Chapter 1 Flashcards
The study of internal and external structures and the physical relationship between body parts
Anatomy
the study of how organisms perform their vital function
Physiology
(unchanging+standing) refers to the existence of a stable environment
Homeostasis
different molecules coming together to perform a specific function
Cell
a group of cells coming together to perform a specific function
Tissue
consists of multiple tissues coming together to perform a specific function
Organ
the interconnection of multiple organs working together to perform a complex function
Organ System
all organs working together to maintain life and health. This leads to the highest level of organization
Organism
What are the all of the Organ Systems
Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Reproductive
is the organ system that protects the body from various kinds of damage, such as loss of water or abrasion from outside. The system comprises the skin and its appendages
Integumentary System
The framework of the body, consisting of bones and other connective tissues, which protects and supports the body tissues and internal organs.
The Skeletal System
is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body
Muscular System
the bodily system that in vertebrates is made up of the brain and spinal cord, nerves, ganglia, and parts of the receptor organs and that receives and interprets stimuli and transmits impulses to the effector organs
Nervous System
is the collection of glands of an organism that secrete hormones directly into the circulatory system to be carried towards distant target organs.
Endocrine System
the system that circulates blood and lymph through the body, consisting of the heart, blood vessels, blood, lymph, and the lymphatic vessels and glands.
Cardiovascular System
is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of this system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body
Lymphatic System
is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of this system are lungs, which carry out this exchange of gases as we breathe
Respiratory System
consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). In this system, the process of digestion has many stages, the first of which starts in the mouth.
Digestive System
also known as the renal system, consists of the kidneys, ureters, bladder, and the urethra. Each kidney consists of millions of functional units called nephrons. … The urine is then passed through the ureters to the bladder, where it is stored.
Urinary System
or genital system is a system of sex organs within an organism which work together for the purpose of sexual reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to this system.
Reproductive System
The erect position of the body with the face directed forward, the arms at the side, and the palms of the hands facing forward, used as a reference in describing the relation of body parts to one another.
The Anatomical Position
Anatomical Positions:
front of the body
Anterior or Ventral
Anatomical Position:
back of the body
Posterior or Dorsal
Anatomical Position:
toward the middle of the body
Medial
Anatomical Position:
away from the middle of the body
Lateral
Anatomical Position:
Far from the bodies surface
Internal/Deep
Anatomical Position:
at or near the bodies surface
External/ Superficial
Anatomical Position:
In reference to limbs, Near Base
Proximal
Anatomical Position:
In reference to limbs, Away from Base
Distal
Anatomical Position:
Whole body, above
Superior
Anatomical Position:
Whole body, below
Inferior
Anatomical Position:
Toward Head
Cranial
Anatomical Position:
Toward potential tail
Caudal
A movement that reduces the angle between two articulating bones; the opposing extensions.
Flexion
An increase in the angle between two articulating bones, the opposition of flexion
Extension
conducting or conducted inward or toward something (for nerves, the central nervous system; for blood vessels, the organ supplied).
Afferent
Carrying motor impulses away from a central organ or part, as a nerve that conducts impulses from the central nervous system to the periphery of the body.
efferent
The movement of a limb away from the midline of the body. The opposite of this is adduction.
abduction
s the movement of a body part toward the body’s midline. So, if a person has their arms straight out at the shoulders and brings them down to their sides, it is the opposite of abduction.
adduction
the sole of the foot or planta
plantar
the palm of hand
palmar
This body plane lies at a right angles to the long axis of the body. It divides into Superior and Inferior
Transverse Plane
this body plane runs along the long axis of the body. It extends laterally and divides the body into anterior and posterior
Frontal or Coronal Plane
This body planes runs along the long axis it extends from to back and divides the body into left and right portions
Sagital
A cut that passes along the bodies midline and divides the body into right and left is called
Midsagital Section
the chest cavity. is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia).
Thoric Cavity
is the thin fluid-filled space between the two pulmonary pleurae (visceral and parietal) of each lung. A pleura is a serous membrane which folds back onto itself to form a two-layered membranous pleural sac.
the pleural cavity
is the central compartment of the thoracic cavity surrounded by loose connective tissue, as an undelineated region that contains a group of structures within the thorax. The mediastinum contains the heart and its vessels, the esophagus, trachea, phrenic and cardiac nerves, the thoracic duct, thymus and lymph nodes of the central chest.
Mediastinum
is a body cavity that consists of the abdominal cavity and the pelvic cavity. It contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, and most of the small and large intestines. It also contains the urinary bladder and internal reproductive organs.
Abdominoplevic Cavity
is hardly an empty space. It contains a number of crucial organs including the lower part of the esophagus, the stomach, small intestine, colon, rectum, liver, gallbladder, pancreas, spleen, kidneys, and bladder.
Abdominal Cavity
is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor. This Cavity primarily contains reproductive organs, the urinary bladder, the pelvic colon, and the rectum.
Pelvic Cavity
is located along the dorsal (posterior) surface of the human body, where it is subdivided into the cranial cavity housing the brain and the spinal cavity housing the spinal cord. The two cavities are continuous with one another.
Dorsal Body Cavity
is the space formed inside the skull. It is part of the dorsal body cavity. The brain occupies this cavity which is lined by the meninges and which contains
Cranial Cavity
(or vertebral canal) is the space in the vertebral column formed by the vertebrae through which the spinal cord passes. It is a process of the dorsal body cavity. This canal is enclosed within the vertebral foramen of the vertebrae.
