Question :
Assertion (A): Striated muscles are attached to the bones in different parts of body.
Reason (R) : These are independent of voluntary control.
Answer:
Striated muscles are attached to the skeletal parts of the body and help in locomotion,posture,support and in turn maintaining homeostasis. As these muscles are found in proximity to skeleton,they are also known as Skeletal Muscles
Thus, (A) is correct
In contrast to the reason given,striated muscles are under the voluntary control of Central Nervous System
Thus, (R) is wrong
The real reason behind their striated appearance is :
Skeletal Muscles are characterized by the presence of myosin and actin filaments. Myosin occurring region is known as Anisotrophic Band or simply A Band while the actin occurring region is known as Isotrophic Band or I Band. These bands occur alternatively giving the striated appearance
