1. PLACE OF THE COURSE IN THE BVMS DEGREE CURRICULUM
Veterinary Anatomy (including histology and embryology) is a major component of both 1st and 2nd Year BVMS courses.
The aims, objectives and course content will be given in detail for the 2nd Year BVMS course.
2. aIMS OF tHE course in veterinary anatomy
It is intended that after completing the undergraduate course in Veterinary Anatomy the student will be able to progress to the paraclinical and clinical years with a thorough understanding of the fundamentals of veterinary anatomy, beginning with the development, and including ultrastructure and the microscopic anatomy as well as the gross anatomy of the domestic animals.
3. LEARNING OBJECTIVES FOR THE SECOND YEAR COURSE
On completion of the whole two year course you should have an understanding of the development, and functional gross and microscopic anatomy, of the cells, tissues, organs and body systems of both the common domesticated mammalian species and other species of considered veterinary importance. An understanding of the relevance and application of veterinary anatomy to the paraclinical and clinical years of the course should also be apparent.
The veterinary anatomy course is integrated, as far as possible, with that of veterinary physiology.
4. COMPONENTS OF THE COURSE
Introductory Session
Objectives
· To continue to develop those skills initiated in First Year, i.e.
· To be able to apply correct anatomical terms when giving topographical description of directional or positional anatomical detail, and to understand the nomenclature for the planes used in anatomical presentation of specimens.
