Flashcards in Branches of Anatomy (Exam 1) Deck (13):
0

Developmental anatomy

Study of structural changes that occur between conception and adulthood

1

Embryology

Studies changes from conception to the end of the 8th week of development

Most birth defects occur in this period

2

Gross/macroscopic anatomy

Study of large body structures visible to the naked eye

3

Systemic anatomy

Each of the body's 11 systems are studied separately

4

Regional anatomy

Body structures in one particular region of the body are examined at the same time

5

Microscopic anatomy

Study of structures too small to be seen using the naked eye, with a microscope

6

Cytology

Examines structural features of cells

7

Histology

Examines micro-thin slivers of tissue, have usually been stained, fixed, and mounted on a microscope slide

8

Radiological anatomy

Study of anatomy using x-ray technology

9

Ultrasound/sonography

High frequency sound waves strike internal organs and bounce back to a receiver on the skin

10

Computed tomographic scan (CT)

A low intensity x-ray tube is rotated through a 360 degree arc around the patient and the images are fed to a computer

11

Magnetic resonance imaging (MRI)

Radio waves are directed at a patient lying Ina chamber surrounded internally by a large electromagnetic field
H+ protons align, and then the radio waves are turned off and the ions return to their original place producing an image

12

Positron emission tomographic scan (PET)

Identifies the metabolic states of various tissues

Glucose is radioactively labeled, the glucose decays and gives off positrons, positrons collide with electrons giving off gamma rays, gamma rays pinpoint the cells that are metabolically active
