Question

The thalamus __________.

A. is the region in which complex visual stimuli are distinguished and interpreted
B. is a "bridge" that relays nerve impulses between the cerebrum and cerebellum via the middle cerebellar peduncles.
C. is the structure that connects the right and left cerebral hemispheres
D. is a colletion of approximately 12 nuclei where every type of sensory impulse except olfactory impulses synapse;
E. it is the "gateway" to the cerebral cortex contains the nuclei of cranial nerves V-VII

Answer 1

D. Is a collection of approximately 12 nuclei where every type of sensory impulse except olfactory impulses synapse.

Step-by-step explanation:

The thalamus is a mass in the centre of brain where the sensory impulses arrive to be processed there or to continue up to the brain, the only impulse that is not processed there is the olfactory one. This travels directly to the brain. It has 12 nuclei, each of them has a specific function as regards the processing of information.

Answer 2

Answer: B. is a "bridge" that relays nerve impulses between the cerebrum and cerebellum via the middle cerebellar peduncles.

Step-by-step explanation:

The thalamus is a small structure in the brain that is located above the brain stem between the cerebral cortex and the midbrain. It has a lot of nerve connections to both. The major function of the thalamus is to pass motor and sensory signals to the cerebral cortex. Also, the information from the cerebellum and basal ganglia to the cerebral cortex are relayed through distinct thalamic nuclei.
