscle causing the desired movement:
primary mover
prime mover for knee extension?
quadriceps
the muscle that opposes a specific action
antagonist
the muscles that stabilize the more proximal joints during actions of the more distal joints:
Stabilizers AKA fixators
the muscle(s) that works to assist the prime mover in a given action:
Synergists AKA neutralizers AKA neutralizing synnergists
connective tissue that runs throughout the body to provide structure and support:
fascia
