MUSCLE PROPERTIES

• Irritability - stimulation
• Conductivity - wave
• Contractility - tension
• Distensibility - stretching
• Elasticity - recoil ability

3
QUALITIES OF MUSCLES

• Flexibility - ROM
• Strength - tension
• Power - Fv
• Endurance - repeated/sustained

4
Skeletal Muscle Anatomy

• Attachment
• Origin
• Insertion

5
FIBER ARRANGEMENTS

• Fusiform - longitudinal
• Pennate - oblique angle

6
LAN

• Location
• Angle
• Number

7
ACTIVE INSUFFICIENCY

• Biarticulate Muscle
• Contraction Limitation
• Figure 2.3 page 57 - Left Hamstrings

8
PASSIVE INSUFFICIENCY

• Biarticulate Muscle
• Stretching Limitation
• Figure 2.3 page 57 - Right Hamstrings

9
MUSCLE ARTICULATION

• Uniarticulate
• Biarticulatee.g knee/hip joints (hams,quads)
• Multiarticulatee.g. elbow/radioulnar/wrist/hand
  joints(flexor digitorum profundus)

10
RECIPROCAL INNERVATION

• Agonist
• Antagonist

11
MUSCULAR TENSION TYPES

• Static - isometric
• Dynamic
• Concentric
• Eccentric

12
SYNERGY

• Working Together - two agonists work together to
  move segment
• True- agonist moves, antagonist stabilizes
• Helping- both agonist antagonist work together
  to move segment

13
Question 15 - page 60

• Articulation/joint
• Motion name
• Motive Force
• Resistive Force
• Contraction Type
• Stabilized Area

14
Figure 2.5 C - page 61

• Articulation - knee
• Motion - extension flexion
• Motive F - muscle g
• Resistive F - g muscle
• Contraction - concentric eccentric
• Stabilized - trunk thigh
