Each muscle is composed of many long, cylindrical fibres arranged in parallel arrays. These fibres are composed of numerous fine fibrils, called:
(1) Microfilament
(2) Myofibrils
(3) Microtubule
(4) Sarcoplasm
Identify the tissue shown in the diagram and match with its characteristics and its location:
(1) Skeletal muscle, shows striations and closely attached with the bones of the limbs
(2) Smooth muscles, show branching, found in the walls of the heart
(3) Cardiac muscles, unbranched muscles, found in the walls of the heart
(4) Striated muscles, tapering at both-ends, attached with the bones of the ribs
Myofibrils form long, cylindrical fibres whose arrangement is :
(1) Parallel
(2) Irregular
(3) Continuous
(4) Anti-parallel
The attachment of skeletal muscles to bones and that of one bone to another is due to :
(1) Ligaments and tendons
(2) Tendons and ligaments
(3) Cartilage and tendon
(4) Osteocytes and cartilage
What is wrong with respect to skeletal muscles?
(1) The striated skeletal muscle fibres are bundled together in a randomly fashion.
(2) A sheath of loose connective tissue encloses many bundles of muscle fibres.
(3) Skeletal muscle is partially attached to skeletal bones
(4) All are wrong
