Identify the CNS components that form the somatic motor pathways.

Injury to the extrapyramidal motor system does not cause paralysis of voluntary movement and gene spasticity. Explain why and discuss the major motor symptoms observed in extrapyramidal motor disorders.

Contrast the two major types of descending motor pathways interms of structure and function?

Cell bodies of UMN that synapse on LMN lie in all of these areas EXCEPT    a) Medulla            b) Thalamus            c) Pre-motor cortex            d) Pons            e) Primary motor cortex

What structural features of the primary motor cortex somatotopic map reflect the general principle of physiology that structure is a determinantand has coevolved function?

Motor neurons have many functions, which include to: Carry a nerve impulse away from the CNS Send sensory information to the CNS Detect a stimulus from a sensory receptor Transmit a nerve impulse to an interneuron Take an impulse from an effector to a sensory neuron

The shape of the cell bodies of upper and lower motor neurons are structurally classified as blank and blank, respectively

How is the information determined by the motor program?

Consider three alpha-motor neurons of different sizes: small, medium and large. All three neurons receive input from the same excitatory interneuron. When the interneuron fires action potentials at low frequency, only one alpha motor neuron fires action potentials. As the action potential frequency of the interneuron increases, two alpha-motor neurons are recruited, and at maximum frequency, all three are recruited. In what order would the three alpha-motor neurons have been recruited? Large first, then medium, then small. Small first, then medium, then large. Medium first, then small, then large. Medium first, then large, then small.
