What are the functions of the muscular system PDF?
Muscles allow a person to move, speak, and chew. They control heartbeat, breathing, and digestion. Other seemingly unrelated functions, including temperature regulation and vision, also rely on the muscular system. Keep reading to discover much more about the muscular system and how it controls the body.
What are the parts of muscular system and their functions?
They are:
- Skeletal: As part of the musculoskeletal system, these muscles work with your bones, tendons and ligaments. Tendons attach skeletal muscles to bones all over your body.
- Cardiac: These muscles line the heart walls.
- Smooth: These muscles line the insides of organs such as the bladder, stomach and intestines.
What are the 7 functions of the muscular system?
The main functions of the muscular system are as follows:
- Mobility. The muscular system’s main function is to allow movement.
- Stability. Muscle tendons stretch over joints and contribute to joint stability.
- Posture.
- Circulation.
- Respiration.

What is the basic function of all muscle tissue?
Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts.
How many parts are there in the muscular system?
There are about 600 muscles in the human body. The three main types of muscle include skeletal, smooth and cardiac. The brain, nerves and skeletal muscles work together to cause movement – this is collectively known as the neuromuscular system.
How many organs are in the muscular system?
There are over 700 organs in the muscular system. This is because the muscular system includes all the skeletal muscles of the body, the cardiac muscle, and the smooth muscles supporting the organs.
What are the functions of muscular tissue?
What is the main function of muscular tissue? Movement is the main function of muscular tissue. They have the ability to contract and this is what brings about the movement of body parts. They also help to maintain body posture and position.
Which is the longest muscle?
The sartorius muscle
The sartorius muscle is the longest muscle in the human body. It is strap-like, up to 600 mm in length, and contains five to seven neurovascular compartments, each with a neuromuscular endplate zone.
What are the 4 properties of muscles?
All muscle tissues have 4 characteristics in common:
- excitability.
- contractility.
- extensibility – they can be stretched.
- elasticity – they return to normal length after stretching.

Stapedius muscle said to be the smallest muscle in the body, but its not as small as its been described. Detailed awareness of the anatomy of stapedius muscle is needed so as to avoid confusion while facial nerve grafting and while drilling.
Which muscle is the strongest?
The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
What are 3 types of muscle tissue?
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
What is the major function of muscle?
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
What is muscle made of?
Muscle is made up of proteins called actin and myosin.
A muscle unit is a complex physiological structure that consists of a structure called a sarcomere, a nerve fiber supplying the sarcomere and surrounding connective tissue.
What’s the largest muscle?
The gluteus maximus is the largest muscle in the human body. It is large and powerful because it has the job of keeping the trunk of the body in an erect posture. It is the chief antigravity muscle that aids in walking up stairs. The hardest working muscle is the heart.
