No. The ears and eyes work together to produce equilibrium, not the nose.

What is the fiber tract that carries impulses to the cerebrum and then to the lower CNS called?
This fiber tract is called the projection tract.
Olfactory in a human?
There is one located on each side of the brain connected to the olfactory tract, which leads into the temporal lobes it deals with the sense of smell.
What is the pathway of smell from the olfactory receptors to the brain?
The olfactory bulb is a small , match-head sized organ in the top of the nasal cavity,and is connected to hundreds of olfactory hairs, or cilia, which lie in a layer of mucous. These have receptor sites, and it is still not well understood how these work, but one theory is that the shape of the molecule (of the substance being smelt) and the way in which it locks onto the receptor determines the impulses sent to the brain. (the bulb is thought of as a direct extension of the brain) If this is true, it may help explain why with prolonged exposure to a smell, you will stop smelling it until you go outside and clear the nose and come back.The receptor sites become saturated with the molcules and stop sending nerve impulses.
The sense of smell is able to stimulate vivid memories because the olfactory tract passes through which part of the brain?
limbic
What is the bundle of nerve fibers that send messages to the brain which interprets them?
The nerves that carry impulses toward the brain are called efferent nerves. Afferent nerves carry impulses away. In way to remember this is afferent equals away.
Function of olfactory tract?
The olfactory tract is a bundle of axons connecting the mitral and tufted cells of the olfactory bulb to several target regions in the brain.
What is the origin of rubrospinal tract?
to convey impulses of equilibrium to anterior horn cells of spinal cord
Does the amygdaloid nucleus receive its afferent fibers from the olfactory tract?
Yes!

Nerve fibers of the olfactory tracts lead to?
The olfactory tract is split into medial and lateral. Their projections are to 5 different areas of the brain- anterior olfactory nucleus, olfactory tubercle, Piriform cortex, Amygdala, Entorhinal cortex The lateral tract originates from the olfactory epithelium separates into mitral cells and tuft cells. mitral cells synapses onto all 5 of the regions to ultimately synapse onto the orbitofrontal cortex via the thalamus or the frontal cortex. tufted cells on the other hand only synapse onto the anterior olfactory nucleus and the olfactory tubercle The medial or vomeronasal tract projects to mitral cells that synapse only to the Amygdala
What are the olfactory and non-olfactory components of limbic system?
oflactory components = olfactor bulb and tract + hippocampal formation + paraterminal gyrus + septum pellucidum + fornixnon-olfactory components = cingulate gyrus + parahippocampal gyrus

What tract carries sensory impulses from the lower limbs and inferior body trunk?
Fasciculus gracilis

What tract conveys nerve impulses for crude touch and pressure?
spinothalamic, it is a somatosensory pathway
