Chapter One Flashcards
Anatomy
Define Anatomy
it is the study and structure of form
Physiology
Define Physiology
it is the study of function of the body parts
it’s when someone study the function of body parts
Microscopic Anatomy
Define Microscopic Anatomy
structures that cannot be seen by the unaided eye
you have to look at the structures with the help of a microscope
Cytology
Define Cytology (cellular anatomy)
the study of the body cells and their internal structure
Histology
Define Histology
The study of body tissues
Gross Anatomy
Define Gross Anatomy (macroscopic anatomy)
study of structures that can be seen with the naked eye
structures you can see without a microscope ex. skeletal system
Systemic Anatomy
Define Systemic Anatomy
Anatomy of each functional body system
Regional Anatomy
Regional Anatomy
all of the stuctures in a particular region of the body as a complete unit
Surface Anatomy
Define Surface Anatomy
focuses on both superficial anatomic markings and the internal body structures that relate to the skin covering them
Comparative Anatomy
Define Comparative Anatomy
examines similarities and the differences in the anatomy of difference species
Embryology
Embryology
concerned specifically with developmental changes occuring prior to birth
Pathologic Anatomy
Pathologic Anatomy
examines all anatomic changes resulting from disease
Radiographic Anatomy
Define Radiographic Anatomy
Investigates the relationships among internal structures that may be visualized by specific scanning procedures
Physiologists
Define Physiologists
Examine the function of body structures, focusing on the molecular and cellular level
Cardiovasulcar Physiology
What is Cardiovascular Physiology?
When someone examines the functions of the heart and blood vessels
Neurophysiology
What is Neurophysiology?
it’s when somone examines how nerve impules travel throughout the nervous system
Repiratory Physiology
Define Respiratory Physiology
studies how respiratory gases are transferred by gas exchange between the lungs and the blood vessels
Pathophysiology
Define Pathophysiology
investigates the relationship between the functioning of an organ system and disease or injury to that organ system.
Metabolism
What is a Metabolism
The sum of all chemical processes that occur in an organism
Anabolism
What is Anabolism
small molecules are joined to form larger molecules
Catabolism
Define Catabolism
large molecules are broken down into smaller molecules
Chemical Level
What is the Chemical Level
Atoms and Molecules
Atom
Define Atom
it is the smallest unit of matter
Molecule
Define Molecule
two or more atoms combined
Macromolecules
What is a Macromolecule
Include proteins and DNA. Form specialized microscopic subunits called Organelles
carbohydrates, lipids (fats), proteins, and nucleic acids
Organelles
Define Organelles
Microscopic subunits
Cellular Level
Describe the Cellular Level
Consists of cells which are the smallest living structures and serve as the basic units of structure and function in organisms
Tissue Level
Describe the Tissue Level
Consists of tissues, which are groups of similar cells that perform common functions.
Organ Level
Describe the Organ Level
Composed of organs, which contain two or more tissue types that work together to perform specific, complex functions.
Organ System Level
Describe the Organ System Level
Contains related organs that work together to coordinate activities and achieve a common function.
ex. urinary system
Organismal Level
Describe the Organismal Level
highest level of structural organization in the body
Integumentary System
Describe the Integumentary System
Consists of the skin, mucous membranes, hair, and nails. It provides protection, prevents water loss and gain, synthesizes vitamin D, releases secretions, regulates body temperature, and houses sensory receptors.
Skeletal System
Describe the Skeletal System
Consists of bones, cartilages, ligaments, and joints. Provides support and protection, site of hematopoiesis, stores calcium and phosphorus, provides sites for ligament and muscle attacthments
Muscle System
Describe the Muscle System
Consists of muscles, produces body movement, generates heat when muscles contract.
Nervous System
Describe the Nervous System
Consists of nerves. It is a regulatory system that responds to sensory stimuli, and controls muscles and some glands. Also responsible for consciousness, intelligence, and memory.
Endocrine System
Endocrine System
Consists of glands and cell clusters that secrete hormones, maintain homeostasis of blood composition and volume, control digestive processes, control reproductive fucntions.
Ex. Thyroid gland
Cardiovascular System
Describe the Cardiovascular System
Consists of the heart, blood vessels, and blood. The heart moves blood through blood vessels in order to distribute hormones, nutrients, gases, and pick up waste products.
Lymphatic System
Lymphatic System
Transports and filters lymph and may participate in an immune response.
Respiratory System
Describe the Respiratory System
Responsible for exchange of gases between blood and the air between the lungs.
Urinary System
Describe the Urinary System
Filters the blood to remove waste products and biologically active molecules, concentrates waste products in the form of urine, and expels urine from the body.
Disgestive System
Describe the Digestive System
Mechanically and chemically digests food, absorbs nutrients, and expels waste products.
Male Reproductive System
Describe the Male Reproductive System
Produces male sex cells and male hormones.
Female Reproductive System
Describe the Female Reproductive System
Produces female sex cells, receives sperm from male, site of fertilization of oocyte, site of growth and development of embryo and fetus, produces and secretes breast milk for nourishment of newborn.
Anatomic Position
What is the Anatomic Position
Stands upright with the feet parallel and flat to the floor, the upper limbs are at the sides of the body, and the palms face anteriorly.
Anterior means front
Coronal Plane (frontal plane)
What is the Coronal Plane
Vertical plane that divides the body or organ into anterior and posterior parts. Anterior portion contains the chest and the posterior portion contains the back and buttocks
Transverse Plane (horizontal plane)
What is the Transverse Plane
Divides the body or organ into superior and inferior parts. The superior portion contains the chest and the inferior portion contains the abdomen.
