Flashcards in Exams 01 Deck (44):
How many bones are there in the body and name them
What are the functions of the skeleton?
•Support-keeps the body upright/provides a framework to support the muscles
•posture-skeleton gives correct shape to the body
•protection-the skeleton structure protects organs.
•movement-skeleton structure allows muscle attachment
•blood cell production-red blood cells produced in the bone marrow of large bones.
•mineral store-bones release into the blood as needed (e.g calcium)
How many muscles are there and what are they?
What is aerobic exercise?
Is is the use of oxygen for the duration of the exercise.
A marathon runner
What is Anaerobic exercise?
Anaerobic exercise doss not allow for the predominant usage of oxygen
What are components of fitness and how many are there?
What is the defenition and test for cardiovascular endurance?
The ability to continuously exercise without tiring.
Test is a multi stage fitness test
Example is a marathon runner
What is muscular indurance?
The ability of the muscle or group of muscles in the body to repeatedly contrast or keep going without rest.
1 minute press up test
What is speed?
The ability of the body to move quickly
30m sprint test.
What is strength?
The ability of a muscle to exert force for a short period of time.
Hand grip dynamometer test.
What is power?
The ability to exert maximal force in as short a time as possible.
Standing jump test.
What is flexibility?
The amount or range of movement that you can have around a joint.
Sit and reach test.
What is Agility?
How quickly you can change direction under control and maintaining speed,balance and power.
Illinois agility test.
What is reaction time?
The time it takes for initiate an action or movement.
Reaction time ruler test.
Sprint start in athletes
What is balance?
The ability to keep your body mass or centre of mass over a base of support.
Stork stand test.
What is co-ordination
The ability of repeating a pattern or sequence of movement with fluency and accuracy.
Wall throw test.
What is yellow elastic cartlidge?
Flexible tissue (part of the ear lobe)
What is Hyaline cartlidge?
It is found on the articulating surfaces of the bones,protects and allows movement between bones, can thicken as a result of exercise
What is White flexible cartlidge ?
Tough tissue that acts as a shock absorber, found in parts of the body with a great amount of stress
What is a synovial joint?
A free moving joint where synovial fluid is released when you exercise to stop bones grinding together.
What is a freely moveable joint?
The bones surface is covered in cartlidge and connected by a fiborous connevtive tissue copsulle lined with synovial fluid.
What is a ball and socket joint?
A ball and socket joint allows: felxion, extention,,rotation, circumduction, adduction and abduction
What is a hinge joint?
A hinge joint allows flexion and extension
What are ligaments?
Ligaments are attached to bones, help keep joints stable during movements and precent movements that are extreme and prevent dislocation
What are tendons?
Tendons attach muscles to bones, help transmit the power needed to move bones.
What happens to the tendons when a muscle contracts?
When a muscle contracts it pulls on the tendons; this pulls on the bones to which the tendons are attached and cause movement
What is the deffiniton if flexion?
Movement decreasing the angle between articulating bones
What is the definition of extension?
Movement increasing the angle between the articulating bones
What is the definition of abduction?
Movement away from the midline of the body
What is the definition adduction?
Movement towards the midline of the body
What id definition of rotation?
A circular movement around a fixed point
What id the definition of circumduction?
Movement patterns consisting of flexion, extension,abduction and adduction
What are the antagonistic pairs?
They are muscles that work together. As one muscle contracts the other relaxes to allow movement
What id the agonist in an atangonistic pairs?
The working muscle that produces the desired movement.
The prime mover.
It is also the muscle that contracts/ shortens in the movement.
An example is a bicep in a bicep curl
What is an antagonist in an antagonistic pair?
The muscle that controls the movement.
The muscle that relaxes and lengthens.
For example a tricep in a bicep curl is one example
What is a fixator?
It stabilises the joint
Name all there planes of movements
The frontal plane.
The transverse plane.
The sagittal plane.
What is the frontal plane?
The frontal plane splits my front from my back and the movement of the frontal plane is adduction and abduction,.
What is the transverse plane of movement?
This plane divides the body into top and bottom. Movements in the plane are rotational in nature, such as internal or external rotation.
What is the sagittal plane of movement?
It passes through the body front to back so dividing it into left and right. Movements in this plane are the up and down movements of flexion and extension
Name all three axis of rotations
What is a frontal axis?
Runs horizontally from the front to the back of your body and is formed by the intersection of the sagittal and transverse plane.
What is a transverse axis?
Is passed horizontally from left to right and is formed by the intersection of the frontal and transverse planes.
