Anatomy (morphology) -- study of structure of human body ... Closely related to physiology --
study of body functions
Subdisciplines (Branches) of Anatomy
Gross anatomy - body structure seen by naked eye
Bones, lungs, muscles
Seen by dissection
o Studies of Gross Anatomy
Systematic -- all organs studied together
Studying muscular system, consider muscles of ENTIRE body.
Regional -- structures in single body region studied as a group.
Medical school
Injuries/diseases involved in specific regions
Microscopic anatomy (histology) -- study of tissue that can only be seen w/ a microscope
Developmental anatomy -- structural changes occurring in body throughout life
Embryology -- study of how body structure form/develop before birth
Pathological -- structural change in cells, tissues, organs caused by disease
Radiographic -- internal body structures using X-Rays
Functional morphology -- functional properties of body structures and looks at their
efficiency of designs.
Hierarchy of Structural Organization
1. Chemical level
a. Atoms (carbon, hydrogen, oxygen etc..)
b. FORM molecules (CO2/H2O) and
i. larger macromolecules (carbohydrates[sugars[, lipids [fats], proteins, nucleic
acids [DNA/RNA]
Building blocks of structure of cellular level --> cellular organelles
2. Tissue level
Group of cells working together to perform common function.
Only 4 tissues make up all organs in human body
1. Epithelial
a. Lining tissue
2. Connective tissue
a. Support/protect
3. Muscle tissue
a. Produce movement
4. Nervous tissue
a. Internal communication by electrical impulses
3. Organ level
