Chapter One: the human body Flashcards
Physiology
The FUNCTION of the body, how the body parts work and carry out their life-sustaining activities.
Define Anatomy
Studies the Structure of body parts and their relationships to one another.
Define regional Anatomy
All the structures (muscles, bones, blood vessels, nerves, etc.) in a particular region of the body, such as the abdomen or leg, are examined at the same time.
Systemic Anatomy
Body structure is studied system by system. for example for the cardiovascular system, you would examine the heart and the blood vessels of the entire body.
Surface anatomy
The study of internal structures as they relate to the overlying skin surface. You use surface anatomy when you identify the bulging muscles beneath a bodybuilder’s skin.
Microscopic anatomy
Deals with structures too small to be seen with the naked eye.
Cytology
study of the Cells of the body
Histology
the study of tissues
Developmental anatomy
structural changes that occur in the body throughout the life span.
Embryology
Subdivision of developmental anatomy, developmental changes that occur before birth.
Renal Physiology
concerns kidney function and urine production
Neurophysiology
explains the workings of the nervous system
Cardiovascular physiology
examines the operation of the heart and blood vessels.
Cells are the smallest units of living things.
True or False?
True
Atoms form…
Molecules
Molecules form…
Organelles
Tissues
are groups of simliar cells that have a common function.
The four basic types of tissue in the human body are…
Epithelium, muscle, connective tissue and nervous tissue
Epithelium…
covers the body surface and lines it’s cavities.
Muscles provide…
movement
Connective tissue….
supports and protects body organs
Nervous Tissue…
Provides a means of rapid internal communication by transmitting electrical impulses.
Contractility
The muscles cell’s ability to move by shortening
ATP
The energy-rich molecules that power cellular activities
Integumentary system example
Skin, Hair, nails
Skeletal system example:
Joint, bones
Muscular System example:
Skeletal muscles
Nervous System Example:
Brain, Nerves, spinal cord
