Musclar System

Question 1

What on is the function of strained muscles of the Skelton

Answer 1

Movement of bones from and joints
Maintaining posture
Heat production

Question 2

What are three type of muscles contractions

Answer 2

CONCENTRIC - contracts and shortens ( climbing stairs )

Eccentric - contracts but lengthens due to the load ( carrying a load )

Isometric- contracts but remains the same length due to the load ( in tug of war)

Question 3

What are two types of muscle types

Answer 3

Agonists (prime movers) are the main activating muscles,

Antagonists work as a pair with and in opposition to agonists. One relaxes as the other contracts to create movement.

Question 4

What are the other two types of muscle types

Answer 4

Synergists - work to assist agnostics or antagonist muscles
Fixators - are muscles which stabilise bones , bones enabling agonist to work effectively

Question 5

What is orgin and intersection ( MUSCLES

Answer 5

Orgin is - the attachment of muscle closest to the centre of the body.
Insertion - the attachment of muscle furthest away from the centre body

Question 6

What are the three muscle attachments

Answer 6

Tendons
Ligaments
Fasciae

Question 7

Tendons : muscle statements

Answer 7

Tendons are strong fibrous bands which link muscle to bones and transmits the contractile force of the the muscle to the bone , creating movements. The tendons are inflexible and do not contract and stretch

Question 8

Ligaments : muscle attachment

Answer 8

Ligaments are strong fibrous elastic structure which stabilises joints by joining bone to bones. Ligaments are pliable enough to allow movement of a joint but prevent overstretching

Question 9

Fasciae

Answer 9

Consist of fibrous connective tissue. A fascia separates different muscles, protecting them while allowing them to move alongside one another .egz facial muscles can move whereas skull cannot move

Question 10

Muscle dystrophy

Answer 10

Is a genetic condition caused by change in muscle fibres bc of lack of protein, which could impact muscle function causing muscle weakness
Cardiovascular
Irregular heart beat
- the heart is a muscle, the walls of heart become thinner and less likely to pump blood around body
Unable to contract ( irregular heart rest and heart faliure )
Lungs
Shallow breathing
- the muscles in lung suhh as diagrapm and intercostal muscles damage means difficulty breathing
Increase mucus production - means more lung infections ( PNEUMONIA)
And persistent coughing
Digestive problem -
Weight loss
osephgusus and abdominal problems causes malnutrition and weight loss
