29
Q

What is the order is the vertebrae?

A

30
Q

What are the 4 types of bones?

A

Long bones
Short bones
Irregular bones
Flat bones

31
Q

Function of long bones:

A

Generate movement(leavers)/strength

32
Q

Function of short bones

A

Weight bearing

Shock absorption

33
Q

What is the Function of irregular bones?

A

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
34
Q

Flat bones function

A

Protection of vital organs

A good surface area for muscles to attach to

35
Q

Some people call it the tail bone.

A

Coccyx

36
Q

What are long bones?

Specification
In sport
Examples

A

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

37
Q

What are short bones?

Specification
In sport
Examples

A

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.

38
Q

What are flat bones?

Specification
In sport
Examples

A

They protect organs and offer a good serface area to attac to.

39
Q

What are joints?

A

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
40
Q

What are Irregular bones?

A

Have odd shape and vary in function

E.g vertebrae which protects the spinal cloumn

-Sacrum which has a lot of attachment points

41
Q

Examples of long bones:

A

Femur
Tibia
Fibia
Phalanges

42
Q

Example of short bones

A

Carpals

Tarsals

43
Q

Examples of flat bones

A
  • clavicle
  • scapula
  • cranium
44
Q

Example of irregular bones?

A
  • vertebrae

- sacrum

45
Q

How many bones are in the spinal column?

A

33

46
Q

What is ossification?

A

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.
