A First Look at Anatomy Flashcards
Studies the gross anatomy of each system e.g. digestive system, circulatory system
Systemic Anatomy
Studies all structures in a particular body region e.g. the head, regions of gun shot wounds.
Regional Anatomy
Study of the landmarks outside of the body that are created by underlying structures and their medical importance
Surface Anatomy
What forms an organism?
Atoms- Molecules- Cells- Tissues- Organs- Organ System
Occurs in 1 in 7000-8000 persons, usually without any health problems. The internal organs switch the typical side they are found. (Heart on the right side, liver on the left etc.) In males with this condition, the right testicle hangs lower than the left. In normal males, the left testicle hangs lower.
Situs Inversus
Divides the body into upper and lower portions
Transverse, Cross-sectional or horizontal plane
Midsaggital (median) plane
Divides the body in equal left and right parts. A saggital plane is when is either left or right of the midline.
Anterior (ventral)
In front of
Posterior (dorsal)
In back of
Superior (cranial or rostral)
closer to the head or above
Inferior (caudal)
Closer to the feet
Medial
Toward the midline of the body
Lateral
away from the midline of the body
Internal
deep
external
superficial
Section and Plane difference
Section implies an actual cut or slice. Plane implies an imaginary flat surface passing the body.
Divides the body lengthwise into front and back.
Coronal or Frontal Plane
closest point of attachment to trunk or midline or closest to any point of reference that is given.
proximal
Furthest from point of attachment to trunk or midline or furthest from any point of reference that is given.
Distal
Axial Region
1) Head. 2) Neck. 3) Trunk (chest and abdominal regions)
Appendicular region
Upper extremity and lower extremity.
Posterior body cavity
Cranial Cavity and Vertebral Cavity
Anterior body cavity
Thoracic Cavity and Adbominopelvic cavity. These two cavities are separated by a skeletal muscle called the diaphragm
It is found within the Thoracic cavity. It contains the heart, thymus, esophagus, trachea, and several major blood vessels.
