Work in opposite directions
What is the prime mover muscle
The major muscle
Muscles with stabilising actions are
Fixators
Name two examples of fixator muscles
At hand and wrist
Muscle fibre is made of many
Myofibrils
Muscles are collections of
Muscle fibres
Striated muscle is found in the: Cardiac sphincter Diaphragm Walls of bronchioles Blood vessels
Diaphragm
Clinical testing of reflex arcs can:
Involve voluntary movements
Only be carried out if the patient is conscious
Help identify the site or level if lesion
Test the integrity of an autonomic nerve
Help identify the site or level of lesion
Which of the following is not involved in the contraction cycle of muscle: Myosin Actin Calmodulin Troponin
Calmodulin
Skeletal muscle: Contracts spontaneously in the absence of innervation Is under voluntary control Contains pacemaker cells Is caused to relax by hormones
Is under voluntary control
Red muscle is … muscle
Endurance
Pale muscle is … muscle, it requires more force
Active
A single muscle cell = a
Muscle fibre
Name three types of muscle fibre
Type I
Type IIA
Type IIB
Type I muscle is slowly contracting, low force and high endurance who would use it
Marathon runner
