1

What are the 3 functions of the skeletal system?

Framework > base to which muscles attach , help movement
Protection > protecting vital organs
Storage

2

What does the skeleton do?

Protects: Skull, ribs, brain , spinal cord
Is the base for attachment and helps muscle movement

3

What is the function of the long & short bones?

Act as a lever or to transfer forces

4

What is the function of flat bones?

Protect vital organs

5

What bones are in the appendicular system?

Shoulders, arms, hips, legs

6

What is the location and role of the clavicle?

Long bone
Provides attachment between shoulder girdle and vertebral column
Greater mobility to shoulder during movement

7

What is the scapula and its role?

Large triangular flat bone
Allows arm to attach to trunk

8

Where is the humerus located and what is its role ?

Long bone in upper limb
Joins shoulder and elbow
Move in many directions & rotates the joint

9

What is the longer bone on the forearm ; and which finger side of the forearm is it found?

Ulna

10

What bone works with the ulna in the arm?

( Radius ) Long bone in upper limb; forearm
Works with Ulna to provide structure and allows it to rotate

11

What are the bones of the wrist and fingers and what are their roles?

Carpals
Metacarpals
Phalanges
Role: Provide structure to the hand allowing it to perform fine motor movements.

12

Where does the pelvic girdle attach to & what is it's purpose?

Attachment for lower limbs and muscles
Provides base for necessary support of weigh for the upper body

13

Where is the femur located & what is it's role?

Located on the upper leg, covered by large muscles that enable movement

14

What is the bone used for protection of the kneecap

Kneecap

15


Which bone is the fibula and what is it's role

Works with tibia to support and stabilise lower leg joint & rotation of the knee

16

What are the bones of the ankles & which are short / long + what is their role

Tarsals, Metatarsals & Phalanges

T- short M & P - long

Provide structure that enables movements

17

What are fibrous joints ?
Give an example

Immovable joints that occur where no movement is possible.

E.g cranium which are fused lines called sutures

18

What are cartilaginous joints?
Give an example

Slightly movable joints that permit limited movement
E.g Vertebral column- fibrous cartilage between discs

19

What are synovial joints
Provide an example

Freely movable joints that allow maximal movement

E.g Ball and socket in shoulders
Hinge in elbow

20

What is the flexion action & what does it do ?

Decreases the angle between the bones at joint.

21

What is the extension action & what does it do ?

Increases the angle between the bones at the joint

22

What is the dorsi flexion action and what does it do ?

Pulls the top of the foot towards the tibia

23

What is the plantar flexion action & what does it do ?

Extension of the ankle,moves the top of the foot from the tibia

24

What is the abduction action & what does it do ?

Movement of a body part away from the midline of the body

25

What is the adduction action & what does it do ?

Movement of a body part towards the midline of the body

26

What is the rotation action & what does it do ?

Moving body part around on its long axis

27

What is the supination action & what does it do ?

Rotation of hand to face palm upwards

28

What is the pronation action & what does it do ?

Movement of the hand and forearm to face the palm downwards

29

What is the eversion action & what does it do ?

Rotation of foot to make sole of foot face outwards

30

What is the inversion action & what does it do ?

Rotation of foot to make sole of foot face inwards
