Summary Introduction

Introduction :

There are three types of muscle tissues namely; skeletal, smooth and cardiac muscles. Muscle tissues are characterized by the presence of elongated cells called muscle fibers, that can contract to create bodily movements.

Answer to Problem 1PL

Correct answer :

The correct answer is option (a) Skeletal.

Explanation of Solution

Explanation/justification for the correct answer :

Option (a) Skeletal. Skeletal muscle cells are long, thread-like, multinucleated and striated with an organized pattern of contractile proteins. These muscles are usually attached to bones and have functions such as body movements, maintaining posture, heat production and providing protection. Skeletal muscles are under conscious control and are considered voluntary. So, the correct answer is option (a).

Explanation for incorrect answer :

Option (b) Smooth. Smooth muscle cells are not striated and are fusiform in shape with the nucleus located to its center. It is located in visceral organs; iris, blood vessels, and respiratory tubes and has functions such as the motion of visceral organs (peristalsis), controlling pupil size and blood flow. Smooth muscle is under involuntary control. So, this is an incorrect option.

Option (c) Cardiac. Cardiac muscle is located only in the heart wall and the cells are branched, striated and have a single nucleus. It is under involuntary control. So, this is an incorrect answer.

Option (d) Stomach. Smooth muscle forms the walls of hollow internal organs. The stomach is made with smooth muscle, which is under involuntary control and functions to pump blood. So, this is an incorrect answer.
