Answer: Thalamus
Question: Which of the following statements is true of the above answer? This component of the brain.
A. receives and evaluates almost all of the sensory nerve impulses from peripheral sensory receptors - True.
B. passes the information it receives from the sensory receptors to the temporal lobes of the cerebral cortex - True.
Relay neurons carry informations from sensory receptors and send them first to thalamus and then to particular regions of the cerebral cortex. Thalamus receives and evaluates almost all of the sensory nerve impulses from sensory receptors before passing the information to the cerebral cortex. From thalamus these informations pass to cerebral cortex and they end in different regions of the cerebral cortex; visual information ends in the occipital lobe, auditory in the temporal lobe, and somatic sensation in the parietal lobe.
C. is part of the brainstem and is continuous with the spinalcord - False.
D. regulates reflexes such as vomiting, coughing, swallowing, and gagging - False.
In the human brain, the brainstem includes three sections; the midbrain, the pons, and the medulla oblongata. Medulla oblongata is the lowest portion of the brain stem and is continuous posteriorly with the spinal cord. It contains the centers that control reflex actions such as vomiting, coughing, swallowing, and gagging.
