Branches of Anatomy (Exam 1)

Question 0

Embryology

Answer 0

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

Most birth defects occur in this period

Question 1

Developmental anatomy

Answer 1

Study of structural changes that occur between conception and adulthood

Question 2

Gross/macroscopic anatomy

Answer 2

Study of large body structures visible to the naked eye

Question 3

Systemic anatomy

Answer 3

Each of the body’s 11 systems are studied separately

Question 4

Regional anatomy

Answer 4

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

Question 5

Microscopic anatomy

Answer 5

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

Question 6

Cytology

Answer 6

Examines structural features of cells

Question 7

Histology

Answer 7

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

Question 8

Radiological anatomy

Answer 8

Study of anatomy using x-ray technology

Question 9

Ultrasound/sonography

Answer 9

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

Question 10

Computed tomographic scan (CT)

Answer 10

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

Question 11

Magnetic resonance imaging (MRI)

Answer 11

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

Question 12

Positron emission tomographic scan (PET)

Answer 12

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
