Lesson 1A: Overview of Human Physiology and Pathophysiology Flashcards
Studies the structure (morphology; Gr.
Morphos – shape or form) of body parts
and their relationships.
Anatomy
meaning of Greek prefix ana-
“up”
meaning of Greek tome
“cutting”
a Belgian Physician who is considered as the Father of Anatomy
Andreas Vesalius
(1514-1564)
7-volume collection of anatomic drawings by Vesalius in 1543
De Humani Corporis Fabrica
“On The Workings of the Human Body”
study of larger anatomical structures that CAN be seen with the naked eye
Gross or Macroscopic Anatomy
two general approaches of Gross or Macroscopic Anatomy
- Regional Anatomy
- Systemic Anatomy
study of internal structures as they relate to the overlying skin surface
Surface Anatomy
examples of anatomic landmarks in surface anatomy
- Sternal Angle or Angle of Louis
- Spinous process of 7th cervical vertebra (C-7)
how do you find the Sternal Angle or Angle of Louis?
locate the bump where the 2nd pair of ribs are attached; located at the top of the heart
how do you find the 7th cervical vertebra (C-7)?
locate the prominent bump, next 2 spine – location at the top of the heart at the back side
study the structures that CANNOT be seen with the naked eye and can ONLY be viewed with a microscope
Microscopic Anatomy
2 subdivisions of Microscopic Anatomy
- Cytology
- Histology
traces structural changes that occur in the
body throughout the life span
Developmental Anatomy
concerns developmental changes that occur
BEFORE birth
Embryology
Exact terms are used for
- Position
- Direction
- Regions
- Structures
Person stands erect with feet together
and eyes forward
Anatomical Position
palms in anatomical position
palms face anteriorly with thumbs
pointed AWAY from the body
Right and left always refers to ____
sides belonging to the person or specimen being viewed – NEVER to the viewer
Four legged animals have a different anatomical
position than humans.
Their ventral is on the inferior side and dorsal is on the superior side.
human anatomical
position
ventral and anterior are the same and so are dorsal
and posterior
Regional Terms
- Anterior
- Posterior
Directional Terms
- Superior (cranial or cephalad)
- Inferior (caudal)
- Ventral (anterior)
- Dorsal (posterior)
- Medial
- Lateral
- Intermediate
- Proximal
- Distal
- Superficial
- Deep
toward the head end or upper part of a structure or the body; above
Superior (cranial or cephalad)
away from the head end or toward the lower part of a structure the body; below
Inferior (caudal)
toward or at the front of the body;
in front of
Ventral (anterior)
