Actual Question and Answer (2026/2027) |
Updated Edition
• What is the neural circuitry that travels outside the spinal cord? -✓✓ Peripheral
nervous system
• Acetylcholine -✓✓ A neurotransmitter that enables learning and memory and also
triggers muscle contraction
• Which of the following is a sensory receptor within a muscle that detects changes in
length and helps regulate contraction? -✓✓ Muscle spindle
• Which of the following are branches of the cell body that act as receivers, collecting
information from other neurons? -✓✓ Dendrites
• A cascade of events, resulting in muscle contraction, is triggered when which of the
following chemical neurotransmitters binds to receptors on the muscle? -✓✓
Acetylecholine
• Which division of the peripheral nervous system controls voluntary movement? -✓✓
Somatic nervous system
• Which type of motor unit can contract for many hours, or even days if necessary? -✓✓
Slow (S) of Motor Unit
• Which type of motor unit has a large motor neuron and consists of a large bundle of
type IIx muscle fibers? -✓✓ Fast fatigable (FF)
• Voluntary movement starts in the -✓✓ Cerebral cortex
• Which of the following is the process that allows a muscle spindle to contract at the
same rate as the muscle where it resides? -✓✓ Alpha-gamma co-activation
• motor unit recruitment -✓✓ recruitment of more muscle fibers through motor unit
activation
• lower motor neurons -✓✓ axons leave the CNS, extend through PNS to skeletal
muscles. Cell bodies in anterior horns of spinal cord and in cranial nerve nuclei of
brainstem
• There are 31 pairs of nerves in the human body. -✓✓ True
