The enteric nervous system innervates the A. skeletal muscles B. cardiac tissue C. digestive tissues D. respiratory tissues 33. All the following structures are found in the hindbrain except? A. Medulla Oblongata B. Pons C. Thalamus D. Cerebellum 34. Parkinson's disease result from death of certain cells in the substantia nigra thas failing to itter? A. Ach B. GABA C. Dopamine D. Serotonin E. Glutamate which accentuates the signal by innervating at the synaptic bulb, thus causing a further increase in neurotransmitter secretion A. Presynaptic Facilitation 35. One example of positive neural regulation is the B. Excitatory Postsynaptic Potential C. Inhibitor Postsynaptic Potential D. Myelination

Explanation / Answer

31. b) Aspartate

Aspartate is an amino acid that is used in the biosynthesis of protein. It is not a neurotransmitter.

32. c) digestive tissues

The enteric nervous system is a quasi autonomous part of nervous system. The digestive system is innervated by the ENS within the wall of gastrointestinal tract.

33. c) thalamus

Thalamus is located just above the brain stem between cerebral cortex and midbrain.

34. c) dopamine

Cells in substantia nigra produce dopamine
