If you are maintaining your current body weight, you are in caloric balance. If you need to gain weight or to lose weight, you'll need to tip the balance scale in one direction or another to achieve your goal.
The ventral posterior nucleus is the somato-sensory relay nucleus in thalamus of the brain. Ventral posterolateral nucleus, which receives sensory information from the body. 2  Ventral posteromedial nucleus, which receives sensory information from the head and face via the trigeminal nerve.
The dorsal root is sensory (all neurons conduct impulses into the spinal cord) while the ventral root is motor (all neurons conduct impulses out of the spinal cord). The dorsal root has a ganglion that contains the cell bodies of the sensory neurons that pass through the dorsal root.isceral efferent neurons are motor neurons that conduct impulses to smooth muscle, cardiac muscle, & glands. These neurons make up the Autonomic Nervous System. Some visceral efferent neurons begin in the brain; others in the spinal cord.
