Intro to the Human Body Flashcards
division of the anterior (ventral cavity that houses the abdominal and pelvic viscera
Abdominpelvic Cavity
assembly of more complex molecules from simpler molecules
Anabolism
standard reference position used for describing locations and directions on the human body
Anatomical Position
science that studies the form and composition of the body’s structures
Anatomy
describes the front or direction toward the front of the body; also referred to as ventral
Anterior
larger body cavity located anterior to the posterior (dorsal) body cavity; includes the serous membrane-lined pleural cavities for the lungs, pericardial cavity for the heart, and peritoneal cavity for the abdominal and pelvic organs; also referred to as ventral cavity
Anterior Cavity
breaking down of more complex molecules into simpler molecules
Catabolism
describes a position below or lower than another part of the body proper; near or toward the tail (in humans, the coccyx, or lowest part of the spinal column); also referred to as inferior
Caudal
medical imaging technique in which a computer-enhanced cross-sectional X-ray image is obtained
Computed Tomography (CT)
compares values to their normal range; deviations cause the activation of an effector
Control Center
describes a position above or higher than another part of the body proper; also referred to as superior
Cranial
division of the posterior (dorsal) cavity that houses the brain
Cranial Cavity
describes a position farther from the surface of the body
Deep
changes an organism goes through during its life
Development
process by which unspecialized cells become specialized in structure and function
Differentiation
describes a position farther from the point of attachment or the trunk of the body
Distal
describes the back or direction toward the back of the body; also referred to as posterior
Dorsal
posterior body cavity that houses the brain and spinal cord; also referred to the posterior body cavity
Dorsal Cavity
organ that can cause change in a value
Effector
two-dimensional, vertical plane that divides the body or organ into anterior and posterior portions
Frontal Plane
Study of the larger structures of the body, typically with the unaided eye; also referred to macroscopic anatomy
Gross Anatomy
process of increasing in size
Growth
steady state of body systems that living organisms maintain
Homeostasis
describes a position below or lower than another part of the body proper; near or toward the tail (in humans, the coccyx, or lowest part of the spinal column); also referred to as caudal
Inferior
describes the side or direction toward the side of the body
Lateral
medical imaging technique in which a device generates a magnetic field to obtain detailed sectional images of the internal structures of the body
Magnetic Resonance Imaging (MRI)
describes the middle or direction toward the middle of the body
Medial
sum of all of the body’s chemical reactions
Metabolism
study of very small structures of the body using magnification
Microscopic Anatomy
homeostatic mechanism that tends to stabilize an upset in the body’s physiological condition by preventing an excessive response to a stimulus, typically as the stimulus is removed
Negative Feedback
range of values around the set point that do not cause a reaction by the control center
Normal Range
chemical obtained from foods and beverages that is critical to human survival
Nutrient
functionally distinct structure composed of two or more types of tissues
Organ
group of organs that work together to carry out a specific function
Organ System
living being that has a cellular structure and that can independently perform all physiologic functions necessary for life
Organism
sac that encloses the heart
Pericardium
serous membrane that lines the abdominopelvic cavity and covers most of the organs found there
Peritoneum
science that studies the chemistry, biochemistry, and physics of the body’s functions
Physiology
imaginary two-dimensional surface that passes through the body
Plane
serous membrane that lines the pleural cavity and covers the lungs
Pleura
the smallest independently functioning unit of all organisms; in animals, a cell contains cytoplasm, composed of fluid and organelles
Cell
mechanism that intensifies a change in the body’s physiological condition in response to a stimulus
Positive Feedback
medical imaging technique in which radiopharmaceuticals are traced to reveal metabolic and physiological functions in tissues
Positron Emission Tomography (PET)
describes the back or direction toward the back of the body; also referred to as dorsal
Posterior
posterior body cavity that houses the brain and spinal cord; also referred to as dorsal cavity
Posterior Cavity
force exerted by a substance in contact with another substance
Pressure
face down
Prone
describes a position nearer to the point of attachment or the trunk of the body
Proximal
study of the structures that contribute to specific body regions
Regional Anatomy
process by which worn-out cells are replaced
Renewal
process by which new organisms are generated
Reproduction
ability of an organisms or a system to adjust to changes in conditions
Responsiveness
two-dimensional, vertical plane that divides the body or organ into right and left sides
Sagittal Plane
in anatomy, a single flat surface of a three-dimensional structure that has been cut through
Section
(also, receptor) reports a monitored physiological value to the control center
Sensor
membrane that covers organs and reduces friction; also referred to as serous membrane
Serosa
membrane that covers organs and reduces friction; also referred to as serosa
Serous Membrane
ideal value for a physiological parameter; the level or small range within which a physiological parameter such as blood pressure is stable and optimally healthful, that is, within its parameters of homeostasis
Set Point
division of the dorsal cavity that houses the spinal cord; also referred to as vertebral cavity
