MEDSCI 142 - Nervous System
How do basal ganglia influence movement? - ✔ ✔ by regulating the
activity of upper motor neurons which originate in the motor cortex or
brainstem, which send motor info to the lower motor neurons
originating in the spinal cord or brainstem, and connect to muscles to
initiate muscle contraction and execution of movement
How does the cerebellum contribute to movement control? - ✔ ✔ it
receives input from sensory systems of the spinal cord and from other
parts of the brain, and integrates these inputs to fine-tune motor
activity
What are the main neurotransmitters of the brain? - ✔ ✔
Dopamine, glutamine, GABA, acetylcholine, norepinephrine and
seratonin
, Which neurotransmitters are excitatory? Inhibitory? - ✔ ✔
Acetylcholine and glutamate; GABA
Where would deep brain stimulation be applied in a Parkinson's
patient? - ✔ ✔ Sub-thalamic nucleus or globus pallidus interna
Which symptoms results from a lesion of the corticospinal tract on the
right side of the brainstem? - ✔ ✔ Spastic paralysis on the left side
of the body
Which symptoms results from a lesion of the primary motor cortex on
the left side of the brain? - ✔ ✔ Spastic paralysis on the right side of
the bodyA lesion encompassing the supramarginal and angular gyral
region on
the left side of the brain results in a problem with what? - ✔ ✔
Reading and writing
The medial lemniscus conveys sensory information from where to
where? - ✔ ✔ Gracile and cuneate nuclei to the thalamus
A lesion of the lateral spinothalamic tract on the left side of the cervical
spinal cord results in: - ✔ ✔ Loss of pain and temperature sensation
on the right side of the body
Do spinal cord lesions/injuries cause associative or dissociative
sensation loss? - ✔ ✔ Dissociative
Which part of the spinal cord contains myelinated axons from lower
motor neurons? - ✔ ✔ Ventral root
A person who suffers from excessive stimulation of the sympathetic
nervous system following emotional stress or exposure to cold
