Explanation The spinal nerves branch into dorsal ramus, ventral ramus, meninges, and rami communicants. The rami contain both motor and sensory fibers. The dorsal ramus is posterior to the ventral ramus (anterior) and serves the skin and muscles of the posterior body trunk. It is usually smaller than the ventral ramus...

Chapter 7, Problem 29SAE

Summary Introduction

To review:

The regions of the body that are served by the dorsal rami of the spinal nerves along with the ventral ramus.

Introduction:

The spinal nerves are the mixed nerves that arise from the spinal cord, unlike the cranial nerves that arise from the brain. The spinal nerves act as a connection between the body and the spinal cord. Each of the spinal nerve has two roots, dorsal root and the ventral root.

San Andreas Transform Boundary Plate Motion The geologic map below of southern California shows the position of the famous San Andreas Fault, a transform plate boundary between the North American Plate (east side) and the Pacific Plate (west side). The relative motion between the plates is indicated by the half arrows along the transform plate boundary (i.e., the Pacific Plate is moving to the northwest relative to the North American Plate). Note the two bodies of Oligocene volcanic rocks (labeled Ov) on the map in the previous page located along either side of the San Andreas Fault. These rocks are about 23.5 million years old and were once one body of rock. They have been separated by displacement along the fault. 21. Based on the offset of these volcanic rocks, what is the average annual rate of relative plate motion in cm/yr?
