Motor Pathway

This area of the frontal Lobe integrates and controls the mechanisms that govern voluntary movement

• Motor Cortex

• Sensory Motor Cortex

• Occipital Lobe

• Amygdala

• Pons

The cascade of the neurological mechanisms that control movement occur in this order

• motor cortex, brainstem, muscles

• muscles, brainstem, motor cortex

• brainstem, muscles, motor cortex

• brainstem, motor cortex, muscles

Two supportive structures in the brain that aid in integrating movement

• basal ganglion

• cerebellum

• primary sulci

• nodes of ranvier

Glutamate is a neurotransmitter that works as a

• excitatory NT (on switch)

• inhibitory NT (off switch)

• motivational NT

GABA is a neurotransmitter that works as a

• excitatory NT (on switch)

• inhibitory NT (off switch)

• motivational NT

Dopamine is a neurotransmitter that works as a

• excitatory NT (on switch)

• inhibitory NT (off switch)

• motivational NT

Match the condition to the symptoms

Hemiparesis

• Weakness of the right or left side of the body

• disruption of the glutamatergic and gabaergic pathways resulting in involuntary muscle movements

• characterized by a resting tremor, but the most debilitating symptom is severe due to death of dopaminergic neurons

• Genetic disorder inhibiting the motor pathway resulting in involuntary irregular movements and eventually dementia

• characterized by a lack of movement coordination resulting in abnormal gait, posture, or timing of coordinated movement

Match the condition to the symptoms

Overactive reflexes

• Weakness of the right or left side of the body

• disruption of the glutamatergic and gabaergic pathways resulting in involuntary muscle movements

• characterized by a resting tremor, but the most debilitating symptom is severe due to death of dopaminergic neurons

• Genetic disorder inhibiting the motor pathway resulting in involuntary irregular movements and eventually dementia

• characterized by a lack of movement coordination resulting in abnormal gait, posture, or timing of coordinated movement

Match the condition to the symptoms

Parkinson's

• Weakness of the right or left side of the body

• disruption of the glutamatergic and gabaergic pathways resulting in involuntary muscle movements

• characterized by a resting tremor, but the most debilitating symptom is severe due to death of dopaminergic neurons

• Genetic disorder inhibiting the motor pathway resulting in involuntary irregular movements and eventually dementia

• characterized by a lack of movement coordination resulting in abnormal gait, posture, or timing of coordinated movement

Match the condition to the symptoms

Huntington's

• Weakness of the right or left side of the body
