Overview of Human Physiology and Pathophysiology Flashcards
Studies the structure of body parts and their relationships
Anatomy
morphology is derived from
Gr. Morphos = shape or form
Gr. ana means
“up”
tome means
“cutting”
16th century, Father of Anatomy

4 anatomy: levels of study
gross or macroscopic anatomy
surface anatomy
microscopic anatomy
developmental anatomy
Larger structures
can be seen with the naked eye
gross or macroscopic anatomy
gross or macroscopic anatomy approach of study:
regional anatomy
systemic anatomy
study of internal structures as they relate to the overlying skin surface
surface anatomy
locate the bump - 2nd pair of ribs are attached: top of the heart is located
sternal angle or angle of louis
locate the prominent bump, next 2 spine - location of the top of the heart at the back side
spinous process of 7th cervical vertebra (C-7)
- structures that cannot be seen with the naked eye
- structures can only be viewed with a microscope
microscopic anatomy
subdivisions of microscopic anatomy
cytology and histology
traces structural changes that occur in the body throughout the life span
developmental anatomy
concerns developmental changes that occur before birth
embryology
special terminology is used to prevent misunderstanding
language of anatomy
language of anatomy’s exact terms are used for:
position, direction, regions, structures
- person stands with erect feet together and eyes forward
- palms face anteriorly with thumbs pointed away from the body
- right and left always refers to the sides belonging to the person or specimen being viewed: never to the viewer
anatomical position
ventral and anterior are the same and so are dorsal and posterior
humans
ventral is on the inferior side and dorsal is on the superior side
four-legged animals
anterior and posterior body landmarks
axial region & appendicular region (thorax, abdomen, back)
regional terms
directional terms:
superior (cranial or cephalad), inferior (caudal), ventral (anterior), dorsal (posterior), medial, lateral, intermediate, proximal, distal, superficial, deep
