DIFFERENT ORGAN SYSTEMS
OSSEOUS SYSTEM (SKELETON)..OUR moden building and machines appear as engineering marvels however many of the so called ingenious devices seen in bridges building and machines are also observed in the human skeleton the primary purpose of skeleton is to support the body it is strong enough to resist great pressure yet flexible enough to absorb a certain amount of shock without shattering it also permits necessary movements
the skeleton is the framework of bones which are organized to form distinct parts such as skull vertebral column thoracic cage upper and lower extremity bones
articular system the articular system is joining various bones at their ends or edges by means of cartilages membranes and ligaments the joints give the movements by co ordinated contraction of groups of muscles which are controlled by nerves
muscular system there are three types of muscles in the body 1.skeletal 2.visceral and 3.cardiac their name suggest their location skeletal muscles are usually attached to bones visceral muscles are found in the visceral organs such of stomach intestine etc and the heart is made up of cardiac muscles skeletal muscles are voluntary while cardiac and visceral muscles are involuntary in nature involuntary and voluntary muscles are controlled by autonomic and central nervous system respectively skeletal muscles work with bones ligaments and cartilages to produce movement at the body joints
