Superior
toward the head end or upper part of the body
Describe Anatomical position and explain its importance
Body is erect with feet slightly apart, palms facing forward and thumbs point away from the body. It is essential to understand the anatomical position bc most of the directional terms used refer to the body as if it were in this position, regardless of its actual position
Inferior
Away from the head end or toward the lower part of the body
Ventral
Toward the front of the body; in front of
Dorsal
Toward the back of the body; behind
Medial
Toward the midline of body
Lateral
Away from the midline of the body
Intermediate
between a more medial and more lateral structure
Proximal
Closer to the origin of the body part or the point of attachment of a limb to the body trunk
Distal
Farther from the origin of a body part or the point of attachment of a limb to the body trunk
Superficial
toward or at the body surface
Deep (internal)
Away from the body surface, more internal
Sagittal Plane
a vertical plane that divides the body into right and left
Midsagittal (median) Plane
the midline
Frontal Plane (coronal Plane)
divide the body into posterior and anterior parts (front and back)
Transverse Plane
divides body into top and bottom parts (superior and inferior)
Oblique Sections
cuts made diagonally (seldom used)
Dorsal body cavity (back)
contains both the cranial and the vertebral cavity, protects the nervous system organs
Cranial Cavity
located in the dorsal cavity, this cavity is the skull which protects the brain.
Vertebral (spinal) Cavity
Located in the dorsal cavity, the vertebral cavity encloses the spinal cord.
Ventral Body Cavity
the largest body cavity and it is the front cavity, which hold the Thoracic, abdominal and pelvic cavity.
Thoracic Cavity
Found in the ventral body cavity, this cavity protects the chest, lungs, heart, esophagus, trachea, etc.
Abdominoplevic Cavity
Found in the Ventral body cavity, this cavity houses the abdominal and pelvic cavities, which protects the stomach, spleen, liver, bladder, reproductive organs and the rectum.
Serous Membranes of the ventral body cavitie
The walls of the ventral body cavity and the outer surfaces off the organs it contains are covered by a thin, double layered membrane the serous membrane. The part of the membrane lining the cavity walls is called the parietal serosa. It folds in on itself to form the visceral serosa, covering the organs in the cavity.
