Usage examples of sensations.

In addition, sensations from muscles and joints continually arrive at the reticular activating system in the brain stem.

Since those nerves that receive sensations are most likely to be attacked, double vision, loss of the ability to feel, and other abnormal sensations are common symptoms.

Organs designed to receive such sensations are most reasonably located in the head, since that is the ground-breaking portion of the body.

Therefore, although the reptilian cerebrum is still mainly concerned with the analysis of smell and taste sensations, it is larger, and in the part of the cerebral cortex nearest the front end there is the development of something new.

It consists of tracts of nerve cell bodies involved with the receipt of sensations other than smell.

The sensations arising from the nerve endings in the skin and in the interior of the body are led through bundles of fibers up the spinal cord and into the brain.

Those reaching the sensory area are primarily the sensations of touch and temperature, together with impulses from the muscles which give rise to knowledge concerning body position and equilibrium.

The fact that the sensations are received at various horizontal levels of the nervous system shows that here, too, there is a longitudinal unification of function.

sensations from the foot are at the top of the area, followed successively as we go downward with sensations from the leg, hip, trunk, neck, arm, hand, fingers.

Below the area that receives finger sensations are the areas receiving sensations from the head.

Under ordinary conditions, sensations are constantly being funneled into the cerebrum and motor impulses are constantly being sprayed outward.

Even if many sensations were cut off, if you were surrounded by complete darkness and silence, if there were nothing to smell or taste, if you were floating weightless in space and could feel nothing, there would still be sensations arising from your own muscles and joints to tell you the relative position of your limbs and torso.

The thalamus acts as a reception center for the somesthetic sensations touch, pain, heat, cold, and the muscle senses.

The milder sensations from the muscles, the gentle touches, the moderate temperatures are passed on to the sensory area of the cortex.

It is as though mild sensations can be trusted to the cerebral cortex, where they can be considered judiciously and where reaction can come after a more or less prolonged interval of consideration.
