Q

what are the 4 types of muscle contractions

A

isotonic, isometric, eccentric, concentric

18
Q

how do the muscles create movement

A

the tendons pull on bones

19
Q

what are 3 types of muscles

A

antagonist, agonist, fixator

20
Q

what is the agonist

A

the muscle directly responsible for movemnet

21
Q

What is a motor unit made of

A

a group of fibres and its neuron

22
Q

what is a neuron composed of

A

the axon, the myelin sheath, dendrites

23
Q

what is an electromechanical process

A

the transmission of a neural message

24
Q

When does a neurone have resting potential

A

when it isn’t conducting an impulse

25
When does action potential occur
when a sufficient number of sodium ions have diffused into the neuron
26
what happens to the axon when the sodium ions diffuse
it is depolarized
27
what are the three types of muscle fibres
slow twitch, fast glycolytic, fast oxidative glycolytic
28
which musce fibre has the highest anaerobic capacity
Fast glycolytic
29
What agonistic pair can be found at the wrist
wrist flexors, wrist extensors
30
what range of movement is available at the elbow
flexion, extension
31
what muscle is responsible for flexion at the elbow
bicep brachii
32
What is the agonist for adduction at the shoulder
latissimus dorsi
33
what is the agonist for flexion at the hip
illiopsoas
34
what is the antagonist for flexion at the hip
gluteus maximus
35
what muscles are a part of the hamstring group
bicep femoris, semitendonosus, semimembranosus
36
what is the agonist for flexion at the knee
the hamstring group
37
what muscles are a part of the adductor group
adductor longus, adductor brevis, adductor magnus
38
what muscles are found at the ankle joint
gastocnemius, soleus, tibialis anterior
39
what movement can be found at the ankle
dorsiflexion, plantar flexion
40
what is the agonist for dorsiflexion
tibialis anterior
