The central nervous system consists of a)the brain, spinal cord and cranial nerves b )the brain and spinal cord c)the brain, spinal cord and autonomic nervous system d)only the brain's neurons and glia 8. What part of the neuron is responsible for transmitting a signal to other neurons? Ajaxon b)dendritic spines c)soma d)dendrite e)postsynaptic membrane What type of neuron conducts messages directly to muscle fibers? A)reflex neuron b)sensory c)interneurons d)motor

Explanation / Answer

5. Ans -e. All of the above. The fact that the research team studied whether eating alone or with others made a difference contributed to the social level of analysis, looking at neurotransmitters fulfils the synaptic level of analysis,neural networks are the neural circuit level of analysis, and lastly the study of genes contributes to the molecular level of analysis.

6. Ans - c. Motor neurons which are a nerve cell forming part of a pathway along which impulses pass from the brain or spinal cord to a muscle or gland.

7. Ans. b. The brain and the spinal cord. The brain is protected by the skull and the spinal cord runs down the middle of the spine till the lumbar region.

8. Ans - a. Axon - The axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal. The larger the diameter of the axon, the faster it transmits information.
