VS 331 - Histology

Histology (microanatomy) is the study of the structure and function of cells, tissues, and organs. Particular emphasis is placed on histology at the light microscopic level. The course uses hundreds of high-resolution photographs and images of human and domestic animal tissues.

Histology laboratories involve finding and identifying histological structures at low, medium, high, and oil immersion views utilizing a cutting edge virtual microscope program. Students will have unlimited access to the virtual microscope as they develop their understanding of tissues in the course.

This course can be used to prepare individuals for material covered in: dental, pre-medical, pre-health, pre-clinical, and pre-veterinary programs. Careful attention has been given to include subjects that are essential to understanding the coursework involved in these programs.

I graduated from Colorado State University in 2006 with my DVM (Doctor of Veterinary Medicine) and concurrently received my certification in Veterinary Acupuncture (CVA). I have received certifications in Pain Management (CVPP) in 2012 and rehabilitation (CCRT) in 2013. I went on to practice for a few years in small animal medicine before teaching Anatomy, Ethics, Acupuncture, and Case Studies at Ross University School of Veterinary Medicine on the beautiful island of St. Kitts. I taught there for 6 years, returning stateside to get back into general practice again. After returning to Colorado I taught in a veterinary acupuncture course, a Canine Studies course in California, and practiced small animal medicine before returning to higher education full time at Colorado State University.
