Study Notes
Anatomy Definition and Branches
- Anatomy is the study of the structure (morphology) of the human body and its parts.
- Anatomy is traditionally taught through dissection, the careful cutting apart of body structures.
-
Gross Anatomy/Macroscopic Anatomy studies the structure of the body with the naked eye. It can be broken into various branches such as:
- Systemic Anatomy studies the structure of specific systems of the body (nervous, respiratory, etc.).
- Regional Anatomy studies specific regions of the body (head, chest, etc.).
- Surface Anatomy studies the surface markings of the body to understand internal anatomy through visualization and palpation.
- Imaging Anatomy studies internal body structures using x-rays, CT scans, MRI, and other imaging technologies.
- Microscopic Anatomy/Histology studies the minute structure of the body using a microscope.
- Embryology studies the various stages of intrauterine development from the fertilized ovum up to birth.
Six Levels of Structural Organization
- Chemical Level: Atoms combine through chemical reactions to form molecules.
- Cellular Level: Molecules combine to form cells, the basic structural and functional units of an organism.
- Tissue Level: Groups of similar cells working together to perform a specific function (four basic types: epithelial, connective, muscular, and nervous).
- Organ Level: Structures composed of two or more different tissues working together to perform a particular function.
- System Level: Groups of related organs with a common function.
- Organismal Level: All the parts of the human body functioning together.
Anatomical Position
- The anatomical position is the standard reference pose for describing the location of structures and their relationships.
- The pose includes:
- Standing upright with face looking forward.
- Upper limbs by the side with palms facing forward.
- Lower limbs together with toes facing forward.
Anatomical Planes
-
Sagittal Planes are vertical planes parallel to the midline of the body.
- Median Sagittal Plane is a specific sagittal plane that divides the body into equal right and left halves.
- Coronal Planes divide the body into anterior (front) and posterior (back) parts.
- Transverse Planes (also called axial planes or horizontal planes) divide the body into superior (upper) and inferior (lower) parts.
Anatomical Directional Terms
- Superior: Above or higher in position; toward the head (e.g., the heart is superior to the liver).
- Inferior: Below or lower in position; toward the feet (e.g., the stomach is inferior to the lungs).
- Medial: Nearer to the midline (e.g., the heart is medial to the lungs).
- Lateral: Farther from the midline (e.g., the lungs are lateral to the heart).
- Proximal: Nearer to the attachment of a limb to the trunk or the origination of a structure (e.g., the humerus is proximal to the radius).
- Distal: Farther from the attachment of a limb to the trunk or the origination of a structure (e.g., the phalanges are distal to the carpals).
- Cephalic: Relating to the skull/head; toward the head (e.g., the stomach is more cephalic than the urinary bladder).
- Caudal: Relating to the tail; at or near the tail or inferior part of the body (e.g., the lumbar vertebrae are caudal to the cervical vertebrae).
- Anterior: Nearer to or at the front of the body (e.g., the sternum is anterior to the heart).
- Posterior: Nearer to or at the back of the body (e.g., the esophagus is posterior to the trachea).
- Ventral: Relating to the belly side of the body; toward the belly (e.g., the intestines are ventral to the vertebral column).
- Dorsal: Relating to the back side of the body; toward the back (e.g., the kidneys are dorsal to the stomach).
- Superficial: Toward or on the surface of the body (e.g., the ribs are superficial to the lungs).
- Deep: Away from the surface of the body (e.g., the ribs are deep to the skin of the chest and back).
- Ipsilateral: On the same side of the body's midline as another structure.
- Contralateral: On the opposite side of the body's midline from another structure.
Movements
- Flexion: Decreasing the angle between body parts.
- Extension: Increasing the angle between body parts.
- Dorsiflexion: Flexion at the ankle, so that the foot points more superiorly.
- Plantar Flexion: Extension at the ankle, so that the foot points inferiorly.
- Inversion: Movement of the foot, so that the sole faces in a medial direction.
