With respect to the image below which shows the flow of somatic sensory information  from the periphery into the spinal cord, for the pathways shown in panel A, where are the second order neurons located? 

The concept of labelled lines for sensory processing can be applied to somatic sensory processing to distinguish 

In the image below, the cell bodies of motor neurons controlling skeletal muscle are indicated by the label

In the image below, the ventral (front) surface of the spinal cord is indicated by the label

In the image below, these are the oldest evolutionary regions of the brain and control vegetative functions like respiration and the cardiovascular system.

In the image below, which label identifies the area most directly involved in the release of hormones into the blood stream?

In the image below, the spinal nerves, containing sensory and motor nerves, are indicated by the label

In the image below, damage to the area with this label is most associated with personality changes after accidents

In the image below, which label identifies the area which is most likely to  be involved in higher brain functions, like personality, aggression, decision-making etc?

In the image below, which label identifies the area which is most likely to  be involved in control of muscle?
