Gross / Macroscopic anatomy
3 categories of Gross/Macroscopic Anatomy
Systemic Anatomy
Regional Anatomy

DIVISIONS OF HUMAN PHYSIOLOGY
A. CELL PHYSIOLOGY
B. SPECIAL PHYSIOLOGY
C. SYSTEMIC PHYSIOLOGY
D. PATHOLOGIC PHYSIOLOGY
- the study of the functions of living cells
- the cornerstone of human physiology
Cell Physiology
is the study of the functions of specific organs
e.g. cardiac physiology-is the study of the heart function
Special Physiology
includes all aspects of the functions of specific organ
systems.
e.g. cardiovascular physiology, respiratory physiology
and reproductive physiology.
Systemic Physiology
is the study of the effects of diseases on organ or system functions.
Pathologic physiology
Homeostasis
*Maintenance of the body’s internal
environment
*Negative feedback loop
HOMEOSTASIS REGULATION
- Autoregulation
- Extrinsic regulation
-happens when there is environmental change and an automatic system change in the activities of a tissue, cell, or organ.
– cells lack oxygen, chemicals would be
released to dilate blood vessels
Autoregulation
-involves the endocrine and nervous systems, which are not inside the organs they regulate.
-during exercise nervous system
commands increase of heart rate so blood will circulate faster
Extrinsic regulation
ESSENTIAL LIFE PROCESSES
- Metabolism
- Responsiveness
- Movement
- Reproduction
- Differentiation
- Growth
– includes all the chemical processes that occur in the body.
Metabolism
– the body’s ability to react to changes in
environment both internally or externally.
Responsiveness
motion occurring inside the human body, either
the whole body or individual cells or even the organelles
within these cells.
Movement
– an increase in body size that results from an
increase in the size or number of cells.
Growth
– development of cells from an unspecialized to a specialized state.
Differentiation
LEVELS OF STRUCTURAL ORGANIZATION
OF THE BODY
- Chemical Level
- Cell Level
- Tissue Level
- Organ Level
- System Level
formation of new cells for growth, repair or
replacement or the production of a new individual.
Reproduction
- Smallest units of life
- Perform all activities necessary to maintain
life– metabolism, assimilation, digestion, excretion,
reproduction

The Anatomical Position
ANATOMICAL PLANES
- Median Plane
- Sagittal Plane
- Coronal / Frontal Plane
- Horizontal / Transverse Plane
Median Plane
Is a sagittal plane that through the midline of the body, dividing the body into equal halves (right and left) - Seeley’s
Sagittal Plane
Right and Left proportion
Coronal/Frontal Plane
Front and Back proportion
Horizontal/Trasverse Plane
Superior and Inferior proportion
Sections of the Body
- Longitudinal/Vertical Section - cut along the length of the organ
2.Transverse/ Cross Section - cuts completely through the organ
3.Oblique Section- a diagonal cut
