HUMAN ANATOMY
(I) GOAL

The broad goal of teaching of undergraduate students in Anatomy aims at providing
comprehensive knowledge of the gross and microscopic structure and development of human body
to provide a basis for understanding the clinical correlation of organs or structures involved and
the anatomical basis for the disease presentations
(II) OBJECTIVES

At the end of the course the students shall be
able to:
(A) Knowledge
Comprehend the normal disposition, clinically relevant interrelationships, functional and
cross sectional anatomy of the various structures in the body.
Identify the microscopic structure and correlate elementary ultra-structure of various organs
and tissues and correlate the structure with the functions as a prerequisite for
understanding the altered state in various disease processes.
Comprehend the basic structure and connections of the central nervous system and
analyse the integrative and regulative functions of the organs and systems. He/She shall be
able to explain the developmental basis of the major variations and abnormalities.
Demonstrate knowledge of the basic principles and sequential development of the
Organs and systems; recognize the critical stages of development and the effects of
common teratogen, genetic mutations and environmental hazards. He
/She shall able to explain the developmental basis of the major variations and
abnormalities.
(B)Skills
At the end of the course the student shall be able to:
Identify and locate all the structures of the body and mark the topography of the living
anatomy
Identify the organs and tissues under the microscope
Understand the principles of Karyotyping and identify the gross congenital anomalies.
Understand principles of newer imaging techniques and interpretation of Computerized
Tomography (CT) Scan sonogram etc.
Understand clinical basis of some common clinical procedures i.e. intramuscular and
intravenous injection, lumbar puncture and kidney biopsy etc.
8



(C)Integration
From the integrated teaching of other basic sciences, students
shall be able to comprehend the regulation and integration of the functions
of the organs and systems in the body and thus interpret the anatomical basis
of disease process.
