Verified By Collegedunia

The Correct Option is C

Solution and Explanation

Skeletal or striated or voluntary muscles are found in the limbs, body wall, tongue, pharynx and beginning of oesophagus. These muscles are under the control of animal's will. Smooth or nonstriated or involuntary muscles are found in the posterior part of the oesophagus, stomach, intestine, lungs, urinogenital tract, etc. Action of these muscles is controlled by autonomic nervous system and they are not under the control of animal's will. Cardiac muscles are found in the wall of the heart. Their fibres show the characters of both unstriped and striped muscle fibres and are involuntary.

Notes on locomotion and movement

Concepts Used:

Locomotion and Movement

Locomotion

The movement of a creature from one place to another is known as locomotion. During the process, there is the action of appendages such as wings, limbs, and flagella. In some animals, like fish, whales, and sharks, locomotion upshots from a wave-like series of muscle contractions. Locomotion helps an organism in finding their food, avoid harsh weather conditions, escape from their predators, etc.

Some examples of locomotion are walking, running, swimming, etc. Movement, on the other hand, refers to any type of motion that need not be localized.
