Lab 2, Station 4: Spinal Cord

Lab 2 navigation Complete anatomy Spinal nerves Identify the following on the spinal cord prosection or isolated spinal cord: ■Dorsal and ventral roots—because the cadaver is prone, only the dorsal roots will be easily visible. Rootlets gather together to form the roots. ■Dorsal root ganglion—what does this contain? ■Spinal nerves—formed by the union of dorsal […]
Lab 2, Station 5: Spinal Nerves

Lab 2 navigation On the whiteboard, draw a cross section of the spinal cord and spinal nerves. You can omit the vertebra in your drawing if you like. Label the following in your drawing: ■Dorsal and ventral horns of gray ■Dorsal and ventral roots ■Dorsal root ganglion ■Spinal nerve ■Dorsal and ventral rami Questions Which […]
Lab 2, Station 6: Muscles of the Back and Posterior Shoulder

These are worth knowing about since back pain and muscle spasm are so common. Splenius Muscles Splenius translates to “bandage”—indeed these muscles look like bandages applied to the […]
Lab 2, Station 3: Imaging of the Vertebral Column

Lab 2 navigation Radiography of the Spine Radiography involves using radiation (x-rays) to provide images of the tissues, organs, and bones, that comprise the human body. To create a radiograph, a patient is positioned so that the part of the body being imaged is located between an x-ray source and an x-ray detector. When the […]

Lab 2 navigation Complete anatomy Sacrum ■Sacrum (5 fused vertebrae) ■Promontory ■Alae (singular is Ala = “wing”). There are two of these, on either side of the promontory ■Anterior and posterior sacral foramina ■Sacral canal ■Sacral hiatus ■Coccyx (4 vertebrae fused into 1-2 pieces) Figure 2.8.

Optional reading Clinically Oriented Anatomy, 8th ed., chapter 5, Abdominal viscera. Recall from The peritoneal cavity and mesenteries that the peritoneal cavity is divided into supracolic and infracolic regions, using the transverse colon and its mesentery (transverse mesocolon) as the borderline. In Organs in the supracolic region, the supracolic organs were described. In this chapter […]
