BME 402 Material Review not due Gross Anatomy Peripheral Nervous System (PNS): Develop a good overview knowledge of the images, text and captions surrounding Figs. 1-5, 9-11 in ch. 49. Be able to write a one paragraph essay (100-200 words) that explains what the PNS is and does, its major subdivisions, it's anatomical whereabouts, its modes of action, etc. We did not cover this in class. Central Nervous System (CNS): be Be able to list several salient facts about each of the major subdivisions of the CNS, and draw or identify them on a picture (e.g. be able to label Box 1-1, and in ch. 17 Figs. 2-5, 12, 13, and Fig. 19-1). As for the structure of neural tissue, understand and be able to define and draw or give examples of what is meant by topography, convergence/divergence, symmetry, lamination, columnar organization, contralaterality, and reciprocal connectivity. Muscle Force Be able to draw stretch reflex circuit with reasonable anatomical detail in and around the spinal cord and in and around the muscle. Be able to identify/explain muscle unit, motor unit, motor neuron, motor nucleus. Know how force is graded, with reference to 3 types of motor units (see Figs. 34-8,9), recruitment and size principle, and rate codes. Spinal Cord and Descending Motor Pathways Be able to draw a nice labelled picture of spinal cord cross section including all main locational/anatomical descriptors (grey vs. white, dorsal/ventral horn, etc.), DRG, axonal columns, proximal/distal axis in grey matter, etc. Understand spinal-reflex-related figure contents in ch. Figs. 36-1 through 36-7. For locomotion, focus on ch. 37, Figs. 2, 4, 10, and 11. Understand the basic plan of the descending motor pathways, including figs. 33- 12, 14, and 15, and know what kinds of movements are represented in each path. Voluntary Movement Know (and be able to point out on a picture) the 3 main cortical areas involved in voluntary motor control and their interconnections. Know the response properties of the neurons, i.e. what aspect of movement or force is encoded in the responses of individual

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
