A

More complexed shapes

25
What is a joint
Where 2 or more bones come into contact with each other
26
What is a Tendon
A connective tissue that connects muscles to bones
27
What is a ligament
Connects two bones
28
What is Cartilage
Resilient elastic tissue that covers the end of long bones reducing friction
29
What are the three types of joints
Synovial joints, Fibrous joints and Cartilaginous joints
30
Synovial Joint
The most common joint and is most important joint for mobility eg knee
31
Fibrous joints
Connects the edge of 2 bones allowing for no movement eg skull
32
Cartilaginous joints
Allow for little movement and absorb shock eg Pelvis
33
Inferior
Below/further away from head
34
Superior-
Closer to your head
35
Distal
Further away from where limb attached to body
36
Proximal
nearer to where a limb is attached to the body
37
Posterior
anything on the back half of the body
38
Anterior
Anything on the front half of the body
39
Internal
Inside the body
40
External
Outside the body
41
Lateral
Further away from the midline of the body
42
Medial
Closer to the midline of the body
43
DRAW A LONG BONE
44
DRAW A SYNOVIAL JOINT
45
DRAW THE STRUCTURE OF SKELETAL MUSCLE
46
Main function Protection
Protects soft tissue and vital organs
47
Main function- Support and structure
Provides framework for the body
48
Main function movement
Area for muscles to attach with tendons and joints allow different types of movement.
49
Main function- Red cell production
Red blood cells carry oxygen to working muscles
50
Main function-n- Storage of energy
Lipids are stored in bone marrow
51
Main function- Storage and release of minerals
Bones store and release essential minerals contributing to bodily functions released into blood
52
Examples of long bones
Femur, Humerus and Ulna
53
Example of flat bones
Skull, Ribs
54
Example of short bones
Carpals and Tarsals
