Spinal Nerves Quiz

The sympathetic division of the autonomic nervous system is responsible for the 'fight or flight' response. It controls things like heart rate, blood pressure, and respiration. This division uses a chain of ganglia called the paravertebral ganglia to send signals to the body.

Spinal nerves are the nerves that emerge from the spinal cord. They are responsible for carrying sensory and motor information between the central nervous system and the rest of the body. There are 31 pairs of spinal nerves, each corresponding to a segment of the spinal cord.

The posterior rootlet is the portion of a spinal nerve that carries sensory information, like touch, pain, and temperature, from the body to the spinal cord.

The paravertebral ganglia are chains of nerve cell clusters located along both sides of the spinal cord. These ganglia are part of the sympathetic nervous system, which controls the body's stress response. They are like small 'stations' where signals are relayed and processed.

The sympathetic chain ganglia are a series of interconnected ganglia that form part of the sympathetic nervous system. They are responsible for regulating various functions like heart rate, blood pressure, and digestion. They are like a 'relay system' for stress responses.
