1A Flashcards
Biology
The study of living organisms.
Physiology
Subdivision of biology that is concerned with the functioning of the body.
Attempts to explain the physical and chemical processes that occur in the body.
Anatomy
Subdivision of biology that is concerned with the form, structure or morphology of the body.
Where does the term “anatomy” originate?
Greek; Ana=apart, Tomy=cut
Where does the term “dissect” originate?
Latin; Dis=apart, Sectare=cut
Cytology
Subdivision of anatomy meaning the study of cells.
Where does the term “cytology” originate?
Greek; Kytos=cell, Logos=knowledge of
Histology
Subdivision of anatomy meaning the study of tissues.
Where does the term “histology” originate?
Greek; Histo=tissue, Logos=knowledge of
Gross Anatomy
Subdivision of anatomy meaning the study of structure visible with the naked eye.
Surface Anatomy
Subdivision of anatomy meaning the study of the surface structures.
Developmental Anatomy (Embryology)
Subdivision of anatomy meaning the development of the body prior to birth.
Comparative Anatomy
Subdivision of anatomy comparing human structures to that of other animals.
Radiology
Subdivision of anatomy using radiation to visualize internal body structure.
Anatomical Pathology
Subdivision of anatomy meaning the study of tissue that departs from the normal and thus is diseased.
List the Organization of the body from smallest to largest.
Cell, tissue, organ, organ system, body.
Cell
Smallest unit of living matter and the characteristic building block of all plant and animal tissues.
Tissue
Collection of cells of similar structure and function.
Organ
Consists of two to more tissues blended in such a way as to form a structure, which can perform one function or related functions.
Organ System
Consists of one or more organs that act together in performing a major function of the body.
Body
Composed of the 12 organ systems.
Regional Method of Study
According to the natural subdivisions of the body.
- Head: facial region, cranium
- Neck
- Thorax
- Abdomen
- Pelvis
- Back (posterior aspect of thorax, abdomen, and pelvis)
- Trunk (combination of thorax, abdomen, pelvis, and back)
- Upper Limb (extremity): pectoral region, arm, forearm, and hand
- Lower Limb (extremity): gluteal region, thigh, leg, and foot
Systematic Method of Study
According to the major body systems; collections of organs that perform related functions.
Name the 12 Organ Systems.
Cardiovascular or Circulatory, Lymphatic, Respiratory, Digestive, Urinary, Integumentary, Skeletal, Muscular, Articular, Nervous, Endocrine, Reproductive
Cardiovascular or Circulatory System
Structures: Heart, blood vessels
Functions: Transports nutrients and oxygen cells, removes waste molecules that are excreted from the body.
Lymphatic System
Structures: Lymphatic vessels, nodes, supporting lymphocytes, and the lymphoid organs
Functions: Protects body from disease by purifying fluid. Involves white blood cells that produce antibodies.
