Answer 1

Most stationary, proximal attachment

Question 2

Insertion

Answer 2

Mobile and usually distal attachment

Question 3

Answer 3

Fascicles

Question 4

What does muscles organisation affect ?

Answer 4

Power
Range
Speed
Muscles movement

Question 5

The patterns of fascicles organisations and their relationship to the tendon skeletal muscles can be classified as

Answer 5

Parallel
Convergent
Pennate
Circular

Question 6

Parallel muscles

Answer 6

Fascicles parallel to muscle long axis

Question 7

Convergent muscles

Answer 7

Fascicles converge at a single tendon

Question 8

Pennate muscles

Answer 8

Fascicles arise from tendon
3 patterns

Question 9

Circular muscles

Answer 9

Fascicles in circle around an opening

Question 10

Most muscles …

Answer 10

Originate and insert onto skeleton

Question 11

Belly

Answer 11

Between origin and insertion

Question 12

Joint (muscle wise )

Answer 12

Muscles Usually crosses it

Question 13

Descriptive names for skeletal muscles

Answer 13

Location in the body
Origin and insertion
Fascicle organisation
Relative position
Structural characteristics

Question 14

Muscle insertions

Answer 14

-muscles work in groups to maximize efficiency

• Small muscles reach maximum tension first followed by larger primary muscles

Question 15

Agonist

Answer 15

plays a major role in movement
its the prime mover

Question 16

Antagonist

Answer 16

opposes movement produced by a particular agonist

Question 17

Synergist

Answer 17

smaller muscle, assist a larger agonist

Question 18

Function of synergist

Answer 18

Help start motion and stabilize origin of motion

Question 19

Relationship between agonist and antagonist

Answer 19

they work in pairs

Question 20

True or false:
There is usually a joint between origin and insertion

Answer 20

True

Question 21

during the action where does the insertion go

Answer 21

towards the origin
