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
