Muscles
During the downward phase of a bicep curl, the biceps brachii is performing this type of contraction.
Eccentric
This mineral gives bones their hardness and strength and is stored in large quantities within the skeleton.
Calcium
Oxygen moves from the alveoli into the capillaries because the partial pressure of oxygen is higher in the alveoli than in the blood. This movement occurs via:
Blood leaving the left ventricle must pass through this valve before entering the systemic circulation.
Aortic Valve
This degenerative joint condition is characterised by the gradual breakdown of articular cartilage, often causing pain, stiffness and reduced joint function.
Osteoarthritis
A rupture of the Achilles tendon would most directly impair this movement at the ankle joint.
Plantar Flexion
This structure covers the ends of bones within a synovial joint and reduces friction during movement.
Articular Cartilage
If the pressure inside the lungs becomes lower than atmospheric pressure, this phase of breathing will occur.
Inspiration
During exercise, blood vessels supplying the digestive system undergo this process to redirect blood to working muscles.
Vasoconstriction
A basketball player lands awkwardly on an opponent's foot, causing the ankle to roll inward and damaging the lateral ligaments. This injury mechanism is known as:
Ankle Inversion
This muscle fibre arrangement is found in the deltoid and allows force to be generated from multiple directions.
Multipennate
This region of the vertebral column contains five vertebrae and is primarily responsible for supporting the weight of the upper body.
Lumbar
This chronic adaptation to aerobic training increases the number of blood vessels surrounding muscle fibres, improving oxygen delivery and waste removal.
Increase Capillarisation
If the Bundle of His and Purkinje fibres stopped conducting electrical impulses, these chambers would be most directly affected.
Ventricles
Unlike a strain, an injury to this structure would be classified as a sprain.
Ligament
This muscle fibre arrangement has a thick belly and tapers at both ends, allowing for a large range of motion and relatively fast contractions.
Fusiform
This type of fracture occurs when a bone breaks due to repeated loading that exceeds the rate of bone remodelling.
Stress Fracture
This measure represents the maximum amount of oxygen an individual can consume, transport and utilise per minute during maximal exercise.
VO2 Max
During exercise, a greater arteriovenous oxygen difference indicates that working muscles are extracting more of this substance from the blood.
Oxygen
A basketballer lands from a rebound and the knee collapses inward while changing direction. This movement pattern is a major risk factor for injury to this ligament.
ACL
According to the sliding filament theory, this molecule is required to break the bond between actin and myosin following a power stroke.
ATP
The Achilles tendon attaches to this bone of the foot.
Calcaneus
This method of heat transfer occurs when body heat is transferred through direct contact with a cooler surface.
Conduction
During exercise, venous return increases partly due to this mechanism, where contracting skeletal muscles compress veins and push blood back towards the heart.
Muscle Pump
A footballer sustains a syndesmosis injury. The damaged ligaments are located between these two bones.
