25
What are diaphram muscles?
Muscles that attach to bone on either side of the midline of the body
26
What does the diaphram separate?
The thorax from he abdomen
27
On contraction of the diaphram muscle what happens to the air capacity for the lungs?
It increases
28
When the diaphram descends what is the effect?
Increase in thoracic volume
29
What effect do the anterior fibres have on the shoulder joint?
Flexion
30
What effect do the midline fibres have on the shoulder joint?
Abduction
31
What effect do the posterior fibres have on the shoulder joint?
Extension
32
What is the effect of combining the anterior, posterior and midline fibres on the shoulder joint?
Circumduction
33
What are agonist muscles
The muscles that are the prime movers
34
What are the antagonist muscles?
The muscles that follow the movements of the prime movers
35
In flexion of the elbow what is the agonist?
Biceps
36
In the flexion of the elbow what is the antagonist?
Tricep
37
In the extension of the elbow what is the agonist?
Tricep
38
In the extension of the elbow what is the antagonist?
Bicep
39
What are the muscles of the forearm divided into?
The anterior and posterior part
40
Are muscles of the same compartment usually supplied by the same nerve?
Yes
41
Why is the rotator cuff at the shoulder joint necessary?
It is the most susceptible to dislocation
42
From what vertebral levels are the arm and forearm supplied by?
C5-T1
43
What are the groups of nerves supplying the arm known as?
Brachial plexus
44

L1-S4
46
To what degree do the oblique muscles lie to each other?
90 degrees
47
Why are the muscles flat and thin on the anterior chest wall?
So the structures reduce pressure on the lungs
48

Inferior
49
What is the opposite to medial?
Lateral
50
What is the opposite to major?
Minor
51
What is the opposite to anterior?
Posterior
52

Round
53
Where is the teres major found?
In the shoulder
54
What shape is the deltoid muscle?

57
What innervates the limb muscles?
Limb nerve plexuses
58
What is CT good for looking at?

59
What is MRI good for looking at?
Tissue
60
What ensure simultaneous contraction in cardiac muscle?
Intercalated discs
61
How are the nucleus in smooth muscle?

Segmentally
74
What dermatome is at L1?
The skin over the groin
75
Does the diaphram descend or ascend on contraction?
Descends
76
What do synergists do?
Help perform the same action as the agonist muscle
77
What is a synergist to the biceps?
Brachioradialis and brachioradialis
78
What does rectus mean?
Straight
79
What is the function of the aponeurosis?
To absorb energy for muscular contraction
80
