What are the 4 movements of the muscular system?
The role of skeletal muscle
When discussing the skeletal system we described the movements that can occur at joints, namely;
flexion, extension, abduction, inversion etc
. Skeletal muscles produce these movements by pulling bones in different directions.
What are the main functions of the muscles?
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 are the four major functional characteristics of muscle tissue?
Muscle has four functional characteristics:
contractility, excitability, extensibility, and clasticity
. elasticity 2. The capacity to respond to a stimulus.

What are the 3 types of muscles and their functions?
- Skeletal muscle – the specialised tissue that is attached to bones and allows movement. …
- Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. …
- Cardiac muscle – the muscle specific to the heart.
Why is muscle important in the body?
Muscle is also very important to everyone because
we need our muscles to survive
. The heart is the strongest muscle in our body and is always looking to get stronger. Muscles enable us to be active and exercise. Our strength comes for our muscles and how much they are used.
What are the muscle actions?

- Elevation and depression.
- Flexion and extension.
- Inversion and eversion.
- Plantarflexion and dorsiflexion.
- Pronation & supination.
- Protraction and retraction.
What are the 4 characteristics of muscles?
- excitability.
- contractility.
- extensibility – they can be stretched.
- elasticity – they return to normal length after stretching.
What are the properties and functions of muscles?
- Contractility is the ability of muscle cells to forcefully shorten. …
- Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone.
What are the 4 properties of skeletal muscle?
All muscle cells share several properties:
contractility, excitability, extensibility, and elasticity
: Contractility is the ability of muscle cells to forcefully shorten.

What are the functions of muscles for kids?
Muscles
provide the tug on the bones needed to bend, straighten, and support joints
. Muscles can pull on bones, but they can’t push them back to their original position, so the muscles work in pairs of flexors and extensors. The extensor muscle relaxes and stretches as the flexor muscle contracts to bend the joint.
