TYPES OF MUSCLES TYPES OF MUSCLES
Cardiac muscle fibers have
intercalated discs for
synchronized contraction,
regulated by the heart's intrinsic
conduction system. The muscle
adapts to body demands like
exercise, aiding in involuntary
movements like the heartbeats
and essential bodily functions.
Skeletal muscles with striped
fibers connect to bones via
tendons. Actin-myosin dance
makes muscles move. Brain
signals control muscle actions.
Skeletal muscles enable
voluntary movement, posture,
and joint stability. Exercise keeps
muscles strong and healthy.
SKELETAL MUSCLES SKELETAL MUSCLES
CARDIAC MUSCLE CARDIAC MUSCLE
Smooth muscle fibers are spindle-
shaped with a singular nucleus, aiding in
involuntary movements in organs like
the intestines and blood vessels.
Contractions help with functions like
peristalsis and blood flow regulation,
essential for maintaining internal
balance.
