Study Notes
Human Anatomy: An Orientation
- Anatomy is the study of the structure of the human body
- Physiology is the study of body function
Overview of Anatomy
- Anatomy branches include:
- Gross anatomy
- Microscopic anatomy (histology)
- Surface anatomy
- Anatomical terminology is rooted in ancient Greek and Latin
- Provides a worldwide standard nomenclature
Hierarchy of Structural Organization
- Chemical level: Atoms form molecules
- Over 90% of the human body is comprised of only four atoms: Carbon, Nitrogen, Oxygen, and Hydrogen
- Cellular level: Cells and their subunits (e.g., red blood cells, neurons)
- Tissue level: Groups of cells performing common functions (epithelial, connective, muscle, nervous)
- Organ level: Discrete structures composed of more than one tissue (e.g., liver, brain, heart)
- Organ system level: Organs working together (e.g., digestive system)
- Organismal level: The result of all simpler levels functioning together
Anatomical Position
- The standard reference point for directional terms
- Person stands erect, feet together, eyes forward
- Palms face anteriorly, thumbs pointed away from the body
Directional Terminology
- Standardized terms describing direction in relation to anatomical position
- Paired terms with opposite meanings (e.g., superior/inferior, anterior/posterior)
Orientation Terms (examples)
-
Superior (cranial): Toward the head, upper part
-
Inferior (caudal): Away from the head, lower part
-
Anterior (ventral): Front of the body
-
Posterior (dorsal): Back of the body
-
Medial: Toward the midline of the body
-
Lateral: Away from the midline of the body
-
Proximal: Closer to the origin or attachment
-
Distal: Further from the origin or attachment
-
Superficial: Toward the body surface
-
Deep: Away from the body surface
-
Ipsilateral: On the same side (e.g., right arm and right leg)
-
Contralateral: On opposite sides (e.g., right arm and left leg)
Regional Terms
- Named sections of the body (e.g., cephalic, cervical, abdominal)
- Specific anatomical regions
- Axial region (head, neck, trunk)
- Appendicular region (limbs)
- Specific anatomical regions
Body Planes and Sections
- Coronal (frontal) plane: Divides the body into anterior and posterior portions (front and back)
- Median (midsagittal) plane: Divides the body into left and right halves (through the midline)
- Transverse plane (horizontal plane): Divides the body into superior and inferior portions (top and bottom)
- Oblique plane: Cuts at an angle
Body Cavities and Membranes
- Body cavities: Internal spaces containing vital organs
- Dorsal body cavity: Cranial cavity (brain) and Vertebral cavity (spinal cord)
- Ventral body cavity: Thoracic cavity (heart and lungs), Abdominal cavity (digestive viscera), and Pelvic cavity (urinary bladder and reproductive organs)
- Membranes: Thin sheets of tissue lining cavities, reducing friction
- Serous membranes: Line closed body cavities
-Two layers:
- Parietal serosa: Lines the cavity walls
- Visceral serosa: Covers organs within the cavity
- Serous membranes: Line closed body cavities
-Two layers:
- Examples of serous cavities
- Pleural (lungs)
- Pericardial (heart)
- Peritoneal (abdominopelvic organs)
Abdominal Regions and Quadrants
- Dividing the abdomen into sections for easier description and localization.
- Nine regions: for more detail in describing locations
- Four quadrants: for a general location
