|On the basis of structure:|
|Cells are cylindrical||Cells are long||Cells are cylindrical|
|Cells are not branched||Cells are not branched||Cells are branched|
|Cells are multinucleate||Cells are uninucleate||Cells are uninucleate|
|Alternate light and dark bands are present||There are no bands present||Faint bands are present|
|Its ends are blunt||Its ends are tapering||Its ends are flat and wavy|
|On the basis of location:|
|These muscles are present in body parts such as hands, legs, tongue, etc.||These muscles control the movement of food in the alimentary canal, the contraction and relaxation of blood vessels, etc.||These muscles control the contraction and relaxation of the heart|
Functions of areolar tissue:
→ It helps in supporting internal organs.
→ It helps in repairing the tissues of the skin and muscles.
Three features of cardiac muscles are:
→ Cardiac muscles are involuntary muscles that contract rapidly, but do not get fatigued.
→ The cells of cardiac muscles are cylindrical, branched, and uninucleate.
→ They control the contraction and relaxation of the heart.
The specific function of the cardiac muscle is to control the contraction and relaxation of the heart.
The outer protective layer or bark of a tree is known as the cork. It is made up of dead cells. Therefore, it protects the plant against mechanical injury, temperature extremes, etc. It also prevents the loss of water by evaporation.
The three types of muscle fibres are:Striated muscles, smooth muscles (unstriated muscle fibre), and cardiac muscles.
