THE MUSCULAR SYSTEM
5 major properties
2) Contractible
After receiving
stimulation
they are
capable
of
shortening
5) Adaptability
Muscles can be changed depending on how they are
trained
1) Excitable or irritable
capable of
reviving
stimulation and
responding
to
stimulation
from the
nerves
3) Extensible
Muscles can be
stretched
without damaged by
applying force
4)Elasticity
Muscles can return to
original
resting shape
and length
after being extended
or
contracted
5 Types of Muscle Movements
1) Adduction
Moving a body part towards the mid-line of the body
3) Flexion
Decreasing
the angle at a joint
4) Extension
Increasing
the angle at a joint
5) Rotation
Moving a body part around an axis
2) Moving of a body part
away
from the mid-line of the body
3 Main types of muscle
2) Visceral/smooth Muscles
Involuntary Muscles
Found in
organs
or
organ systems
e.g digestive or respiratory system
1) cardiac muscle
Involuntary muscle
operates without any conscious control
Form the walls of the heat
3) skeletal muscles
voluntary Muscle
Attatched to the skeleton and provide skeleton with ability to move
supportive structures
Fascia
Attach
muscle
