Difference Between Striated Muscles and Smooth Muscles - Practice Questions & MCQ

Location-

• Skeletal muscles are found in limbs, body walls, pharynx, initial regions of the oesophagus.
• These are voluntary muscles i.e. they are under the control of an individual’s will. 

Structure- 

• These muscles fibres are found in the form of bundles.
• These are attached to the skeleton.
• A muscle fibre is an elongated cell. It is surrounded by sarcolemma ( plasma membrane of muscle fibre).
• These muscle fibres are multinucleated. Nuclei are irregularly scattered in the cytoplasm of muscle fibre which is called sarcoplasm. 
• In the sarcoplasm, tightly bound myofibrils are present.

Function- 
Skeletal muscles are under the control of an animal's will and their contraction causes movements.

Location-

• These muscles are found in the posterior part of oesophagus, stomach, intestine, lungs, urogenital tract, urinary bladder, blood vessels, iris of the eye, the dermis of the skin 
• These muscles never connect with the skeleton.
• These muscle fibres are elongated, spindle-shaped, containing an oval nucleus. 
• Striped muscles are involuntary muscle i.e. they are not under the control of an animal's will. 

Functions- 

• Unstriped muscles aid in peristalsis.
• Smooth muscle determines the flow of blood in the arteries.
• They regulate airflow in the lungs.
• Smooth muscles in arteries and veins are largely responsible for the regulation of blood pressure.
