Facts about muscles
The muscular system is a fascinating part of our bodies. Muscles are necessary for all the little movements we do, like blinking, and for big movements, such as running or throwing. Some muscles we control, like the bicep when we’re taking the shopping out of the car. Other muscles, such as those that help you breathe, move without us thinking about it at all. The following are some interesting facts about muscles.
Muscles are divided into three types: smooth, cardiac and skeletal
Smooth muscles are involuntary muscles in your gut, blood vessels or anywhere else that work without you thinking about making them move.
Cardiac muscles are in your heart.
Skeletal muscles are attached to the bone and help you with everyday activities like sitting, walking, and typing.
Your body has more than 600 muscles
Some of these muscles you can feel like your arms and legs. Others are deep inside the body like the one that keeps your heart beating and those that help you digest food.
Muscles are made up of special cells called muscle fibres
The main quality of these muscle fibres is contractibility. This means the muscles can shorten or lengthen as needed. Almost all movement in your body happens because of muscle contractibility.
The largest muscle in the body is the gluteus maximus
It’s the main extensor muscle of the hip, otherwise known as the large muscle of the buttocks. It’s the largest muscle because its job is to support the trunk and maintain proper posture. The gluteus maximus is the main muscle used to help you walk upstairs.
The smallest muscles are in your inner ear
Just as the smallest bones are found in the ear, the same applies to muscles. These muscles connect your eardrum and hold your inner ear together.
The strongest muscle is….
You may have heard that the tongue is the strongest muscle in the body. However, as there are many ways to measure muscle strength, it is too hard to determine which muscle is in fact the strongest. The calf muscle puts out the most force when used and the jaw muscle exerts the most pressure. The masseter is a muscle in your jaw. It can close your teeth with a force as great as 90kgs on your molars.
The hardest working muscle is…..
The heart is the hardest working muscle pumping approximately 7500 litres of blood and beating 100,000 times per day. The heart muscle is also the only muscle that never tires.
Some of the busiest muscles are located in…..
The eyes! These muscles are constantly making adjustments as you read, drive, watch TV or just looking around. In just one hour of reading your eyes may make as many as 10,000 coordinated movements.
Muscles are built during sleep
Going to the gym and lifting weights build muscle strength. It is during sleep that muscles actually grow. When in deep sleep mode, all those hardworking muscles can relax allowing for more blood circulation.
