Bones, Joints & Muscles
The longest bone in the body
What is the femur?
Toes lifting up
What is dorsi flexion?
This blood vessel carries deoxygenated blood from the heart to the lungs for oxygenation.
What is the pulmonary artery?
This energy system provides rapid energy for short bursts of activity, lasting about 10 seconds.
What is the ATP-PCR system?
This term describes the curved path an object follows when launched into the air, affected by factors like angle, velocity, and gravity.
What is projectile motion?
Technical name for the jaw bone
What is the mandible?
Lifting the arm in front of you from the shoulder
What is shoulder flexion?
These tiny air sacs in the lungs are where gas exchange occurs between the air and the blood.
What are the Alveoli's?
This energy system uses oxygen to produce ATP for sustained, long-duration activities, relying on carbohydrates, fats, and proteins as fuel.
What is the aerobic system?
This concept in biomechanics refers to an object's resistance to movement or change in position, influenced by factors such as base of support and center of gravity.
What is stability?
type of joint the ankle is
What is a hinge joint?
With the elbow locked in the body and forearm extended, moving the forearm towards the middle of the body
What is internal shoulder rotation?
This muscle plays a crucial role in breathing by contracting and flattening to allow the lungs to expand.
What is the diaphragm?
This term refers to the maximum amount of oxygen the body can utilise during intense exercise and is a key indicator of cardiovascular fitness.
What is V02 max?
This principle involves combining the forces of different body parts in a sequence to produce maximum force or momentum, often seen in activities like throwing or jumping.
What is Force summation?
Muscle on the front of the shin
What is the tibialis anterior?
This type of muscle contraction involves the muscle generating force without changing its length.
What is an isometric contraction?
This powerful chamber of the heart pumps oxygenated blood to the body through the aorta.
What is the left Ventricle?
This process breaks down glucose to produce energy anaerobically, creating ATP quickly but only for short to medium durations, and can lead to lactic acid build-up.
What is glycolysis?
This law of motion states that the force applied to an object is equal to its mass multiplied by its acceleration.
What is Newtons 2nd law?
4 types of bones
What are short, long, irregular and flat bones?
These pairs of muscles work in opposition to each other, with one contracting while the other relaxes to create movement.
What are antagonistic muscle pairs?
These two large veins return deoxygenated blood from the body to the right atrium of the heart.
What is the superior and inferior vena cava?
This measurement indicates the force of blood against the walls of arteries, recorded as two numbers: systolic over diastolic.
What is blood pressure?
In biomechanics, this term refers to the change in momentum of an object, calculated by multiplying the force applied by the time over which it is applied.
What is impulse?
