What’s the strongest muscle in your body?
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 does Mascular mean?
In botany, relating to stamens: same as male and masculine.
Is a muscle an organ or tissue?
A whole skeletal muscle is considered an organ of the muscular system. Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue.
What happens if the muscular system fails?
If your muscles lose function, you won’t be able to properly operate the affected parts of your body. This symptom is often the sign of a serious problem in your body, such as a severe injury, drug overdose, or coma.
What are joints?
What Are Joints and What Do They Do? Joints are where two bones meet. They make the skeleton flexible — without them, movement would be impossible. Joints allow our bodies to move in many ways.
How muscles attach to bones?
Skeletal muscles are attached to the skeleton by tough connective tissues called tendons(see Figure above). Many skeletal muscles are attached to the ends of bones that meet at a joint. The muscles span the joint and connect the bones. When the muscles contract, they pull on the bones, causing them to move.
What is the function of Bursa?
Tendons, ligaments, muscles, and skin must glide over bones during joint movement. Tiny, slippery sacs of fluid called bursae facilitate this gliding motion by providing a thin cushion and reducing friction between the surfaces.
Is the brain a muscle?
The brain itself is a not a muscle. It contains blood vessels and nerves, including neurons and glial cells.
Is heart a muscle?
Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly. Your heart is a muscle, and its job is to pump blood throughout your circulatory system.

Are muscles excitable or irritable?
Characteristics of muscle
– Muscles are excitable or irritable. This means that they are capable of receiving and responding to a stimulus.
What is tone in muscle?
Muscle tone is the amount of tension (or resistance to movement) in muscles. … Changes in muscle tone are what enable us to move. Muscle tone also contributes to the control, speed and amount of movement we can achieve. Low muscle tone is used to describe muscles that are floppy, which is also known as hypotonia.
What are the 5 types of muscle contractions?

---|---|---|
Concentric | Shortening (+D) | Acceleration |
Isometric | No change (0 D) | Fixation |
Eccentric | Lengthening (−D) | Deceleration |
What does excitable muscle mean?
Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched or extended. Elasticity is the ability to a muscle to return to its original length when relaxed.
What is muscle elasticity?
Tissue elasticity is the ability to stretch a muscle to reach its full range of movement without restriction.

Why do muscles need oxygen?
Cellular respiration is the process in which your muscles use oxygen to produce ATP energy. … Whether you’re exercising or not, the oxygen in your body is used to break down glucose and create the fuel for your muscles called ATP.
