What is the function of the myelin sheath in a neuron?
To transmit electrical signals
To release neurotransmitters
To insulate the axon and increase signal transmission speed
To contain the nucleus and organelles
A motor unit consists of (a)
According to the 'All or Nothing' law, when will a muscle fibre contract?
Only if the stimulus is below its threshold
Only if the stimulus reaches or exceeds its threshold
Only if the stimulus is above its maximum threshold
Only if the stimulus is at its minimum threshold
What is the first type of motor unit recruited according to the Size Principle of Motor Unit Recruitment?
Larger motor units with faster fibres
Smaller motor units with slower, fatigue-resistant fibres
Larger motor units with fatigue-resistant fibres

Match the following roles with their corresponding muscle functions in the stretch reflex.
To detect excessive tension in the muscle
Golgi tendon organ function
To detect a stretch in the muscle
Muscle spindle function
To inhibit motor neurons
Reciprocal inhibition
To relax the muscle
Autogenic inhibition
What triggers the inverse stretch reflex?
Muscle spindles detecting a stretch
Golgi tendon organs detecting excessive tension
Sensory neurons transmitting a signal to the brain
Motor neurons contracting the muscle
What is the function of Golgi tendon organs?
To monitor changes in muscle length
To detect tension in the muscle-tendon complex
To activate the stretch reflex
To contract the muscle
What is autogenic inhibition?
A process where a muscle contracts when it experiences excessive tension
A protective mechanism where a muscle relaxes when it experiences excessive tension
A process where the contraction of one muscle group causes contraction in the opposing muscle group
A mechanism that increases muscle force production
What is reciprocal inhibition?
A process where the contraction of one muscle group causes relaxation in the opposing muscle group
A process where both muscle groups contract simultaneously
A mechanism that prevents muscle contraction
A process that increases muscle tension
Match the following types of training with their effects on muscles.
Strength training
Increases muscle mass and strength
Endurance training
Enhances the oxidative capacity of muscles

What is the function of the axon terminals in a neuron?
To receive signals from other neurons
To transmit electrical signals to other neurons, muscles, or glands
To release neurotransmitters
To insulate the axon
