Question

Total number of muscles in our body is:
A. 256 muscles
B. 639 muscles
C. 400 muscles
D. 421 muscles

Answer 1

Hint: In the typical human body, almost every muscle has one part of a pair of identical bilateral muscles found on both sides of the body.

Complete answer:
1. Muscles are the soft tissues present in the human body. These are the only kinds of tissues that are able to contract and therefore responsible for the movement, which is their primary function.
2. There are around 639 skeletal muscles. Since different sources group muscles differently it is difficult to define the exact number.
3. Muscles help maintain the posture of the body by helping it contract and expand according to body requirements. These tissues have great endurance.
4. Muscles are also responsible for the movement inside the body. Different kinds of muscles are responsible for different kinds of movements even inside the body, for instance, the primary function of cardiac and visceral muscles, transportation of blood and food.
5. Muscles also help generate body heat through metabolic reactions that take place during muscle movement. Generation of excess body heat may cause sweating.

Hence, the correct answer is option B.

Note: Muscles are made up of soft tissues. There are three types of muscle tissues, namely, visceral, cardiac, and skeletal muscle tissues.
1. Visceral muscles are the weakest muscle tissues and are found inside the organs like the stomach, blood vessels, etc.
2. Cardiac muscles, as the name suggests, are found inside the heart and are responsible for pumping blood.
3. The skeletal muscles are the only voluntary muscle tissues found inside the human body. These are responsible for locomotion and movement such as speaking, walking et cetera.
