Question

what are involuntary mussels??? write their features in points ​

Answer 1

Involuntary Muscles :

• They are also known as Non-skeletal muscles

• They are found in visceral organs

• They don't have any transverse line, thus are also known as unstriated muscles.

• Their contraction and relaxation can not be controlled by will, thus they are also called Involuntary Muscles.

• Contractile fibres are found in cytoplasm.

• The contractile fibre is called myofibril.

• Autonomic nerves are connected to these muscles.

• They are spindle shaped.

• Their contraction period is much longer than any other muscle, but they remain contracted for a short period of time.

• The cells are connected by gap-junction.
