Human anatomy is the scientific study of the body’s structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word “anatomy” comes from a Greek root that means “to cut apart.” Human anatomy was first studied by observing the exterior of the body and observing the wounds of soldiers and other injuries. Later, physicians were allowed to dissect bodies of the dead to augment their knowledge. When a body is dissected, its structures are cut apart in order to observe their physical attributes and their relationships to one another. Dissection is still used in medical schools, anatomy courses, and in pathology labs. In order to observe structures in living people, however, a number of imaging techniques have been developed. These techniques allow clinicians to visualize structures inside the living body such as a cancerous tumor or a fractured bone.

3. ANATOMY :- (Ana= up; To my= process of cutting)
It is the science of body Structure and the relationship
among them.
PHYSIOLOGY :- ( Physio= nature; logy :- Study of)
It is the science of body function i.e. how the body parts
work?

LIVING NON-LIVING

Movement Growth Differentiation
Metabolism Responsiveness
1. METABOLISM: - Sum of all chemical processes that occur in the body
Catabolism:- Breaking down of complex chemical substance into smaller one.
Anabolism:- Building up of a chemical substance from smaller one.
E.g. :- AA+AA+AA Protein (Anabolism)
Protein AA+AA+AA (Catabolism)
8. 2. RESPONSIVENESS:- It is the body ability to detect and respond to change in
its internal and external environment.
E.g.:- Decrease in body temp--------Internal environment
3. MOVEMENT: - Include motion of the whole body, individual organ, single cell
and even tiny structure inside the cell.
4. GROWTH: - Increase in body size
Increase size of existing cell
Increase no. of cells
or Both
9. 5. DIFFERENTIATION:-
Unspecialized cell Specialized cell
It is the process of a cell undergoes to develop from an unspecialized to
specialized.
E.g. Ovum Embryo Fetus Infant Child Adult
6. REPRODUCTION:- Formation of new cells
The production of new individual

11. BODY CAVITIES
• Confidential space within the body where the internal organs are
located.
• Providing specific place and shape.
• The body cavities separate, support and protect the organs placed
there in.

CAVITIES
THORACIC CAVITY
PELVIC CAVITY
CRANIAL CAVITY
ABDOMINAL CAVITY
14. CONT…
• Intracellular fluid (ICF):- Fluid within body cell.
• Extracellular fluid (ECF):- Fluid outside body cell.
• Interstitial fluid:- The ECF that fills the narrow space between the
cell of tissues.
Depending upon location ECF is :-
1. Within blood vessels is termed as – Blood plasma
2. Within lymphatic system is called as – Lymph
3. In and around the brain and spinal cord – Cerebrospinal fluid
4. In joints – Synovial fluid
5. In eye – Aqueous humor
15. HOMEOSTASIS
• Homeo--- Sameness
• Stasis--- Standing still
Definition:- It is the condition of equilibrium in the bodies internal
environment.
E.g.:- Blood sugar level- 70 to 110mg/100ml of blood
Homeostasis
External
Environment
e.g. Intense heat, lack
of O2
Internal Environment
e.g. Low blood
glucose level
Social Environment
e.g. Psychological
stress

16. FEEDBACK SYSTEM
• A feedback system is a cycle of events in which the status of a body
condition is monitored, evaluated, changed, remonitored and
revaluated.
• Controlled condition: - monitoring of variables such as BP, Blood
glucose level, Body temperature.
• Any disruption that changes a controlled condition is called a
stimulus.
Basic component :-
• Receptor
• Control centre
• Effector
