Muscle System

WHAT IS THE FUNCTION OF MUSCULAR SYSTEM?

The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight.

Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.

WHAT IS MUSCULAR SYSTEM?

The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture and circulates blood throughout the body. The muscular systems in vertebrates are controlled through the nervous system although some muscles can be completely autonomous.

LARGEST MUSCLE

Guteus maximus:- 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.

Gluteus Maximus the largest and heaviest muscle in the body. It is the most superficial of all gluteal muscles that are located at the posterior aspect of the hip joint. This makes it the largest muscle at the hip representing 16% of the total cross-sectional area (TCSA).

LONGEST MUSCLE

The longest muscle in the body is the sartorius muscle, which runs diagonally down the thigh. It stretches from the outer side of the hip bone down to the inside of the knee bone. The sartorius can be up to 23 inches (60 centimeters) in length, according to a 2005 paper.

SMALLEST MUSCLE

Stapedius muscle is termed to be the smallest skeletal muscle in human body, which has a major role in otology. Stapedius muscle is one of the intratympanic muscles for the regulation of sound.

The smallest muscle in the human body is the stapedius, which controls the stapes in the ear. The muscles is less than 1.27 mm (0.05 in) long.
