ANATOMY AND PHYSIOLOGY 1PERIPHERAL NERVOUS SYSTEMThis lab handout provides learning opportunities for the following learning objectives:Compare reflex pathways.Differentiate between cranial nerves by location and function.Identify the major peripheral nerves of the nerve plexi on cadavers/models.Identify the major components of the spinal cord and a spinal nerve.SPINAL CORD IDENTIFICATION:Identify the following structures on the cross-section andlongitudinal views of the spinal cord.Be prepared to identify these structures on a practical examination.___________Anterior horns___________Posterior horns___________Anterior median fissure___________Posterior median sulcus___________Anterior funiculi (columns)___________Posterior funiculi (columns)___________Lateral funiculi (columns)___________Conus medullaris___________Cauda equina___________Lumbar enlargement___________Cervical enlargementPNS IDENTIFICATION:Identify the following peripheral nervous system structures on the spinal cordmodels (cross-section).Be prepared to identify these structures for the instructor and on a practicalexamination.___________Dorsal root of spinal nerve___________Ventral root of spinal nerve___________Spinal nerve___________Dorsal root ganglionMICROSCOPIC ANATOMY OF THE SPINAL CORD and PNS:Observing a microscopicimage and a model of the cross-section of the spinal cord, identify the following structures.Be prepared toidentify these structures on a practical examination.__________Central canal__________Anterior gray horn__________Posterior gray horn__________Funiculi –text refers to these ascolumns______Anterior______Lateral______Posterior__________Anterior median fissure__________Posterior median sulcus1
SPINAL NERVE IDENTIFICATON: Identify the following plexi and the major nerves associated withthem on the cadaver.Be able to identify the major muscles innervated by these nerves (see table at end ofhandout).You will be responsible for identifying these nerves on a practical exam.__________Phrenic nerve__________Axillary nerve__________Radial nerve__________Ulnar nerve__________Musculocutaneous nerve__________Median nerve__________Femoral nerve__________Obturator nerve__________Sciatic nerve__________Tibial nerve__________Common fibular nerveREVIEW QUESTIONS:Complete the following review questions.1.Differentiate between a nerve and tract using neuron structures and nervous system location:Components of Neuron (axon,dendrite and/or cell body)Location in Nervous SystemNerve
