Movement System

Movement system

Motion is shape from the

reaction in organisms about

stimulation from the environment.

Motion system is motion

combination systematic is consist

to organisms.

Example: walking and dancing

Movement system

Motion system in animal consist of thebone and the muscle.

The bone is the tool passive motion.The bone can be motion because there arethe muscle to movement. The musclecalled the tool active motion because canbe contraction and relaxation

Framework system

Our body is consist from kinds of the bone

with the shape, the size, place, and different

function.

Human body framework to divide for two kinds,

that’s:

1. Axial framework is consist of cranium, columna

vertebralis, costa and sternum

2. Apendicular framework is consist of bracelet

shoulder bone (pectoral bracelet ), component

above the motion which is pelvis bone and

component beneath the motion.

The Function of Framework System

Framework system have some function that’s:

1. To building the body

2. To give the shape for the body

3. To protect the part of the body

4. As a muscle attachment

5. As a place to manufacture red blood cells

and white blood cells that is within he

spinal cord.

The Kinds of Bones is Based from the

Shape

Based on the shape, the bone can be

divided into three kinds, that’s:

1. Bone pipe

2. Bone flat

3. Bone small

1. Bone pipe

Called a bone shape like a pipe because the pipe, which is round, elongate and the center hole. Inside the pipe is consist the bone marrow and fat yellow

Example: arm bone, femur and knuckle bone

2. Bone flat

The shape of bone flat is flat. In bone is consist the red marrow

Example: rib, sternum, scapula, pelvis and brow bone

3. Bone small

The shape of the bone is small and short, so called vertebrate bone. Inside the small bone consist is red marrow.

Example: columnavertebrate, wrist and ankle

connection between the bone (joint or articulation)

The bones making up the framework of

inter-related. Transportation between

the bones to each other is called joint.

The joint can be divided for:

1. Sinartrosis is joint connection between

the bones that one with the other

bones but can not to movement, for

example is inter-bone compiler the

skull

2. Amfiartrosis is the connection between

the bones that one with the other bone

but just can be movement accordance

with limited, for example is inter-bone

rib and sternum

3. Diartrosis is related inter-bone

between the bones that one with other

bone maybe so that the occur bone

movement with more released.

Anomaly of shape the Human Body Framework

The shape of framework from the

human sometimes anomaly experience.

The anomaly can be caused by somes

factor that’s anomaly when born,

because the food, habit of body

position is wrong or because of illness

or because the disease
