Difference Between Striated Muscles and Smooth Muscles MCQ

Quick Facts

Unstriped or Non-striated or Visceral or Smooth or Involuntary Muscle is considered one of the most asked concept.
20 Questions around this concept.

Striped or Striated or Skeletal or Voluntary Muscle

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.

Unstriped or Non-striated or Visceral or Smooth or Involuntary Muscle

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.
