– Muscles are excitable or irritable. This means that
they are capable of receiving and responding to a stimulus
.
What is the difference between irritability and contractility?
IRRITABILITY [the ability to RESPOND to a stimulus] Muscles are routinely stimulated by signals from the nerves that supply them. The response to all forms of stimulus is muscle contraction. CONTRACTILITY [the ability to contact or
shorten
] this is unique to muscle tissue.
What is irritability in muscles?
Muscle Properties Irritability – A muscle irritability refers
to the ability of the muscle to respond to a stimulus
.
What is extensibility in muscle?
Muscle extensibility:
ability of a muscle to extend to a predetermined endpoint
.
Are muscles Contractible?
Contractible –
Once they have received stimulation, the muscle is capable of actively shortening (contracting)
. 3. Extensible – With the application of force, muscle can be stretched without damage.
What are the 5 major properties of muscular system?
- Excitable or Irritable.
- Contractible.
- Extensible.
- Elasticity.
- Adaptability.
What do you call the most irritable tissue in the body?
Characteristics of
muscle tissue
Irritability. (excitability) muscles receive and respond to stimulation.
What are the 5 types of muscle movements?
- Abduction.
- Adduction.
- Flexion.
- Hyperflexion.
- Extension.
- Hyperextension.
- Rotation.
- Internal rotation.
What are the three major types of muscles?
- 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.
What is the function of muscular tissue in our body?
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.
What exercise helps the extensibility of your muscles?
1)
Dynamic Stretching
Dynamic stretching techniques allow you to target muscle groups and ligaments which in turn improve muscle elasticity.
What are the 4 properties of muscles?
- excitability.
- contractility.
- extensibility – they can be stretched.
- elasticity – they return to normal length after stretching.
What is the major function of 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 attaches muscles to bone?
Tendons
: Tendons connect muscles to bones. Made of fibrous tissue and collagen, tendons are tough but not very stretchy.
What are 6 major types of muscles?
- Comparison of types.
- Skeletal muscle.
- Smooth muscle.
- Cardiac muscle.
- Skeletal muscle.
- Smooth muscle.
- Cardiac muscle.
What part of the muscle moves the least during the contraction?
| A B | origin attached to a fixed structure or bone; moves least during contraction | insertion attached to a movable part or bone and moves most during contraction | belly central body of the muscle | prime mover muscles that produce movement in a single direction |
