Chapter 1 - First look at anatomy Flashcards
(30 cards)
Study of the structure of the body
Anatomy
Study of the function of the body and its individual parts
Physiology
Examines structures that cannot be viewed by the unaided eye
Microscopic anatomy
Study of cells
Cytology
Study of tissues
Histology
Investigates structure and relationships of large body parts that are visible to the unaided eye
Gross/Macroscopic anatomy
Examines similarities and differences in anatomy of different species
Comparative
Investigates changes in structure within an individual from conception through maturity
Developmental
Concerned with development changes occurring prior to birth
Embryology
Examines all structures in a particular region of the body as one complete unit (skin, connective tissue and bones, muscles, nerves, and blood vessels of the neck)
Regional
Examines both superficial anatomic markings and internal body structures as they relate to the skin covering them
Surface
Studies gross anatomy of each system in the body
Systemic
Examines all anatomic changes resulting in disease
Pathology
Studies relationships among internal structures that may be visualized by specific medical imaging procedures (ultrasound, MRI, x-ray)
Radiology/Medical imaging
Investigates anatomic landmarks used before and after surgery
