2. Angular motion
3. General motion
What are the three types of muscles
1. Cardiac
2. Skeletal

What are the four functions of muscles?
1. Posture
2. Movement
3. Stabilise the joints
4. Bodily Functions
What movements do the lower limbs perform during a side stepping action?
Abduction and adduction
Circumduction
Describe linear motion in 3 points.
1. Movement in a straight line
2. All parts travel in the same direction
3. All parts travel at the same speed
4. All parts travel at the same time
What is unique about smooth muscles?
Smooth muscles are non-striated, assist with bodily functions, and are found on the walls of hollow internal structures.
They are fatigue resistant and have involuntary contractions.
Explain how muscles produce movement
During the execution phase of a soccer penalty shot, what movement occurs at the knee?
Bonus mark: what muscle is contracting
Bonus mark: quadricep
List four muscles involved with a netball chest pass?
Pectoralis, biceps, triceps, deltoids
Describe angular motion in 3 points
1. Movement around a joint or axis
2. All parts move in the same direction
3. All parts move at the same time
4. Not all parts will travel the same distance
What are the key features of skeletal muscles
Striated. Attach to the skeleton via tendons. Cause movement. Have strong voluntary contractions. Have two distinct fibres (fast twitch and slow twitch).
Explain how muscles assist maintaining posture
As a ballerina points their toes to pirouette, what muscles is she using?
Bonus question: what is the movement?
Soleus and gastrocnemius
Bonus answer: plantar flexion
In an ultimate frisbee backhand pass, list three muscles that contract during the execution phase
Triceps, latissimus dorsi, deltoids
In a volleyball float serve, what is the motion of the ball
Curvilinear
Where are they found
Cardiac muscle is found in the heart.
They are striated, involuntary contractions, and fatigue resistance.
Explain the linear and angular motion involved with a figure skater skating across the ice.
What type of motion is this called.
Angular: rotational movement of the legs to propel forward
How do muscles assist bodily functions?
Give an example
Voluntary and involuntary contractions of the muscles assist in bodily functions such as breathing, digestion, pumping the heart and blood around the body, bowel movement.
The continual contractions will keep things moving to keep you alive.
