Muscular System
- Functions of Muscles
- Movement
- muscles contract and relax
so we can move our limbs
- muscles contract and relax
so we can move our limbs
- Shape
- maintains good posture
- maintains good posture
- Protection
- keep our abdominal
muscles in place
- keep our abdominal
muscles in place
- Circulations
- helps circulate our blood
- helps circulate our blood
- Temperature
- muscles generate
body heat when they
contract
- muscles generate
body heat when they
contract
- Movement
- Types of muscles
- CARDIAC
- Contracts and relaxes
to pump blood
- The cardiac
muscles never get
tired
- Works without
conscious effort
- Contracts and relaxes
to pump blood
- SMOOTH MUSCLE
- Work without
conscious
effort
- involuntary
muscles
- involuntary
muscles
- provide nutrients and
remove waste
- around organs such as
intestines
- Work without
conscious
effort
- SKELETAL
- attached to the skeleton
- Voluntary
- make our bodies move
- will improve our
performance if we train
them
- attached to the skeleton
- CARDIAC
- Muscles and movement
- movement at a joint is
caused by muscles
contracting to pull on the
tendons
- movement is
produced by
muscles working in
pairs
- agonist is the prime
mover - e.g. bicep
- attached by tendons to the
shoulder - when it contracts
the forearm is raised at the elbow
- attached by tendons to the
shoulder - when it contracts
the forearm is raised at the elbow
- antagonist- e.g. tricep is the
muscle that relaxes to
allow movement
- the tricep contracts it pulls the
forearm down and extends the elbow
- the tricep contracts it pulls the
forearm down and extends the elbow
- agonist is the prime
mover - e.g. bicep
- The origin - where the
muscle joins to the
stationary bones
- the insertion- where the muscle
joins a moving bone
- when muscles contract the
insertion moved towards the
origin
- the insertion- where the muscle
joins a moving bone
- TYPES OF MOVEMENT
- Flexion
- decreasing the
angle at a joint
- elbox joint
- bicep curl
- elbox joint
- decreasing the
angle at a joint
- Extension
- increasing the angle
at a joint
- elbow joint
- tricep extension
- elbow joint
- increasing the angle
at a joint
- abduction
- taking a limb away
from the midline
of the body
- outward phase of
breaststroke arms
- shoulder joint
- outward phase of
breaststroke arms
- taking a limb away
from the midline
of the body
- Adduction
- moving a limb back
towards the midline
- inward phase of
breastroke arms
- shoulder joint
- inward phase of
breastroke arms
- moving a limb back
towards the midline
- Rotation
- moving a body part
around a longitudinal
axis
- cricket bowl
- shoulder joint
- cricket bowl
- moving a body part
around a longitudinal
axis
- Flexion
- movement at a joint is
caused by muscles
contracting to pull on the
tendons
