Chapter 2: The Human Body-An Overview Flashcards
Anatomy
study of human body structure
Morphology
study of form and shape
Physiology
study of body function
Gross Anatomy
examining the human body w/naked eye through dissection and pro-section
Developmental Anatomy
structural changes that occur throughout life and the effects of aging
embryology
how body structures and form before birth
Pathological Anatomy
structural changes due to disease and the disease itself
Radiographic Anatomy
study of internal body structures
Functional Morphology
functional properties of body structure and design
Hierarchy of Structural Organization
Chemical, cellular, tissue, organ, organ system, and organismal level
Anatomical Position
A person standing upright, feet flat and forward, palms facing forward, and thumbs pointed away
Regional Terms
names of specific body areas
Characteristics Common to All Vertebrates
Tube-within-a-tube, bilateral symmetry, dorsal hollow nerve cord, notochord and vertebrae, segmentation, and pharyngeal pouches
Body’s 2 Large Cavities
Dorsal (posterior) body cavity and ventral (anterior) body cavity
Dorsal Body Cavity
closed-membrane space which houses the CNS and is located medially on the posterior of the head and trunk
contains: cranial and vertebral cavities
Cranial Cavity
contains: brain, various cerebral blood vessels, the pituitary gland, and roots of the cranial nerves
Vertebral Cavity
Contains: spinal cord, various spinal blood vessels, adipose tissue, and roots of spinal nerves
Dorsal Body Cavity Linings
3 connective layers (the meninges): dura mater, arachnoid, and pia matter
Intracranial Space
protects the brain and CNS within the cranial cavity
Ventral Body Cavity
houses various internal organs and is located medially on the anterior trunk
contains: thoracic cavity and abdominopelvic cavity
Thoracic Cavity
contains: heart, lungs, and organs of the mediastinum
Abdominopelvic Cavity
contains: abdominal cavity (stomach, liver intestines, and spleen) and pelvic cavity (urinary bladder, some reproductive organs, and distal colon)
Serous Membrane
lines internal body cavities (i.e. heart,lungs, and abdominal cavity)
Mediastinum
located within the thoracic cavity, lacks serous membranes, and houses the pericardial cavity
Serous Cavities
a slit-like space lined by a serous membrane
ex: pleura, pericardium, and peritoneum
Abdominal Quadrants
l RUQ l LUQ \_\_\_\_l\_\_\_\_ RLQ l LLQ l
Retroperitoneal Space
Anatomical space in the abdominal cavity behind (retro) to the peritoneum
contains: glands, ureter, kidneys, and lots of blood vessels
Pleural Effusions
abnormal fluid collection in the chest between the visceral and pleural surfaces
treatment: drainage tube
Pericarditis
swelling and irritation of the pericardium
treatment: pharmaceutical and rarely surgical
