vertebralnervesOver the Christmas holidays our BIMS faculty got many email greetings from former students.  One, however, included a phrase that completely went over my head.  Salvador Prieto is a recent McMurry graduate who is going to physician’s assistant school in Virginia.  In his holiday greeting to Dr. Larry Sharp (and shared with the rest of us) he made a special effort to thank him for SAME DAVE.  Seems that phrase was greatly appreciated by Sal and his classmates in their studies.

I had to ask Larry what that was about, and here’s his response:

Sal is referring to mnemonics that are used to help keep some basic neurological concepts straight.

 Sensory information from the periphery, to the brain is afferent; while motor information from the brain to the periphery is efferent…this is confusing and is easily kept straight by the mnemonic SAME, representing sensory, afferent, motor, efferent information.

 When talking about spinal nerve roots exiting the front or ventral horn of the spinal cord; and spinal nerve roots exiting the dorsal horn of the spinal cord, there is some confusion as to their actual function. Ventral nerve roots are for motor or efferent information; while dorsal nerve roots are for sensory or afferent information. This is always confusing to students, so an easy way to keep this straight is the mnemonic DAVE. Now, linking them both together, you have SAME DAVE, which will let you know function based on location: Sensory or Afferent information is always carried by the Dorsal nerve roots and Motor or Efferent information is always carried by the Ventral nerve roots.

You can now take this one step further when analyzing the pre- and post-synaptic neurons and recognize that the dorsal root ganglia are a collection of cell bodies outside the central nervous system, whose function is to transmit afferent or sensory information and thus are sensory neurons.  

There you have it – SAME DAVE and its importance to students eager to learn about how the nervous system works.  Just another example of how Larry’s Human Physiology course is preparing students for health professions schools.

Some May Graduates

by gwilson on Jun.26, 2009, under Students

The BIMS program is too new to have any graduates with a BS in Biomedical Science degree.  However several of the most recent McMurry graduates with other majors were heavily involved in BIMS courses.

david8web1Derek David distinguished himself on the baseball diamond and in the classroom.  As a player he was named the NCAA Division III Baseball Player of the Year for 2008 in his final year of eligibility.  This year, he took Genetics, Molecular Biology, and Microbiology among his courses to finish out his Biochemistry degree.  He begins his Doctor of Pharmacy degree in the fall.

sal2Salvador Prieto was born in Mexico but raised in Texas.  His Biology major was filled with BIMS courses as he prepared for a career in the medical profession.  During his junior year, he made the decision to pursue Physician Assistant training rather than the MD.  This fall he will begin the Masters in Physician Assistant program at Jefferson College of Health Sciences in Roanoke, VA.

whitney-tWhitney Truran graduated in December after completing her Biology degree and playing golf for McMurry.  An avid baseball and basketball fan, she was frequently seen talking sports with Dr. Tom Benoit and others when she was not hard at work as a lab assistant for the department.  This fall she begins a career as teacher and coach in the Houston area where her knowledge of biology and exceptional interpersonal skills should make her an instant success and highly effective teacher.

There are other stories to be told, but they will have to wait for a future post.
