First Look at Anatomy Flashcards
Identify midsagittal, transverse (cuts perpendicularly into long axis making up superior and inferior parts), and coronal (divides into anterior and posterior) positions.
-Cuts into left and right
-Cuts perpendicularly
-Divides into anterior and posterior positions
Medial
Toward or at the midline of the body
Ex: heart is medial to the arms
Proximal vs distal
Closer to the origin of the body part or the attachment.
Ex: the elbow is proximal to the wrist
What are the two major divisions of the body?
-Axial
Head, neck, and trunk (Thorax and abdomen)
-Appendicular
Limbs
Describe the regional terms of the specific body areas.
/
Describe the dorsal body cavities
-Cranial cavity
-Vertebral cavity
Describe the ventral body cavities
-Thoracic cavity (contains heart and lungs)
-Abdominal cavity (contains digestive viscera)
-Pelvic cavity (contains urinary bladder, reproductive organs, and rectum)
Mediastinum
- Superior mediastinum (Houses thymus gland, trachea, esophagus, aorta)
- Pericardial cavity ( Encloses heart)
Characteristics of Living Things
-Organization
-Metabolism
-Growth and Development
-Responsiveness
-Adaptation
-Regulation
-Homeostasis
-Reproduction
Hippocrates (Father of Medicine)
established a medical practice
based on the study of human body
Herophilus (Father of Anatomy)
in Alexandria, Egypt becomes
the first to publicly dissect human bodies.
Galen (Prince of Physicians)
stressed the importance of experimentation in medicine. He wrote significant treatises on medicine and anatomy.
Leonardo da Vinci
begins his anatomical studies through dissection.
Nine divisions used primarily by
anatomists
/
Serous membrane or serosa
Parietal serosa lines internal body cavity walls
Visceral serosa covers internal organs (viscera)
Layers separated by slit-like cavity
filled with serous fluid. Fluid secreted by both layers of membrane.
Pericardium- serous membrane of heart
Pleurae- serous membrane of lungs
Peritoneum- serous membrane of abdominopelvic cavity
