Study Objectives 1. In a cross section of a peripheral nerve, be able to identify the different connective tissue sheaths. 2. Describe the anatomic classification of nerve fibres and its relationship to their function. 3. Describe the mechanism of myelination…
Study Guidelines 1. Contrast electrical and chemical synapses and describe the differences between ionotropic receptors and metabotropic receptors. 2. List the three major second messenger systems in the CNS and the functions of a second messenger. 3. List the criteria…
Study Guidelines 1. List the different types of ion channels and provide a description of how they function. 2. Describe the resting potential with respect to the major ions involved in its formation. 3. Be able to distinguish and describe…
Study Guidelines 1. Give an account of neuronal structure. 2. Give an account of synaptic structure and function and outline the lock and key analogy used in pharmacology. 3. Explain how a demyelinating disorder can compromise conduction. 4. Draw up…
Study Guidelines 1. Be able to contrast the structure of the dura mater with that of the pia–arachnoid. 2. Be able to follow a drop of venous blood from the superior sagittal sinus to the internal jugular vein and from…
Study Guidelines 1. On simple outline drawings of the lateral, medial, and inferior surfaces of a cerebral hemisphere, learn to shade in the territories of the three cerebral arteries. 2. Identify the main sources of arterial supply to the internal…
Study Guidelines 1. Be able to recognise and label the locations of the ascending and descending pathways in the horizontal sections of the brainstem and spinal cord. 2. Be able to describe or trace the four decussations that occur as…
Study Guidelines 1. The most important objective is that you become able to recite all the central nervous system items identified in the magnetic resonance images without looking at the labels. 2. Try to get the nomenclature of the component…
Study Guidelines This chapter aims to give you sufficient insight into the embryologic development of the brain and spinal cord to account for the arrangement of structures in the mature nervous system. If not already familiar with adult brain anatomy,…
