Solution
The correct option is D A, B and E statements are wrong.
Voluntary muscles are under the control of the will and is generally attached to the skeleton. An individual muscle consists of bundles of long muscle fibres, each bounded by a sarcolemma and containing sarcoplasm, sarcoplasmic reticulum, and many nuclei. Ex - Biceps.Neuroglial cells protect and support the neurons. Blood cells secrete fibrin that helps in clotting during an injury or a wound.
So the correct option is 'A, B and E statements are wrong'.
