: Muscles of the heart are striatedbranched and involuntary. The muscle layer of the heart is called as myocardium. It is responsible for the pumping of the heat.

The skeletal muscle fibre is a 'syncytium'which means it is
1 made up of many fibres
2 made up of many proteins
3 long and slender
4 swollen in the middle with tapered ends
5 multinucleated
Explanation:
: Skeletal muscle fiber is "syncytium" which means it is multinucleated. They are commonly called muscle fibresare multinucleated syncytia formed during development by the fusion of mononucleated precursor cells called the myoblasts.

Muscle tone' is defined as:
1 voluntary resistance to passive strength
2 involuntary resistance to passive strength
3 stimulated resistance to passive strength
4 none of these
Explanation:
C Muscle tone is defined as stimulated resistant to passive strength. It is important for generating reflexesmaintaining posture and balance etc. Muscle tone is regulated by the activity of the motor neurons and can be affected by various factorslike agedisease and nerve damage.

Which of the following muscle types CANNOT be used voluntarily?
1 Both striated and smooth
2 Both cardiac and striated
3 Both smooth and cardiac
4 Cardiacstriated and smooth
Explanation:
C Cardiac muscle are found in the heart wall. It is an involuntary muscle that is responsible for the pumping action of the heart. Smooth muscle has no striations which is not under voluntary controlhas only one nucleous per cellwhich is tapered at both ends and is called involuntary muscle. Both smooth muscle (unstraited muscle) and cardiac muscle are functionally involuntary.
