1 point
These muscles are found in limbs.
These muscles do not show striations.
The muscle fibres are spindle-shaped tapering and uninucleate.
These muscles are involuntary.​

Answer 1

Answer:

The first option,

*THESE MUSCLES ARE FOUND IN THE LIMBS*

is the incorrect characteristic.

Answer 2

Smooth muscles are found in limbs is not the characteristic of smooth muscles.

Explanation:

• Smooth muscles are found in limbs is not the characteristic of smooth muscles.
• Active or skeleton muscles are located in the limbs, whereas involuntarily muscles are located in the lungs.
• Skeletal muscles are named for the fact that they are linked to the bone. They may be relocated at will.
• They have cylindrical muscles in them.
• Characteristic of smooth muscles:
• Smooth  muscles do not show striations is the characteristic of smooth muscles.
• Smooth muscle is involuntary movement because it lacks striations, wasn't under voluntary movements, contains only one nucleus per cell, and is attenuated at both ends.
• Only the heart has cardiac muscle tissue, and cardiac contractions circulate blood throughout the body and keep blood pressure in check.
• Smooth muscle fibers are spindle-shaped tapering and uninucleate.
• Silky myofibrils contain a single nucleus and are spindle-shaped (wide in the center and shortened at both ends, like a football).
• They are 30 to 200 m long (thousands of times shorter than skeletal muscle fibers) and produce their own soft tissue, colostomy.
• Smooth muscles are involuntary.​
• Smooth muscle fibers, with the exception of the cardiac, are located in the walls of empty internal organs (such as the liver, pancreas, and intestines), are spindle-shaped, and are under involuntary control.
