26
What are your feet
Metatarsals
27
What are your toes
Phalanges
28
What are the three types of joints
Fibrous Cartilaginous Synovial
29
What is the fibrous joint
No movement from example the skull
30
What is the cartilaginous joint
Slightly moveable for example ribs and sternum, clavicle and sternum
31
What is synovial joints
Freely move Able for example shoulder, knee, ankle, elbow
32
What are the 6 types of synovial joints
``` Gliding Hinge Pivot Ball and socket Saddle Ellipsoid ```
33
What is the gliding joint in terms of synovial joints
Bones gliding along the surface of each other
34
What is hinge joints in terms of synovial joints
Movement in one place - flexion an extension for example elbow and knee
35
What is pivot joint in terms of synovial joints
Rotation of one bone around the other
36
What is a Ellipsoid joint in terms of synovial joints
Allow shallow movement in all directions for example wrist ankle
37
What is a saddle joint in terms of synovial joints
Allows shallow movement in all directions for example thumb
38
What is a ball and socket joint in terms of synovial joints
Allows large movement in all directions for example hip and shoulders
39
What are the 12 types of movements?
``` Extension flexion Dorsiflexion Plantarflexion Rotation Abduction Adduction Circumduction Pronation Supination Inversion Eversion ```
40
What is flexion
Decreasing the angle of a joint
41
What is flexion
Increasing the angle of a joint
42
What is abduction
Away from the middle of the body
43
What is adduction
Towards the the middle of the body
44
What is circumduction
Combination of flexion, extension, abduction and adduction
45
What is rotation
Movement of one bone around another
46
What is pronation
Rotate palm downwards
47
What is supination
Rotate palm upwards
48
What is inversion
Sole o the foot points inwards
49
What is eversion
Sole of the foot points outwards
50
What is dorsiflexion
Points toe upwards
51
What is plantarflexion
Points toe downwards
52
What are the 3 major types of muscles
Smooth muscles Cardiac muscles Skeletal muscles
53
Where are skeletal muscles found
Found in the internal organs such as the intestines (involuntary muscles)
54
Where are the cardiac muscles found
Found only in the heart ( involuntary - constantly working)
55
Smooth muscles
Primary function is movement (voluntary muscles - under our control)
56
What are the 3 functions of the muscles
Posture movement Maintaining homeostasis
57
What is posture in terms of a function of muscles
Muscles and ligaments act to stabilise joints and maintaining an upright position
58
What is movement in terms of a function of muscles
Contraction of muscles pulls on bones which allows movement to occur at joints
59
What is maintaining homeostasis in terms of a function of muscles
Cardiac and smooth muscles work to maintain homeostasis within the body
60
What are the 3 types of muscular contractions
Concentric contraction Eccentric contraction Isometric contraction
61
What is concentric contraction
Results in shortening of the muscles length
62
What is essential contraction
Results in lengthening of the muscle
63
What is isometric contraction
Tension increases, but no change in muscle length or the joint angle
64
What is gas exchange
Occurs in the lungs to remove CO2 from the blood and gives O2
65
What are the 2 mechanics of breathing and explain them
Inhalation: intercostal muscles contract and diaphragm becomes flatter - increases volume of lungs Exhalation: intercostal muscles relax and diaphragm becomes dome shaped - decrease volume of lungs
66
What does the respiratory system do
Takes air from the atmosphere to be delivered to the blood
67
What are the 2 types of blood vessels and explain them
Arteries: Carry blood away front the heart to the cells Veins: carry blood toward the Heart
68
What are the 3 types of functions of the cardiovascular system
``` #1: carries oxygen and nutrients to the cells of the body #2: removes carbon dioxide and waste #3: transports chemicals assisting in the growth, maintenance and repair of the body’s tissue and resistance against disease ```
