Question

1. a) Which of the following does NOT describe a process involved in the transmission of information by the nervous system?

A. Dendrites of neurons receive signals from the axons of other neurons.

B. Motor neurons send signals to muscle cells to produce muscle contractions.

C. Neurotransmitters transfer information across synapses between neurons.

D. Sensory neurons carry impulses from the central nervous system to muscles.

1. b) Which of the following best describes how the brain stem functions in the process of producing responses?

A. The medulla oblongata receives signals from motor neurons and transmits them to the pons.

B. The midbrain receives and integrates sensory information before sending it to the forebrain.

C. The pons controls the peripheral vision reflex, moving the head toward moving objects.

D. The thalamus controls involuntary processes, decreasing respiration rate during sleep.

Answer 1

1 a: D option is false because the sensory nerves carry the impulse from the sensory organs to the brain or spinal cord. While the motor neurons carry impulse from the brain or spinal cord to the muscles.

1 b: B option is true because the mid brain, which is located in the brain stem between the forebrain and hind brain acts as coordinator for the signals to and fro of the brain
