microfilaments
Ciliary movement occurs in most of our internal tubular organs which are lined by
ciliated epithelium
The coordinated movements of ____ in the trachea help us in removing dust particles and some of the foreign substances
cilia
Passage of ova through the female reproductive tract is also facilitated by the
ciliary movement
Movement of our limbs, jaws, tongue, etc, requires
muscular movement
The ____ property of muscles are effectively used for locomotion and other movements by human beings

Based on their location, name three types of muscles identified
Which muscles are closely associated with the skeletal components of the body?
Skeletal muscles
Skeletal muscles have a striped appearance under the microscope and hence are called
striated muscles
