Muscular Flashcards
Attached to bones
or, for some facial
muscles, to skin
SKELETAL
Walls of the heart
CARDIAC
Mostly in walls of
hollow visceral
organ (except the
heart)
SMOOTH
occurs when muscle contract
across joints.
Body movement
A movement that decreases
the angle of the joint and
brings two bones closer
together.
FLEXION
A movement that increases
the angle, or the distance,
between two bones or parts of
the body.
EXTENSION
A movement of a bone
around its longitudinal axis.
ROTATION
movement towards midline of body
adduction
movement away from midline
abduction
A combination of flexion,
extension, abduction, and
adduction commonly seen in
ball-and-socket joints such as
the shoulder
CIRCUMDUCTION
Movement of the
top of the foot
toward the anterior
aspect of the shin.
DORSIFLEXION
Movement of the
sole of the foot
away from the
anterior tibia.
PLANTAR FLEXION
plantar
surface of the foot
inward toward the
midline.
INVERSION
tilting
the plantar
surface
outward and
away from the
midline
EVERSION
hand faces
anteriorly
SUPINATION
hand faces
posteriorly
PRONATION
Combined movement of
abduction, flexion, and medial
rotation of the thumb
OPPOSITION
major
responsibility for
causing a particular
movement
PRIME MOVER
oppose or
reverse movement
ANTAGONISTS
Help prime movers
SYNERGISTS
Specialized synergists
FIXATORS
Fascicles converge toward a
single insertion tendon.
CONVERGENT
Fascicles are arranged in concentric
rings.
CIRCULAR
Result in a spindle-shaped muscle
with an expanded belly.
FUSIFORM
