Movement
Comprehensive Test Review (Qns & Ans)
2025
1. Which part of the brain is primarily responsible for the
planning and execution of voluntary movements?
- A) Cerebellum
- B) Motor Cortex
- C) Hippocampus
- D) Amygdala
- ANS: B) Motor Cortex
©/2025
, - Rationale: The motor cortex, located in the frontal lobe, is
responsible for the planning and execution of voluntary
movements.
2. What is the primary function of the basal ganglia in motor
control?
- A) To coordinate balance and posture
- B) To initiate and regulate voluntary movements
- C) To process sensory information
- D) To modulate autonomic functions
- ANS: B) To initiate and regulate voluntary movements
- Rationale: The basal ganglia are involved in the initiation
and regulation of voluntary movements by modulating motor
pathways and ensuring smooth, coordinated actions.
3. Which neurotransmitter is primarily involved in transmitting
signals in the neuromuscular junction?
- A) Dopamine
- B) Serotonin
- C) Acetylcholine
- D) Glutamate
- ANS: C) Acetylcholine
©/2025
, - Rationale: Acetylcholine is the neurotransmitter that
transmits signals from motor neurons to muscle fibers at the
neuromuscular junction, triggering muscle contraction.
Fill-in-the-Blank Questions
4. The __________ pathway is a major motor pathway that
originates in the motor cortex and projects to the spinal cord to
control voluntary movements.
- ANS: Corticospinal
- Rationale: The corticospinal pathway, also known as the
pyramidal tract, is a major motor pathway that originates in the
motor cortex and projects to the spinal cord, controlling voluntary
movements.
5. __________ are specialized sensory receptors in muscles that
detect changes in muscle length and tension.
- ANS: Muscle spindles
- Rationale: Muscle spindles are specialized sensory
receptors located in muscles that detect changes in muscle length
and tension, providing feedback for the regulation of muscle
activity.
6. The __________ is a structure in the brainstem that plays a
critical role in maintaining balance and posture by integrating
sensory input from the vestibular system.
