Draw and label a typical motor neuron (include: dendrites, body, mitochondria, endoplasmic reticulum system, nucleus, axon, Schwan cells, telodendria).

Describe the role of the following in planning and executing movement:        spinal cord -           brain stem -         thalamus -           cerebellum -           basal ganglia (basal nuclei) -           cerebral cortex -

Define actin

Rachel is out playing in the dirt and cuts herself, unbeknownest to her a bacteria enters her system and moves retrogradely through the peripheral nerves to enter the central nervous system. Once there its toxins begin to interfere with the release of the neurotransmitter Glycine from the upper motor neurons of the direct motor pathway. this would lead to Group of answer choices spastic paralysis and atrophy of muscle tissue flaccid paralysis and atrophy of muscle tissue spastic paralysis and maintaining or increasing muscle tissue flaccid paralysis and maintaining or increasing muscle tissue not enough information is given to determine the correct response

Identify the primary functional roles of each part of the neuron; dendritic arbor, cell body, axon hillock, axon, and synaptic terminal.

MovementKnow the components of the motor control system   What are the components of the motor control system? Intro to neuroscience College-level   Please provide some pictures and visual explanations to these concepts. I need a visual answer and not just an essay. So, the explanation must include diagrams of the relevant component of the motor control system.

Binding of neurotransmitter to the motor end plate leads to depolarization because the neurotransmitter: a) opens ligand-gated sodium channels. b) opens voltage-gated sodium channels. c) opens ligand-gated potassium channels. d) opens voltage-gated potassium channels.

Jane is wishing to artificially stimulate neurotransmitter release by a motor neuron. She should be able to do this by electrically activating the neuron (TRUE or FALSE) and/or by injecting potassium ions into the synaptic terminal/knob region (TRUE or FALSE).

Which of the following would result in no movement (i.e. no activation of the motor cortex)? Stimulation of D2 Medium Spiny Neurons Stimulation of D1 Medium Spiny Neurons Inhibition of the Globus Pallidus Interna Inhibition of the Globus Pallidus Externa Both A & D are correct

The neural changes that occur with training might include all of the following EXCEPT: a.) An increased excitability of the spinal motor neurons b.) A decrease in the activity of the antagonist muscle to the the trained movement (better coordination) c.) Muscle hypertrophy d.) An increase in the ability to formulate a movement plan in the brain and consequently an increase in the descending drive to the spinal cord
