Q

What are the differences between pelvic and pectoral girdle?

A

Pelvic is stronger and designed for stability and weight bearing and has less mobility. Pectoral has less stability but more mobility and a great range of motion

Q

What is the fuction of the cervical vertebrae?

A
  • curve develops to support head
17
Q

What are the characteristics of Cancellous bone?

A

Light and spongy, shock absorbing, resists and channels forces from multiple directions

18
Q

What class of bone is:

  • function is usually for muscle attatchments
  • function is also for protection
  • they are thin plates of compact bone (some cancellous inside)
A

Flat bone

19
Q

What is the function of the Thoracic vertebrae?

A
  • primary curve provides space for thoracic organs
20
Q

What are the characteristics of long bones?

A
  • longer than wide
  • composed of wider epiphysis + longer, narrower diaphysis
  • act as levers
  • mostly are limb bones
21
Q

What section of the vertebral column has a primary curve that provides space for thoracic organs?

A

Thoracic

  • mostly are limb bones
A

Long bone

23
Q

What are the overall main functions of the vertebral column?

A
  • keeps trunk upright

  • Supports head
24
Q

What are the characteristics of Irregular bones?

A
  • anything that doesn’t fit another category
  • various shapes and functions

25
Q

What are the characteristics of flat bones?

A
  • function is usually for muscle attatchments
  • function is also for protection
  • they are thin plates of compact bone (some cancellous inside)
  • e.g. scapula and skull
26
Q

What is the function of the sacral and coccygeal bones?

A

provides space for pelvic organs

27
Q

What are the characteristics of compact bone

A

strong and good at transmitting force in one direction
