Q

How does the skeleton help create movement

A

Skeleton provides point of attachment for tendons and muscles. The muscles will then contract which will pull on bones which create movement

Q

What do short bones allow

A

They enable finer and controlled movements such as articulation of the fingers

25
What do flat bones do
They protect organs from damge
26
What are the functions of the skeleton
Support Protect Movement Shape Mineral storage Production of blood cells
27
How does the skeleton support our body
It keeps up upright and keeps all of our body parts in the correct positions
28
How does the skeleton protect our body
Flat bones protect vital internal organs that would otherwise be vulnerable to damage from impact
29
How does the skeleton provide movement
Bones at as a point of attachment for the muscles which aide the movement
30
How does the skeleton affect the shape of our body
The bones play a role in the physical build of people and athletes and their improved performance in certain sports as a result E.g. people with long bones in the arms and legs have an advantage in a sport like basketball due to height and are more suited to play professionally
31
How does the skeleton provide mineral storage
Bones act as a storage for minerals like calcium and phosphorus which can be released of the body has an essential need for them
32
How does the skeleton help in blood cell production
Some bones have hollow openings in its centre, these contain bone marrow One of the functions of bone marrow is that it is site of blood cell creation such as red and white blood cells
33
Function of red and white blood cells
Red blood cells carry oxygen around the body using haemoglobin for respiration White blood cells help fight infections by destroying pathogens
34
How many muscles are in the body
There are around 600 muscles
35
What are the roles of muscles
Movement of bones Cardiac muscles cause the heart to beat Smooth muscle around the organs help with systems like digestion
36
Muscles found in the front of the chest and stomach
Pectorals Rotator ciff Biceps Abdominals
37
Muscles found in the back and lower back of the body
Deltoid Triceps Gluteals
38
Muscles found in the legs (front and back)
Front: quadriceps, tibialis anterior Back: hamstrings Gastrocnemius and hip flexors found in front and back
39
What is the function and the position of the latissimus dorsi
Connected to the humerus bone in the arm Helps move the shoulder and the upper arm Important for sports like climbing
40
What is the function and position of the deltoid
Positioned over the top of the shoulder Helps raise the arms
41
What is the function and the position of the rotator cuffs
Connect to the upper arm at the shoulder Help rotate and extend the shoulder Used during bowling in cricket and baseball
42
What is the function and the position of the pectorals
Muscles in front of the chest that connect with the shoulder Assist with the movement of the shoulder and arm bones Example is throwing a ball underarm
43
What is the function and the position of the biceps
Large muscle in front of the upper arm which connects to the lower arm Helps raise the lower arm causing flexion at the elbow Important during the action of lifting
44
What is the function and the position of the triceps
Large muscles in the back of the upper arm and connects with the lower arm Helps to straighten the arm causing extension at the elbow
45
What is the function and the position of the abdominals
Groups of muscles located in the lower front of the body between the ribs and pelvis bones Helps stabilise the core of the body and support the internal organs near that area Assist with movements such as twisting the waist, sitting up and bending to the side
46
What is the function and the position of the hip flexors
Group of muscles that connect around the pelvic bone Help raise and lower and rotate the femur Important for running as well as kicking sports such as taekwondo and running
47
What is the function and the position of the gluteals
Muscles of the buttocks Position around the outside of the back of the pelvis bones Help with the movment of the upper leg and knee joint Important for sports like cycling and rowing
48
What is the function and the position of the hamstrings
Group of three muscles in the back of the thigh of the upper leg What is the function and the position of the Enable flexion of the leg at the knee
49
What is the function and the position of the quadriceps group
Group of muscles at the front of the thigh Straghten the knee causing extension at the knee Important for moving the leg forward like in football
50
What is the function and the position of the gastrocnemius
Found in the calf at the back of the lower leg Flexes the knee and foot Essential for the activites of running and jumping
51
What is the function and the position of the tibialis anterior
Found in the shin at the front of the lower leg Helps to draw the foot up at the ankle during walking or running
52
What is a tendon
Length of strong connective tissue that connect muscle to bond They are tough and inelastic so the do not stretch when the muscle is contracting and pulling on the bone
53
What is the synovial joint
Most common type of join in the human body Characterised by a joint cavity filled with a lubricating synovial fluid
54
What is the purpose of synovial fluid
It reduces friction between two bones
55
State the structure of a synovial joint
Joint between two bones which has a joint cavity in betwwem filled with synovial fluid The fluid will be produced by the synovial membrane which surrounds the joint The joint capsule then surrounds the membrane and seals the joint space and providing stability to the joint. It is made from tough fibrous tissue
56
What is the synovial joint capable of
Capable of variety of different movements But it depends of the structure within the joint and the joint type and the ligaments
57
Type of synovial joint
Ball and socket Hinge
58
Example of ball and socket joint
The hip joint
