Anatomy VS Physiology
anatomy is the study of structure whereas physiology is the study of how body parts function
Embryology is the study of
the first eight weeks of development after fertilization of a human egg.
Developmental biology is the study of
the complete development of an individual from fertilization to death
Cell biology is the study of
cellular structure and functions
Histology is the study of
microscopic structure of tissues
Gross anatomy is the study of
structure that can be examined without a microscope
Systemic anatomy is the study of
structure of specific systems of the body such as the nervous or respiratory systems
Regional anatomy is the study of
specific regions of the body such as the head or the chest
Surface anatomy is the study of
surface markings of the body to understand internal anatomy through visualization and palpation
Imaging anatomy is the study of
internal body structure that can be visualized with techniques such as X-rays, MRI, CT scan, and other technologies for clinical analysis and medical intervention
Pathological anatomy is the study of
structural changes (gross to microscopic) associated with disease
Molecular physiology is the study of
functions of individual molecules such as proteins and DNA
Neurophysiology is the study of
functional properties of nerve cells
Endocrinology is the study of
hormones (chemical regulators in the blood) and how they control body function
Cardiovascular physiology is the study of
functions of the heart and the blood vessels
Immunology is the study of
the body’s defenses against disease-causing agents
Respiratory physiology is the study of
functions of the air passageways and lungs
Renal physiology
function of the kidney
Exercise physiology is the study of
changes in cell and organ functions due to muscular activity
Pathophysiology is the study of
functional changes associated with disease and aging
Level of Structural Organization
• chemical level • cellular level • tissue level • organ level • system level • organismal level
The Components of the Integumentary System
skin, and associated structures such as hair, fingernails, and toenails, sweat gland and oil gland
The Functions of the Integumentary System
protects the body; helps regulate body temperature; eliminates some wastes; helps make vitamin D; detects sensations such as touch, pain, warmth, and cold; stores fat and provide insulation
The Components of the Skeletal System
bones and joints of the body and their associated cartilages
