List 5 functions of the skeletal system
S,S,B,P,M
- Support
- Storage
- Blood Cell Production
- Protect
- Movement
One function of the skeletal system is to store minerals such as calcium; this helps maintain the blood_____________
Levels
The process of blood cell formation in the bones is called __________________
Hematopoiesis
The organic substance of bone gives it a degree of ______________
Flexibility
Blood vessels that nourish the osteocytes or bone cells travel to the area through the ________________
Canaliculi
The wrist and ankle are cubelike in shape; they also may be classified as _________bones
Short
The bone that forms part of the nasal septum is called_________________
Perpendicular Plate
Immovable Joint
Suture of Skull
Movable Joint
Diarthrosis
Fibrous bands that bind joints together
Ligaments
Partially Movable Joint
Amphiarthrosis
Lining the Articular Cartilage
Synovial Membrane

Radius/Ulna
Fibrous Cord Connects Muscle to Bone
Tendons
Elastic Material Between Vertebrae
Disk
An inflannation of the clefts in connective tissue between muscle, tendons, and ligaments is called

Whiplash
An injury to the joint in which the ligaments are torn from the attachments to the bone is called a
dislocation
fracture
sprain
strain
Dislocation
A characteristic shared with the nerve cells; the ability to respond to a stimulus
Excitability
This structure contains membranes fused at places called intercalated disks; a communication system at the fused area will not permit the cells to independently_____________
Contract
Muscles only pull and never push; they are attached to the bones of the skeleton by nonelastic cords called
Tendons
Muscles that open and close to control the passage of substances
Sphincter Muscles
The part of the muscle attached to the movable part of the bone; it is the most movable during a contraction

Peroneus
Muscles that produce movement in a single direction are
antagonists
prime movers
obliques
synergists
Antagonists
Muscles are named in a variety of ways; the muscles on the side of the head are named according to their
action location
location of origin
size
Location
The group of the muscles that make up the hamstrings are
Semitendinosus, biceps femoris and semimembranous
The characteristic of a muscle to be stretched is known as
contractility
