TEACHING AND LEARNING METHODOLOGY
Departmental Faculty and Staff emphasizes on teaching basic fundamentals of Gross anatomy,
Microscopic anatomy and its correlation with function, developmental anatomy and anatomical basis of
occurrence of congenital defects, nerve lesions and its anatomical basis and the applied aspects of
relevant clinical conditions.
All divisions of Anatomy i.e. Gross, Histology, Embryology, Genetics and Neuroanatomy are taught
with the help of didactic lectures on specific topics followed by dissection / practicals. The general
pattern of teaching methodology followed by all the faculty members and teaching staff in the department
is :
1. Didactic Lectures : discussing the topic in detail in one hour lecture time.
Practicals
Learning objectives are given to students before each session.
2. Dissection : is done by students on the cadavers and is being assisted/supervised by a team of
teachers. Some prossected specimen/dissection are shown on Ultrascope which is telecasted on
TV monitors fitted in dissection Hall.
3. Video tapes of some dissections are also shown on TV after the completion of dissection of the part/
region to recaptulate the details of the part/region dissected.
4. Cross sections of whole body and brain are shown to correlate with MRI. X-rays are shown after
dissection of each region.
5. Self assessment MCQs are given at the end of dissection of each region and discussed with teachers
in-charge.
6. Handouts are given at the end of completion of part/region to the students to recaptulate and remember
the Gross anatomy, Neuroanatomy, Embryology and Histology.
7. In microanatomy, a preview of the slides is given on TV monitor in small groups to understand the
structural details of tissue/structure/organ.
8. In embryology, the serial sections of early chick embryos and pig embryos are demonstrated to
understand the sequence of events involved in development of various systems and to understand
the developmental basis of occurrence of various congenital abnormalities. Computer assisted
programs for understanding the normal development of organ/systems is also demonstrated. Specimen
and models depicting normal development of system are shown.
9. In genetics, the phenotype photographs, karyotyPes and pictures of various banding techniques are
shown to understand the chromosomal abnormalities and various syndromes.
10. In Neuroanatomy, the stained sections at various levels of brain and spinal cord are shown on slides
and computers to localize the cranial nerve nuclei and trace the origin, course and termination of
ascending and descending tracts in order to understand the effects produced as a result of lesions.
11. Case studies of neural lesions are discussed to understand the location and level of lesions.
12. Demonstrations : Mainly the bones of the entire body, few dissected specimen are taught in small
groups.
By a combination of the above teaching-Learning tools and modalities the student is able to understand
the development, gross and microscopic structure of the organ systems and gain an insight into the
structure-function correlation. This combined with the knowledge of applied/clinical anatomy provides
an understanding of the anatomical basis of health and disease.
