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.
A deep sulcus (anterior median fissure) runs on the ventral side of the spinal cord. Its dorsal counterpart is the rather flat posterior median sulcus. Laterally on both sides of the anterior median fissure the anterolateral sulci mark the exits of the anterior roots.The posterior roots enter the spinal cord through the posterolateral sulci on the dorsal side.The spinal ganglia which contain the perikarya (cell bodies) of the sensory neurons are located within the posterior roots.he posterior roots enter the spinal cord through the posterolateral sulci on the dorsal side.
