Muscular system
SEE YOUR BODY FROM THE INSIDE
the human muscular system consists of 3 types of muscles
The cardiac muscleThe smooth muscle The skeletal muscle
the cardiac muscle
Heart
the cardiac muscle is:1. involuntary 2.responsible for the rythmic contractions of the heart
SMOOTH MUSCLE
smooth muscles are:
1. Involuntary 2. They are found in the the walls of blood vessels, intestines, urinary bladder and the stomach. 3. The muscular walls of the intestines contract to push food through the body
the skeletal muscle
skeletal muscle
1.Voluntary2. Responsible for posture, balance and movement 3. About 600
Muscles are made up of bundles of fibres (pg159)
major muscles of the body
Pg 160
Posterior
gluteus, hamstring, calves,triceps...
Anterior
pectoralis, quadriceps, abdominals...
effects of exercises onthe musculAr system
EXERCISES HAS BOTH LONG TERM EFFECTS AND SHORT TERM EFFETCS ON MUSCLES. IT DEPENDS ON THE DURATION AND INTENSITY OF THE WORKOUT.

Better postureIncreasees muscular endurance Muscles becomes stronger Hypertrophy Greter volume of blood supply to the muscles.
Muscle fatigueMuscle soreness Increase in temperature of muscles.
