The Skeletal System Flashcards
A type of skeleton found usually in vertebrates
Endoskeleton
Is found in soft bodied animals and relies on water pressure to move them
Hydrostatic skeleton
Enumerate the types of skeletal systems
-Endoskeleton
-Exoskeleton
-Hydrostatic skeleton
A type of skeleton that acts as a protective covering of the hardened material outside the body and is primarily used for protection
Exoskeleton
is the muscle that does not move
Origin
What are the functions of the skeletal system
-Acts as the bodies framework
-works w muscular system to aid in movement
- provides structure and protection
- storage site for minerals
- site for hematopoiesis
the muscle that is moved
Insertion
Types of bones
Long Bones
Flat Bones
Short bones
Irregular bones
Are longer than wide bones
long bones
What does a long bone consist of
Yellow marrow- fatty connective tissue
Red Marrow- Blood cell production
Are boxed bones (name the examples as well)
Short bones
-Carpals
-Capitates
A type of bone with a broad surface (name the examples as well)
Flat bones
-sternum
-ribs
Are bones that do not fit into any other category.
Irregular bones
Name the divisions of the skeletal system
Axial skeleton
Appendicular skeleton
Forms the axis of the body
Axial Skeleton
This includes: Skull, vertebral column, ribs, sternum
Includes the bones of the upper and lower limbs
Appendicular Skeleton
This Includes:
Pectorial girdle
Pelvic Girdle
Forelimb
Hindlimb
Enumerate the types of joints
Immovable or fibrous joints
slightly movable joints
Freely movable joints
Pivot joint
gliding joint
Hinge joints
Ball and Socket Joint
are where flat bones meet.
Gliding Joint
allows the rotation of one joint based on where it is attached.
Pivot joint
allow the motion of one plane of axis.
Hinge joints
allows a wide range of motion and rotation.
Ball and socket joint
are found between flat bones.
Immovable or fibrous joints
Are found between each of the vertebrae
Slightly movable joints
These joints are the most important in movement
Freely movable joints
