2. INTRODUCTION
DEFINITION: This is an organ system
involves muscles, bones and cardiac
muscles.
FUNCTIONS OF MUSCLES
Movement
Shape/posture
Protection
Circulation of blood through out the body
Thermostatic action
3. There are over 600 skeletol muscles in the
body
Among them 150 present in head and neck
The muscular system in vertebrates is
controlled through the nervous system.
4. TYPES MUSCLES
SKELETAL MUSCLES: it is also known as
voluntary muscles
SMOOTH MUSCLES:involuntary muscles
CARDIAC MUSCLES
Muscles provide strength, balance, posture,
movement and heat for the body to keep
warm.
5. SKELETAL MUSCLES: these are voluntary
control
Examples like everyday actions such as
walking, running, and jumping.
Major skeletal muscles are
deltoid,biceps,triceps,trapezius etc…
6. SMOOTH MUSCLES: these are involuntary
muscles.
this type of muscles work automatically
Example: muscles of digestive system
muscles of respiratory system, muscles of eye
and cardiac system.
7. CARDIAC MUSCLE:it is a special type of
involuntary muscle
It is only found in heart
It contracts regularly,continously without rest.
It works automatically but under the control of
nervous system.
8. TYPES OF MUSCULAR
CONTRCTION
ISOTONIC AND CONCENTRIC
ISOTONIC AND ECCENTRIC
ISOMETRIC
ISOTONIC AND CONCENTRIC: our
muscles shorten as they contract.
Example: exercise
9. ISOTONIC AND ECCENTRIC
muscles lengthen as they contract in
tension
Examples: polymetric exercise.
ISOMETRIC:muscles stay the same length as
they contract
Example: shoulder muscles
10. Muscles can work as
Flexors
Extensors
Prime movers
Antagonists
Fixators
Synergists
