SKELETAL SYSTEM Flashcards
The skeletal and muscular systems are very closely linked and are often referred to as the
musculo-skeletal system
provides the framework that allows movement to take place
skeleton
provide the energy to pull our bones and joints into the correct positions needed for different types of physical activity
skeletal muscles
provides the body with an overall structural framework
skeletal system
two divisions of the skeletal system
axial skeleton and appendicular skeleton
found around the VERTICAL AXIS of the body
Axial Skeleton
the axial skeleton includes
skull, vertebral column, sternum (breastbone), and ribs.
consists of the UPPER AND LOWER LIMBS and the girdles that attach the limbs to the axial skeleton.
Appendicular Skeleton
The pectoral girdle (or shoulder) is associated with the
upper limbs (arms)
the pelvic girdle (or pelvis) is associated with the
lower limbs (legs)
bones that are arranged in a manner that allows people to PERFORM BASIC FUNCTIONS such as locomotion, gathering food and other objects, and using tools.
appendicular skeletal system
The bones of the appendicular skeletal system are also involved in
protection, mineral storage, and production of blood cells and platelets
The BONY FRAMEWORK upon which the rest of the body is built.
skeleton
It provides ATTACHMENTS for the muscular system and carries and protects the cardiovascular and respiratory systems.
Skeleton
This ATTACHES TO and MOVES the skeleton.
skeletal muscle
It is often termed STRIATED MUSCLE because it has OBVIOUS STRIPES on it caused by the long muscle fibers of which it is composed.
Skeletal muscle
It is also called VOLUNTARY MUSCLE because it is the only type of muscle under our conscious control.
skeletal muscle
A place on the body where TWO OR MORE BONES MEET
joint
The average human adult has
206 bones
Axial Skeleton
skull
thoracic girdle
vertebral column
appendicular skeleton
shoulder girdle and upper limbs
pelvic girdle and lower limbs
A baby’s body has about
300 bones at birth
Some of a baby’s bones are made entirely of a special material called
cartilage
The bones of the UPPER AND LOWER LIMBS and their GIRDLES that join to the axial skeleton
Appendicular skeleton
Appendicular Skeleton includes bones of
Pectoral girdle
Upper extremity
Pelvic girdle
Lower extremity
This forms the LONG AXIS of the body and includes the bones of the skull, spine and rib cage.
Axial skeleton
Axial Skeleton Includes bones in
Head
Neck
Spine
Chest
Trunk
The CLAVICLE (collar bone), SCAPULA (shoulder blade) and PELVIS belong to the
appendicular skeleton
It is a _________ to link them to the axial skeleton.
common error
A TOUGH BAND of fibrous, slightly elastic connective tissue that ATTACHES ONE BONE TO ANOTHER. It BINDS the ends of bones together to PREVENT DISLOCATION
Ligament
A VERY STRONG CONNECTIVE TISSUE that attaches skeletal muscle to bone
Tendon
