Respiratory and nervous system adaptations

The volume of air breathed in or out per breath is known as?

• Tidal volume

• Minute volume

• Vital capacity

• Residual volume

The maximal amount of air you can forcible expire after a maximal breath in is known as?

• Tidal volume

• Minute volume

• Vital capacity

• Residual volume

The long term adaptation to tidal volume is?

• Decreases

• Increases

• No change

How do you calculate minute volume?

• Tidal volume x stroke volume

• Tidal volume x breathing rate

• Stroke volume x breathing rate

• Breathing rate x heart rate

The long term adaptation to minute volume is?

• Decreases

• Increases

• No change

The inspiratory muscles increase in strength, increasing tidal volume. Which of the following is not a inspiratory muscle

• External intercostals

• Diaphragm

• Scalene

• Trapezius

Identify the following: Their role is to detect the length of muscle and relay information to the CNS causing muscle contraction to prevent injury.

• Golgi tendon organ

• Muscle spindles

• Acetylcholine

• Synaptic cleft

Identify the following: Their role is to detect the tension in a muscle, relay information to the CNS causing relaxation of the muscle to prevent injury

• Golgi tendon organ

• Muscle spindles

• Acetylcholine

• Synaptic cleft

What is the long term adaptation to muscle spindles?

• Decrease nervous inhibition, enhancing ability to increase force

• Increase nervous inhibition, enhancing ability to increase force

• Decrease nervous inhibition, reducing force output

• No adaptation

Acetylcholine is a neurotransmitter. What is it responsible for?

• Detecting increases in muscle length

• Reducing muscle contraction

• Creating action potential and the release of calcium

• Reducing action potentials
