Soc12 skeletal system Flashcards
What are the five functions of the skeletal system?
- Protection of vital organs
- muscle attachment
- joints for movement
- storing calcium and phosphorus
- red and white blood cell production
What is the bone that protects the brain and covers the head?
Cranium
What is the bone on the upper arm?
Humerus
What is the bone that protect the heart and lung and covers around them?
Ribs
What is the larger bone in the lower leg that sum refer to as the shin?
Tibia
What is the smaller outer of the two lower leg bones that extend from the knee?
Fibula
What is the flat rounded bone (often called ‘knee cap’)
Patella
What is the bone in the upper leg?
Femur
What is the bone that forms the upper jaw?
Maxilla
What js the bone that forms the lower jaw and part of the ‘skull’
Mandible
What is the bone located in the shoulder and know as the ‘shoulder bone’
Scapula
What is the bone that makes up toes and fingers on the hand and foot?
Phalanges
What is the bone that stretches from the elbow to the smallest finger?
Ulna
What is the bone that runs from the elblow to the thumb?
Radius bone
What is the bone that some people call the “collar bone” located above the rib chage and near to the scapula?
Clavicle
What is the bone located in the centeral part of the chest?-it connects to the ribs
Sternum
What is Set of 7 irregular shaped bones in the ankle/foot area?
Tarsals
What is the bones in the mid-foot that is connected to the tarsals and phalanges
Metatarsals
What are the eight smallbones that make up the wrist?
Carpals
What is the bone that is in the middle of the phalanges and carpals in thr hand?
Metacarpals
What is thr bone in the lower part of the torso and is located between the abdomen and legs?
Pelvis
What is the Largest of the three bones that fuse together over tike to form the outer section of the pelvis?
ilium
What is the large bone located at the end of the vertebrae where it forms the back of the pelvis?
Sacrum
What is the lower and back part of the hip bone?
-situated below the ilium
Ischium
What is the upper part of your spine than some call the neck bone
Cervical vertebrae
What is the bone in the second spinal column under the cervical vertebrae?
Thoracic vertebrae
What is the third region of the vertebrae column?
Lumbar vertebrae
What forms the ‘hip bone’?
illum
Ischum
What is the order is the vertebrae?
Cervical(7bones) Theracic(12 bones) Lumbar (5 bones) Sacrum(5 fused bones) Coccyx(4 fused bones)
What are the 4 types of bones?
Long bones
Short bones
Irregular bones
Flat bones
Function of long bones:
Generate movement(leavers)/strength
Function of short bones
Weight bearing
Shock absorption
What is the Function of irregular bones?
Irregular bones have odd shapes and perform a range of functions.
- some have special shapes so they can protect something(eg vertebrae)
- others have attachment points for muscle
Flat bones function
Protection of vital organs
A good surface area for muscles to attach to
Some people call it the tail bone.
Coccyx
What are long bones?
Specification
In sport
Examples
Long bones are longer than they are wide
(Doesn’t have to be big, phalanges(finger bones) count as long bones)
-Long bones have a shaft and two ends
In sport: they are vital to generate movement,strength and speed.
They act as LEVERS. When pulled by diffrent muscles they enable the bone to move.
Examples: phalanges, femur, tibia, fibia
What are short bones?
Specification
In sport
Examples
Same size in length, width and thickness
Examples: carpals,tarsals
Sport: associated with WEIGHT BARING, sock obsorbtion, and spreading load. Play a key role in acrivities like jogging, tennis and dancing.
What are flat bones?
Specification
In sport
Examples
They protect organs and offer a good serface area to attac to.
What are joints?
A place where two or more bones meet,
- important for movement and rotation
- all of them allow movement the extend of the freedom and the movement VARIES from join to joint
What are Irregular bones?
Have odd shape and vary in function
E.g vertebrae which protects the spinal cloumn
-Sacrum which has a lot of attachment points
Examples of long bones:
Femur
Tibia
Fibia
Phalanges
Example of short bones
Carpals
Tarsals
Examples of flat bones
- clavicle
- scapula
- cranium
Example of irregular bones?
- vertebrae
- sacrum
How many bones are in the spinal column?
33
What is ossification?
the natural process of bone formation
the hardening (as of muscular tissue) into a bony substance. 2 : a mass or particle of ossified tissue. 3 : a tendency toward or state of being molded into a rigid, conventional, sterile, or unimaginative condition.
